    I´m on a trip, and of course, I have brought a radio to sample some of the local broadcast offerings. This evening, I am in Panama City (Panama).

    There seems to be an aggressive element to the culture here that comes through on the radio programming. Some of the music stations that are live play station IDs over the music in the middle of the song. The DJ often jumps in and talks over the music in the middle of the song, doing what some call "pot whipping." That is where the DJ pulls down the fader for the music source to duck the music while he talks. Overall, DJing and board opping sounds a bit sloppy on the stations that I have been listening to.

    I am on a terminal at the hotel that restricts login sessions to 10 minutes, so I have to keep my comments brief. Having to use a Spanish keyboard layout adds an extra layer of difficulty because the punctuation marks are not in the right places.

    One thing I noticed early on is that the hotel clock radio in this hotel are FM only. In the phone book, the yellow pages entry for radio stations has a section specifically for FM Stereo stations. In other words, FM is marketed very aggressively here. Nonetheless, there are many radio stations on both bands, though a number of the AMs are FM simulcasts.

    The radio that I brought is my not-so-trusty Sony SRF-42. Doing an AM bandscan, the quality of the different stations varies quite a deal. There are a number of stations on AM that are using old transmitters that have high levels of incidental phase modulation. Two stations have a "rushing" noise in the L-R channel that sound like oscillator phase noise. One station has a very strong 120Hz component in the L-R channel that causes the SRF-42´s detector to have trouble locking onto the signal. Nobody on AM is doing HD Radio or AM Stereo in this city. Many of the AM stations have very distorted audio, and one, though not sounding very distorted, splatters quite a bit. Some of the stations seem to be close-spaced, possibly by only 30 kHz. The splatterbox station actually interferes with a local neighbor on the dial.

    Some of those countries don't observe 5mv/m and 25mv/m protection rules. I don't know if that applies to Panama or not.

    How is DX under those crowded conditions? ... or do many of the AMs sign off/reduce power at night?

    Sorry guys, I have been away from any kind of Internet access for the last few days--not that I mind :-).

    AM reception was OK but not great in the hotel in Panama City. The FM dial had very strong signals that overloaded both the hotel clock radio and my Walkman. I did hear some heterodynes from off-frequency transmitters at night.

    After Panama City, I flew to Bocas del Toro. The place where I stayed was a set of wood-framed buildings a few miles from the island miles away from the nearest power lines. DX was somewhat interesting there. First of all, with some patience, I could hear signals on the expanded band. All of these signals were very weak and in English, suggesting that I was hearing US stations. It appears that nobody else uses the expanded band, other than Mexico and Canada. Listening to the other frequencies on the dial, I heard mostly Spanish, with some English from Jamaican stations. I heard a lot of Colombian stations, one from El Salvador, and I think one from Nicaragua. There were a lot of off-frequency signals that caused audible heterodynes. There was one real crap-can transmitter on 1510 kHz (location unknown) that wobbled some 200-300 Hz in frequency with the modulation. There was also a signal that was just a loud hiss, which I could hear both in Panama City and Bocas del Toro. At first, I thought that this was a transmitter that was being fed from an off-air pickup of a FM station, and the FM signal was lost. However, now I´m thinking that this must be the 1140 kHz Cuban jammer that I read about years ago. Overall, the signal levels were much lower than what I´m used to hearing from blowtorches like KGO, suggesting that there are no big 50kW flamethrowers in Central America. From what I have seen elsewhere, stations here typically use 1 or 5 kW. There were also no frequencies that were dominated by one station. Most of the frequencies sounded like our regional channels, with a few that were closer to the mayhem of our graveyard channels.

    What has excited me somewhat about this trip is that I am now hearing for myself these FM national stations that I have previously read about. Unlike in Panama City, the AM dial is virtually dead in smaller communities, such as Bocas del Toro. In Bocas del Toro, I counted 29 FM signals and just one AM (660) that was a simulcast of 106.3. That AM station was off the air for most of my stay. Both of these stations were part of a network programmed from Panama City. The only station that I confirmed to be local was Imagen Estereo 97.9. They signed off the programming sometime around 9:00 PM but left the transmitter on. At night, I could hear several dead carriers on FM. It seems that there are many different ways that these FM networks distribute their audio. I speculate that analog telephone lines and over-the-air pickup are common, as some of the stations had somewhat noisy signals with faint whines and crackles, and small amounts of 60Hz hum could be heard on many of the stations. One of the networks (Radio Ancon) sounded as if it were fed by over-the-air pickup of their Panama City AM outlet with a wide bandwidth receiver (there was 120 Hz hum and occasional static crashes). Modulation levels seemed to be all over the place, and several of the stations were mono. In the days after my stay in Bocas, I saw the carcasses of at least two AM local stations (single towers not supporting any antennas but not radiating a signal). From these observations, I concluded that the poverty of rural Panama combined with competition from the big city FM networks have made local community radio economically unfeasible there. On top of that, the FM dial is full.

    There were a number of programming formats on the air with surprisingly little duplication of formats for the large number of signals. There were some full-service stations, news, some public affairs programming, sports, one station that played jazz and classical (in mono), some English language music, various styles of Spanish language music inspired by Cuban music, cumbia, and by various Caribbean Styles, such as reggae.

    To be continued (I am now in San Jose, Costa Rica)....

    Wow! great set of observations, sounds like a fine mini DXpedition!

    Grey line map seems to indicate possible US East coast reception in the evening and West coast possibilities in the early morning hours.

    Alfredo, thanks for the DX travelouge! You are a lucky guy, I don't get to travel much, in fact a trip to Scappoose is a thrill for me.

    And I'm going to start a band and name it "Splatterbox"! (see post #2)

    Thank goodness that mast hasn´t fallen! I will have to replace the corkscrews with concrete anchors and tighten the guy wires this summer because things are getting somewhat loose.

    I will post my Costa Rica radio observations soon. However, one thing that has really shocked me (fortunately not in a literal sense yet) is the concept of safety in Costa Rica. For instance:

    * Most of the cabs don´t have seat belts for passenger use.
    * People drive like maniacs here, and it is common practice for motorcyclists and bicyclists to sandwich themselves in between lanes of traffic.
    * A lot of building and service wiring looks like it was hacked together, with wires of seemingly random gauges being put in seemingly random arrangements. Either electrical code is non-existent here or it is not enforced.
    * Knife switches are acceptable for use as service disconnects or to switch large loads. In rural areas, it is common to see a three-pole knife switch next to the electric meters. Some of these switches have plastic covers over the contacts, but some don´t!
    * Electric instant water heaters built into the showerhead seem to be common in the hostels here. These units are called¨"Maxi Shower" and are made by Lorenzetti. They are rated 120V at 50A. The wiring seems to me on the skinny side for that high a current draw. One of the showers at the hostel where I´m staying tonight has a two-pole knife switch and fusible strips in the shower to provide a disconnect for the Maxi Shower! The contacts and fusible strips are exposed!!

    Lorenzetti Electric Shower

    Water and electricity; sounds like a really good mix, right? If you live in South America and have had a warm shower at night, chances are you've used one of these US outlawed shower heads at some point. It's an interesting experience.

    The first step, is to turn on the massive, 30 amp, sparking, electric switch, which is probably on loan from Dr. Frankenstein. It's scary just to touch the thing. Next, you turn the water on. As the water comes out, there is a gurling/crackling sound which sounds like the water is being electrocuted, which it is. If you stand directly under the water, you will get a slight tingling from the bled off electricity surging through the water, and if you are really unlucky, when you grab the faucet to turn the water off, you'll feel a solid, tingling, zap. Then comes the scariest part; turning of the Frankenstein switch with wet, dripping hands . . .

    Welcome to the Lorenzetti Maxi Ducha shower head.

    That must be what they mean on the "Vacation to remember!" brochures!

    I've been to Puerto Rico a few times and although it is a long-time U.S. territory, in some of the outlying areas, building code enforcement is seemingly several decades away.

    Ha ha ha ha! I forgot to mention that those Lorenzetti shower heads are not grounded!! The water pipes are made of plastic. I figured that if I should feel the slightest tingle while in the shower, I need to jump out of there right away! I almost feel like stopping at an electrical supply store and buying a knife switch as a souvenir.

    The shower head´s heater is activated by the water flow, so turning on the knife switch is optional. You know that the shower head is working because it makes an eerie hissing sound. In the bathroom in this hostel that has the knife switch, the connections for the bathroom light are tapped off the input to the knife switch, and the wire run along the bathroom wall and under the tile grout! Thus, when the water flow is sufficient to trigger the shower head, the light dims!!

    I returned to Portland yesterday afternoon. Here is the rest of my travelogue in bits and pieces. I can elaborate on other non-radio things, like food & beverages, people, wildlife, and weather, if anyone is interested.

    I spent Friday and Saturday night in Panama city. The plan was to stay in Bocas del Toro Sunday night, but the stay was extended to Monday night due to my travel companion falling ill. On Tuesday, we were off to the next stop, Punta Mona, Costa Rica. The route there was somewhat circuitous, and I think that the cabbies took advantage of us to some extent. Travel by bus is a lot cheaper.

    For reference, I was able to find an official table of AM radio stations in Costa Rica at http://www.controlderadio.go.cr/documentos/Radiodifusion%20Sonora%20Emisoras%20AM.pdf
    The biggest signals over there are 20 kW, and I suspect that most, if not all of these are non-directional. 1580 and 1600 seem to be their equivalent of the "graveyard" channels.

    We stayed at an organic farming educational center in Punta Mona Tuesday night. This, like Punta Caracol "Acqua Lodge" in Bocas del Toro was an off-the-grid place. No electrical service or roads were available in either location. Electricity was generated with solar panels, and transportation was by boat. Punta Mona was only some 30 miles from Bocas del Toro. However, a quick spin of the FM dial showed that the only Bocas del Toro signal that was still relatively strong was the audio from a station on Channel 6 in that area. The rest of the dial was silent with a few murmurs around 100 MHz. I didn't do much more listening from this location.

    The next day, we headed to Manzanillo (a small town on the Caribbean shore) and caught the bus to Puerto Viejo. On the bus, I noticed that the Channel 6 audio was gone, and there were a few signals that were very weak and had a lot of picket-fencing. One of these stations had very serious overdeviation that made it almost unlistenable. They were playing English-language oldies at the time. The AM dial was empty, save for occasional interference from the overhead power lines (I later read that the gravel road, as well as the power lines, between Puerto Viejo and Manzanillo were not completed until 1989!) I was surprised that all of the power pole transformers in this area were relatively new, until I read that before 20 years ago, there was no electric service there. There is supposed to be an AM station at 1600 in Puerto Viejo, but they were not on the air Wednesday afternoon.

    The bus ride to San Jose gave me some more insights into radio service in Costa Rica:
    1) The rugged terrain causes FM signal strengths to fluctuate wildly when listening in a vehicle. Distant signals can pop in momentarily and soon vanish, as they are shadowed by hills.
    2) There are large rural "white areas" without any kind of radio service.
    3) FM translator systems are not as expansive as they are in Panama.

    The bus route followed highways 32 and later 36. These highways were in much better repair than the rural roads and comparable to the US highway system (two lanes with an occasional widening to 3 for passing). As we approached Siquirres, some FM signals started to become audible. I would later find out that the stronger ones were local, but a few were from San Jose. I passed one structure that looked like an AM tower (possibly TI-LG 1580 kHz), but I could not receive any AM signals, save for the weak skywave signals that were starting to come in. Later on in the trip, we passed Guapiles, where I heard a local AM station, likely on 1600. They were having some kind of discussion show, and if I remember correctly, the topic was the World Cup soccer game between Costa Rica and the US.

    To be continued....

    The pre-game show to the Costa Rica-US World Cup soccer game and eventually parts of the game were played over the radio on the bus. The radio on the bus was tuned to a FM station on the high side of the dial, which I think was out of San Jose. Geographically, the route that we were taking on highway 36 went around San Jose, on the other side of a ridge of mountains. Thus, the air distance to San Jose was significantly less than what the highway signs stated. The San Jose FM stations that were audible at this point were likely transmitting from an antenna farm located near the Irazu volcano. This antenna farm is located on the highest point in Costa Rica. There is also a Channel 6 television transmitter there.

    Approaching San Jose, various AM and FM signals could be heard, although the close spacing of the FMs--possibly second adjacent in some cases--tended to drive the SRF-42's AFC nuts. Some of the San Jose AM stations were spaced by as little as 20 kHz!

    One of the more unexpected stations on the FM side was an outfit calling itself "Beats 106." They were running a techno and house mix show that at one point made me question what Costa Rican broadcast decency standards might be when the material is in a foreign language. In the mix was either a rap song or a set of samples that said, "You're in Miami, bitch!" and had some other remarks that were pretty degrading towards women, though I can't specifically recall them. I don't remember hearing any of the George Carlin words, though the picket-fencing was causing the signal to be unlistenable at times.

    The World Cup soccer game was being carried both on FM and AM. There was one AM station where a discussion of the game was going on. It goes without saying that World Cup soccer is taken very seriously over there. Programming-wise, many of the AM stations were running religious formats. There were two educational stations (590 and 870) and one oldies station (Radio Libertad 570). I think that I might have also heard some salsa and cumbia sounds on AM.

    Despite the crowding at the low end and the middle of San Jose's AM dial, the dial seemed to stop around 1300. There is a station licensed to 1280 kHz, which I am pretty sure that I heard. There is also one on 1360 kHz, which may have been off the air. The Universidad de Costa Rica radio station on 870 was in AM Stereo, but was not much to write home about. It had a 120 Hz hum in the L-R channel, and it seemed like only some of the sources feeding the board were actually stereo. Thus, one song would have separation but the next one wouldn't. (Note: according the Universidad de Costa Rica website, the 870 AM programming is simulcast on shortwave at 6.105 MHz).

    Radio Libertad had a unique format of pop oldies from the 1950s through the 1980s. Top 40 radio quickly gained popularity in Latin America very shortly after its debut in the US. I was very surprised to hear nobody else running this format. The Radio Libertad format featured a live DJ with requests and dedications. One time that I was listening, unfortunately, the DJ goofed up and played some of the songs twice. To give an idea of what the music mix on this station sounded like, I heard a song that sounded like Danny and the Juniors with Spanish lyrics, some more traditional sounding Spanish ballads, A song with Portugese lyrics (the sound somewhat reminiscent of "The Girl From Ipanema"), some mid 60s rock with Spanish lyrics, "I Just Called To Say I Love You" (announced in Spanish as Llame solo para decirte que te amo), "Yesterday," and "Satisfaction." The last of these I believe to be the best example of a recording that was meant to be heard over AM radio.

    I am starting to regret not having brought a shortwave radio on this trip. In Costa Rica, I saw three funny-looking transmitting sites that did not look like regular AM antenna arrays. At first, I thought that these sites were a relic of an earlier era, but I might have been wrong.

    The first was along highway 32, on the way to Siquirres. There was a sign outside the facility identifying it as some sort of experimental facility. This site had several (I want to say 5) radio towers supporting a mesh of wires that was draped between the towers and sloped to the ground around the outer towers. There were an additional two towers that each supported a large rectangular loop antenna (two sides of the loop ran partway down two of the top guy wires, and the other two sides ran back to the tower). I suspect that this may have been some type of longwave site (the mesh being a large capacitance hat for the transmitting antenna), but I have no clue about what the purpose of this site was or what frequency or frequencies they used.

    In the San Jose area, there were two sites that may have been shortwave facilities. One had four towers arranged in a square with a wire running on the tops of the tower along the edges of the square (i.e. a horizontal loop antenna). Another site had two self-supporting towers with a wire running between them and another wire running down from the midway point (possibly a dipole antenna, if the wire at the midway point was coax).

    To be continued....

    To answer a question that I didn't address directly: the Panamanian and Costa Rican AM facilities seem to be very simple by our standards. The fanciest site that I saw was the two-tower array next to the Bocas del Toro airport, presumably for 660 kHz. I didn't have a good way to determine whether any of the stations reduced power at night, but from the Costa Rican table of stations that I found, my guess is that for the most part these stations operate at the same power levels, day and night. That would explain why the nighttime AM dial in Central America seems to be so cluttered. I think that it is possible that in this part of the world, mediumwave was never intended to be used to provide wide-area coverage; shortwave filled that role until the advent of FM translators.

    San Jose was an interesting place; this city triggered some childhood memories of growing up in Concepcion, Chile, specifically with regards to the ubiquity of bars on windows and metal fences around houses and buildings. In my recollection, in Chile, fences were commonly used to mark one's property line and as a security measure; if well constructed, they were considered to enhance the beauty of a yard. Metal bars on the windows of homes and businesses were usually found in the city, particularly in rough neighborhoods. San Jose took the concept a bit further: metal bars and fences were universally used, regardless of whether the neighborhood was nice or crummy. Razor wire or, in some cases electrified wires, were run along the tops of many of the fences and in some cases below second-story windows. To a visitor, this could make the city seem more dangerous than it is.

    Nonetheless, I found the idiosyncrasies of San Jose architecture to be quite charming. There were many mansions (surrounded by ornate cement and wrought iron fences) that were donated to non-profits or government agencies and thus became museums, hotels, or government offices.

    There is a certain level of simplicity and humility to San Jose, which I thought was well symbolized by the President's house: it is a large single-story home, relatively close to the street, with a small yard. It is next to a vacant lot! When I passed by the President's house on the tour bus, the gate was open, and a policeman was standing guard. A nice black sedan, which I was told was the President's car, was parked just beyond the gate. There were no stretch limousines or anything over-the-top like that.

    Just outside the city of San Jose are rainforests, mountains, and volcanoes. There are several interesting ways to see the rainforests: one is to repel down a cable that has been strung between high points over the forest canopy; the other is to ride an aerial tram over the forest canopy. I tried both. Cable-repelling (marketed as a "canopy tour") is more of a thrill ride than anything else. You get some nice views from the platforms, but when you are repelling down the cable, you are moving too fast to get much of an appreciation for what is around you. It is a good opportunity to yell ¡Pura vida!*

    The nature preserve aerial tram ( http://www.rainforestrams.com/craintro.html ) provided a much more educational experience. The only disappointment was that in the early afternoon, when I went on the tour, most of the animals were hiding. The tour guides recommended visiting the preserve early in the morning, as that is when the animals come out to feed. I saw one sloth and one toucan. I commented that this was the first toucan that I had seen that was not on a cereal box. That is not completely accurate, but that was the first time that I had been in the presence of a wild toucan.

    * This is an expression that Costa Ricans like to use as a greeting or in pleasurable situations. Translated, it means "pure life" or "full of life." One might say ¡Pura vida! while clinking shotglasses, while having a good dinner, while talking about Puerto Rican adventures, etc.

    Thanks for the fascinating look at radio in foreign lands, Alfredo. The reception reports remind me of Mexican radio. And it puts in perspective what it would be like in this country if the F.C.C. had not established a strong set of frequency allocations and assignments. Imagine if every state had its own set of arbitrary rules for frequency and power? It would be chaos in the jungle.

    I wonder whether pre-NARBA, the North American AM radio dial sounded as cluttered at night as it does in Central America. The analogy of each state having its own spectrum regulating association is a good analogy for what little countries all over the world must face in doing frequency allocations. We're used to the notion each of the major countries in North America has some clear channel frequencies reserved for it. If each state were an independent country, imagine how hairy it would get to work out the international treaties so that a station could broadcast with 50kW at night!

    Despite the clutter, the amount of nighttime interference that any one station suffers within the reach of its groundwave is low because the skywave signals aren't that strong. I didn't hear anything as bad as the interference that KKSL used to get from the 1290 in Pendleton, and I certainly didn't hear any really big trainwrecks like what we hear on 1230, 1240, 1340, 1400, 1450, and 1490.

    From what I remember my dad saying many years ago, some of the larger South American countries, such as Brazil, have high powered AM radio stations that can be heard over most of the continent at night. When I lived in Chile, I remember my mom spinning the radio dial one night, and many stations could be heard, with many stations splattering on their neighbors (likely, they were running full-bandwidth audio into their transmitters).

    Speaking of audio, I thought that the San Jose AMs were overall of a better quality than the Panama City AMs. I suspect that neither country has any regulations specifying pre-emphasis curves or requiring any sort of frequency response proofing. Thus, it sounds as though stations may just be arbitrarily EQing the sound to compensate for receiver frequency response characteristics. Overall, it sounds like almost all of the AM stations use very simple processing. For instance, on Radio Libertad (570), the EQ changed from song-to-song ("I Just Called To Say I Love You" sounded bright and punchy, but some of the 60s songs sounded muddy or tinny); the processing sounded like a simple AGC and peak limiter. The audio drive into the transmitter sounded like it was a little on the hot side, with slight distortion occurring on modulation peaks. On the way out of San Jose, I was listening mostly to 570. The signal had pretty good coverage until the bus got high up into the hills; then it started fadind in and out, as the bus made its way between the different peaks in the jagged terrain.

    I have been trying to see if I can pick up the Universidad de Costa Rica station on 6.105 MHz. So far, the most I have been able to hear on that frequency have been some weak, unintelligible murmurs. Has anyone on this board ever DXed any Costa Rican or Panamanian radio stations? Also, does anybody know of any websites of Central American (or other Latin American) DX clubs? They must have DXers over there, and I'm curious as to what those DXers listen to.

    I've been meaning to wrap up this travelogue, as I don't know whether whether interest in this thread is starting to fade.

    On Sunday (June 7), I was on the Tica Bus out of San Jose, headed back to Panama city. This was to be a 16 hour bus ride. I started the trip listening to the Universidad de Costa Rica radio station (870) but felt the need to change the station when they went into a long program on how to select the best pet for one's family. I ended up landing on Radio Libertad 570, with their unique and exciting mix of oldies hits. Exiting the San Jose area, I passed by an AM site that I think might have been Radio Rica 640. The antenna was a single folded unipole tower, and it looked somewhat short for the wavelength. Not finding the programming there too compelling, I flipped back to 570 and listened to it until it was almost gone. After that, I tried listening to some the FM stations, but I got frustrated with the way that their signals popped in and out, and the way that the AFC jumped willy-nilly between all of the closely-spaced stations.

    After I came to terms with the fact that I had entered a rural area of Costa Rica where there were no receivable AM stations and a few fringe FM stations that were frustrating to listen to, I turned off the radio and went about making more progress in my reading of _Murrow_ and of catching up on my sleep. The Costa Rican radio experience changed my mind, to some extent, regarding why AM radios with those awful 3kHz audio bandwidths were once in vogue: they were made with markets like this in mind. Although I was glad that I had the SRF-42 as an AM transmitter diagnostic tool, I wish that I had something with a less hyperactive FM AFC to help in dealing with the close-spaced FM stations. Sometime later, my travel companion gave me a hard time about having an AM/FM radio, boasting how her iPod could hold 1750 songs and play movies and videos from Comedy Central. I said that I could have brought an MP3 player, but if I had, then I would be listening to stuff that was already familiar to me, but what I wanted to do on this trip was to find out what people in that part of the world listened to. I don't know whether she understood or cared for my answer--and it doesn't really matter. Somewhat ironically, the San Jose FM dial had a number of stations that played English-language music.

    Approaching the Panamanian border, around 8 PM, I started to hear some stations. If memory serves me correctly, there were two AMs, both broadcasting network programming, and a handful of FMs. Crossing the border on a bus is a multi-step operation that almost left me stranded. The operation works like this: the bus stops at the Costa Rican border office and lets everybody off. One is supposed to stand in line there to get one's pasport stamped to reflect having exited Costa Rica and to turn in a form about one's travels. Then, one walks to the Panamanian border office, and several things are supposed to happen there: one is supposed to buy a tourist card for $5, one's luggage is inspected, and then one stands in line for a clerk the Panamanian entry window, where one turns in a form about swine flu and has one's passport and tourist card stamped. Unfortunately, I got the order of operations on the Panamanian side screwed up, thereby wasting precious time. To make matters worse, the lady who manned the window where the tourist cards were sold had vanished (she was eventually found, as the bus was almost ready to leave!!)

    After getting back on the bus, I listened to the radio for a bit. In this somewhat rural location, the few formats available were all things that I had heard before, so I opted for going back to sleep, as the bus reading lights didn't work. About 11:30 PM, the bus made a food stop at a travel cafeteria. Cafeteria food is very cheap in Panama: I bought two tortillas (these were corn patties about the size of a small hash brown) and a little beef empanada for a total of 75 cents!

    Approaching the Panama City bus station from Central Panama, I heard an unusual musical style that I would later hear identified as "Montañero." This type of music featured a concertina, percussion, and an electric bass guitar. The rhythm of the music and male Spanish lyrics had a staccato quality to them; interspersed in the male lyrics was a female voice chanting what I assume was some indigenous language. The novelty of Montañero music seemed like something that would wear off very quickly, as many of the songs sounded similar to my ears. After a long cab ride from the bus station, I arrived in Gamboa, where I spent the night. Gamboa is next to the Panama Canal, roughly halfway between the two ports (Panama City and Colon).

    The next day, after a visit to the Panama Canal, I did another spin of the radio dial while my travel companion was doing more tourist-ey things. Gamboa is approximately 25 miles from both Panama City and Colon. I could hear stations from both cities, but the signals were surprisingly weak, even on the AM side, for the relatively short distances involved. What surprised me the most was that Radio Lider from Panama City (which was 550 or 560 AM), was very faint. Radio Lider was probably one of the worst of the Panama City AM stations: they had low modulation levels and badly distorted audio. On this particular day, a Monday afternoon, no less, their automation puked, and they were just playing an endless string of Radio Lider IDs without any music or commercials.

    The next day, I flew back to the US. Although this trip was pretty interesting and certainly a new experience, I was glad to return to Portland. Before ending this travelogue, I have to mention one key difference that I observed between radio over there and in the US. That difference is that with the exception of some of the shows that I heard on the religious stations, there is no syndicated or pre-produced programming over there. Thus, the radio networks and stations over there are completely responsible for producing everything that they air. I think that this may help to explain the poor production values that I heard on some of the smaller market local programs (such as those of Imagen Estereo 97.9) and why many small communities are not able to sustain local radio stations.

    "I don't know whether whether interest in this thread is starting to fade."

    Nope. Getting an education we couldn't get elsewhere.

    Yes! THANKS Indeed ! Great reading.

    Not to change the subject too much, but what is the title of the Edward R Murrow book that you were reading on the trip?

    _Murrow:_His_Life_and_Times_ by A.M. Sperber.

    http://www.amazon.com/Murrow-Times-Communications-Media-Studies/dp/0823218821/ref=sr_1_1?ie=UTF8&s=books&qid=1245280675&sr=8-1

    I bought my copy used at Powell's Books. It is the 1986 printing, which has the same cover photo but the title is set a little bit differently. I also have a video on Murrow, where Sperber is interviewed.

    While in Panama and Costa Rica, I saw some strange looking TV receive antennas. One design that was very common in Bocas del Toro, and to a lesser extent in Costa Rica, was a bi-loop design that I had never seen before. The antenna looked like an infinity symbol. Some of these antennas had what appeared to be wires or springs inside of the loops. Another popular design was the VHF-only fan dipole with a reflector; this was a popular antenna in the US in the 1950s, and one still sees them in some older neighborhoods in this country.
