    I will make it my New Year's resolution to use some less-used technical terms, such as:

    PAL = Phase Alternating Line, an analog color video system developed in Germany that became common in many countries that formerly used monochrome systems with a 50 Hz refresh rate

    IBOC = In-Band On-Channel, a generic term for digital broadcasting systems that use the existing AM and FM broadcast bands.
    MW = Medium Wave, the European name for what we call the AM band or the Standard Broadcast band. The term MW differentiates this band from the shortwave and longwave broadcast bands, which also use amplitude modulation.
    XTAL = Crystal
    XMTR = Transmitter
    XFORMER = Transformer
    XMAS = Ho, ho, ho!

    SECAM was definitely "Entirely Contrary to American Methods," as well as those used everywhere else in Europe. The original French SECAM used positive video modulation as well as AM sound. This made foreign television broadcasts unwatchable on French TVs. I wonder whether the French did this on purpose.

    The use of positive video modulation makes it impossible to implement effective AGC because the sync* tips of the video signal end up corresponding to zero RF power. French TVs and British 405 line TVs that had AGC had to respond to the average RF envelope level. This meant that dark scenes could not be displayed accurately because the receiver's AGC would artificially raise their brightness.

    sync or SYNC = synchronization

    Good catch, Mr. Eye. I did generate the list mostly from memory, and subbing "standards" for "services" in NTSC is a mistake I have made often. Maybe Dan can fix it, although it's not that crucial.

    The reason why "tint" moves around so much in analog television broadcasting is mostly caused by varying levels of video, not so much the drifting of the pedestal a few points (black level, basically) but the resultant change in the distance from black to white caused by changing video levels.

    Remember that the time honored scope pattern of NTSC video is actually upside down, that is the tip of sync which displays downward on a Tek waveform monitor is actually positive, and no video (black) which shows on the monitor as a flat line 7.5 IRE above the baseline is actually max power, Analog TV transmitters groan and moan when they are held in black for very long, and all the current meters hit their peak, sometimes sagging the plate voltage in the final PA. Anyway, not to digress too far, the distance between black (no video) and white (max video) is what effects color. The chroma subcarrier is comprised of the difference between blue and luma (luminance or brightness) and red and luma. These difference signals change with the varying video level and without correction can effect the perceived color. Usually, in a produced video the entire length of video can be color balanced before it ever gets broadcast, minimizing the tonal changes from dark scenes to bright scenes that make someone's tie or shirt look different from scene to scene.

    Anyway, it's harder to manage with live TV. At the transmitter back in analog days, there were processors that constantly monitored video level, sync level, chroma level, chroma phase, set up (pedestal) and a few other parameters and adjust them using AGC (automatic gain control). By the time, though, that Tektronix came out with the 1440 Video corrector NTSC already had been ordained with its moniker. Before auto correction, transmitter engineers used to have man the transmitter site and ride the gain especially when going from local into network or vice versa and also in live programs where the shader (the guy in master control riding the camera video levels) was not keeping up with the director and letting takes happen with improper levels. But even with a good shader and a Tek 1440, sometimes the commercials would have so much video information (usually caused by graphics and text being superimposed over other video) could bring the systems right to the edge.

    Some additions:
    AC = alternating current sometimes "adult contemporary"
    DC = direct current sometimes a publisher of comics
    AGC = automatic gain control
    PA = power amplifier sometimes "public address" system of amplifiers and speakers
    V = voltage in volts
    I = current in amps
    P = Power in watts
    Ω = Resistance in Ohms
    Z = impedance (= DC resistance plus AC resistance)
    π = pi, the ratio of a circle's circumference to its diameter, and is approximately equal to 3.14159
    Ø = the null set, or undefined, or the sum and total of your political nemesis's knowledge . . . depending on which side of the board it appears.

    SECAM = System Entirely Contrary to the American Method
    PAL = Perfection At Last, Pay Again for Luxury, Pay Another Licence

    I recall that as late as 1988 or so, some television stations would occasionally overmodulate the video, causing a very distinctive 60 Hz buzz in the audio. I wondered, "don't these guys have a peak limiter, like radio stations do?"

    The actual name for it is "intercarrier buzz". It is an inherent defect in NTSC and PAL analog transmissions. The video signal is transmitted "upside down"(see my earlier post about waveform monitoring) and because of that a black signal causes full modulation and a white signal or bright colors causes very little modulation on the video carrier.The minimum video carrier modulation is around 12.5% and that corresponds to 100 IRE peak white before the video signal is transmitted. As long as the composite video signal at the tv station stays at or below 100 IRE you usually will not get intercarrier buzz in your tv set. Unfortunately bright colors and characters often go past 100 IRE and reduce that minimum 12.5% carrier modulation even lower and that cross-modulates the audio signal causing the buzz. The term for that is called ICPM (incidental carrier phase modulation) and can be considered IMD.

    So basically when the video carrier between the sync tip and peak white (remember the video signal is inverted during transmission) drops below 12.5% you are going to get the buzz and there is nothing you can do about it. It just so happens that some sets are better at rejecting the buzz than others.The buzz is virtually non existant in good quality modern analog sets because of the use of SAW filters in the video IF stages.The problem is more pronounced on vintage sets with transformer coupled IF's. Sometimes you may minimize it by doing a precise IF alignment. In some sets you can never get rid of the problem because of an inferior design.You can tweak all you want and never get rid of it.

    "The actual name for it is "intercarrier buzz". It is an inherent defect in NTSC"

    I have to disagree here, I don't think that it is an inherent defect in NTSC, but instead related to poor receiver video IF/AGC design. The classic RCA 630 TV did not exhibit intercarrier buzz.

    I recall that at Portland Cable Access, producers were cautioned, "keep the video levels below 100 IRE or you WILL get buzz!"

    In one of my old Motorola datasheet books, there is an advanced IF/detector IC where they use a synchronous detector to recover the video with a minimum of distortion. The sophisticated (for the time) trick that they did was that an additional detector, driven at 90 degrees out of phase from the main one, was used to recover the sound carriers. The output of this detector would not have contained the low frequency of the video signal that are transmitted double-sideband. If memory serves me correctly, the reason that Motorola went to all this trouble was that they wanted to create a universal TV IF/demodulator chip that could work with French/Belgian SECAM (AM sound) and with the German Zweiton system (multiple FM carriers). There was actually an AM sound detector included for French market applications.

    KZME is a licensed operation that is currently off the air. They had renewed their silent STA but that is now expired as well. I don't see any further applications to remain silent or anything else. Another company has recently showed interest in taking over the facilities but nothing has been filed yet with the FCC. KWLZ is waiting for KXXO Olympia to finish construction before they can go on the air. Both stations are on basically the same time schedule. KNRQ notified the FCC that they couldn't complete construction at the requested site, before their construction permit expires. They submitted a new application to transmit from the Stonehenge Tower, as a full Class C1, virtually the same signal as KWJJ and KPDQ. They suggested that they would complete construction within a few months of being granted the CP. KYTE, from what I understand, is waiting for a buyer of their CP.

    Here is its TEMPORARY URL:

    http://reboot.fcc.gov/spectrumdashboard/searchSpectrum.seam

    The entire FCC website is in transition. Your old links for AM, FM and TV queries should still work as should any links you've saved for ARS, ULS, etc. That may not last for much longer, especially if the URL you are using as a bookmark has the word "transition" or "reboot" in it.

    The new homepage http://www.fcc.gov/ and the old homepage http://transition.fcc.gov/ aren't the best for getting to, for example, a Query. If you want a good place to start for the purposes of the broadcasting data and developments, conversions and developments use the Audio Division home page at http://www.fcc.gov/encyclopedia/audio-division-media-bureau and scroll down to "Most requested information."

    It is correct that the translator cannot originate programming, however this wouldn't be the case.

    Legally, right now, 107.1 FM (K296FT) is a translator for KQAC HD2 not KZME. There is no reason why this relationship couldn't continue, even if MetroEast sells the KZME license. Heck, if MetroEast has a sweet agreement with All Classical they could make some cash selling their license without losing any service.

    So the *official* id for 107.1 is K296FD (perhaps delivered by FSK) and the *official* id for KQAC-HD2 is "KQAC-HD2", the "KZME" id could cease to exist if they sell the license. They could brand as "KZME-107.1" perhaps, but another station *could* get the call letters and possibly issue a C&D order?

    ----------Harris Broadcast And Geo-Broadcast Offer Solution To Boost FM Radio Signal Coverage----------

    HARRIS BROADCAST and GEO-BROADCAST SOLUTIONS are touting a solution based on GBS' ZoneCasting strategy that will allow radio broadcasters to maximize market-wide signal penetration -- even as the industry awaits FCC approval for ZoneCasting.

    The MaxxCasting solution uses a network topology similar to the ZoneCasting architecture for targeted, over-the-air radio broadcasting, but instead focuses on simulcasting content to improve coverage. It can be deployed today under existing regulations, expanding market coverage in a more sensible and effective way than traditional signal booster technologies.

    "We often hear from broadcasters looking to take advantage of this network topology as our ZoneCasting petition to deliver targeted content moves through FCC approval," said GEO-BROADCAST SYSTEMS CEO PETER HANDY. "The FCC rules currently allow FM stations to deploy boosters to fill in signal coverage gaps, broadcasting identical content on every booster. We have discovered that adding boosters to simulcast across the typical ZoneCasting topology can help broadcasters improve coverage. And the ability to reach more listeners opens new revenue opportunities through advertising."

    ----------------------------------Google Files With FCC To Test 'Radio Station'----------------------------------

    Does GOOGLE want to get into radio? The company has filed a FCC form 442, an "application for new or modified radio station under part 5 of FCC rules - experimental radio service (other than broadcast)."

    DIGITAL TRENDS reports the station would operate "in a two-mile radius surrounding its HQ in MOUNTAIN VIEW, CA. The test network will run somewhere in the 2524MHz and 2625MHz spectrum, and is not only experimental in nature, but far from consumer-oriented. The spectrum being tested is inaccessible by almost all current consumer electronics, including iPHONES and ANDROID devices, meaning it will be years before you see gadgets use this."

    So, don't expect "GOOGLE RADIO" to come from this.

    However, DIGITAL TRENDS notes, "what's special about this band of spectrum is that it's very effective with high-density locations, which makes it very efficient for rolling out wireless access in big cities, and potentially even a successor to current wireless standards."

    I did a street view of the transmitter location in the above construction permit, and I see that it is in the middle of a residential neighborhood. I wonder, is the new KRRC really going to put its transmitter here, or is this just some legal manipulation to keep the license active. (Or, is it possible that KRRC will broadcast from here, while the license is held by Common Frequency, until somebody buys the license from them?)

    8 W ERP is in compliance with their Class D status. Their original application called for 55? watts and as I said in the other thread, a Class D can not do that and upgrading to a Class A can not be done any closer than Brightwood.

    Other than the fact that this keeps the license alive, the coverage area doesn't seem all that appealing for anyone other than, perhaps, the Hawthorne Business Association.

    It seems to me that they either have to build this in three days or hope that all the Reed College equipment is still in place, so they can broadcast from there temporarily. It looks like they've got at least a few months before KNRQ pushes them aside.

    Please correct me if I am wrong: In order for the KRRC license to not be canceled, they (Common Frequency) need to prove that they broadcast from the house on SE 55th Ave. (see jr_tech's link) before 12:00 AM this Sunday.

    @semoochie...
    Since they appear to hold a valid license to operate on 97.9 from the Reed campus, are you suggesting that they could operate from the old facility temporarily (since KNRK has not moved yet), to buy some time to build the 91.1 facility?

    Alfredo is correct.

    Once they initiate a broadcast from the amended location, file an application for license to cover and have that accepted, they can file for an STA. Then they (Common Ground) can sell it all to Metro who can drop their Brightwood plans and operate the new 91.1 from, more than likely, an amended location limited only by its class D status and the need for its 60 dBu to intersect the old 97.9 60 dBu. Even though the 107.1 translator has a better coverage area than 91.1, there does not seem to be a rule blocking that since it is non commercial.

    I can't fathom any other scenario that makes sense.

    It would really be interesting if the scenario described by Andy is indeed the path by which 91.1 orchestrates a move out of Brightwood. Stay tuned!

    It's a tenuous plan, at best. Class D licenses, as we have just seen, can be bumped by any change in the primary service station's landscape. Being a secondary service they also can be made to go silent if they cause any interference that can not be remedied. They will not get bumped by the Community Radio Act or the subsequent granting of new translators coming on after the LPFM window is executed and resolved, but the commercial station layout has been in a constant state of juggling and the downshot is if KRRC loses its ability to broadcast for any reason, they can not continue to feed the translator without changing back to the scenario they now have, assuming that could be done. Meanwhile, there is the money thing. Operating the Class D at Reed was cheap. Now that it is not on campus and has nothing to do with Reed, someone has to house the transmitter and that means rent, insurance, power bill, etc. Add that to the cost of maintaining the translator on Stonehenge, which isn't cheap, and you can see that if Metro buys the Class D, they will see a near doubling in overhead. Just sayin'.

    It would be interesting to find out who owns the house... perhaps it would be a "rent free" situation. The power bill for a 8 watt transmitter and support gear is not likely very high either.

    I'm pretty sure that the current location, assuming the sale to Metro did happen, is just temporary. At any future site, the cost of electricity would be the smaller of all the costs. Still, we're talking about adding costs for equipment not only to transmit but to deliver the signal to the transmitter site, required monitoring equipment, etc. it's four figures, easily. Not even counting insurance. Non profits are mostly running on tight budgets. That's one of the reasons they dragged their feet on Brightwood (in addition to the access to the original proposed site).

    A bare bones budget for low power usually runs about 10k, application included. Can it be done for less? Sure. But not much.

    But they (assuming Metro) are presently delivering the audio to KQAC to transmit on 89.9 HD-2 to feed 107.1. I suspect that KQAC is not providing the HD-2 stream as a free service, so perhaps there would be some cost offsets provided by using the "KRRC facility".
