    This case reminds me a bit of one that happened about ten years ago, when a man was house-sitting for a neighbor and a burglar broke in. The man called 911 to report that a burglary was in progress and told the dispatcher “you better come here quick.” The dispatcher desperately and unsuccessfully tried to talk the man out of taking the law into his own hands. The man fatally shot the burglar in the back.

    At the risk of sounding either extremely callous or of stating what might be considered extremely obvious, I think that there is an important salient point in these tragedies–true law-abiding citizens allow the police to handle burglaries and “suspicious” looking people. The police know the law; people looking to make “citizens’ arrests” or to play hero most likely have no concept of the legal boundaries to what they can do. This is why we fund police departments with the taxes that we pay.

    I tried out one of the Kiwi online radios yesterday (from a link posted previously on this thread), and I was left wondering, what is the intended purpose of the IQ feature? I know what the feature is doing (it is using two product detectors, driven 90 degrees out of phase and routing the output from one detector to the left channel and the other to the right). However, the locally-generated carrier is free-running, unlike that in the synchronous-AM mode.

    I remember KZME, but I think that Wikipedia incorrectly states that KZME broadcast on 91.1 MHz. In my recollection, KZME was carried on the 107.1 MHz translator, but this translator received its audio from a KQAC HD subchannel. That meshes with the above statement of the 91.1 MHz construction permit never being built.

    If the 91.1 construction permit on Mount Hood occurs, is that the end of KXRY?

    YouTube has been in existence for about 15 years, yet TV is still with us.

    In my recollection, somebody on this board stated that today, many DTV multiplexes dynamically assign the throughput allocated to each of the virtual channels. Thus, your answers would be ballpark figures, rather than exact numbers.

    Lamentablemente, estamos hablando de emisoras en el amplitud modulada que son invisibles. No mencionamos 1330 kHz y de esa manera la hacemos desaparecer.

    As of a few weeks ago, KOMO has dropped The Jim Bohannon Show. The midnight hour now is now a rerun of the previous weekend’s Perspective. Perhaps, this is a signal of the beginning of the end.

    The narrative behind Trump having to start his own social media company is designed for the Dale Gribble segment of our society. These are the people who earnestly believe the conspiracy theories. They are easily duped into forgetting that social media companies own all of their equipment and intellectual property. The users are “guests” on these platforms. Facebook, Twitter, or even PDXRadio reserve the rights to delete posts or user accounts for any reason.

    That link has a lyric that expresses my sentiments about the threads that IGGM has started.

    I may have sporadically heard 890 KBBI (Homer, AK) a few nights ago, although I was not able to hear an ID. The dominant station on the frequency was running Coast-to-Coast AM. I turned my loop antenna to null that out, and the dominant station was one playing country music. I carefully nulled that one out, and I was hearing a mish-mash of stations. There was sideband splash from the 880 kHz station in Dallas, OR. Occasionally, I heard a woman’s voice speaking with a slow cadence.

    The recent rainfall must have improved the efficiency of the WQWS230 ground system. From Cornelius Pass Rd. in Hillsboro (near the Harvey statue), 1610 was stopping scan on my car radio. 1640 was having trouble doing the same.

    I will start with a little story. In February of 2001, the 6.8 magnitude Nisqually earthquake cracked one of the base insulators on one of the towers at the 1330/1640 site.

    I took a job as a board operator for Crawford at the end of 2003. It had been assessed that the insulator had to be replaced, but no replacements were available. The engineer had recently decided that converting the affected tower to shunt-feed was the only option.

    Early designs of the antenna skirt (the wires running to the top of the mast) resulted in high RF voltages that made the system prone to arcing. This might have been because the diplexed tower is very close to 1/2 wavelength at 1640 kHz.

    During the summer of 2004, KKPZ had an STA to operate at 1 kW while the skirt was being modified. In my recollection, 1330 was transmitting at this power level using one of the remaining two towers. I do not recall whether 1640 had to sign off during this time or whether it stayed on the air using one of the unaffected towers.

    Returning to the recent past, KKPZ was briefly back on the air, simulcasting a Crawford station from Colorado. When I heard that, I assumed that the purpose was to allow a potential buyer to assess the signal’s coverage. However, I can see how being forced to make the station 1kW non-directional (if re-creating the three-tower array in a slightly different part of town is not feasible) would likely make this a non-starter.

    Oh! Wait! I know; build a three-tower 1330 kHz array and strike up a deal with Bustos to diplex 1150 into it. The tower rent could then offset some of the construction and operating costs. (This entire idea is tongue-in-cheek.)

    The Forest Grove 1570 station used the very apropos selection “Eve of Destruction” when it left the air for the last time. It seems that this, along with a cavalcade of other area stations, were unsuccessful in luring listeners away from KISN.

    Did you get it [the radio with the 940/1410 birdie] locally, around here?

    Yes, I did. Although I don’t know its history, I find it conceivable that the IF was re-adjusted to avoid reception problems on KISN.

    Although the circuit board is accessible by opening the back cover, it is in an awkward position. When I have the time, I would like to re-align the front end because tracking is poor at the low end of the band, severely hurting sensitivity. If I could fully re-align this thing, I would set the IF for either 450 or 460 kHz so that the birdies don’t land on local stations. The radio is like the one shown in this video: https://www.youtube.com/watch?v=ztE8cc4vjb8

    I have a 1960s transistor radio with a squeal on 1410 kHz. This puzzled me for a long time. Then I came up with the hypothesis that this radio used something other than 455 kHz for the IF or it was re-tuned. Voila! I found another squeal at 940 kHz. 470 kHz * 2 = 940 kHz. 470 kHz * 3 = 1410 kHz.
