Let’s now focus upon AM610, an AM Carrier-Current station, where we couple into the power lines, as permissible via FCC Part 15 Rules. https://www.hobbybroadcaster.net/resources/carrier-current-AM-broadcasting.php You, may remember Carrier-Current Broadcasting from college radio. There are still a couple of stations doing so, like WPPJ in Pittsburgh, PA. https://wppjradio.com/ Our carrier-current experiment started in the mid-1980’s, where I coupled a cheap AM radio’s local-oscillator to the Neutral of our house wiring and discovered that the signal could be heard over 300ft away, down the power lines. That project went up in smoke, literally! And, scrapped until April 1991, where we bought the Panaxis Productions, from Ernest Wilson, the AM-100, 100 milliwatts AM transmitter kit. (Still have...) Coupling to the power lines was crude, at best, until I was able to obtain, first a JOY Mine-shaft COMM’s coupler, (Sent to Boomer of WAG AM690.), then a Radio Systems, CP-15 Coupler, (Using that presently.), and an LPB, Inc., T-8. Our transmitter now is an older PLL.gr 0-20 watt transmitter kit, bought an assembled in 2015. AM610 is using the James R. Cunningham method of Neutral-Injecting, with a ½ watt carrier. Our signal, today, only travels +/- ¼ mile, due to newly installed power transformers in our neighborhood. So, AM610 is pretty much a glorified STL, (Studio to Transmitter Link), to feed AM1620’s audio. Next, plan to cover Auxiliary Station 49.870MHz FM.
