In the early 80s, we had a neighbor complain that we were bleeding over onto his intercom system. The first hint of this was an anonymous (no return address) letter sent to our house complaining about our radio, but too vague for us to figure out who sent it or what the problem might be. We were running a stock, untouched, barefoot TRC 448 mobile with a Turner +3 base mic hooked up a Radio Shack .64 wave omni. It was 100% legal with no kicker ever, so I didn't give the letter much thought. Sure enough, we got a visit one day a few months later from "Uncle Charlie".
The gentlemen were nice enough. I was about 18 or 19 and studying for my novice license at the time, so I was probably a little better versed than the good buddies of the day who bought their Kraco CB right after watching Convoy. I proudly showed them my rig, which I had quite neatly and professionally installed: tie downs, spacers, silicone seals, water-tight coax-to-antenna connector, plastic tubing covering my exposed RG-8, etc. I had even replaced all of the hardware on my .64 with stainless steel. Damn, my set up looked good! I think they were shocked that a teenager had put so much thought into setting up a CB.
My TRC 448, which they did ask to see, had never been opened. That was pretty obvious to anyone looking. I also volunteered that I had a TRC 451 in the sailboat out back, and explained that the whole point of our set up was to be able to communicate from house to boat by two way radio.
They got it. The gentlemen asked few questions, asked to see our station license (I always used our call sign), accepted my explanations and did not even bother to test my radios. They obviously had been listening to my transmissions because they threw in some nice compliments about the sound quality of our station and my radio etiquette.
To their credit, I think: (1) they got a complaint, (2) did what they had to do to check it out, (3) concluded it was b.s. and (4) were nice enough about the whole thing. They also wished me luck on the novice exam.
