Found this 1978 article interesting. Two radio stations filed a joint complaint over a 16 year old kids part 15 station. Ver the course of three years his parents had funneled about $20,000 into the station.. Ive not been able to find out what ever became of the issue. Also interesting is the article reports the FCC refers to such stations as "Peewees", though I've never come across the FCC ever making such reference.  |

They were on AM but back then AM was still king of the airwaves. Wonder what transmitter was available back then? I think Heathkit had something but you notice there is a distance stated of 300ft. If a legal AM transmitter at 100mW into the final amp as per part 15.219 was set up right outside it could go a mile or more and it would be legal. Maybe this kid did his homework and knew the rules and the 2 complaining stations didn't as they mentioned distance?
$20,000! a very expensive part 15 station.
I say more power to the kid!

Well in the article he did mention he began with a $20 Heathkit and an array of coat hangers in the attic for an antenna, but over 3 years and $20k of his parents money it had graduated into a full fledged station (so to speak).. It also says the signal can b we heard up to a mile and a half sometimes more.. There's no mention of the transmitter used, but considering they spared no expense, I presume it to have been a Audio-Sine model because they were the Hamilton Rangemasters of their time and the ONLY part 15 transmitters the NPS used after 1974 on which was when their production began, originally as a talking billboard!

To clarify, The Audio-Sine came out in 1974 as a talking billboard but that idea didn't take off (it would later), but it did catch the NPS attention and they became Audio-Sine's primary customer for the next 20 years, they later went on to become primary supplier of 10w TIS systems as well.
The Audio-Sine part 15 transmitter was priced in the $1200 range in the mid 1970s.
