I had one of the Sonar FM radios that I bought for $20 already crystalled up on 29.6 MHz in about 1985. I ran if for a base station for a couple years, the squelch action was not the best.
Eventually, I upgraded to a Mocom 70 base! ------ Original Message ------ Received: Sat, 17 Jan 2009 11:21:55 AM PST From: [email protected] To: [email protected] Subject: Re: [Repeater-Builder] Re: OT: Radios and Coms in TV and Movies > Hello Group, > > I have a couple of the "Silver Grill" E.F. Johnson "Business Band" tube type radios from the 60's. They are AM, and about 8 watts out. They are a "Twin" to the CB set Johnson produced around the same time. Also don't forget about "Sonar" brand. They produced a low band business transciever (AM) with matching power amplifier. I am happy there is still an interest in the preservation of these "Boat Anchors" When they are gone.....they are gone forever! They do bring a smile to many folks, and that's what counts. > > I don't know what ever populated the "part 15" 49 mHz. band, after the cordless phones changed frequency.
