Hello Skip:
Great Web Site, good seeing ya out here. Carry on............... Jay in the Mojave Skipp is still around wrote: The receivers were a rather broad tuned (front end) circuit, only the transmitter was crystal controlled. Some of the receiver circuits were even regnerative type layouts. With minimal front end selection, you pretty much hear anything for quite a spectral distance on each side of the tune peak. cheers skipp www.radiowrench.com/sonic remember the old sonic server? well it's moved to the above url.

I : think it's rather a neat feature, to be able to monitor all 40 : channels at the same time, like my small 100mw walkie talkies seemed : to receive all 23 back then. Just a thought! Thanks! : -Stephen |
