Phil Green Posted March 2, 2013 Share Posted March 2, 2013 This is a simple 35mhz FM Single-Channel tone set, using an approved RF module, with a dual-conversion superhet relayless receiver driving an Elmic escapement, and not a microchip in sight. Well, alright, the transmitted tone is generated by an IC, but honestly, thats all it does, just generates a 1khz audio tone, keyed on & off with the button. Theres absolutely no microprocessor emulation or anything like. I'll put more detail on singlechannel.co.uk soon. **LINK** The completed project works just great, heres a video of the set in operation: Cheers Phil Edited By Phil Green on 02/03/2013 23:23:11 Quote Link to comment Share on other sites More sharing options...
