Your are right about the tk-760 being only carrier squelch without mods. I did one of these a few years back and came up with a mod... but I'll have to look and see if I wrote it down. Folks should note the difference between the tk-760 and the tk-760g model... the "g" version being a different animal.
To the many folks who emailed me about the previously mentioned (by me) book... it is a collection of notes, mods and sorted out horror stories I've written down as I trudged my way through years of two way radio work. As people request info I do scan and share a lot of it via the sonic and repeater builder web pages. Please check those pages first for a lot of great information already on the net. cheers, s. > Peter, > In addition to its very limited heat sink area due to its > compact size, the TK-760 has one deficiency that limits its > usefulness as a receiver in a repeater system: The COS > signal that is available with the KCT-19 accessory cable > is carrier only; the radio has no signal that indicates > when a carrier with the proper CTCSS or CDCSS tone is received. > If you plan to run your repeater with carrier squelch only, > this will not be a problem. > 73, Eric Lemmon WB6FLY
