Hi Doug, Yeah sometimes it can be cluster to get external generated CTCSS Tones inserted back into the GTX-900 radio transmit audio. I'd first check the rear accessory jack pin functions to see if and what any of the available "ports" can do to the transmit audio.
The Motorhead (Motorola) mic-audio low frequency filters are probably so over engineered that blowing tones with the repeater audio isn't even worth trying/practical. Otherwise it's some type of hard wired connection/mod into the proper section of the radio internals. I asked him why he had the TP-3200 in the first place... "it was donation" so the price was right. Unless one really needs the mult-tone CTCSS encoding... program the GTX-900 radio up with the master tone frequency and use the TP-3200 to decode any & all the rx tones just to get on with life. cheers, skipp ps: C'ya at Dayton this year. > Doug Bade <[EMAIL PROTECTED]> wrote: > Skipp; > The specific controller he is using and was asking about is > a Comm Spec ( TP3200 as I recall ) commercial repeater controller. > My comments were directed towards commercial not amateur > controllers...Commercial repeater controllers designed for multi-tone > community repeater applications etc...do in fact by necessity need to > strip and re-insert tones.. but your comment is quite true on the > average low/lower end amateur controller, most do not have sufficient > filtering to completely remove ctcss and a portion sneaks through > anyhow.. unless you add your own filter aka ts-64 as you point out... > > Doug > KD8B
