I keep trying to join that forum, and it must be abandoned by the admins. I'll have to check and see whether I'm already on software carrier detect, I may be. The advice to use 9600 line I will take. I was trying to reserve it for a soundcard connection, but I may just have to come up with a switch box to switch between TNC and soundcard interface later on. It's a work in progress. I was just trying to get the TNC going right now rather than my usual procrastination planning process. Mostly all I'm asking here is if anyone is seeing similar behavior in their FTM-300 RX1200 line since I can't seem to get an answer from Yaesu and I can't even join the 300 group. Oh I forgot to mention also that the actual speaker jack in the back does NOT seem to have the same behavior as the RX1200 line. Unless I messed up my scope settings the speaker line is the same level (not counting the actual received signal level) whether the squelch is left turned all the way down or not on a received signal. No voltage spike or drop on squelch opening and closing.?
