<pre style="white-space: pre-wrap; word-wrap:break-word; font-family: sans-serif; margin-top: 0px">Thank you for all the suggestions thus far.<br /><br />I'm using an ICOM IC-A110 VHF radio. I was able to find some<br />schematics/block diagrams in the service manual here:<br /><br /><a href="http://elektrotanya.com/icom_ic-a110,_a110e_service_manual.pdf/download.html">http://elektrotanya.com/icom_ic-a110,_a110e_service_manual.pdf/download.html</a><br /><br />This is my first time trying to dig through a radio and find a COR. I'm not<br />sure either where to get a discriminator audio signal either.<br /><br />Josh<br /><br />-----Original Message-----<br />From: Bryan D.

It<br /></blockquote>turns out my COR signal might not necessarily be the best COR signal. It<br />looks like the signal goes high on BOTH RX and TX. This is probably causing<br />asterisk to think its receiving when its sending getting into a nice<br />infinite loop.<br /><br /><br />Then you don't have a true COR signal. What radio (make/model) are you<br />using? Can you get discriminator audio?? If so, you can use dsp to<br />derive COR; otherwise, you need to look elsewhere. Sounds like you're<br />too far down the circuit.<br /><br /><blockquote class="gmail_quote" style="margin: 0pt 0pt 1ex 0.8ex; border-left: 1px solid #729fcf; padding-left: 1ex;">I'm going to try an AND gate with the PTT so that PTT has to be high (i.e.<br /></blockquote>NOT TX) and speaker mute (my COR) has to be high for a true COR output on<br />RX.<br /><br /><br />Sounds
complicated; I'm thinking some quality time with the schematic<br />will provide an answer that is more agreeable and doesn't require<br />building logic circuits. In all the machines I've built the most<br />complex interface has been a pullup resistor on the DB25 connector. And<br />that's for everything from a micor to wouxun HTs to maxtracs and gtx's<br />and systel, and ALinco radio-based repeaters. And throw in a couple GE<br />rigs (Mastr-IIs) along the way. Heck, I even interfaced a TR-33C as a<br />receiver in a pinch.<br /><br /><blockquote class="gmail_quote" style="margin: 0pt 0pt 1ex 0.8ex; border-left: 1px solid #729fcf; padding-left: 1ex;">In the meantime I tried carrierfrom=vox but it didn't really seem to work.<br /></blockquote>Anybody get this working properly?<br /><br /><br />As our Maximum Leader Jim says: "Friends don't let friends use VOX".<br />Not a way to do it; and is an artifact of development.<br /><br />BB WB0YLE<br />Allstar 27294, 27295, 27673,
