RE: [Repeater-Builder] Mitrek Interface (PTT Lockup)
Maybe I am a little confused (which is easy, since I have been working out in a steamy garage all day!)... I have done the 12-to-4 jump and nothing, PTT was still locked up. I even did the Pin 1 to Pin 25 on the bottom of the radio and ptt is still locked up.. If this helps, as soon as I unplug the radio from the irlp interface, PTT goes out.. When I plug my Mic out cable into my MIC jack on my sound card, I get nothing but squelch... Does that help any? Thanks.

Remove the 1-25 jumper. Are you using a control head? Unhook the IRLP board completely. Let both pin 13 and 16 float in the breeze separately. Completely unconnected. As I said earlier, pin 13 is PTT and pin 16 switches the receiver between carrier and PL mode. It has nothing to do with the transmitter. The two should never be tied together (unless both happen to be grounded at the same time). Power up everything and the radio should be in receive. If not, find that problem. Ground only pin 13. It should go into transmit. Ungrounded, it should go to receive. If not, then there is another problem. Once you have it that far, then write back. If you feel this is more appropriate to handle off list, that's fine. Mike WA6ILQ Yahoo!

How about continuity to ground on the IRLP's PTT line when NOT connected to the Mitrek. Maybe the switching transistor on the IRLP board is bad?
