I forgot to add that the 30 series uses a BTL audio amp.The speaker low is not to be connected to ground,or the amp will blow.

OK to hok up a TNC then can you confirm my thoughts on the pin outs.
TNC - tk-x30
PTT - 8 PTT
GND - 2 Mic Gound
Audio Out - 5 mic high
Audio in - 4 detector audio out
hummm ok just casue I'm new at this, is there anyway to get a line level audio in and out to by pass the mic curcuit so that I can maybe get 9600 bps working.
thnaks
