I'm trying to set up my PiRLP with a Kenwood TK-790 VHF transceiver. These transceivers have a DB-25 connector that has everything you would ever need to connect devises like the PiRLP (headsets, horn relays, etc.). Here is what I've got so far:
PiRLP Pin Kenwood TK-790
1 - No Connection
2 - PTT OUT ???
3 - Aux 1 Out 2 AI1
4 - Aux 2 Out 3 AI2
5 - Aux 3 Out 4 AI3
6 - Ground 18 Earth
7 - COS In 23 Squelch Signal output
8 - Audio In from RX 17 RX audio signal output
9 - Audio Out to TX 13 MIC/data signal input
Does anyone have experience or ideas about this? In particular the PPT OUT from the PiRLP and the Audio Out to TX from the PiRLP? I think the rest of the pinout is correct.
I know that there will probably be some programming changes like activating the external ptt, etc.
Any ideas?
Thanks,
Larry
