*Preliminary details*

An Icom PMR set that seems good for 1200bd Packet - 9600 testing to follow.

Short version:

• OPC-617 cable gives you a DB9 data port
• You need to enable external PTT on the cable through the programming software
• You need to bridge solder pad F on the main board to enable data input through the cable
• I briefly flicked the Ninos to 9600 and I got the test sequences going, dummy load to antenna, but I need to spend more time on this.
