Hi Sam, Yes set up can be tricky. Yes I think there is an error in teh digram in the manual, as you say, no point in connecting p12 and 13. I'll fix that.
Couple of ideas on the 817: 1/ Check your pin out to the 817 is correct by looking for +5V between (3) to GND(7). 2/ Try triggering PTT on the 817 by manually shorting 6 and 7 3/ If that works try connecting the SM1000 PTT GND (12 or 13) to 10 or 11. All the grounds are isolated by default, so you need to explicitly connect them. 4/ Mic GND (4) should be isolated from SPKR Ground and connected directly to 11. 5/ Should SPKR (1) be connected to 16?
