[RTTY] FSK interface for TS940

[NCB02761@nifty.ne.jp (7L4IOU)]

Hi Paolo 

I am using  MMTTY with TS-930 and IC-756Pro,  
 and having a same problem with TS-930. 

I have two solutions, both worked well. 

1. Insert an Inverter (one step TR switch) to TS-930 side.
 
2. Drive a small reed relay, and keying FSK by contact. 

Finally, I selected method 1.
