I am installing a set RRC-1258 MKII to control an ICOM 706MkIIg. I have followed the instruction with the splitting the separation cable etc. I can turn on the radio and audio as well as all controls seem to work. However, the CW is not working. is it necessary to connect the Radio-RRC PAD output to the radio key input (see manual page 94) or should it be sufficient with just the separation cable?
