I just got a IC-7100 and now working with 1258 RRC.
I connect my bencher keyer to IC-7100 panel elec key port, it works well, that's mean, in IC-7100 situation, only one 8-pins cable need in radio-RRC.
Is that mean: not need connect keyer to control-RRC PAD port, and not need connect a 3.5 cable from radio-RRC PAD port to radio keyer port?
