So the RC1261H only serves to manage one thing ... I was wondering why I have been using the RRC1258 MKII pair with Icom 7100 radio for a long time and it works perfectly, I manage my Expert SPE1.3k FA with a simple Ethernet / Com RS232 converter made via web and IP port of my ddns with Expert software but I thought that I would have simplified everything by managing Radio, Amplifier and Antenna with the purchase of the RC-1216H.
