I have been using RemoteRig RRC-1258 MKII successfully since 2016. My radio is Icom IC-7100. I have had success with CW and use a straight key. The key is plugged into the jack on rear of control head. Recently when I press the key the radio begins transmitting erratically and I have no control. This happens randomly. At times it will work fine for a short period of time and then malfunction. I cannot get it to work on 40 meters at any time, but at times will work for few minutes on 10, 15 and 20. I thought this might be a power supply issue but have substituted power supply and problem persists. This has been going on for about a year. If anyone else is having this problem I would love to hear from them.
