Alan, I've worked with a large local PV installer to solve RFI problems, and I can vouch for the fact that it can be difficult to de-noise PV interters. the MPPT circuit is not analog and can turn the DC input lines into hash antennas, and as you stated, the inverter itself can put RFI on

Reuben, I differ with you on the statement that the "K2 isn't exactly cut out for data modes". If you activate the RTTY filter set and adjust the filters for that mode, then you have a good transceiver for data modes. The RTTY mode allows you to set the compression (SSBC menu parameter)
