Ok, I promise: This is the last pic of the Hardrock 50 I‘ll toot :)
@M0YNG Thank you! It is an open source short wave amplifier available as a kit that gives you an output of 50W. There is an interface to the FT-817 which makes it possible to automatically switch bands and to trigger PTT.
When I tested it the first time yesterday night, I was able to contact a station in Ohio (20m, SSB) with the 817 and a good audio report.
