Today I grabbed a little time on HF with the K3. I was pleasantly surprised to find 10m and 12m were open, so I listened around on those bands. I worked a Welsh station, GW4BKG on 12m SSB and was pleased with a 55 report for my 10W. Later I worked a mobile Italian station on 12m operated by Claudio, IW6DRH on SSB. That is the first time I believe I have made transatlantic contact from my QRP station to a mobile station, so again was pleased with him picking up my call first time. Claudio was 57 to me with some QRN and he gave me a 55 report. The antenna I was using was my homebrew 90ft doublet.
I later found some videos of Claudio on the web, so here is one that shows his mobile setup and him operating from his car. Thank you Claudio for the contact and the video!
