Anybody up for #hamchallenge #hc30 @hamchallenge? I can do digimodes, ssb or (bad) CW and I'm also in #POTA. Bands 20 and shorter. I can load the antenna for 30 or 40, but the best results then are cw/ft8 around Europe. Reply with qrg/mode
@hamchallenge The condx were terrible and I really, really hoped for a 6m qso, but nothing happened. I did hear F4JRC, about 2000 km away, on the magic band #HC28S. Contacting other xOTA stations wasn't as easy as the usual P2P or P2S, but
20m and higher, cw, ssb or digi, qrv for a few hours. Got a decent setup here in #pota too. I want a qso for #hc30, maybe even #hc31 if you can do odd digi modes. @g7kse boop?
