  1. Hello Barbara, I am Rick – KH2G and was playing around with websdr and landed on 3857 while you were in a QSO. I was surprised to hear you had noticed my callsign on the site and had mentioned it on the air. Unfortunately while I was able to listen in via the SDR site near Half Moon Bay (you were a good 59), the bands are not open here in Guam back stateside. 73 from an ex-Californian.

  2. Thanks for the qso tonight. I’ve been practicing cw for most of the pandemic and just started to get enough confidence to try on the air. You were great but the band was not. It was fading in and out tremendously even after you turned up your power. (It likely had more to do with the noise floor at my qth.). Thanks for your patience and here’s to next time. 73, john/ai7x
