I called CQ using QRSS3 on 137.7kHz at 0850 and 1630UTC, but no reply. Static was bad on that band.
I retuned the antenna to 500kHz and received the following stations using Op4 (best signal/noise in brackets): G3XBM (-13dB), M0FMT (-1), PA3ABK (0), PA0A (0).
Listened on 477kHz but no amateur signals heard.
