Hartmut, The signal on 505.75 is probably WD2XSH/17, Dave Riley (AA1A). He runs regular speed CW most evenings after 0100 UTC or so. John Andrews, W1TAG On 505.75 kHz I captured a CW trace on my QRSS
137 kHz: Captured UA4WPF 19:10-21:05 on 137.7772 kHz. Some traces were visible on 137.776 01:20-03:00 but nothing readable. Capture of UA4WPF can be seen here: http://www.h-wolff.de/LatestLF.htm 500
