Today (August 23), a fourth TRX was installed at RMS HB9AK. It stays fixed on the 20m QRG (14'110.4 (Center) or 14'108.9 (Dial)). No scanning - it will respond immediately to any connect (unless it is busy already on this QRG).
Furthermore, an SCS Tracker was added for 20m, so it is possible to use Robust Packet Radio in addition to Pactor 1-4 and WINMOR. Robust Packet service on 30m remains available as before.
