The QRSS-"boom" came later, when solutions like Spectrogram and QRSS became available and more stations realized how easy it was to get QRV in QRSS. So let us see ... if I interpret Lyle's tests correctly, there is still an improvements of about 6 dB to expect if we switch to a slow synchronized mode ... maybe exactly the 6 dB some of us need to cross the Atlantic (still I only got about 200 mW ERP, my trial of increasing my output power of thr G0MRF PA lasted about 10 seconds .. before my FETs exploded ...). Geri, DK8KW (W1KW) --------- Yes, what I was really trying to say was that it was not a change from QRSS to BPSK in Europe. It was more that stations were becoming equipped with both modes, though rather slowly. Just sitting here on Christmas Day waiting for lazy Number 1 son to get out of bed so we can open the family's presents! I will be in GW between Christmas and New Year, but only active on receive.
