Hi LF

M0DSZ decoded me in Opera Deep Search last night at 1596Km, so ODX so = far

= 04:53    136 EA5DOM de EA5DOM Op32 0 km -10 dB F:1%_End in Albir = 1510,3 Hz

Moving the zoomed section of the spectrogram to your QRG shows a good = and narrow (albeit slightly drifting) central carrier. This means that= your version of the U3 is keying coherently with continuous carrier p= hase, helping opds to reach it's full sensitivity. According to earlier observations on MF, there also other Ultimate ve= rsions out there which apparently reset the DDS during the gaps, produ= cing random-phase symbols with no continuous carrier.
