Yesterday morning, idly running FT8 on my QMX when there was a CQ from New Caledonia, and ATNO for me.
The signal to noise was 0 to -5.? That's from half way round the world!? Tried calling but nothing so got the 7300 going and made the QSO, using about 90W. Cheating, I know but it was an ATNO.
The 7300 gave the S/N as -16 to -18.? Ran both at once in Rx and it was consistent, QMX -3 to -5, 7300 -17.? Similar antennas (EFHW and doublet side by side).
I'm not complaining but wondering why there should be such a difference, the 7300 is working nicely and this difference doesn't seem to be consistent,? I might try analysing the ALL.TXT files for the two systems to see if I can see what's happening.
