[Elecraft] SSB and MH2

[William Johnson]

Low and High on SSB is also in the perception of the listener.  If you think
they are on a specific freq. and tune using that then you may be off.  I
listen to nets where the net control can be off 50-70 Hz and I tune
accordingly.  Some "lids" think they are right on all the time... :-)

On the recent topic of SSB audio reports, I got report of "off 
frequency" and "too low" on 17M USB today and have not found the problem 
yet.  RIT and XIT were off and 15MhHz WWV was within 5Hz according to my 
sound card.

I did the bandwidth mod while I built my KSB2, following the advice 
given here, and in the new KSB2 manual -- just about a week before the 
parts kit was announced.  At first I got reports of weak audio, and last 
night ran through the entire Spectrogram alignment (once on WinXP with 
my wife's computer, once on Linux under WINE).  Now it appears to be 
better, but there is still something wrong:.

This morning I was able to work KH6BB (USSS Missouri, Pearl Harbour, 
Hawaii) on 18m and got in the first time.  Op Lee reported that I was 
"off frequency" and "too low."  Any idea what to check for?  The 
spectrogram plot looked a lot like the one in the paper...
