[RTTY] RTTY skimmer observations

[John Holmes]

Wes, thanks a lot for your research into this. I noticed that your spots
were much closer on 40M and, as was previously posted, the 20M and 15M spots
were off by about 400 Hz.
Thanks! 
73 from the VERY cold Midwest.

am certainly motivated to find solutions to these issues.  I thought I had a
definitive way of calibrating my spot frequency but it obviously isn't
working.  I will spend some time this week looking at the W1AW RTTY
frequency.
