[VHFcontesting] Problem on 50.125

Hi Bill,

I have two old PCs that plant a carrier right on those frequencies. At 
times these carriers are pulsating. So far I have not been able to 
isolate which part of the PC is causing this, but I have a suspicion 
that the ATA bus is the culprit. Some 20 odd VHF cores inside and 
outside the PCs, and attempts to seal the PCS did suppress it somewhat 
(from S9 to S0), but an S0 carrier is still annoying and making the PCs 
useless (especially with the virtually useless ANF in the FT-897).

Anyway, I thought I'd throw that in there for something to look for in 
case you determined it's local. However, it does sound like you're 
dealing with a different source.
