Jay, Ward,

Be careful, it could be that your GPS 1 PPS leaves a 'fence' of 1 Hz 
sidebands in your signal stream, at least when looking deeply into the 
noise. To avoid this, it is sometimes better to avoid transmitting on 
integer Hz frequencies.

Currently VO1NA is transmitting on 8270.0075 Hz.
DK7FC is transmitting on 8270.1 Hz.
Maybe it is helpful if Ward moves a bit away from 8270.000 Hz, e.g. 0.1 
Hz down, to avoid interferences from and to VO1NA. This way you can 
exclude the eventuality that someone detects his own 1PPS signal instead 
of your carrier.

73, Stefan
