[CQ-Contest] Phase noise

[dr. Marko Munih]

 Barry,
 
 I have the same problem from my s50k location when working JA
 direction. s50e club contest location is approx 10km on the
 other hill-top with direct visibility between us. Last time
 when this was happening the other guy used FT990, I think,
 my radio is 775. There was no receiving noise from my side
 on his radio, while he was constantly up to S8 here. 
 Rx attenuation in my case did not help.
 Just my oppinion, based on no measurements, says that this is
 phase noise of his radio.
 
 Regards,
 
 Marko s50k
