[Lowfer] WH2XHY

[Michael Sapp]

Garry:  I had 50 or so double captures of XHY last night with 120Hz spacing. 
His signal was very close to XXM, so I
thought some mixing may have been going on (my converter or IF radio) 
between the two signals.  With a level 23 LO and mixer here, he did not have 
the signal levels to
cause such an effect by overloading my mixer. His SNRs were not strong 
enough to do that....

2015-02-26 09:50   WH2XHY   0.475723   -6   0   EN52hx   1   WA3TTS/2 
EN90xn   819   106
 2015-02-26 09:50   WH2XHY   0.475603   -15   0   EN52hx   1   WA3TTS/2 
EN90xn   819   106

Occassionally when I get a double capture it is because I left my noise 
blanker on accidently, and the limited
dynamic range creates issues in the FT-817 IF receiver. That was not the 
case last nitght as the XJM and XHA locals
were not causing problems with +15 and +11 SNR levels....

73, Mike wa3tts
