Dick,

I turned off XRS5 just after 1 p.m. as shown on your 3rd screen.   As 
the temp warmed above freezing the antenna matching was way off.  The 
blip on your 4th screen is a test I did after adjusting the antenna 
matching.  It was a bit after 7 p.m. when I powered back up.  I turned 
the beacon off  between about 9:30 to a bit after 10 p.m. because it was 
interfering with my 432 mhz QSOs.  Initially I thought the noise I was 
receiving on 432 MHz was corona but I saw no indication of corona on the 
scope match waveforms.  I sure hope the noise wasn't corona.  The power 
on 74 kHz is only a bit over 100 watts.
