[Elecraft] ARRL 10-m contest

[Bill Davis via Elecraft]

 After reading Burt N4CW comment ... I have a 3" muffin fan laying on top of my KXPA100. I use a series resistor in the 12v source and the fan runs at reduced speed all the time. Receiver noise  masks the fan noise and I can run RTTY , PSK etc non stop with a "cool to touch" heat sink. I have been very active chasing the ARRL Centennial stations, so considerable RTTY and a bit of PSK31. 

  Been a ham 59years and the this was first 10m SSB contest I ever participated in. Also first time I ever used the N1MM logger+. I had a good time using non-resonate 80m and 40m dipoles and the KXPA100 driven by my K3/10.

I used my KX3 and KXPA100 for the 14 hours I was on. I recently had gone  
through the rx sideband nulling procedure and really enjoyed single-signal  
reception. The amp got pretty hot...it definitely needs external cooling of 
some  sort. I didn't take any PA temp readings, but the heatsink was  
uncomfortable to touch during long spells of "running" at 100W output.
 
The KX3 is an outstanding performer, even if QSK isn't as quiet as the K3  
with FW 5.01 :~)
