[Elecraft] XV-144 Stability

[David Pratt]

Yes, Eric, like you I usually switch on my XV144 for about 20 minutes 
before I intend to use it to allow the crystal oven to get up to 
temperature. Then, it is nice and stable.  I did have the Mitsubishi PA 
module fail on me and had to replace it. I have also fitted an internal 
fan similar to that used in the XV432.  Since then, no problems.  In 
contrast, my internal K144XV drifts almost 100Hz in five minutes, even 
after allowing 30 minutes to 'warm up'.
