[Lowfer] WOLF!

Fri Jan 1 16:53:19 EST 2016

Lloyd,

Good to hear from you! The frequency jump is still unexplained. It ran 
right on the nose from 2000-2030. Then at 2100, it didn't start up 
automatically, so I hit Transmit. Then I noticed that the frequency 
displayed on the other computer was off by 0.7 Hz or so. Couldn't figure 
it out, so I shut WOLF down. Upon restarting, all was OK. Want to see 
what happens at 2200Z.

Anyway, thanks for the report - we've been doing this for a long time.

John, W1TAG
