[Lowfer] ARRL article on VLF activity & 137.7775??

[Michael Sapp]

Garry: I believe that was in the recent ARRL letter. I bounced a copy over 
to the local club e-mail reflector with a few capture links a few
days ago. Hopefully one of the retired submarine jockies up there will 
notice it....

For 9kHz I would have to toss the DBM approach.  I noticed the ZLW-1 
datasheet had plots for up to 10dBm LO drive yesterday
and given that it's  losses increase under 100kHz to DC  I decided to go 
from +7dBm drive last nite to +10 dBm. Not sure if it made much
difference last nite,  but it did not appear to hurt anything.

Currently I have the DBM-OCXO converter on 137.78 monitoring MP and noticed 
a signal at 137.7775 which
may be XKO. I had setup with  the EWE pointed NE to get away from the wx qrn 
and possibly catch VO1NA later this afternoon.
Switched back to SW so I will known in a half hour or so who is on 777.5
