Al 
I wanted  to let you know I confirmed RNB from New Jersey on 363KC this
morning at 4am.  I had run across it on  Monday but I couldn't confirm the
Call sign as it was very weak until this morning. I got the first to letters
but the last letter all I was hearing was the dash and then two dots on
Monday but then this morning I copied the whole call as one group so it made
it easier to understand.  This station is a 50 watt station and I was coping
it on my Inverted 80 meter dipole. I found a VLF amplifier and I am looking
at the Minwhip. Any comments on MiniWhip?

Thanks
Mike

Mike,

I've been messing around with this a bit since this thread started.

Here's a freq. list I really like:? https://www.mwlist.org/vlf.php

I'm pretty crippled here in Jersey City, with outrageously strong NYC AM 
stations.? Even so I can do a bit of VLF receiving.

The following recording was made with half my low 100-foot doublet 
feeding an SDR-Play receiver via a 60 KHz low-pass filter. Software was 
HDSDR.? I feel that in our area, NAA on 24 KHz is the place to start.? 
WWVB on 60KHz? is also amazing strong, and easy to recognize (1 Hz short 
and long pulses).

This screen capture should give you some idea what your listening for. 
(CW mode)
http://www.ar88.net/vid/NAA%20+%20WWVB.m4v

Stations recently logged on a 3-foot 16-turn shielded loop in the attic;

?21.4 KHzNPM Lualualei, HI
?24 KHz ??? ??? NAA Cutler, ME
?24.8 KHzNLKJim Creek, WA
?25.2 KHz??? NML4Lamoure, ND
?37.5 KHz??? NRKGrindav?k. Iceland
?40.8 KHzNAUPuerto Rico*
?60 KHz??? ??? WWVBFt. Collins, CO
62.6 KHzFUGFrance??

These are ID by modulation and exact frequency.? The SDR is helpful at this.

Fire up your receiver!

Al

Yes Mike, I'm aware many of the ARC-1's were replaced by RT-58/ARC-12s so
that impacts finding control heads.  It should be noted this is not the same
as the AN/ARC-12 built by Aircraft Radio Corp which uses coffee grinder
style control heads.
