I believe many of the GWEN sites were converted to VLF beacons transmitting
differential GPS reference data.
I know of one site in Crownsville, Maryland that does just that.
I don't know the up to data status of these sites now.

The only ones I know for a fact were former GWEN sites are Essex CA and ABQ NM.
I can hear 29 +/- of these with an indoor loopstick in the winter when conditions are quiet.

Well, it could have been ELF whose Seafarer antenna was located at Clam Lake
Wisconsin. My grandfather built a vacation cabin just north of Clam Lake
and it was a big deal to visit the place. That was before the peaceniks
were demonstrating since they didn't seem to want our submarines to do too
much damage to Russia. I think that antenna was almost 30 miles
long---don't quote me but it was an important component in the very low
frequency communications system of the Navy......

I believe they called that system a "bell ringer". It let the sub know that
it had to come close to the surface to receive new information. I'll need to
google around to find more about it.
We had a ELF transmitter (NSS) in Annapolis that transmitted about 1 MW at
about 24 kHz. Anyone ever seen 3 inch diameter litz wire?

Tom

We had the ELF transmitter at Grimeton (SAQ) transmitting about 200 kHz
at 17.2 kHz using the Alexanderson alternator. I think the litz wire was
4 inch in diameter as I recall it. It was cutting edge in 1924.
It was initially used for telegraph traffic to the US, and the Long
Island main station. It was really never keyed by hand, it was keyed
remote with optical keyer and messages taped back-to-back. After its
main service for telegraph messages was no longer motivate it, it got
used as the "bell ringer" for our subs and kept operational and
maintained up till about 1996 and it has since been taken care off so it
can be used for museeum. It's now on UNESCOs world-heritage list.

Do visit Grimeton if you are in south of Sweden. You can also tune in to
it's transmissions and report back.
The remaining submarine radiostation in Ruda could actually be turn into
a time-code transmitter. It's a matter of financing it and giving the order.
Cheers,

I believe ELF is more like 100 Hz, which can be received much deeper, so the sub can stay at the bottom. 24kHz is VLF.
