Hello Peter,
that's a good question. Some users of our Fury use rented/borrowed survey
equipment (Leica, Javad, etc) to get a very precise position of their antenna,
or they call in a surveyor.
It is also possible to let the receiver do the auto survey multiple times,
preferably during
I recently uploaded a manual for the 10638A Degausser to KO4BB's website. I
checked this AM and it is available for download.

When I look at the catalogue, the description says:
| UTC Receiver Module, 60kHz, no CPU | 561-1014-ND | 10.70 | CMMR-6P-60 |
I have looked at modules like this before but what I saw was much more
expensive. So I'd like to get one at $11.00.

One thing you can do is connect it to a PC via a modem control signal.
There is software at:

Hi Jamie:
The same company makes a number of LF time code receiving products. Their
top of the line model combines a ferrite loop antenna, made to have very
specific properties, with a three band receiver that resonates the antenna
at either 40, 60 or 77.5 kHz by switching caps. The included

I recently acquired a couple of FTS 4100/S12 cesium frequency standard
modules. These are, I've been told, basically the guts of a 4050 (and
maybe 4060?) commercial standard repackaged for military fly-away use.
They run from 22-30 volts and have a couple of switches and a meter
jack, but

Yes. It would be 10 MHz or 20 MHz, depending on coding. Or 5 MHz, so the
transitions are at 10 MHz. I don't recall, or never knew.
