This will be buried inside a completely unrelated thread, but there
are lots of "low power",
Part 15 100mW, devices in the MW band. There is a Military Graveyard
just about 15
miles south of me that has such a transmitter for "self guided
tours". I have seen/received
several "talking houses" including a solar powered one that I was very
tempted to visit
under the cover of dark and appropriate for my own use.

I have seen a few billboards with these also. Down toward Tennessee
the big firworks
outlets tended to use them about 8 years ago. I don't know if they are
still in use cause
I don't get down there these days.

Regarding my hunt for the UNID 1640 station rebroadcasting A NOAA
weather stream,
I had assumed by content it was at or near Cave Run Lake, near
Morehead KY. But we
visited there Friday and no signal. I talked to the Corp of Engineers
and they suggested
we check in Jackson. So off we went. As we approached Jackson it was
clear it was
not there. But I decided to check the Jackson Airport/NOAA office to
see what they knew.

They were aware of the TIS stations in Winchester and Richmond that
carried NOAA
and were for use in the event of a nerve agent leak from the Blue
Grass Army Depot
in Richmond, but they knew of no station on 1640. They gave me a list
of towns where there
are low powered NOAA WX transmitters to check and it wasn't in any of
them. On a lark
we went to Richmond Yesterday and the TIS on 1610 is still only
receivable right next
the the emergency center. But there was a different station on 1640.
This one is clearly
connected with the Nerve Agent program and may be in Berea.

Sooner then later I hope to locate both 1640 transmitters.

I will post the main body of this under a new thread.
