Thanks, but all of the credit goes to Dave Nelson for dreaming up the

That particular FMES is in a vault and I live in a generally quite
place. The vault is about 60 yards from the house and I get the signal
to the house via TCP/IP. The digitizer is a single channel 24 bit $150
device from www.symres.com which goes into an Earthworm transport
buffer and then published on the internet. My other FMES's are on a
WinSDR system. I must add that my Winsdr board also exports to an
In its most simple from and FMES can be built in an afternoon with
stuff you can get a hardware store. The fluid is made conductive with
distilled water a .5% antifreeze and .1% anti-foam (Rug Doctor fluid).

I am sure that there are hundreds of ways to configure an FMES, these
just a few.
I will be on vacation for the next three weeks (starting the 28th) but
will be but will try to check my mail and will be glad to help anyone
get one of these going. I am sure that Dave will help also.
I will try to write a bit more after dinner. I talked to Dave and he
is going to pipe in.
