Thatcher,

Some receivers have a jack that makes the AGC voltage available, if your has
that a sensitive voltmeter could be used there. If tracking on 2 meters,
there is some advantage to monitoring the third harmonic on the 440 band, or
use a local oscillator-mixer technique to offset the frequency you monitor
to minimize the likelihood of
over powering the receiver.

Alan Broadband company makes a device they call
"Zap Checker" Used by some for tracking.
You might look at www.zapchecker.com see if you could use it. I have a model
180 that has both linear and log response.

Why would holding the antenna behind the reflector pose a problem? I think
most doing animal tracking know little about RF and are not using the
equipment they have to
their best advantage. Also possibly using the wrong frequency for the
application. I have talked to some
Federal Rangers about the animal tracking they do and they have little time
to learn the best techniques and possibly little incentive to learn and
apply.

I hope you are successful in your tracking.

Best wishes from ray

I've tried doing a google search but came up with nothing.

I noticed on TV when tracking animals with TX collars they hold the
3 element beam behind the reflector. Seems that this would be a problem.

I have a HT that I want to DF with.... How and where would I connect an
analog
S-meter like I've seen on TV.
