But the amplifier you're trying to use is meant to feed a receiver
directly, not another antenna. So output is going to be very low (on
the order of microwatts) - much lower than any amplifier which feeds an
antenna.


Small point, but.... Microwatts. Those new legal microstransmitters
are said
to be in NANOwatt range output, but allegedly work on the distance
scales I'm
interested in. Microwatts should certainly have worked, but despite
the crude
test dipole being good (on standard wired reception test anyway), it
didn't
work for transmitting even a foot or two with the radio's whip
parallel to
the upper part of it. If nanowatts should have, the MAR-6 looks like
driving
picowatts, if I'm lucky.


I would suggest you check again. Receivers aren't that sensitive. Most
unlicensed transmitters are in the 100-500 mw range, and have a coverage
of maybe 100 feet. And picowatts aren't even worth discussing.

I'm unclear, is mW microwatts or milliwatts as you wrote it? The reason
I ask is that a 500 milliwatt transmitter would certainly have a
receivable distance much greater than 100 feet, no?


According to standards, mW is milliwatts. uW (actually, greek "mu"W but
I'm not using a charset here that defines it, so the standard is "uW")
would be microwatts.
