Friends. Fun. Try the all-new

On futher research, it would seem that it would be OK
to tape (and divulge) transmissions coming over
regular radio channels, such as ham, CB, MURS, LMR,
marine, etc. The federal court apparently interprets
things that way.

Even then, the close physical spacing of the antennas may still be a
problem for filters. The best fix would be to change the frequency

I said previously, we had a commercial 161MHz Micor on
a 150 KHz split that worked without cavities, and only
about 60 ft vert between antennas. If I hadn't seen it
working, I would never have beleived it. But 60 ft
vertical is 28 dB better than 100 ft horizontal.
Joe
of isolation was the magic number
at 600 kc.

Isolation wise, vertical is much superior to
horizontal. For the example we're working on, 100 ft
horizontal would be the same as about 14 ft vertical.
To me, it would be easier to get 14 ft vertical, than
100 ft horizontal.

. This would probably be a minimum
figure, with a good clean TX and a good tight RX
without a pre-amp. Adding a notch or BP/BR cavity to
the TX and RX line would improve things also, if it
doesn't perform well without them.

I think you forgot another likely reason: The HIGH
PASS FILTER in the
mic circuit. Like the high frequency energy, there
is also a lot of low
frequency energy (below 300 Hz) on simplex that is
being stripped by the
high pass filter in the mic
function on overdeviated signals, and the LPF will
take out high freq noise, since most radios don't TX
anything above 3KHz anyway.
