Generally speaking, most predators make very poor eating because of thier
own eating habits in addition to the general starvation they put up with.

You will also reccomend spacing of both transcievers several miles away.

I am not an expert, but the first mic circuit would need an impedance
transformer, to keep the indivual mic circuits balanced or the audio level will
be less.

We're not talking hi-fi here. Many radios are
nominally 600 ohm input impedance and it's definitely
not critical. Sure, you could end up with a 300 ohh
load, but the mikes also have preamps in them, so they
probably don't care either.
Just talk 3dB louder.

Add a TX-RX diplexer (the model made for tower-top use) and you've got a
commercial-spec dual band antenna. Install it properly and you can ignore
it for 20

As we have had many issues with our 220 PLL exciter with microphonics and
other noise, most of this was traced down to the final amp stage. This stage
uses a Phillips to-38 style transistor which has the collector commen to the
case, and Hamtronics puts a big heatsink on the case! Needless to

Overall real performance isn't where I'd like it to be, I suspect the

About 8 years ago, I tried using a Comet GP-9 antenna combined to serve two

better on 2 meters than on 445 MHz.
