"Somebody check your mike on the radio, please..."

Very well, thank you. A dissertation on *mod would take me the better part
of a semester to convey, as it does now. My Spring semester classes are
still open (www.sierrracollege.edu) if you'd like to partake.

Not only is it remarkable selectivity, but crossmod, intermod, and all
the rest of the *mods combined with the antennas less than 5 feet apart,
a 10 watt transmitter and a 1 microvolt receiver. One might be tempted
to call it a miracle.

I remember some of this vaguely from when I was active with amateur radio
but all that info is long gone. How does it work then?

I do have a homemade radio level meter plugged into the headset jack to
tell me when there's traffic on the frequency. Works well.

Please elaborate.

I can't describe the circuit, being an electronic dumbo. A friend who
is a ham made up a circuit board inserted into a Radio Shack case about
the size of a cigarette pack. A 9v battery drives it. It is Velcroed to
the top of my C150's glare shield. One cable plugs into the headset
jack and there is one large LED on the case that flickers when there is
traffic on the frequency. Cost less than $10 in parts to put together.
