What is the max power (dBm) a AM receiver can get in the real world? Let us say
the receiver is sitting very close to a station antenna, the station has the
max power FCC permits.


The "blackout" zone is 1 volt/meter.

Any station, regardless of its power, has such a zone.

Good city service is 25 mV/m.

The area covered by the 25 mV/m signal is a function of frequency, power and
ground conductivity.

The Raytheon manual on things to do with your CK-722 has a receiver
that uses a crystal set to develop enough DC to run a CK-722 receiver
tuned to the same station.

The obvious improvement is use a crystal set to listen to another
station entirely with the transistor radio.

It sucks a little of the energy out of the local broadcaster, reducing
his antenna pattern, so you can hear a more distant station.

Don't know offhand, but you can have fluorescent bulbs light up near a
transmitter, and you can have a crystal set drive a speaker.
