Which 300GHZ AM receiver did you have in mind?

Any theoretical 300 GHz AM receiver. I want to listen to signals from
far outer space.

Hmm...I'm going to guess the SN ratio will be quite low when tuning in
hypothetical signals on a theoretical receiver.


Since AM is more susceptible to magnetic disruptions, I'd figure, and
AM radio is more likely to pick up interferences from outer space,
than an FM radio. The question is, which frequency is best for this?
Frequencies that are too low are sealed out of the ionosphere, while
frequencies that are too high rapidly disappear [line of sight].

Look into the SETI project instead. There are established reasons for
tuning around 1420mz and the project is organized.
