Hi:

If my location is in southern California, what would I hear on a
"DXed" 300 GHz AM Radio Receiver? Would there be a specific difference
between what I would hear at night and what I would hear during the
day?

On medium-wave station, I notice the interference -- in the form of
tones -- to be louder at night than the day. Does this difference also
apply to extreme shortwave frequencies as high as 300 GHz?

NOTE: I am aware than 300 GHz is most likely FM, not AM. However, am
still curious as to what I would hear on a 300 GHz AM receiver.

Thanks,

Radium - Most likely without the 'right' Antenna
and feed-in-line for your device {Radio} you will
not hear anything. ~ RHF

Point-of-Clarification : Does this Device {Radio} clearly
read {labeled as} 300 GHz or could it be 30 MHz

=IF= 30 MHz then you have a Shortwave Radio.

* Radio Signals in the EHF Band are Extremely Prone
to Atmospheric Attenuation, making them of very little
use over Long Distances (No DX).
* The EHF Band is commonly used in Radio Astronomy.
