[Milsurplus] Less range at night

[Rob Flory]

"For some reason the above has rekindled for me a question that no one took
on earlier.
A German manual I was reading, specified the working range of an HF field
radio as
less at night. If I recall, the radio was a Torn.Fu.b. which works about 3 -
6 MHz at about
2 watts input, but -- about size of BC-654.

An underpowered low HF radio on AM could be considered too weak for sky
wave use, especially with a whip antenna, but subject to the higher level
of interference at night.
