Peter : True, but at the time, despite phase noise,
my 210X helped save many lives.

Ah! The Atlas 210. The rig that boasted about its crystal filter but couldn't use the full stop band close in because of phase noise!

The ATLAS 210X, for example, offered a flexible solution:-
5645 kHz 8-pole crystal IF filter + two carrier oscillator crystals,
switchable to either side of the IF for "normal" or "opposite" sideband.
This was very helpful when netting with fixed-channel
medical services in Africa.
