[ARC5] Zero Beat Question

[Peter Eijlander (PA0PJE)]

Hi Sheldon,

Interesting to read.

In those 1960s the Dutch Army relied on AN/GRC9, GRC3030, GRC3035, 
SCR399 (BC610) and AN/GRC19 for communication, mainly CW for it's better 
range. Voice was on low VHF AN/GRC5 and AN/TRC-3. SSB was more a 
ham-radio affair with self-built filters from FT-241 crystals on 450 kHz 
or phasing networks.

Thanks!

73,
Peter
