G'day all,
I have a 1955-vintage Collins R390 here and am curious about whether anyone
on the reflector has done any comparisons on 160m with the 75A4 - or what
anyone who has a R390 thinks of its performance on 160m.
My R390 is in original unmodified condition and I am not a vintage
collector (i.e. am not concerned about modifying it), so am also wondering
if there is anything I can do do improve its 160m performance.
My other idea is that I might be better leaving the R390 'as is' and trying
to find an AM SWL-type of person who is more interested in this type of
radio, trading/selling it, and then looking for a 75A4 instead. Looking at
the R390 circuitry it seems an pretty amazing receiver - probably more
sophisticated/complex than the 75A4 in its design.
What lays behind this is am putting together a 1950s type amateur station
for 160m. For the tx I have a Panda Cub transmitter from the UK, with an
807 PA. This is a commercial unit, made entirely from world war 2 surplus
parts. This weekend, I'm building a pine console/radio shelf to house the
equipment - great fun!
Vy 73,
