[HBR] HBR's in 2014?

[Brian Burns]

Hello All,

 

A lot of water has passed under the bridge since Ted Crosby designed the HBR
series. I've been wondering lately how well HBR's have come out of this long
trial period. Things like how many are still in use as the station receiver,
and how adequate they are under today's band conditions etc. Just musings,
you know.

 

Doing a bit of SWLing with my HQ-150, the bands don't seem as crowded as I
remember their being, back in the day. Perhaps my obsession with selectivity
is misplaced?   

 

If I remember him rightly, Carl KM1H, said that selectivity gotten with
tuned circuits, I.F. strips, not crystal filters or Q multipliers, leaves
the signal sounding better. Certainly the high Q devices like crystals tend
to "ring" a lot at narrow selectivity settings. Any opinions?

 

Cheers,

 

Brian
