I am getting a Hammarlund HQ-145 and would like to get some
of the
groups opinions on the radio, compared to the competition
at the time.
I am looking forward to getting the radio, as a kid in jr.
high, my
dream was always an HQ-180!
Thanks in advance

The HQ-145 was the last in the line that started with
the HQ-129. It has essentially the same circuit but uses
miniature tubes and has a voltage regulator and temperature
compensation.
These receivers have a single RF amp stage so the image
rejection is not high but they have three IF stages so
selectivity is actually pretty good. Also, Hammarlund had a
patented crystal filter which was easily the best of the
bunch. Collins used the same circuit in their receivers.
This series was intended to be a medium-price adjunct to
the Hammarlund catalogue. Their top of the line receiver was
the Super-Pro which was also the most expensive receiver on
the market during most of its life.
In general Hammarlund have very good quality of
construction and good design. The dials are directly driven
(no dial cords) and have a very positive feel.
The HQ-145 is interesting in that Hammarlund, who
indulged in rather small knobs for decades decided to use
extra large ones on this receiver and on the SP-600.
There are instruction manuals on a couple of sites, BAMA
for one.
