[Hammarlund] hq-145a specification

[Richard Knoppow]

     I don't know and couldn't find any specs but did fine a good 
PDF version of the instruction book including an insert for the 
fixed frequency crystal local oscillator. Its at:
http://www.jamminpower.com/PDF/HQ-145.pdf
    Much easier to read than the Deja Vu version on BAMA.
    If you think there are problems with performance I suggest 
you ask here. Meanwhile I am looking for something with actual 
performance specs similar to the production notes book from 
National which is on BAMA.
    BTW, I am in the midst of working on an HQ-129-X. I have had 
this receiver for several years but need to fix some problems. 
Once I get them fixed I will post here for others who may have 
the same ones.
    It is essentially a very nice receiver but has some puzzles, 
for instance, why did Hammarlund decide on the inside out dials? 
I call them that because the low frequency band is on the outside 
and the highest frequency band on the inside, just the reverse of 
most receivers and just the reverse of what you want to get the 
best calibration resolution. HQ-120-X is the same. I don't know 
about later receivers in this line like the HQ-140-X.
