[Hammarlund] HQ-170 vs. HQ-170A - Differences?

[Craig Roberts]

Hi Roy,

I acquired an HQ-170AC VHF last year (it's an HQ-170A with clock and 6 
meter converter included). It's a very nice set and was a very easy and 
quick rebuild. The chassis has a nice, open layout with no tricky 
corners or unduly buried components.

Hammarlund built it as a communications receiver so the audio's 
restricted and can't be opened up much in the stock configuration.  It 
drifts a little bit when compared with my Collins 75S-3 and dial 
calibration isn't as precise.  On the other hand, the greater 
selectivity choices and addition of the 160 and 6 meter bands make it 
nicer in those respects.  I'm very fond of my HQ-170AC VHF. You'll like 
yours, too, and -- best of all -- you can get it back to factory specs 
in just a weekend or two. It's a triple conversion set, though, so 
you'll need a signal generator that goes down to 60 KHz for the alignment.

73,
