[Boatanchors] HQ-170A

[Carl]

Its unfortunate but it may have been a sign of the times as Hammarlund was 
on the way out and probably went the cheapest route in selecting component 
vendors.

National and Hallicrafters werent any different at the end.

What I always find amazing is how stable and sensitive the old catacomb 
tuner Nationals are. I have a NC-101X, NC-200 and three NC-240D's that are 
very useable on SSB. They outperform any of the competition of their era 
including the SX-28 and old Super Pros.

Same with the HRO's going back to the early 1935 model I often use.

You have to give James Millen a lot of credit for his innovations.
