[Hammarlund] Hammarlund HQ-160 audio

Mon, 12 Apr 2004 11:32:53 -0400

Gary,

I see the same thing with mine.

The 160 is 1W audio out with a feedback arrangement that is described as 
narrowing the audio bandwidth on weak signals. My 129x at 3W out sounds 
much better. Maybe it's just a matter of power to drive fast transients 
through the speaker.

Compared to my NC183, or SX-62, thier both pretty wimpy, but what great 
boatanchors. The q-multiplier works great on the 160. The xtal filter on 
the 129x is sweet, and for some reason I havnt fathomed yet it seems to 
handle noise better than the others despite the tales of noisy 6ss7's 
I've read/heard.

I'm home for my 50th birthday today spending it aligning an HQ-180 I 
picked up at a hamfest last weekend, having a great day so far! I have 
high expectations for this one.

Larry, kzoe

>I just purchased an HQ-160 to add to the Hammarlund collection here.   It is the first 160 that I've had any experience with.   I was under the impression that it was grouped right in there with the 100's, 110's, and 145's, in terms of their pleasing audio capability, based on comments that I've seen on the web.   I immediately noticed that this one was quite inferior in audio quality to my HQ-100.   It is not as bright, and has very little low end.    I even subsequently did a popular audio mod, and it still doesn't compare to the 100, which is completely stock.   Tubes check good, and were changed out anyway, with no difference noted.   Any suggestions or comments would be appreciated.
