[Hammarlund] hq-180a

Sat, 16 Aug 2003 19:32:55 -0400

Hi Eddie et al,
    Well, that's why they went to the "A's."   That did help most of them,
at least.  I had an HQ-180A over a yr ago, that I thought was terribly
drifty.  I finally realized that I was turning the whole thing off with a
pwr strip, I was using it in my shop, not in the regular shack.
    I have converted 2 HQ-170's to "A's", that helped them a lot, but
you're right, they were not good.  I ran some curves on them each way,
can't find that now.
    Dan sent me a note that he does have his on pwr always, so it should
be better.
73,
Al, W8UT
