So, how many here have experience with the 180 ??
I understand the 170 is more stable and a better receiver...
Anyone care to comment on this....???

I don't ham much anymore, but if I get a Hammarlund
I want to know what I might have to modify to get it working
well.... Anyone with experience in stabilizing/rebuilding/repair
on these Hammarlund models might like to talk about their
experiences, and I would like to listen...

73s from Andy in Eureka, Texas W4OAH

I had an HQ170 in the late 50s. It drifted a quite a bit and also
suffered from tunable hum. At the time, I lived in an apartment in New
York on West 34th Street and Hammarlund was in a building directly
across the street. The company I was with did some work for Hammarlund,
so I knew several of the engineers. They were aware of the problem with
the HQ170 L.O. So they decided to offer a mod kit, but did not want to
go through the hassle of writing detailed instructions. They figured an
experienced ham should be able to modify the circuit from the "before
and after" schematics.

Since I had been a ham since 1939 and was a graduate engineer to boot,
they gave me the kit of parts and told me to let them know if just the
parts kit and schematics would suffice. I got it done, but it took
about a dozen phone calls to their project engineer. Needless to say,
they abandond the idea of selling such a kit.

I assume that the later production runs of the receiver incorporated the
changes, but I do not know for certain.
