[Hammarlund] Hammerlund HQ-215 Filters

[D.J.J. Ring, Jr.]

Hello Group,

Some people say that IMRAD filters (actually there is a hard to find note
on their web site about it) don't work with the HQ-215 receiver, but the
receiver manual says that 75S3B filters work in it.

I'd like a narrower filter - and when I saw the IMRAD filters and their
good prices here http://www.inrad.net/home.php?cat=103  I thought I'd get a
wide AM filter for it as well.

But then I saw this notice elsewhere:
http://www.inrad.net/home.php?cat=179 Sorry,
but our Collins S-line filters do not function in the HQ-215.

Is there a reasonable source for filters from the HQ-215?
