[Hammarlund] HQ-215 queston

[Dave Wood]

Gang, I am starting restoration of a HQ-215 with a gain issue.  Overall, the
gain seems real low as far as noise output with no signal, and this is in
addition to the known front end problem it has.  I was wondering if anyone
had ever documented stage gains for this unit?  Of special interest would be
the overall gain of the last if, the loss through the Collins mechanical
filter and the level of the first LO injection.  Thanks in advance.  Dave
