[Hammarlund] Hammarlund Digest, Vol 63, Issue 20

[njmikec at optonline.net]

Interestingly, even with two sump pumps, I had a flooded HQ110AC and basically followed Ken kb7rgg outlined below.  Lesson learned, get the dirned radio off the floor!  Just dumb.  

Only difference was that I didn't bake it.  I let it sit in the sun for a ~5 days with the transformer covers off.  Besides the transformer, my other concern was the IF cans which seemed to dry out well.  IIRC, the cans were a daunting prospect to remove.  Very low pressure compressed air and sun seemed to do the trick in the if chain.  The only thing I had to replace was the S meter which never came back despite disassembly etc.  Good thing for disk caps!  I love the 110 series.  When aligned well it's not a bad little boatanchor.

Good luck! 73 Mike kc2oso
