"tuning plates", HR-10's et al...

[Guy G. Giacopuzzi DDS]

I'm offering some of my memory up for discussion.  In inspecting my
"new" (to me) MR-1010, I discovered the bottom panel has labeled holes
for tuning the slugs on the different bands.  I thought this was
interesting since Heath failed to do this on the HR-10 and HR-10B.  When
I worked at Heath, I remember using what I thought was a "factory
issued" "tuning plate" (bottom cover) for the HR-10's during tune up.
Once tuned, we'd take off our plate, and  replace it with the
customer's.  Thus, it would appear, that unless an enterprising ham
drilled his own bottom plate, it was close to impossible to tune an
HR-10!  If you tuned it without a "tuning plate" (bottom off), and then
put the standard bottom plate back on, it would throw all your
calibrations of the occillator coils and rf coils off! The SB-xxx series
solved this problem by having holes in the metal boxes around the coils.
 Comments from others, former Heath techs included, would be welcomed...
