[Heath] HW-101 LMO IN HW-100??

[N4ch at aol.com]

I have an old friend (whom I've known for about 45 years) who  built a 
HW-100 when it was new, back in 1968-69.   A year or so later,  when Heath 
announced the HW-101 (with the new dial drive, provisions for adding  a CW 
filter, a marginally more sensitive receiver, and maybe another slight  change or 
two besides the obvious cosmetics), he got with Heath, and ordered  
everything he needed (including a new front panel and the new plastic  escutcheon) 
to fully update the rig from the '100 to the '101.   I  guess the big 
question I'd have is whether or not the "new" (Jackson Brothers  6:1 reduction) 
dial drives could be easily "fit" behind the "old" front panel  (which used the 
much-maligned "Harmonic Drive" mechanism.   I guess  the best way to get an 
answer is to disassemble one each of both radios' front  panels, put them 
side-by-side, take a good look, and make a few  measurements.   I'd think 
that (in addition to the new plastic  vertical escutcheon that was added to the 
front panel when Heath did the  re-design) there would be at least a 
handful of "new" mechanical items (besides  the two Jackson drives) that would be 
needed.   He sold the radio to  another friend of mine (via a mutual 
acquaintance of ours who owned the radio  for a few years, who had it in his shack 
for 5-10 years)........I THINK the  radio is still in the area here, and 
(hopefully) the "new" owner can locate the  paperwork (I think the original 
purchaser of the gear originally got the  original HW-101 manual shipped with 
the kit, and he bought a HW-101 manual along  with the parts for the 
"update").   I hope there are some pages of  notes in there, indicating what all he 
actually changed out.........if U are  interested, I'll see if I can 
"borrow" all this, and see what all had to be done  to update the dial.

Hi,  everyone! My HW-100 is a really nice example and works very well. The 
Tuning  Knob, even if installed right by the book, has a lot of drag and 
isn't as  smooth as the Jackson-drive HW-101. So, a question: has anyone on the 
List put  a HW-101 LMO into a HW-100, and added a Jackson drive to the 
front panel?  Seems as though it would be a direct substitution. And, it would 
really smooth  out the Tuning Knob.
