[Hammarlund] HQ 129X Serial numbers

[David Thompson]

If someone can provide serial numbers by say year or how to ID year I have a 
refurbished HQ-129X (none of the mods mentioned by KM1H installed) that 
works great. I would like to find out how old this unit is. I listened to 
PY's on 10 recently and yes they were not as strong as my ricebox.  I put it 
on 29Mcs for AM but  no Brazil but did hear a XE and a YV1.  The YV was loud 
with the Palomar pre-amp.

I tried a Central Electronics Model A slicer and did not like the results 
and may hook up a HC-10 to it later.  Seems stable enough for the HC-10.
