[Hammarlund] HQ-170a intermittent RX problem on certain bands <100kc calibrator>

[Mike & Coreen Smith]

Hi and Thanks Glen,

It's been literally decades since I owned (well, used at least) a boat 
anchor w/ a Xtal Cal. but that's how I thought it must work.
I appreciate your confirmation of my thoughts.

This one is definately fubared in that respect then.  Fourty Meters nearly 
pins the meter on the scale. EU BCB stns are all quite loud, as are domestic 
CW signals.

Most other bands barely even move the S-Meter and 6m does not, thought it 
does "work" on 6.(barely, hi)
15m is dead as a nit. No detectable signals of any kind there 
whatsoever.--though I 'thought' I heard the xtal cal signal there one time 
just as I turned the rig on from cold.......now I am doubting my own memory 
as I only heard it the once.....hmmm, was the band switch on 20m.....hi 
hi.....lovely to get old and forgetful, eh?!

One of the guys @ work has a tube tester he's going to loan me, so I'll get 
checking, but I fear something more serious---at least when it comes to 6m. 
I'll be on the prowl for my own tube tester after prelim checks as I also 
have a set of Heathkit mobile twins needing some work. 
(Cheyenne/Comanche).......then there's the large Victor 1930's tombstone 
radio my wife has been bugging me about for about 20 yrs that I should do 
something with !

Cheers/73

  As for the signal strength of the calibrator:  Since you are starting with 
a 100 kHz signal as you go higher in frequency the number of the harmonic 
increases and with each increase in the harmonic number the signal strength 
definitely goes down.

  It is not unusual for the "S" meter to almost "pin" on 160 meters and 80 
meters and barely move at 10 meters or 6 meters.

  Let me ask this:
  Using the 100kc Xtal calibrator as an internal signal source, should the 
signal be gradually weaker as I move up in frequency?

  On 40m it's nearly full scale, but all other bands are very low. (most 
around s1-s3 or so......no visible S-meter reading on 6m however) On 15m 
there is NO xtal cal signal at all, nor any from an external sig gen.
