[Drakelist] TR7 Questions

[Don Cunningham]

I fully realize that many "guru's" may be at, or heading to, Dayton, but I 
want to pose a couple of questions.  Yes, I bought a couple more TR7 
"orphans" over the past couple of months, and no, I didn't need them, hi. 
First, one I bought, a very nice, late serial numbered TR7 (loaded!!) puts 
out about 200w PEP on 160m.  I have not tried it on any other bands, but 
that seemed a bit high to me.  As soon as I get some mess cleaned off my 
bench, I'll try the dummy load and check it over all bands and report.  All 
else in this rig is near perfect, good audio reports, nice receive, etc.  I 
want to pair this with the R7 I have, the RV75 and try building up Lee's 
rigging to connect the three.  Second rig, 75xx serial number, has several 
problems (other than filthy, hi), but some of them may be related.  It has 
the "pinched audio" symptom typical of one needing the passband adjustment. 
When I go to put the rig in general coverage to get to the adjustment freqs, 
the up/down buttons will not move the freq up and down in 500 cycle ranges 
like it should.  Also, random segments will not light up on the readouts.  I 
first thought it was bad readouts, but the segment will light in some digits 
and not in others where it should be present.  I have to dig out my service 
manual, but it seems that both of these problems might be located on the 
DR7.  If so, I may be able to swap in a good, known DR7 I have and fix most 
of this one by that swap.  I do have readouts, thanks to John Loughmiller 
years ago, but don't really think that's the problem.  I also have the 
pushbutton assembly I bought before Drake sold out of parts.  All the "other 
buttons" on that assembly work fine, so I doubt that is the problem.  Any 
thoughts from this rambling from any of you that didn't get to go to Dayton 
like me??  Also, are any of  you as mesmerized by the EVA's the astronauts 
are doing on Hubble???   Unbelievable video on NASA channel!!!!  Voyager, 
with ancient SSTV, was fun in the 70's, but this takes the cake for exciting 
for me.
73,
Don, WB5HAK
