Hi Steve, I've been away for awhile... happy to see you are still here; lots

Yea... halfbaked... you know me... remember that long thread years back
where we picked at the R8B? I still haven't changed my mind about it! My
R8B gets a serious workout; it's on everyday and sometimes all day too.
Over the years since I had it little glitches keep coming up. I've reached
the point where it might be a cheaper to trade it in on a new one instead of
sending it back to Drake for repair---labor was $70.00/hour a couple of
years ago, maybe more now. Besides, every time it comes back there is a new
ding here and there.
Problems I notice now is drifting of the notch, passband control has slowly
moved off center, some crystal must have drifted off frequency as I get a
beat when it should be zero beat in LSB and USB mode during exalted carrier
reception and a quirk that comes and goes---It take a couple of three
seconds to get audio after the receiver is turned on and sometimes I have to
crank the audio gain way up to get it to go. I just don't feel exicited
about trouble shooting it myself.
BTW, I guess it's been a year since I did a clean job on the
encoder/switch. Everything is running fine. I am really beginning to think
its the grease that the encoder/switch is packed with that is the problem
with the premature failing of the control that folks are experiencing---you
might have read my analysis a year ago. I cleaned mine with DeoxIT and
lightly lubed it with CaiLube---that's after I cleaned all the grease out of
it.
Best Regards,

My R8B has been quite reliable except for the notorious encoder wheel
too. I agree that the factory lube seems to be the problem. After
thoroughly cleaning it and relubing with 'Super-Lube' (a synthetic
grease) I've had no further problems with the encoder for over a year
now. Do you power your R8B with AC or DC? I use a 12-V regulated supply.
The radio is usually on all day and most of the evening. It runs quite
cool on DC. How old is yours? Mine was made in late 2000.
