Default R4-C dial calibration

Yea, I hate to admit it but bought the R4C from Radiomart. Had never
read anythig bad previously, til I started checking into him further.
The radio truly is in great cosmetic condition, little dust under the
hood, the bottom side of the chassis is clean. The radios main prob is
no ssb and the dial calibration way off. Martyn said to return it and
he would fix it. The more I find out, the less sure I am I even want
to send the radio back to him. It's a bigger waste to pay shipping back
to him and wonder if it will ever be right.

What's the consensus? I think I will take up the suggestion to send the
rig to Jeff Covelli and get it fixed right, and even though I will
spend more than I wanted to on the radio, at least it will be in good
working order and a keeper. The other alternative doesn't appeal to me.
What do ya think.? I sure wished I'd come here first...... guess your
never too old to make a mistake though-----Ted KQ4MZ

Hi all, got another Drake question. I got my R4C on Wed and it appears
to be in working condition but needs some work. It appears the freq
dial readout is off by about 65 khz. CAn anybody tell me how to align
the plastic freq dials so they correspond to the received freq? Is
there a way to crank the tuning dial all the way clockwise to the
bottom end of the band and realign the the 10 khz and 100 khz dialfaces
to 0 and 0? I took the tuning knob and skirt off but didn't have a pair
of split ring pliers to remove the split ring cliparound the tuning
dial shaft?. Am I completely off or is this an alignment problem. I was
told the alignment was well within specs.

Another problem appears to be the the R4C is only operating in AM mode
when I switch over to SSB the receiver mutes with no signal heard over
the speaker its like it is completely dead. Not sure what this could be
but makes the rig useless for SSB or CW monitoring. Again any thoughts
would be most appreciated I have no friends or elmers to help locally.
Thanks again. Ted---KQ4mz


Ted -

The Drake 4-line is now over 30 years old -- and requires proper maintenance
for reliable operation. Unfortunately many Drake items being sold on eBay
these days are either from estates or former CBers operators -- with had no
technical knowledge, BUT used golden screwdrivers on the equipment -- when
problems occurred.
I picked up a Drake R-4C from an estate earlier this year -- and I have
spent considerable time (2 months) cleaning and deodorizing this receiver
(former owner was a heavy smoker).

This R-4C now looks and smells like it should -- and will complete my work
this winter (minor issues - since this receiver was obviously used daily) --
before I send it to Jeff later this winter for a full alignment.

I would recommend sending your Drake R-4C to Jeff Covelli (WA8SAJ).

Pack the receiver well and enclose a list of all issues that you have
noticed so far.
After he address the repair issues -- ask him to perform a full alignment on
the receiver.
