Re: [Drakelist] Drakelist Digest, Vol 67, Issue 1

Hello Demis,

you may want to try reseating the DR7 first. I would say that EXACTLY 2 
MHz offset indicate a digital problem. The relevant circuitry sits on 
the DR7. The connector is on the upper left when the front looks to you, 
9 Pins. If you have an intermittent there, it could cause the problem 
you described. A little bit of Deoxit may help prevent further contact 
issues.


As always... whenever there is something strange happening on a TR7 or 
R7, reseat the boards first before you do any alignment.

Hi All,
I've problem with my R7A, this morning during a QSO at 14,222, the
reception frequency jumped directly to 12,222 for a few seconds to
return
to 14,222. I tried to rotate the band switch, the up and down
buttons, but
occasionally the frequency jumps. Where's the problem?

Do you have a solution to this problem?

Many thanks for possible help.

Hello Demis,

Guess the PLL needs adjustment, check the procedure in the service
manual. I had something similar in my TR7 which was solved that way.

[Drakelist] Drake R-4C Problem

[Dale Parfitt]

I have a nice R-4C that has an issue I have never seen before. The AGC only 
functions in Slow mode. The AGC switch checks out as  does the Function switch. 
A previous owner had jumbled the wires to the AGC switch (probably trying to 
fix the problem)- I am close to 100% sure they are now correct- but the problem 
 persists. In all positions except Slow, the AGC voltage is high, around -75VDC 
 from memory and thus cuts off the stages controlled  by AGC. In Slow, the RX 
appears to function normally and S meter readings  are OK.

Anyone have a suggestion?

 

Tnx,

Dale W4OP
