Thanks for these tips! I tried putting a cap in series with the probe and it seemed to improve but what I ended up trying was using my oscilloscope probe and I was then able to adjust pin 8 to 10.24001MHz within the +/- 20Hz. The funny thing was that if I connected the ground lead to the probe...

Yes the radio is set for 13.8V and the VCO is set to 2.5VDC with the PCB Jumper removed from TP7, TP8 & TP9. I'll try this tomorrow! Thanks!

I will try it with a 20PF cap on the probe, THANKS!

I worked as an electronics technician for 32 years but that was not with RF. I'm familiar with audio frequency but not radio. I believe I have the necessary test equipment and as far as my new frequency counter it read properly initially, although it wasn't dead nuts at 10.2400 MHz like the...

I am technically capable but don't really have a clue about working on these CB radios. I wanted my radios to be in perfect operating condition so I decided to check out if anything was out of adjustment because I wasn't getting any responses from anyone and reception was very poor. I faithfully...

I have the same problem and replaced VC1 but no luck. Can only get up to 10.2351 on pin 8 of IC3. I have a new X1 ordered and hope that is the problem.

If you're looking down at the chip and the Trimmer Cap VC1 is above it, Pin 8 of IC3 is the second pin of the top row counting from the left.

Can anyone recommend a good budget-friendly frequency counter that I can pick up to do CB alignments?

I am an old CB veteran from the late 60's & 70's who dropped out of usage for many years but getting back into it again.
