[Drake] R-4B T-4XB

[Frank Kamp]

Your problem reminds me of one I had with an R4A and T4X.

As I recall they were off by about 1kc in transceive so I used them  
seperately for the longest time.

When I finally got tired of that, I spent about a weekend checking  
the rigs and finally found that the 5mhz crystal in the receiver was  
off be about 1kc.  I replaced the defective crystal and the setup  
worked properly after that.

You might check the frequency of your crystal.

Regards,
Frank Kamp
