[R-390] R391 tuning lock Keys

Fri, 22 Aug 2003 7:50:09 -0400

Peter, you may have the locking keys from the CU 286/FRR-33 coupler, they are approximately 3/4 inch shorter than the locking keys on the R-391. I'm new to this reflector but I think I'm correct. I have both the coupler and 391 and found that the coupler locking keys were shorter.
