I just got my RX65 back from Beltronics last thursday. Have only had a couple of hits with it since i got it back. One tonight with a sheriff running Ka35.5 at a 1.7mile pickup. never had many 35.5 hits mostly 34.7. Seems to work on Ka but not good on K. I sent it in it was a version 6.1 now its a 6.2. seems t work good time will tell.
