I am the proud owner of a Beltronics Pro RX65 (version 6.1) and I am having some trouble. When I go to program settings and go all the way to bands mod and cycle though X, K, KA, and so on I notice that if SWS is ON and I attempt to turn off K band it refuses to do so. I found this out by shutting off all other bands, POP, Laser, KU, and so on. However, when SWS is off the K band will stay set at ON or OFF depending on what I set it to. Is it a device malfunction or is supposed to do this and I just haven't noticed it yet? My gut is saying no it's not, but I need some back-up from all the experts and everybody to make sure it is not just me.
