Badgrrmmr Posted July 21, 2021 Report Share Posted July 21, 2021 As the title says, I'm getting a "if bw mismatch" error message. Is this something fixable on the units (mcr42s and mtp-40s)? Quote Link to comment Share on other sites More sharing options...
Steff Posted August 21, 2021 Report Share Posted August 21, 2021 Hi, did you get this probpem sorted. Have exactly the same problem on mine. The transmitter on powering on also says RFOFF and I can't seem to find a way to activate rf? Read somwhere to hold down Ch and Gain to toggle rf on and off but it does nothing on my unit.

Badgrrmmr Posted January 28 Author Report Share Posted January 28 So, it's that the frequency charts on the RX are different to the TX. The UPK mini allows you to change them so they line up. Not sure about the RFOFF error you're seeing. Quote Link to comment Share on other sites More sharing options...
