While operating my 6400M in rig mode, when I push in the Mic/Speed PWR knob to access the Tx Menu, nothing happens. According to pg 145, it should bring up the Tx MENU. It has the latest s/w. Any suggestions?
Turned out that the outer knob was too close to the inner. I removed the rubber ring from the knob & loosened the hex set screw & moved it out a touch. Apparently,
the detent happens before the electrical connection. Not sure that is
the best way to design the switch. Ideally you'd want the detent feel
& switch make up to happen at very nearly the same moment. A nice 6
Sigma design project for that manufacturer.
Anyway the TX MENU now works. Simple fix & thank you Dudley at Flex for the suggestion. 73 Bob W8RMV
