    Just got a new SM-50 desk microphone. I plug microphone into 7300 and it works except I can't get the buttons on mic to change the frequency. Am I missing something in the settings of radio? I've jiggled connector and I don't think it's a loose connection. Any help would be appreciated.

    It's not a function I've ever used - will check on mine when I get down to the shack...

    I don't have a 7300, but if I am reading the manual correctly, the "Tuning Step" function needs to be turned ON for the push buttons to operate.

    I figured out my problem!...I had set the keyer to be the microphone buttons so it was disabling them on SSB for the channel changing. Thanks to all for looking!

    Clarification...the CW keyer I had set way back to be the mic buttons since I don't have a paddle.
