Yaesu FT-920 Frequency Error #29

The frequency returned from the FT-920 is scaled up by 25%. If the dial on the radio is set to say 10.000 MHz, flrig (and thus fldigi) will display 12.500 MHz. I've tried this on both a Raspberry Pi and a Macintosh. Both are similarly affected. This 25% scaling is actually in the flrig source code for that radio. The frequency read from the radio is multiplied by 1.25. I'm not sure why - maybe there are different revisions to the FT-920? In any case, this keeps flrig from working properly for that radio.
