Was this useful?

FM MODE SELECTION AF ARTIFACT: Eliminated.
RECEIVE AUDIO LOST ON BAND CHANGE: Fixed, probably. We were not able to duplicate this, but we may have eliminated the cause.
KXBC3 TIME-SET ERROR (etc.): Fixed. In very rare cases, KX3s were unable to communicate with the KXBC3 module.
XVTR BAND DISPLAY FIXED for cases where 100s of MHz digits are 00 (e.g., RF band = 3400 MHz).
SIDETONE MAX VOLUME SETTING INCREASED to 40. Note: This is a very high level. We increased it to support those with hearing loss or very inefficient headphones. Most operators will use settings in the 1 to 20 range.
RIT/XIT NEVER LOCKED: VFO lock now only applies to the VFO, not RIT or XIT.
