MCU 4.43 / DSP 2.73
- POWER CONTROL COMMAND WORKING WITH XVTRs:
The "PC" remote control command now works correctly with transverters.
For example you can send "PC150;" to set I.F. output to 1.5 mW. (This also applies to HF bands if CONFIG: KXV3 is set to TEST.) Note that the upper bound on power output level is specified per- transverter band using the CONFIG: XVn PWR menu entry.
Please review the K144XV manual when setting up the drive level for the internal 2-meter module.
- PRELIMINARY SUPPORT FOR "REMOTE-RIG" MODE (details TBD).
