K3 MCU 4.66 / DSP 2.81, 3-22-2013
* FSK-D KEYING BANDWIDTH GREATLY REDUCED: This change reduces the
amplitude of the FSK-D keying sidebands by 25-30 dB at a 500-Hz
offset, giving the K3 one of the cleanest FSK signals available.
* K3/0 (REMOTE-RIG) IMPROVEMENTS: (1) Supply voltage can go down to
7.6 V; (2) VFO lock works correctly; (3) TX LED no longer gets out of
sync.
* IMPROVED HANDLING OF SERIAL I/O (RS232) ERROR CONDITIONS.
* SUPPORT ADDED FOR ALTERNATIVE LCD DRIVER IC. This has no effect on
radio operation.
* RIT AND XIT NO LONGER TURNED OFF UNINTENTIONALLY: In previous
releases, changing bands via direct frequency entry (FREQ ENT) or
remote-control band change commands (FA, FB, and BN) would turn off
RIT and XIT. This was true even if CONFIG:SPLT SV was set to YES.
