Please update your K3 firmware to MCU revision 1.55, especially if you
use data modes. This revision includes major changes to DATA A (generic
data mode) and AFSK A (RTTY-optimized data mode), as well as other
changes affecting all data modes. Just in time for the RTTY Roundup :)
MCU 1.55, 12-28-07
* DATA A and AFSK A work correctly in both normal and reverse modes.
* Power control improved in DATA A and AFSK A modes.
* CMP (compression) is automatically set to 0 in all DATA modes.
* DATA monitor level is now set correctly on power-up. It's separate
from voice monitor level.
* SHIFT RANGE in DATA A mode is same as USB/LSB. Had been constrained
to +/- 500 Hz.
NOTE: SHIFT range in dedicated RTTY modes (AFSK A & FSK D) depends
on PITCH selection.
* ALC/CMP metering automatically disabled in FSK D/PSK D modes.
NOTE: I recommend that you use the latest version of our firmware
download program (K3 Utility).
