[Elecraft] New K3 Firmware Release -- Major Improvements to DATA Modes

[wayne burdick]

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).

73,
