[Elecraft] K3 Beta firmware rev. 2.63: Switch-press tones

[wayne burdick]

K3 beta-test firmware revision 2.63 (with DSP rev 1.95) is now 
available. Please send any problem reports to k3support at elecraft.com. 
For instructions on how to load beta firmware, please see:

Highlights:

* Audio tones on switch press (if CONFIG:SW TONE is set to ON)

* 1 kHz AM COARSE VFO TUNING RANGE ADDED

* Many new remote-control commands for use by PC software applications

Full details appear below.

MCU 2.63 / DSP 1.95, 11-04-2008

* SWITCH TONES NOW AVAILABLE: If CONFIG:SW TONE is set to ON, tapping
or holding switches produces audio tones corresponding to the switch 
state. This
supplements the normal tactile feedback of the switches.

* NORM SWITCH ALLOWED DURING TX: The “NORM” switch function (receive
passband normalization, e.g. 400 Hz in CW mode) can now be accessed 
during
transmit. It takes effect after the K3 returns to receive mode. This is 
especially useful for CW contest operation.

* COMPRESSION RANGE: Some operators asked for a higher “CMP” (speech
compression) setting to add “punch” under certain conditions. It can 
now be
set from 0-40. We still recommend lower settings (0-20) for normal 
operation.

* AM COARSE VFO TUNING RATES: Now 1, 5, 9, and 10 kHz.

* AM TRANSMIT: CONFIG:TXG VCE no longer affects AM transmit.

* SPLIT COMBINATIONS AVAILABLE: Cross-mode SPLIT operation is possible
with any combination of CW and SSB for VFO A and B. Same-mode SPLIT is
possible in all modes except PSK-D.

* CROSS-MODE SPLIT INDICATION: If you turn on SPLIT with VFO A and B in
different legal modes (e.g. CW and SSB), the K3 will remind you of
VFO B’s mode by flashing it (as well as the VFO B TX arrow). This 
reminder
can be cancelled by tapping any switch, key, or PTT. The reason for the
“reminder” is that operators usually enter cross-mode split by 
accident. If so,
cancel the reminder flash, then use BSET to change VFO B’s mode, or tap
A>B to copy mode A to mode B.

For software developers:

* “FW$” ADDED (direct sub/VFO B filter bandwidth).

* “SM$” ADDED (direct sub-receiver S-meter read).

* "DV" (DIVERSITY) COMMAND:  DV0 (off), DV1 (on). Also turns sub 
off/on. To turn
on the sub but not diversity, use an “SWT” command (verify SUB status 
with “DS”).

* COMMANDS AVAILBLE DURING BSET: "IF", "FA", "FB", "MD”, “MD$", and "DT"
(GET only). “FW” and “FW$” work in BSET except during diversity (TBD).
