MCU 2.10 / DSP 1.81, 6-22-08
* SYNTHESIZER: Tuning and band-change improvements (prevents ERR PL1,
etc.).
* NARROW FILTERS IMPROVED: Gain balanced for "FIR" filters (CW and data
modes).
* NOISE BLANKER can now be used with AGC turned off.
* DENOISER (NR): Gain balance improved in SSB and AM modes.
* EXT ALC voltages adjusted to match resistors called out in EXT ALC
mod document
(on the K3 mods page).
* TX/RX switching time improvement in DATA-S mode ("SYNC Data", for
AMTOR, etc.).
PC Control Command Changes (for application software developers):
* "PC" (PWR READ) IN K22 MODE now supplies correct value for QRO (KPA3)
on/off.
* “FA/FB” BAND CHANGE now saves mode for old band before switching to
new band.
This prevents problems with per-mode bandwidth, etc., following band
changes.
* “MD” COMMAND FIXED: On 6 m, CW norm/reverse were being reported
backwards.
On all bands, DATA A and PSK-D were reversed for both get and set
(AFSK A and
FSK-D were correct). NOTES: When an “MD” command is used to switch
between
data normal and reverse, it applies to both DATA A and PSK-D (if
either of these was
in effect), or AFSK A and FSK-D (if either of these was in effect).
NOTE: An extension to the "MD" command is in the works to directly
get/set K3 data modes.
Meanwhile, you can use “SWH43;” to emulate pressing the DATA MD
switch, then “DB”
to retrieve the data mode text string from VFO B, and “UPB;” / “DNB;”
to change the mode.
