K3 BETA FIRMWARE RELEASE -- MCU Revision 2.00

K3 beta-test firmware revision 2.00 is now available. It includes one
new feature (transverter band data) and two improvements based on
feedback users sent us about revision 1.99. Full details appear below.

The use of beta-test firmware is encouraged, but optional. Please send
any problem reports to [hidden email].

For instructions on how to obtain and load beta firmware, please see:

MCU 2.00 / DSP 1.77, 6-6-08

BAND DATA FOR TRANSVERTERS: The BAND0-3 outputs on the 15-pin ACC
jack can now be used to control transverters as described in the
Owner’s Manual (revision C, page 18-19). To enable this feature, set
CONFIG:KIO3 to HF-TRN (which outputs band decode data for both HF and
transverter bands) or TRN (transverter band data only). The default is
NOR (HF band data only).

CW MODE SPEAKER ARTIFACT ELIMINATED: Some operators reported a periodic
burst of noise coming from the speaker when headphones were used in CW
mode. This has been corrected.

MIC BUTTON FUNCTIONS DEFAULT TO OFF:  There’s now a menu entry for
turning the mic up/down buttons on or off (CONFIG:MIC BTN). The default
is OFF, which makes these buttons inactive. You should turn it ON only
if you have a mic whose up/down buttons provide contact closures to
ground, with no resistors in series or in parallel (such as a Kenwood
MC-43). Some mics have internal resistors and are not compatible with
the K3’s up/down feature. If you try to use such a mic (by setting
CONFIG:MIC BTN to ON), VFO A may scan continuously.

Are the version numbers for the MCU, DSP, etc. revisions just
sequential (i.e. 2.00 followed 1.99), or does the change from "1" to
"2" signify anything?  I am assuming the former and not inferring any
major significance to the new MSB.

Yes.

Not really. It's a good estimate of the square root of my cumulative
hair loss over two years of intense firmware effort :)

Seriously, it's just an increment.

Just sequential in this case.
