[Elecraft] K3 BETA FIRMWARE RELEASE -- MCU Revision 2.00

[wayne burdick]

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 k3support at elecraft.com.

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.
