[Elecraft] New K3 field-test firmware: new PSK63 mode; changes related to KAT500 & K3/0-mini

[Wayne Burdick]

Hi all,

An interim release of K3 firmware is available with the following changes:

* * *

K3 MCU 4.92 / DSP 2.83, 10-14-2014

* PSK63 MODE ADDED:  To select PSK31 or PSK63, first tap either end of the MODE switch to select DATA, then hold the DATA MD switch and use VFO A to select the desired PSK data rate.

* KAT500 POWER-ON MESSAGE SHOWN ON K3 DISPLAY: If a powered-off KAT500 is pulling the auxBus signal low when the K3 is first turned on, "TURN ON KAT500" is displayed. Previously this condition would lock up the K3 without explanation.

* K3/0-MINI TX NOISE REDUCTION:  Polling by Remote-Rig units is suspended during PTT or XMIT switch use to reduce a "ticking" noise heard in some cases. 

* * *

(Other changes were made to this release that have no effect on operation, but require full re-testing of the K3 in all modes.)

If you're interested in loading and testing this firmware, please contact me directly (not via a list posting).

Thanks,

Wayne
