[Elecraft] K3 Beta Firmware Rev. 3.42: Works correctly with HRD

[Wayne Burdick]

K3 beta-test firmware revision 3.42 (with DSP rev. 2.37) is now  
available. It corrects a problem with CW keying (and possibly transmit  
in general) when using HRD (Ham Radio Deluxe) software. See release  
notes below.

Please send any problem reports to k3support at elecraft.com. Beta  
firmware load instructions can be found at

MCU 3.42 / DSP 2.37, 10-10-2009

* POLLING PROBLEM WITH HRD FIXED: With no sub receiver
installed, applications such as HRD (Ham Radio Deluxe)
were still able to continuously poll for the aux DSP
revision number, causing timeouts that could disrupt transmit.

* SQUELCH CAN BE SET FULLY CLOCKWISE: In some cases
rotating the squelch pot fully clockwise would open the squelch.
Full clockwise now closes squelch.
