[Elecraft] K2 - KDSP2 firmware version?

[Lyle Johnson]

KDSP2 has two firmware versions associated with it: the Control board 
(CTL) which interfaces internally to the auxbus of the radio, and the 
DSP, which interfaces only with the control board.

The latest versions are:

CTL 3.10
DSP 3.18

There are release notes or similar on the website about these -- perhaps 
in addenda to the K2 or KDSP2 manuals.  I don't have the information 
handy about what changed, but I think it had to do with rare instances 
of timing conflicts if you have the KNB2 installed and the KDSP2.   This 
was last changed several years ago.
