Question on KDSP2

[Tom McCulloch]

I have a question on the KDSP2, the DSP filter for the K2

I have K2 firmware version 2.04P  installed in my K2, as shown when I press
any key on power up.  I also have KDSP2 firmware version 3.16 installed. as
shown on the display when entering the appropriate commands.

According to the KDSP2 Manual Errata (presently posted on the Elecraft web
site) I should be able to toggle the Autonotch and the Denoiser on and off
directly from the K2 front panel by simultaneously pressing and holding
AFIL+SPLIT and AFIL+REC, respectively.

When I do this I get a message on the LED "Not Installed" (appropriately
abbreviated, of course).

I am able to perform all of the other DSP functions except for these.

Can anyone tell me what I am doing wrong or how I can track down this
problem

Thanks in advance for your help

Tom,

My KDSP2 works as you described, however, my KDSP2 flash firmware
(first number shown) version is 3.18 and KDSP2 microcontroller
firmware second number shown) is 3.10

If I read the errata sheet correctly, you'll need the KDSP2
microcontroller firmware version (second number shown) 3.10 for the
short cuts to work.
