KX2 latest beta FW? (and spkr issue)

[Steve Sergeant]

I haven't seen much (if any) discussion about the latest KX2 beta
firmware (MCU 2.77 / DSP 1.50, May 26, 2017).

I generally don't try beta firmware unless I have a surplus device to
try it on (or unless I really don't care if device I'm trying on works).

Who else, outside of Elecraft employees, is running it? Have you noticed
any stability issues?

-----
As a side note, I thought I had somehow blown my KX2 speaker by
accidentally turning off the AGC. So I just switched to earbuds and
didn't mess with it for a month. Then I got brave and set out to remove
the speaker from the KX2 bottom plate.

After removing the bottom plate from the KX2, and before removing the
speaker, I saw something shiny between the grille and the cone. It was a
single whisker-strand from the 26ga copper-clad I use for my portable
wire antenna. It was completing a magnetic circuit between the voicecoil
spool and the chassis sheet metal. After some very patient work with
tweezers, it was removed and my speaker was fixed.

I recommend that Elecraft glue a layer of fine mesh fabric to the inside
of the sheet metal to protect the speaker from this kind of dirt.

Actually, the latest beta is 2.79, it just has not been made public yet. From a post by Wayne on the 9th:


KX2 firmware rev. 2.79 has several minor improvements, including:

- CW sidetone volume can be set much lower

- Auto-power-off timer range is now 5 to 100 minutes (was 3-20 minutes)

- Filter bandwidth settings modified to prevent degradation of opposite sideband suppression

All of these changes will also be made to the KX3’s firmware next week.

If you have a KX2 and would be interested in testing the new release, please email me directly.
