[Elecraft] Fw: K3 APF Problem

[Jim Harris]

Vic,

As you suspected the problem with the menu misalignment was the front panel firmware revision.  Somehow yesterday when I had the utility download all the latest firmware it downloaded 1.09.  Today it found 1.14.  I've installed it and the menu problem is resolved.  Strange how it found the right one today but not yesterday.

However, function of the APF is unchanged from what I've described below.  That is a loud clip when engaged, CW disappears and then when rotating the shift control there is a loud clip when each 50 Hz step is incremented.  I've read the manual to no help.  Any clues from anyone would be helpful and appreciated.

Vic,

Thank you for the response.  You may be heading me in the right direction.  I had the K3 Utility download the latest of all the firmware's from the website and told it to install them.  It shows it downloaded and installed FPF 1.09.  You mention it should be 1.14.  I'll try to find it on the site, download and install it and see what happens.

Strange that what should apparently be the latest release is not directly available when the Utility checks the website.  That creates problems for people like me.

I'll post results when there is something new.

Take pride in the USA. 73

Make sure that the front panel code is also updated. The proper version for 4.25 is 1.14. 
Also make sure the proper DSP table is present when you update; it should be DTBL0014.HEX. 
If all the versions aren't synchronized you can have problems like you describe.
