[Elecraft] re audio distortion when using auto notch on K3

[Don Wilhelm]

Fern,

General instructions to upgrade the firmware are in the manual on page 42.

The procedure is to connect the K3 to a computer serial port;
Download the K3 Utility application from the Elecraft website;
Tell K3 Utility which folder on the local computer should be used for 
the download files;
Connect to the internet and click the button in K3 Utility that says 
something like "Check for New files"; K3 Utiity will download the files;
Once the files have been downloaded check the boxes for the firmware 
versions that are to be loaded to the K3 and then click on 'Load data 
files' (close but may not be exact words).

That is all there is to it - K3 Utility does most of the work.

73,
Don W3FPR

This will happen on signals S9 and stronger. He thinks that the radio has firmware 1.73 but couldn't figure out to bring it up. How does one bring up the firmware version?
