[Elecraft] K3 programming error or omission?

[tomb18 at videotron.ca]

Hello,I am attempting to program the threshold values in the Text decode seeings.
Using the K3 utility command tester, I issue the following commands:
SWH40; //select text decode - works as expected
DS; returns the expected VFO A text. For example if the threshold is at 11 I get DSTKR@@11@\xA0\x80;


I then issue an UP; of a DN; and the value never changes. Based on all of the menu items which work this way, I would expect the threshold value to change but nothing happens.


Is this a bug, or an omission, or am I doing something incorrectly?
Thanks for your help.
