Hey Gang,
Is anyone operating your k2 with a 750Hz sidetone?
If so, what do you have as your BF1,BF2,BF3,BF4 setting values?
And how do you get the unit to save new values!!!

I'm thinking my unit has a problem as it seems to be refusing to accept
BFO changes.

For example right now BF4 is set to 075c
I want to change it to 072c
I adjust it to 072c and then per the manual I press MENU, or XFIL or
AGC.
It doesn't matter what I press, the unit will go right back to the BF4
075c setting. 

I'm either stupid or the rig has a problem!!
