[Elecraft] K3s RX & TX EQ... N/A

[Kevin, N4TT]

I have the proset-k2 running off the rear panel mic/phone jacks. It sounds
fine on mon (too mic shy to test on air) but I'd like to adjust the
equalizer settings for Rx and Tx to get a feel for them.

For RX, as an example, I press the 1 button and see 0.05 +0. When I try to
adjust the VFO to change that setting or any Rx and Tx equalizer setting I
hear a beep and see N/A.

Book says: N/A message (Not Applicable): The function you’re trying to use
does not apply in the present context.

I'm in LSB, test mode so I don't transmit. What step am I missing?
