[Elecraft] help with my rigs center frequency

[Richard Ferch]

You can change the filter centre frequency in any mode by using the 
SHIFT control. Tapping this control will switch between SHIFT/WIDTH and 
LO/HI CUT modes, and will also briefly display the current FC or LO 
setting in the VFO B display. The default or "normal" FC is marked with 
an asterisk (*).

The default filter centre frequencies in CW and in AFSK A/FSK D can be 
adjusted using the K3's PITCH control.

Assuming you are using sound card software for PSK31, you will likely be 
using DATA A mode. The default filter centre frequency in DATA A is 1500 
Hz. The PITCH control is not available in DATA A.

As a side comment, the SPOT control does produce a tone in DATA A, but 
the tone it produces is not at FC, it is at the CW sidetone pitch, which 
is irrelevant in DATA A.
