[Elecraft] [K3] SHIFT/WIDTH in DATA A mode

After a long pause I started to operate in PACTOR again. My K3 behaves
differently today compared to earlier firmware some years ago. Current FW is
MCU 05.14, FPF 01.19, DSP 02.83.

In DATA A mode:
(1) PITCH shows N/A, in contradiction to the user manual. Seems to be fixed
at 1500 Hz. That's fine with me, as I can adjust the mark/space tones in my
PACTOR modem accordingly.

(2) SHIFT/WIDTH controls are showing a strange behaviour:
Based on the green LEDs next to the 2 controls, only LO/HI CUT is available,
SHIFT/WIDTH is not. When moving LO/HI cut, filter graphic and VFO B display
are both indicating a LO/HI cut, but what effectively happens is a width
variation. Verification is easy: Acoustically or on the P3 display.

73, Markus HB9BRJ
