K3 Tuning Rates

There are four tuning rates (Hz per knob revolution) accessible by front panel buttons.  Let’s refer to them as R1-R4.  The rates may be accessed by the following buttons and actions:

R1       Tap FINE for a display resolution of 0.001

R2       Tap FINE for a display resolution of 0.01 or RATE for 0.01

R3       Tap RATE for a display resolution of 0.1 or hold COARSE for 0.01

R4       Hold COARSE for a display resolution of 0.1

The CONFIG: VFO CRS, CTS, and FST menu settings determine the combination of rates for R1-R4 according to the following scheme:

R1       CTS in Hz

R2       10X CTS

R3       20X CTS when FST = 20

            50X CTS when FST = 50

R4       50kHz when CRS = 0.5

            100kHz when CRS = 1.0

In tabular form, it looks like this:

CTS >>		100	200	400
FST	CRS
20	0.5	100, 1K, 2K, 50K	200, 2K, 4K, 50K	400, 4K, 8K, 50K
20	1.5	100, 1K, 2K, 100K	200, 2K, 4K, 100K	400, 4K, 8K, 100K
50	0.5	100, 1K, 5K, 50K	200, 2K, 10K, 50K	400, 4K, 20K, 50K
50	1.5	100, 1K, 5K, 100K	200, 2K, 10K, 100K	400, 4K, 20K, 100K
