K-Pod VFO counts per turn?

[Rick-2]

I wonder if there is a way to adjust the counts per turn for the K-Pod
VFO control?

The menu item "VFO CTS" allows one to adjust the counts per turn for the
K3's VFO, but I can't find a separate menu item for the K-Pod VFO
control. I have the K3 VFO set to 200 counts per turn, but it looks to
me like the VFO on my K-Pod is set to 100 counts per turn. Specifically,
a full turn of the main K3 VFO control changes the frequency by 2 KHz,
but a full turn of the K-Pod VFO control changes the frequency by 1 KHz.

I'd like them to be the same. I can accomplish that by changing VFO CTS
to 100, but I like the 200 setting better.

I've done some experimenting, and this is what I see:

I am using my K3 with firmware beta 5.50 along with my new K-Pod. I
noticed that the change per turn in VFO frequency is different between
the main knob and the K-Pod knob.
Specifically, I see the following behavior as a function VFO CTS setting:

VFO CTS setting    main/turn    K-Pod/turn
100                        1 KHz            0.5 KHz
200                        2 KHz            1 Khz
400                        4 KHz            2 KHz

So, it appears that the K-Pod knob changes the VFO frequency half as
fast as the main knob. I assume they are supposed to be the same. I sent
an email to Elecraft K3 support regarding this.

What are other K-Pod owners seeing?  The K-Pod uses the same 100-PPR quadrature optical encoder as the K3.  You should see 400 counts per revolution with VFO CTS set to 400.

With VFO CTS 100, I see 500 KHz change for one revolution on the K-Pod and a 1000 KHz change on VFO A

With VFO CTS 400. I see 2000 KHz change on the K-Pod and and 4000 KHz change on VFO A.

Both on 20 meters.

Thanks, Bill.  That's exactly what Rick is seeing.  The K-Pod is essentially functioning as a 50-PPR quadrature encoder, rather than a 100-PPR quadrature encoder.  Let's see what Elecraft has to say.

The K3 and K3S both use all 400 counts of the VFO A and B encoders (100 pulses/track/revolution).

The K-Pod defaults to 200 counts. During our testing we found that this provided the best compromise between precision and "fussiness" for typical K-Pod operations.

We plan to add a function to K-Pod Utility (which itself isn't quite ready yet) that will allow the user to change this to 100/200/400.

Thanks Wayne. So I understand what I'm seeing is correct, at least for
now. I'll watch for the new K3 utility.

Any update on this? I just got my k-pod and experience the same issue.
I would really like to have the same counts on the k-pod as the VFO on the
K3.
