[Elecraft] K-Pod MCU 1.09 'F3 Power Up' Question (RIT tunit)

[Cady, Fred]

I've done some more testing and it is interesting to see the tuning rate for the KPod RIT in comparison to the OFS RIT tuning knob.

The K3 OFS knob changes the RIT frequency at about 500 Hz/rev.

Normal KPod power-on, the KPod knob changes the RIT frequency at about 1 kHz/rev and when holding F3 to power on, 500 Hz/rev.


To see these rates you have to tune the knobs fairly slowly so an encoder pulse isn't missed.


Cheer and 73,

Fred KE7X

Hello Marty,

I don't remember seeing any response to your question so here is what I have found with my KPod:

The K3's tuning rate is determined by VFO CTS, FST and CRS and there are two fine rates (1 Hz and 10 Hz) and a course rate (100 Hz) depending on the FINE/COARSE switch.

So when my CTS is 200, the K3 tunes 200 Hz, 2 kHz and 10 kHz per revolution.

The normal power-on KPod tunes 100 Hz, 1 kHz, and 5 kHz per revolution.  (it divides by 2).

Holding F3 when power-on the KPod tunes 50 Hz, 500 Hz and 2.5 kHz per revolution (divide by 4).


Cheers,

Fred KE7X

I installed the latest K-Pod firmware - MCU 1.09.   The release notes state "Adds a power-on feature: if the F3 button is held during power up the K-Pod encoder uses a divide by 4 scaling factor."    I do not notice any difference when powering up holding the F3 button.

What is the 'F3' power-up supposed to do?  I thought it might address the 4X VFO knob speed difference between the K3 and the K-Pod (my K3s VFO is still 4X faster than the K-Pod).

Thanks.
