Dynamic Fast-Slow Auto tune steps #R1CBU-Firmware


 

Hi Oleg,
I have a feature suggestion, I was wondering if it was possible to devise a fast slow dynamic tuning rate?

If you are on 10Hz and start to tune quickly it might step up to 100Hz then reduce back to 10Hz when the spinning slows down?

This is similar to the TECSUN PL-660 SW RX that has auto Slow/Fast tuning.?

For CW ops, it would be a massive help I think when you see a signal on the magnified spectrum but you are in 10HZ mode, it takes a long time to get top it without more button pressing.

I wonder if anyone else would like such a feature?
Thank you for you amazing work on this ?by the way, from one coder to another... it is very appreciated.

Yes, I know about such a function. I don't really like it, it doesn't always work predictably. Instead, I have other plans - I want to make detection and automatic “jumps” to the signals that are at the waterfall. This is mainly for blind users, but maybe someone else will find it convenient.

I believe you call it velocity tuning.? It would be a very top end feature.? What do you think Oleg?? You got my vote.? Lml

I don’t see any fundamental problems to implement this. I'll think about how this can be done beautifully


 

First time I saw that feature was back in the year 2000-2001, implemented in the Patcomm PC-500 QRP radios, by Patcomm Corp.
Those radios were ahead of its time indeed.

Sure helps.

Forgot to mention... It was called "Variable Speed Tuning" back then.
You had a button to turn it on and off, of course.
Cause as you approached to your target frequency, was better to turn it off to avoid overshoot your intended frequency.
The weighted tuning wheel was very sensitive though.
Nowadays, we do this via SDR, thus can be controlled way much better.

Oleg. Use base tuning step. If knob velocity is greater than x step time 10 or 100???? Nl7ln

Yes, that's understandable. I need to practically look at the rotation speed ranges and which multipliers are most convenient to use.


 

I had a Kenwood TS-50S and it used "fuzzy logic" to implement a similar feature.?
The faster you turned the encoder the larger the step. As you slowed down your tuning rate the step got smaller.

IMHO this is a very intuitive approach to tuning. It gets my vote !

That would be a good feature.? Some other rigs have this slow tuning and jump to quicker/faster tuning when rotate tuning knob fast.

I have always had issues with the X6100 tune, seems to slow in 10 Hz mode and cannot get on exact freq in 100 Hz tuning mode.? I find my self continuously going back and forth between the 2 tuning steps.

Eh, they convinced me... I did this with the settings. "None" acceleration, "Lite" acceleration x5, x10 and "Strong" acceleration x10, x30.
Will appear in the next release
