Re: Raduino Code version

Finding the original version should not be a concern.   Allard's goal is to keep original function to all his revisions, meaning they work on All

Bitx Radios.

So, just pick one version and go!  Probably the latest?

Pots

Looking for 10-turn pots, I discovered there were 3 1/2 turn pots. Anyone tried these? Should be able to spread the whole band over that comfortably.
Not trying myself - I'll be getting a 10-turn. I have one in another project - a 2m FM Rx kit. The L-C oscillator in that is not very stable, so I've considered scrapping it to recover the pot. It has a counting knob which is useless for the B40 with Raduino, and I've managed to calibrate knob count versus frequency (within cooee), so maybe it's better off as is. A new pot is not too expensive - unless buying from Element 14. $NZ300 for ONE! I think not! Ebay for that, methinks. I also see there's a 12-turn with shaft like the supplied Volume pot. The body of that looks less rotund but longer - might fit better for some? Not urgent anyway - need a new Raduino first.

Meanwhile, lurking ...

Re: Pots

 

IMHO,

The 10T pot works well for analog VFO but will be too slow for the raduino. I got used to it in a couple of days anyways!

Thanks for that, Raj. Any other comments? Anyone tried 3.5-turn? How do they compare empirically, degrees rotation per step delta-f? 10-t slow, is 3.5-t fiddly?

Re: Pots

The default tuning range is 50 kHz for a one turn pot. In that case you
will have 50 kHz/360 degrees = 139 Hz/degree (which is quite fiddly
i.m.o.)

In my raduino sketch you can set the tuning range to a larger value
(SETTINGS menu).
With a 10 turn pot you could use a tuning range of say 200 kHz. This
results in 200/10x360 = 55 Hz/degree, which is less fiddly. If that is
still too fiddly for you, you can reduce the tuning range to 150 kHz. It's
a matter of taste.

You could try different tuning range values for a 3.5 turn pot. I guess a
tuning range of about 75 kHz would yield comfortable tuning behaviour.

or look at www.rockby.com.au in Melbourne for far cheaper10-turn pots, Dex. I picked up two last week at a good price, from previous week's specials, accessed via the website.

Bill, VK7MX, off there on the smaller but historically more significant island to your left, facing north.

Re: Raduino Code version

 

The only “mod” you really need with Allards Raduino code is a momentary “Function” switch to
allow you to access the Setting Menu and use the features such as dual VFOs, RIT etc.

Details on wiring are in the documentation files with the code in GITHUB.

Other than that, it is completely backward compatible with Farhan’s original code.

Cheers

Re: Raduino Code version

I'd recommending adding that function switch mod, but you don't need it.

A stock Bitx40 radio has Farhan's code when shipped.
Upgrading to Allard's code without doing any hardware mods, it still has all of Farhan's original functionality.
But Allard's code fixes a number of issues.

I had that same concern and went the long way around the barn to get the original. It's not worth it. Get the latest and save  yourself a lot of time. It works well and allard has done an excellent job of change management which, imho, is hands down the hardest part if geekery

I agree with everyone else I originally was modifying the original code and learned a few tricks then I switched the allards code and am loving it! I'll probably be adding a agc and s meter to it and also personalizing it a bit more!

Re: Pots

Dexter N Muir
 

Be aware, Allard, that the 'one turn' is in reality approx. 270 deg. therefore 50,000/270 = 185 Hz/deg. Definitely fiddly - close to two 100Hz steps for one degree rotation - and a wire-wound pot is getting close to that 'resolution' per element winding! The kit supplies carbon pot, so that's not a worry - just a comment.
I'm more serious now about encoder tuning. I have one, and had it connected (I suspect it was that caused the banjax by exposed wiring), but never got to load code to activate it. I'll be a bit more careful with the new 'duino (Old saying: Electricity is a good servant but a *baaaad* master)! That'll be an adventure ... :). I'm considering using the old 'duino's Molex gear to plug/socket the Encoder. Waste not, want not.
BTW, there must have been a reason why the TUNE pot, pluggable for Analog, couldn't be a direct swap pluggable for use on the Raduino?

real men (and women) keep the tuning at the back panel and they tune with their toes.

Re: Pots

Jerry Gaffke
 

Very nice.
Rather like the "Main Tuning" and "Bandspread" knobs of receivers from 50 years ago.

For those still puzzling over Arv's ASCII art, there are two 10k pots shown on the left hand side
with no direct connection between them up through the middle.
So each of those 10k pots has one of the three pins left dangling without a connection.
The only connection between the two 10k pots is through the two wipers, which go off to the 1k pot.
The two 10k pots must be a single unit, driven by one knob.

Don't go cheap on that dual 10k pot.
All three pots should be linear, not logarithmic.
