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.

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

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

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?

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.

Re: Pots

Thanks for that, Arv! and valid points from Jerry, too - fond memory of brief acquaintance with an Eddystone 640 :) Now to investigate the junkbox ... For *really* fine tuning, try taking the 10k dual to a 100k dual, and the 1k (now really fine) can then be what you have up to 10k (original effect). Ratio gives you the 'gearing'. Could be a bit of exposed wiring - bypass the 'fine' wiper?

Re: Pots

... and as 'top' of 'fine' pot goes to 5V, bottom goes away from GND. :)

Re: Pots

Arv Evans
 

Dexter

Yes, bypassing the fine adjust wiper could be a good idea.  I would start with a 0.1 mfd cap.
This could be used by those who cannot find a 10-turn pot, or just want to use the older
style fast & slow tuning mechanism.  It should work with any design that depends on variation
in DC voltage to control tuning changes.

The pot values are not critical.  The smaller pot tunes over a percentage of the larger pot range.
Using a linear pot would be preferred but a tapered type could also be used as long as both
halves of the dual one track reasonably well.  This can be mocked up using the pots and a DC
voltmeter to see how it works before you build it into your rig.

Re: New bitx40 build.

I decided to work on the rig a little rather than "stalk" the band tonight. Loaded Allard's 1.20.1 software. Wired out the function switch. Having A and B vfos is nice. It seems USB does not have as much band noise as LSB???? Hoping to get the CW mode working on the rig before long. I have yet to touch anything on the main board. It seems a shame for me to place my unsteady hands, gripping a heated instrument of potential destruction, on such a nice product that has been working so well, but in the spirit of adventure, and probably stupidity, this project must go forward.

Added a little  board to get all the grounds tied down. Added pins for the connection to D4, D5, D6 and D7 and a calibrate switch.

Hope you are back soon Paul. I'll miss your reliable signal.

Re: Pots

 

Dexter,

I have not tried the 3.5T. It may be fine for the analog VFO. The Raduino default jumps 100Hz and that is as fine as it gets,
no point in stretching it to a larger angle of the pot.

On the test bench the pot being loose I used a center indented 10K so that I can get the feel of the center. I am putting
a board in vu2pop box and once it is on the panel then indent wont be required as I can see the position.

I have been experimenting with limiting the tuning pot with 510-560 Ohms resistors at the extremes to stop the end fast tune
and would like to put a center off toggle switch that I can use to jump 10KHz up or down. Someone here has done that before.

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?
