I've just released raduino_v1.18, download it from

New in this release:

• improved CW performance at higher CW speeds:
  - reduced the delay at the start of CW transmissions (first dit is no longer lost at high speed CW)
  - optimized timings so that 1:3 CW-ratio is kept even at high CW speed
• improved FINE TUNE mode so that exact frequency (at 1 Hz precision) is displayed while the SPOT button is held pressed
• added an extra option in the SETTINGS menu for setting semiQSK ON or OFF.
  This may be useful for CW operators who want to manually activate the PTT (e.g. using a foot switch).
  - if semiQSK is ON:
  ???? radio will automatically switch to CWL (or CWU), and go into TX mode when the morse key goes down
  ???? go back to RX automatically when the QSKdelay time is exceeded
  ???? radio will switch back to LSB (or USB) when the operator presses the PTT switch
  - if semiQSK is OFF:
  ???? operator must activate PTT manually to move the radio in TX
  ???? pressing the PTT does not affect the mode. Use the Function Button to select the desired mode (LSB-USB-CWL-CWU)

• corrected a bug that FINE TUNE was not properly applied in USB mode

Happy BitX-ing!

Can we add fine tune as a option that can turn on and off in the normal mode settings w/o the "tune" button? I also noted in my Bitx I am about 45Hz off so I either get 40 or 50Hz I can't fine tune the radio settings. I hope its not a lot to ask and only wish I knew enough to help.

? Thanks for the great work I will be park ops in a few mins here on 7.277 I hope I can make it out barefoot.

Hi David,

you mentioned your BitX is 45Hz off, did the calibration procedure not
work for you?
Or do you mean that the 10Hz precision of calibration procedure is not
sufficient? Calibration currently works in steps of 10 Hz (at the time I
assumed this is sufficient precision), but perhaps we should change the
step size of the cal procedure to 1 Hz for even more accuracy?)

Yes the setting at 40Hz is off a bit and same with 50Hz it seems like if i could find a middle ground all would be spot on.

I am new to the raduino and arduino programming.? I have installed the 1.8.3 version of the ide, and have successfully compiled some of the simple examples on an Arduino Uno that I borrowed from my wife.?
I don't know how to handle installing the v1.18 in my Bitx40 raduino, when I tried to simply compile/verify, I get an error message about too many decimal points.

Some basic instruction please or a link for me to study would be greatly appreciated!

Dave, KI4PSR

A good how-to for upgrading the Raduino firmware at ?

Thanks, that link was a great tip!? I was not using the download zip method, rather a copy link method.? After downloading the .zip file, extracting it and then selecting and loading the latest raduino 1.18 version, it compiled without errors.? I am very grateful for your quick help!

I don't know if it's the problem, but do you
have the Arduino Nano selected? Also, do you
have the Etherkit Si5351 library installed?

I don't have the BITX40 ready to go yet, but
I'm listening on 7277 KHz. I can hear a couple
of stations, but I haven't caught the call signs
yet.

Thanks for your reply Keith, yes to all of that.? My issue was not downloading the proper file to compile.? When I downloaded the .zip all went well. Al Duncan VE3RRD pointed me to the information that helped me:
I had a good contact with VE3THR last night, great fun!

Dave, KI4PSR

Thank you, Allard, this works flawlessly.

Hi guys, I have my Bitx40 built and receiving. ?For some reason I think the final got whacked or it was shipped with a defective final so I have a few of those coming in. ?To date, mine has never transmitted but everyone seems to think that the new final will fix the issue. ?Let's hope.

To get back on topic my radio has the factory default firmware in it, something like 1.0 or 1.1, I don't have it here with me at the moment. ?If I install the new 1.18 firmware does anything need else added to the radio like the two switches to control the galloping VFO? ?So far I haven't added those yet but the switches are in the mail. ?I'm not going to be using my radio for CW so what's happened in the firmware between 1.0/1.1 that I will benefit from? ?Also, is there a place that I can get the original firmware in case I need to go back to that?

Thanks,

Curt

Curt even if you don't plan do do CW there are some nice improvements in Allard's code that are beneficial for SSB.?

The README.md file gives the details of all of the changes :



Minimally you need a FUNCTION button.

Just a few things that you might find useful :

- better tuning stability (less flutter)?
- dual VFO?
- Support for USB?
- support for 10 turn pot for tuning (tuning range setting in settings menu)
- ability to calibrate both LSB/USB from the settings menu?
- ability to adjust ?VFO drive level from settings menu (can help to reduce birdies)?
- with a SPOT switch closed you enter Fine Tune mode with 1Hz resolution (intended primarily for CW but also works for SSB)
- ability to work SPLIT (requires PTT Sense mod)
- decimal point for better frequency readability (i.e A 7.123.4 ?vs A 7.1234 )?
- disable tuning on RX with PTT Sense Mod (to prevent FM-ing during TX)

and probably a few others things that I have overlooked.

Cheers

Michael VE3WMB?

Whoops ... that last one should have read ?"disable tuning on TX" with PTT Sense mod to prevent FM-ing . !?

I had asked Allard and group the same question. Very recently I uploaded v1.17.1. I had the anti-gallop switches but removed them when I updated. I set my bitx to tune the entire band (no CW) occasionally I still hit the bottom of the 10 turn pot (yes you'll need one) the radio gallops. My buddy kept his in and his doesn't gallop, but I seem to remember that it doesn't maintain the last freq set before we turn it off. You will need one of the push buttons for a function switch (orange to ground) and a 10k resistor soldered to the main board and in the black position of the Arduino 8 pin plug for PTT sense whick will prevent FMing. I'll send you the wiring photos.
