KD8CEC 2.0, Nextion Screens,? and open source uBITX Raduino boards for Arduino IOT, BLE, RP2040, Teensy 4.0, and Raspberry Pi Pico

Is there a version of the firmware that will work with FLDIGI's cat keying option? I'm Using N8ME's version and while ptt activates, no code is transmitted.? I've tried both RIGCAT and HAMLIB set up for the FT817.
Thanks for any help.

That is a bad BFO number for any version of the uBITX. And that Master Cal doesn't look right either. I am sure you saw the warnings in the log on the right. (Note there is known bug that saws V3/V4/V5 in one warning - That is a typo (and fixed on github) ans should red V3/V4)

The SE talks to the uBITX (using the CAT protocol) to read the EEPROM. The uBITX then performs a fresh read at this point. So on *startup* the SE is reading the raw data from the EEPROM.

However, if it asks for an update (perhaps you changed the cal number in the SE and have not written it), it gets the current calibration number being used by the radio and? that *might not reflect what is in the eeprom*. This is how the "Calibration Wizard" works (if you had V2 installed. You can adjust the calibration, and see it change in the sound generated, but until you write that number, it is never saved in the EEPROM.

Dr. Lee suggested that you might use the original Memory Manager? by:
1. Measuring freq of TX or BFO
2. Adjust in MM
3. Write to EEPROM and reboot the uBITX
4. Repeat 1-3 until you get satisfactory results.?

You can do this with the SE too.


One of the secret "features" of KD8CEC is that when it finds a bad BFO number, it chooses a typical value *silently*. This number is based on whether you have installed KD8CEC for V5 or V3,V4. This code is in ubitx20.ino and should be something like this in V1.2 (I modified it for new #defines in V2, so look for the numbers)

I hear ya, Ian.? So far, everything I've monitored has been USB.?

? ?Looking at the range of certified radios, it seems that unlike VHF, HF SSB 'channels' are just a random suggestion. They vary from manufacturer to manufacturer, and from generation to generation from the same company.?

? ?I use the TSW Teensy 4.1 Raduino and would like more than the 10 memory locations in the current software if possible.? As a retired SIGINTer, I'd rather see the frequency than something like '77' or '41A' anyway.

? This might be fun!

Thank you, it is really neat

No 1. : After cold start up there is no RX. I have to closedown the sbitx app and restart it to get RX signal.?

Yeah I'm interested that thing looks sweet. With the side rails and flat black color it has a tactical look to it.?
On my recumbent trike I have a ammo can that I converted into a trunk. I painted it with some spray on truck bed liner. The stuff is a lot tougher than paint and if I had metal working skills good enough to make a metal enclosure, I think that a couple of coats of bed liner would be good for a portable rig.?

I have attached a zip with the 3-d printed parts.

Today, after soldering on a really nice long cable between the two UARTs, so that I now have a fully functional CAT cable between computer and sBitx (DE) I tested the WINLINK server software RMS TRIMODE.? ?This is the software that scans typically five frequencies one after another, 24/7/365, on about 5 second intervals.? ?This is in use at hundreds of volunteer stations worldwide that provide gateway and other services all day every day.

It works!? ?However, I did experience some frustration with having to "sequence" getting programs turned on in some order and having baud rates set properly and such.? ?At this point, the software is quite primitive and doesn't handle those kinds of annoyances very well (and I'm NOT a truly qualified software designer!)? ?However, it does work.??

1.? Sbitx has to be started first.
2.? The the ICOM Emulator software (which now has an Icon!)
3.? This computer had been used with a TI calculator and loaned out to a student and used for conference viewing...and for some reason it said almost all com ports were already assigned.? ?I ended up having to reboot the computer to get it to act more "normally"
4.? ?Furthermore, the sBitx end (the radio has been ON for a long time) chose to assign "/dev/ttyUSB1" to the device -- my software doesn't gracefully handle that, it just quits!? ?Duh.? ?

So this is very very primitive.? ?But now I have demonstrated successful working with the Winlink Client, the Winlink Server, and the ALE (ION2G) Client.? ?Those are pieces of software that emcomm folks in the state of Florida are familiar with and would NEED to have working.? ? So pleased to at least get this far!

Back to work,? Slides are flowing rapidly for the.upcoming talk on the sBitx?

My information is good at QRZ. I will check out your suggestions today and get back to you.

Thanks for the interest Mike.? I don't have a paypal account.? You have my email address and there are a few apps that offer free services.? Quicken states Venmo is best after?
paypal and Google Pay might work as I have a Google acct.? ?If out of USA Remitly is supposed to be best.? I am sure $ 20 will cover shipping,if within the USA.? ?When you choose the service, send $150 and I will take care of the rest!? If out of USA, let me know where to ship, so I may calculate shipping.?
Thanks

Has anyone else made their own enclosure for their sBITX?
If so could you post some pics? I can't be the only one wanting to see what others have done.?

Good point Gyula.
It's nice to catch this now than at a park lol.?
I couldn't find the amp draw on my RPI touch display so I'm assuming that it will be less than the 15" laptop screen. I can run tests on different displays and different batteries to see if I can find a workable solution. I would rather have a smaller screen than a dead battery.?

Which fault are you experiencing Harald??

1) Pause required before sBitx application started after start up of the Pi
2) FT8 doesn't switch back to RX correctly sometimes
3) Low power output

uBitx Manager automatically shows me the correct master_calibration.. This is what I got entered when I turned the knob to 32 (Zero Beat)

If uBitx Manager is able to read the master calibration correctly, why do I still have to write it?

?

Yes just change the low pass filters AND you need USB even on the low bands 2 & 4 MHz. It would be worth adding "channels" to the software

ps.: I think you are using something like this to .
According to the description, 12V 3A is required for the supply voltage.
It consumes quite a lot, it is not a portable version or it works well from a car battery :-)

Aaron,
I understand. This way, the position of the girl is completely different when you use the laptop display as an independent unit.
I also have an old laptop display, I'm still trying to figure out how I could use it for this purpose.
The sBitx motherboard has only one 12V connection point.
Make sure that there is a thin line plus sign on the top side of the pcb, but this is not the marking of the positive pole, but a positioning cross!
So it's not the input positive.
