My V6 UI has suddenly started beeping with each button press.

Jeff Debes
 

Hi all,

My V6 version has suddenly started beeping when I touch UI buttons, it was not doing this before, it was silent on any button press .
Might I have changed a setting inadvertently?
I do not recall seeing any menu or setting for this change?

No, I have not read all of the documentation yet.
Just thought I’d ask if it is an unusual or known issue.

Jeff

Aaron:

Place all of the files you see from the download in the same directory. Indeed, they MUST all be in the same directory. Now load the IDE, move to the new project directory and double-click on ubitxv6.ino. The IDE will load all of the files into the IDE. The *.ino file is always the first one (left-most tab) in the Source Code Window. All of the other *.cpp and *.h files will appear in their own tabs across the top of the Source Code Window in alpha order:

Why didn't Reed just use one big INO file? The biggest win is that the Arduino compiler supports incremental compiles. In other words, if you're working on just 1 of the 60+ files and you recompile, the IDE compiler is smart enough to only recompile that particular file. The linker takes the other (cached) files and combines them into an executable for upload. On a project I worked on with 11000+ lines of code, the first compile in the morning took about 1 minute on a very fast machine, but subsequent recompiles were typically 10 seconds or less. If you save 50 seconds per compile and do 30 of those a day, that saves you 25 minutes of thumb-twiddling each day.

Long answer to a short question...

Thank you Jack,

I was looking at all of the files and was thinking, which one do I need or want.

I’m completely guessing here, do I add the sketches that Reed has to the existing default sketch in my Arduino Nano one at a time to see if I like the change in the performance?

The main entry point for any Arduino project is the file that contains setup() and loop(). The file that holds those two functions must have the secondary file name *.ino. For Reed's code, the file is ubitxv6.ino. The purpose of the setup() function is to establish the environment in which the code is to run. The purpose of loop() is to provide a continuously-running body of code and is the work horse for the program. I would start with setup() and then proceed to loop(), looking at the function calls in each. If you need help understanding the C code, I can give you a (very biased) book recommendation.

Re: Will this mic work?

Vince Vielhaber
 

TenTec puts 9vdc on pin 4 of the mic connector. Not having a schematic of the mic, you may need to put a DC blocking cap on pin 1 since the ubitx puts voltage there for a condenser mic. You'll need to supply your own 9vdc to pin 4 to run the mic. Looking at your first post again, I see that mic will take 7-14. Put a 560 ohm 1/4 watt resistor from your 12v supply to the 706's pin 4. That should power the mic.

Will it be too much audio? Don't know until you try it, but if it is you can add a pot to adjust it. I did that on a bitx40.

Re: Bitx V6 Modifications

Evan Hand
 

There is an RC combination (0.01 uf and 1.8 K) that you solder between pins 5 and 8 of the LM386.  It was listed as a BITX40 mod (that was the last HF Signals produced rig that used the LM386 until the v5 and then v6).  I tried the mod on my v5, and it did reduce the high-frequency noise.  Sounds much better without a signal present.  Reduces some need for the AGC, though still would add it. 

https://groups.io/g/BITX20/message/51572 was the starting point that lead me to the Norcal 40a http://www.n5dux.com/ham/files/pdf/NorCal%2040A%20Transceiver%20-%20Manual.pdf where I got the pin 5 to 8 connection.  There is a capacitor between 1 and 8 in the Norcal 40a the same as in the v5 and v6 audio amp stage.

Ignore the comment that it would not work on the uBiTx, that was before HF Signals went back to the LM386 as the audio output amp.

Re: What’s actually better?

Dennis Zabawa
 

This is the 'Achilles Heel' of the open source movement.  Each user is free to implement their own modifications based on their education, experience and biases.  Who is wrong? Who is right? Are they all right in their own way?  Deciding which path to follow is WAY too existential for me!


Nextion 3.2

John Veach <ke4d@...>
 

Got my firmware update  from KD8CEC webpage but the 3.2 display was actually only 2.4 or 2.8. Verified I had the correct file but still no good. Finally picked jo the file from files on this site that Alan had on board and bingo. It works as it should. Thanks Alan

Hi Dan, where are you going for instructions to install that AGC from kit-projects? Thanks

Alison and Farhan are to both very credible resources but they seem to contradict each other. I had planned to follow Alison’s advice and then saw what Farhan had written...

Thanks for info! Excellent advice and exactly what I was looking for. I’ll add mic first and rest later. What modification to reduce hiss are you talking about ?

Dan and others,
When comparing the options, first think about what you want from the radio/modification process. 

If you are a tinkerer/programmer and want to dabble in the software, the TSW solution can make sense as it is open source and you have a lot of memory and speed available to add things.

If you are more into operating, then I believe that there are more options available with the KD8CEC/Nextion including IF shift, Attenuation, Spectrum Scope, and others when a 2nd Nano is added.  You should look through all of the choices on the HamsKey.com blog.  One of the big ones for me is the Memory Manager software that does not have an equivalent on the other choices.  There is also support for an SDR link to have a panadapter on a linked computer with many SDR dongles.

The last thing most will consider is future upgrades.  I would not put too much into this category, as the v6 changed a lot of the future direction recently, and that can happen again.  With that understanding, we have not heard much from Dr. Ian Lee recently.  All of his code is open source, so anyone could pick it up and add a new feature.  The TSW activity is recent, focused on the new v6, and also open source.  All of that makes it a wash for me.

Hardware modes like AGC, Speach compression, CW audio filters can be done on any of the above mods.

If I were just starting with the uBiTx, the order would be:
1 - First get it working as supplied by HF Signals. 
2 - Fix any hardware issues like the mic problems.  Clean up the sound (small mod to the LM386 to remove hiss).  Install diode protection if it will be near higher power transmitters without a grounded antenna input.
3 - Try out the FREE software from Reed to improve operability.  You can always go back, it is software.
4 - Add an AGC mod.  I have not done this yet, and have two different versions to try.  I would suggest one that reduces gain prior to the audio sections, either at the first RF sections or the IF sections.
5 - Then go for more complex upgrades based on what you want to do with the radio.  I have 3 and have focused one on digital, working on one for CW and a general use radio with ease of use items.
6 - Add a linear amp.

Above are my opinions.  Others may be different, and that is as it should be.  You need to make your own choices and live with the results.

Re: V4 Alignment

Adrian Rees
 

As an update,

I connected test pins to Test Points 12, & 16 on my v4 uBITX board.

I also connected a dummy load, speaker, microphone etc.

Upon switching on the radio defaulted to its usual 7.150MHz LSB setting

Test point 12 measured over 53MHz.

I switched the radio in settings & calibrate, and TP 12 measured something like 10.005MHz.

By turning the tuning knob I managed to change this to 10MHz, saving the setting and restarting resulting in TP12 measuring 52.14991 MHz.

Good enough.

I then measured TP16 and adjusted the SSB setting until I measured 11.99664MHz, saved & restarted.

All seems well and the radio is now retaining its settings.

The test points are loacted just behind the raduino connector and are marked TP12 and TP16, although TP16 is hard to spot as it was overprinted on my board. its next to R112.

Note, my frequency settings are for my v4 board with 12MHz crystals, yours maybe different.

Cheers

Re: Will this mic work?

Dale Parfitt
 

Spot on Evan,

There is a hand mic version of the Astatic  D-104 that uses an internal battery. I have used them on my vintage rigs and get excellent audio reports.  All this assumes the mic gain stages (as designed) of the BitX are inadequate- I have not confirmed this myself.

Subject: Re: [BITX20] Will this mic work?

 

As far as I can tell without the schematic of the mic, it will not work.  The input of the uBitx has approximately 5 K ohms for the bias of the electret element.  If the current draw of the mic is 5 ma, then the drop across that resistor would be 25 volts.  At most the supplied voltage is 12 volts (13.8 with a "normal" ham supply).  Not enough to run the mic.  You would need to drop the resistor in the uBiTx mic circuit (R60) to 680 ohms  That would give a drop of (680+220)*.005=4.5 volts  That leaves 7.5 volts for the mic.  NOTE: there is a 220 ohm resistor ahead of R60.

The PTT line on the uBiTx is a direct input on the Nano, so the 2 ma max draw should not be an issue.  If there is an issue, a pull-up resistor (2.2 K) should fix it.

Please double-check the above before you implement it.  My recommendation is to go with another solution like a 9 volt battery in the mic or wire a separate supply at the mic connector in the uBiTx.  This will depend on if you want to use an electret without a built-in amp in addition to the amplified one.  If you are going to dedicate the mic and rig together, then swap the resistor after you do more verification.

Just suggestions.  The short answer is that it will not work.

Re: V4 Alignment

@KF4ZGZ
 

It seems the turn off re-boot thing is important after every step.
At least it is on my v6.
Mine wasn't appearing to do well either in getting the frequency close, but the bfo seemed fine.
I stopped for the night, turned it on the next day and all was fine?
Only off a bit .... close enough to leave it be.
