I'm a software guy and am a bag of hammers when it comes to the EE stuff, but this is very interesting to me, since we have so many people who are worried about the harmonics. Thanks for the post!!

Alignment of Bitx40

craigmclean@...
 

Hello.

I just finished building my Bitx40 v3 board using a amateurradiokits.in case and a Baofeng mic modified as per 

https://drive.google.com/file/d/0B8v7bRFPZV71U3BVR28zUEdkN2M/view

The receive seems to work well.  I hooked the radio up to a receive loop antennas and was able to hear some local stations called CQ for a contest.  I then plugged the Bitx40 into a dummy load and put an ammeter in line with the power connection to do the alignment.  This is where things went a bit wrong.  

According to the Alignment of the Bix 40 section of this page

http://www.hfsignals.com/index.php/2017/11/23/wiring-up-the-bitx40/

I should adjust RV1 fully clockwise so the ammeter reads 0, however when I turn the radio on the ammeter immediately reads 150mA, no matter how I adjust RV1.  If I key down current jumps from 150mA to some other value depending on how RV1 is adjusted (between 280mA and 1A).  I also noticed that when I do the HAALOOOWW into the Mic current doesn't change at all even though I've keyed down (setting RV1 doesn't seem to change this at all).  I've also fiddled with RV136 which made no difference.

My PTT seems to be working, however I'm suspicious of the Mic.  I did check continuity from the pads of the electret all the way to the board and it is good.  The PTT and electret do share a common ground as per the instructions I linked above.

So basically two problems.
Receive current should be close to zero according to alignment instructions, but it's 150mA.  Also I push the PTT and current jumps a bit, but doesn't jump when I speak into the Mic.

Any thoughts?
Craig (VE6TBW).

Re: PTT for uBITX ?

M Garza <mgarza896@...>
 

To cause PTT, you need to go low.
PTT actually is happening via the Raduino and not directly from the transistor drivers.
Please look at the first image on this page:  http://www.hfsignals.com/index.php/ubitx-wire-up/.
PTT is wired directly to the Raduino.

Hope this helps.

Re: uBitx Software Update

Hi Bill and others more ...
 
it was how I think about myself : Most I`m thinking to complicate !
I found this video from KD8CEC :  https://www.youtube.com/watch?v=fxquxqv7fAA
 
My next step was looking for “XLoader” , downloaded and installed .
Then downloaded only the KD8CEC FW v1.08 hex-zip , saved and unzipped .
The same with the uBITX-Manager .
With XLoader uploaded the FW v1.08 into the Arduino-Nano , successfull !
After this running the uBITX-Manager configured and write to Arduino the new
done settings !
All works successfull : CW-Sidetone changed &stored and encoder-tune-steps now 10 Hz .
 
Thank you all for bearing the discussion about my stupid questions ...

Toroidal transformer values, toroids, windings, #ubitx #ubitx-help #parts

cburf1@...
 

Hi all,

I'm about to embark on my first homebrew transceiver and have chosen the uBITX. I am lucky to have been given access to a large collection of unwanted though-hole components as we have gradually moved to surface mount at my company. For this reason, I am looking to do a project similar to this:  http://ubitx.net/2018/07/02/homebrew-ubitx-with-through-hole-components/

My questions for now all regard the toroidal transformers. I can't find any info about these.

1. What toroids are used?
2. How many wraps of wire?
3. Are there any off-the-shelf alternatives anyone knows of should I choose to buy them?

Thanks for the help.

I also already checked this internet links , but it always there are so many things

also not a step by step instruction for doing the uBITX  FW upgrade ..
 
The only way for me is to get a step by step instruction that I can follow
and understand each step ... but all what I find is written for insider who have
basic experiences and knowledge about Arduino-Nano ...
but I am a complete newcomer ... sorry ...
 
The only thing I have just installed is the “Arduino IDE” – software

I removed the noise. It had nothing to do with biasing. I proved this with my Siglent Scope. I observed no distortion on zero crossing.

Hi Daniel,

When we measure devices 'in situ' (connected to the rest of the radio) other parts can influence the measurements. I have not looked to see if those pots have other bits to alter your resistance measurements but just to make you (and others) aware. Apparently 2.1 k might be adequate:)

Re: Received modulation is good only if IFS is 1400-1810

Dr. Flywheel
 

Individual component behavior can vary circuit response curve. This is a known fact and a proper design typically includes measures to compensate for statistical deviation from the norm. In the case of the V4 audio, I am getting very good audio output, once I took care of VFO and BFO calibration and then set the IF SHIFT to 2500 Hz. My audio circuits are not modified from the original design for the V4 audio (which does not use the TDA IC). In the long run I intend to change the software (very slightly) by an IF_CALIBRATION value (in my case 2500) to the code statement that set the oscillator. This would set my oscillator frequency to fall in the middle of the crystal filter pass-band, rather than on the sideline. When the oscillator frequency falls on the crystal filter side line, part of the audio spectrum is cut off very sharply (in my case the low frequencies on LSB) and in addition, the received signals are also severely attenuated.

Note that the symptoms that I a describing are not the same as the problem that Raj is suggesting to fix. The audio amplifier clipping problem can still exist for some of you and I suggest to fix them per Raj's suggestions, after you verified your VFO, BFO and IF SHIFT setting is close to optimal.

The current oscillator (CEC version) code looks as shown below. This code does not figure out compensation for crystal filters that have a shifted pass-band. I am suggesting to add a correction factor in the code that will allow the user to set an IF_FILTER_DEVIATION value (stored in the EEPROM) that will correct for IF Filter pass-band center, deviation from the norm.

void SetCarrierFreq()
{
  unsigned long appliedCarrier = ((cwMode == 0 ? usbCarrier : cwmCarrier) + (isIFShift && (inTx == 0) ? ifShiftValue : 0));
  //si5351bx_setfreq(0, (sdrModeOn ? 0 : appliedCarrier));
  si5351bx_setfreq(0, ((sdrModeOn && (inTx == 0)) ? 0 : appliedCarrier)); //found bug by KG4GEK
  
    /*
  if (cwMode == 0)
    si5351bx_setfreq(0, usbCarrier + (isIFShift ? ifShiftValue : 0));
  else
    si5351bx_setfreq(0, cwmCarrier + (isIFShift ? ifShiftValue : 0));
    */
}

Please do the audio quiescent current mod that I have suggested in this group.
The low volume distortion makes the background hiss to sound like crackling.

P.S the relevant bits are left trailing.. (someone asked about what it relevant bits)

At 08-10-18, you wrote:

On mine uBitx there is a constant noise, somewhat crackling like a meat frying on a pan, that on the spectrum looks like a bump with peak around 2.5 or maybe 3 kHz. I can shift it with IF shift, but never loose it. I tried decoding FT8 and it goes quite well even if under this bump. SSB is hard to understand though, and only putting IF at 1600 makes it somewhat clearer. I can read very strong signals, but weaker are no-go.

Oh and my current stored IF shift is 0, if I read the dump correctly.

Hi jens,

I am using the original display, too. Those touchscreen things are cool but I see my uBitX as a utilitarian radio. The CEC software will somewhat rearrange the info displayed but nothing radical. It will still show you your frequency, the frequency of the other VFO, your mode, and your tuning step. Have fun with your radio.

Thanks Bill ,

so if the 10 Hz tuning steps will be available with KD8CEC firmware
then I will see to do the update . To can go down from 100 Hz to
50 Hz and 10 Hz is my major intention for an update ,
other are not so important , because I have the original LCD-display 16x2.

Hi Jens,

I installed the CEC software in my uBitX and it took care of all the
issues I expected it to. First is that tuning step. It will go to 10 Hz
steps and up to 1kc steps for larger changes in frequency. there are
steps at 50, 100, and 500 cycles per second too. It is easy to get use
that feature. The other, equally important feature is the CW actually
*works*. The original CW operation is erratic. I haven't tried changing
the sidetone so I can't compare the original software and CEC for that.

I hope this helps.

Hi Jack ,

at first thanks for Your answer .
But before I want start an update ... I have to questions about the
result
:
Now my uBITX (v3) has the original firmware .

There are two things which make me not happy :

1) The CW sidetone frequency I can choose in the menue and also adjust
but the
new setting will absolutly not saved by press for confirm the PTT... -
like described.

2) The transceiver frequency tuning (enccoder-) steps are to much large
with 100 Hz .
I saw , that with the firmware 1.08 from KD8CEC I could it can change
down to 10 Hz .
Is that right or not ... ???

Jens:

I do not use Dr. Lee's code, mainly because I am writing my own replacement for it. However, as I understand it, he has a program that runs on the PC that saves certain data to EEPROM, which can then be used at runtime. Have you run that software to see if there is an input that lets you set the sidetone frequency? I'll bet the same is true for the frequency increment.

I just googled "How to install the Arduino IDE" and got 5.6 million hits! I'm sure one of those will be just perfect to get you started. It's really very simple to do and it will open a new world to you and may become a new source of enjoyment for our hobby. If you ever get to the point where you want to start playing around with programming these devices in C, I can suggest a book for you!  :>)

Hi Jens,

not a problem at all: please look here: http://ubitx.net/
Also you find many youtube videos concerning the KD8CEC firmware.
Ian also describes how to install on his blog http://www.hamskey.com/2018/09/ubitx-firmware-cec-version-11-release.html#more
There he provides precompiled hexfiles for easy upload. You don't need the bitx Manager tool at this point.
See http://www.hamskey.com/2018/01/how-to-upgrade-ubitx-firmware.html for installing the firmware.
