You can check voltages on all transistors in any case... you will find data somwhere in list archive.
Good luck

Bitx 40 no receive
From: Michael Herron
Date: Thu, 23 May 2019 22:49:07 PDT
I have a Bitx 40 I am troubleshooting that a friend put together. The display comes on okay and covers the entire 40 meter band when I tune it. I do not get any indication of it receiving nor any volume out of it with the volume control and an 8 Ohm speaker soldered to the speaker leads.
I have watched the troubleshooting video. I do not get any noise touching a probe to the center conductor of the SO-239 and no antenna attached. I also do not get any noise when touching the probe to C107.
The video does not talk about what to look for if that occurs.
I was hoping that someone would have some ideas where to start out with this problem. I have checked the volume control a couple times and it is wired correctly. I have not yet checked the current draw of the radio
as I will have to dig up a power cable I have for doing just that.
Any assistance or tips on figuring this out is much appreciated.
Mike K7MH.

What have you found out. Perhaps a loose wire on the audio jack where it leaves the main board. Wiggle it. I doubt if it is serious.
I had a low whine on one used radio and vfo was off about 2kc. I could hear the stations but the whine was persistent. Perhaps you mods are pulling the voltage too low or worse injecting some power into the ubitx.

Re: Ubitx V3 Rx problems
From: Impulsive.force@...
Date: Fri, 24 May 2019 07:11:25 PDT
I have removed all modifications (which were only to speaker and mic via capacitors) - no change
I have replaced the audio amp - no change
I have reloaded the original software - no change
My scope is not very good (only 20MHz) but checking the clocks CLK#0 is at 12MHz about 1v p-p on main boad
Using my frequency counter I get CLK#1 switching between 33MHz and 57MHz (USB/LSB)
and CLK#0 at 59.1 MHz when tuned to 14.1MHz which is the correct 45MHz tuning and the frequency changes with tuning
So although I cant check the waveshape and amplitude (dont know what amplitude is should be but si5351 datasheet indicates 0.6 VOL to 3.3-0.6 VOH)
Something has definately changed on the board and I can hear soft 'clicks' as I tune the frequency, the audio signal is very quiet but I can tune signals. There are now whistles at some specific frequencies where as I tune the tone chages with each 100Hz tuning step. e.g.
14,180.7 audio tone perhaps 5Khz
14,180.6 audio tone perhaps 2KHz
14,180.5 audio tone perhaps 1Khz
14,180.4 audio tone perhaps 500hz
Any help with what to test would be a great
Thanks to all - Bob
So something is wrong

Re: Ubitx V3 Rx problems
From: Curt
Date: Fri, 24 May 2019 09:39:15 PDT
I am thinking it is something simple.? check raduino connection to main board - is it firm or flopping around?? Possibly you could have lost some I/O signal.? Same for seating the wire bundle connectors.?
Give unit a good shake in case you have a strand of wire someplace.?
See if you really have a path from antenna to the board.? If this has opened up or shorted out, you would hear some of the clocks and things that used to be below the noise.? I would check DC continuity for the whole path until we reach a blocking capacitor.? or on receive only, bypass stuff to take a clipped wire from antenna to close to the 45 MHz input.?
Although its annoying, its part of the journey.? Put your DVM and scope to use -- most of us have only simple test equipment also - and can debug just fine.?

On both my unit,(v3 unmodded and v4 modded with Mention screen) I find that the antenna changeover relays (tx to rx)give problems making on receive signals fade out or are very quiet.A few presses on the pot will restore normal receive for a while.May be worth
a look.? Regards. Ian M0IDR

Re: separate CAT jack, without using the USB cable

From: Sascha Bohnet | DL5SMB
Date: Fri, 24 May 2019 12:15:28 PDT
Hi Jonas,
great news that someone else is also doing this project with the uBITX.
I am a bit short on time (vacation starts on Sunday, still need to prepare and pack the usual staff and my radio equipment), but I'll try to summarize
as detailed as necessary.
1.)
When building the magnetic loop controller, R8 and R23 should not be 1k Resistors, use lower values. I have used 200 or 300 Ohm I think, but 100 should be fine too,
I have also used a voltage level converter to convert the serial levels from 3,3V (Teensy) to 5V (Raduino) , but maybe you don't need it. Just test it.
In my case putting it in was just a byproduct, before I realized I had to change R8 and R23.
2.)
Hook everything up then, RX from the Teensy should go to TX of the Raduino, TX of the Teensy to RX of the Raduino.
3.)
Within the ubitx firmware lower the serial speed. In my case I used 4800 baud 8N2.
4.)
If you have done everything correctly, the frequency of the uBITX will appear on th display of the loop controller
(here you must of course create a profile Yaesu 8X7 and configure the same Serial speed).
5.) Manual tuning should work by now. If you key a CW Signal (hold it) and press the Tune Button, the controller should
find the right setting (if you did the initial calibration like described in the manual of the controller)
6.) To make auto-tune over cat working, you need to make some adjustemts to the code of the uBitx firmware.
You need to define a fake AM-mode which? sends a keyed down CW signal if TX gets triggered.
Make these changements to the code within the corresponding files
File: ubitx_20

??????? //delay_background(5, 3); //removed by KD8CEC
??????? //continue;?????????????? //removed by KD8CEC
??????? return;?????????????????? //Tx stop control by Main Loop
????? }
????? Check_Cat(2);
So, I think these were all the changes needed to be done.
Good luck - and if something does not work as planned, go ahead and ask. I won't take the loop controller on vacation,
but maybe I'll remember.. And yes, that restriction to the controller means that the uBitx will be with me? :-)

Re: text labelson faceplate of rig
Nice rig OM. I agree the jacks need labels, as I have stuck headphones in a key jack before. Find a larger knob for main tuning, and then no label needed for the controls.
My club site has lots of good info, search for k3pzn ubitx

Re: text labelson faceplate of rig
I have been using an Avery product. It is a transparent plastic with an adhesive backing and you can print using either an inkjet or a laser printer. You then just cut the strips where you designed the label, peel the backing, and place on the panel. Really easy, and the results are pretty good. One sheet can produce a ton of labels, too. The product is Avery 4397.  =Vic=

Re: text labelson faceplate of rig
Brother P-touch labeler is a handy tool to have around the shack. If you've got a way to create SVGs (Adobe Illustrator, Inkscape, etc) I could cut a faceplate for you on LaserMark like I did for mine for about $10.  ?

I am trying to set up the stand alone signal meter I am running 1.2 firmware when pressing the CW panel to access the menus to go to the DSP1 panel it is not there
I thought Version 1.2 is the latest version with all the options or is it the firmware version in the nextion that is a much earlier version I found it hard to find a prebuilt version for my 3.5 nextion
Attached is a screenshot of the menu assessed via the CW info panel there seem to be other functions that are missing to

text labelson faceplate of rig
I just built a mBitx and put it in an enclosure. None of my controls, or jacks are labeled. where can I find labels for power/tune/mic/phones/key? I have tried making them on my printer, but the results were atrocious

Michael, I had same problem when BITX arrived. I suggest you first check the coils in RF filter (3 toroids close to each other). I had one torroid cut out and had no RX, but when soldered back it was all ok. For TX you can also check U2 voltages before TX. I had none but when applied solder iron to contacts again, it worked out fine.
You can check voltages on all transistors in any case... you will find data somwhere in list archive.

So, I think these were all the changes needed to be done.
Good luck - and if something does not work as planned, go ahead and ask. I won't take the loop controller on vacation,
but maybe I'll remember.. And yes, that restriction to the controller means that the uBitx will be with me? :-)

Re: uBitx v4 receive problems
Straight indication of dry contacts of the relays. In telecom we usedto feed a 2mA wetting current theo contacts of relays.?
However tou may very carefyll replace the two relays that areresponsible for rx signal pssing to the L1 to L4 filter, from ANT.

I have a V4 board running a nextion screen and KD8CEC firmware v 1.097.
After a few minutes of normal receive,the signals will fade out in a few seconds to virtually nothing.
Pressing PTT will occasionally restore normal receive as will switching it off and back on again.
This behaviour is repeatable.
Thinking it might be the antenna change over relay, I have sent for some more but interestingly I temporarily installed a previously unused v3 board with the arduino from my v4 and this exhibited the exact same behaviour leading me to think there is a issue with either the firmware or Arduino.
May I have your thoughts please.
Thankyou Ian M0IDR

Ardunio sketch to scan freqs for RF seismograph
Hi All,
I was wondering if there is a sketch to have uBitx scan bands for a few seconds each with a specidic frequency range in each band and then repeat across the bands. With this setup the RF Seismograph could be send audio without the filters and stuff.
Just wonderin'
