Ian has stated that he is working on a V5 version of his software. It looks like new functions could be included too (power meter?, SWR meter?). See https://groups.io/g/BITX20/message/65520

Thanks, John.

Re: No TX #ubitx

Well, I removed the parallel so it's back to stock resistance. Three separate 2n2222's measure 2.8v on the emitter, 3.8 on the base, and 11.8 on the collector. The (now same as stock) 100ohm resistor at the emitter apparently goes to earth as it should, and no errant solder blobs seen in the area.  I'm starting to think iI'm just not supposed to have a working radio.

Voltages at test points on V4 boards #bitx40help #calibration

Jon Sumpter
 

Is there a publication that has the expected voltages at the various test points (TPx) on the version 4 uBITX board?

Bill,

There is very little setup.  I only needed to tweak the BFO frequency.  The fact that the VFO isn’t tracking properly isn’t something you can “set up”.  If your tuning is erratic I would suggest rechecking  your encoder wiring as a first step.

So...Again, what meter are you measuring with ...Do you have any way to "bread-board" that circuit (just the "r's" and transistor) to see what you get? ..It is VERY unusual for any transistor to have greater than .7 volts difference between emitter and base (when properly biased)

Re: No TX #ubitx

OK, here' s a basic gotcha ... How are you making these measurements? Trying to measure DC voltages with RF on them ( you did mention CW, key-down)? Now, to go from strart: Firstly, I take it this all refers to a uBitx? Then R80 (not R81?). Given that, R80 applies ONLY to ONE transistor, Q90. Liftin C80 to remove the RF might give you sane DC readings  - here onwards. Once you can verify they're all OK (3 stages, Q90, Q911-912, Q92,93,96,97) then restore C80 and use an RF probe! Your multimeter's  AC range does NOT work at these frequencies! A diode and small capacitor from the 'junkbox' (you do have one, don't you?) will serve, as many previous posts will attest. By now you might be able to give sane measurements, both DC and RF, and from them determined (with further assistance here if necessary) just where your problem lies.

Re: Latest firmwares for 7" Nextion Resistive Displays

Alex

you can download Nextion 7" GUI File from ubitx.net

the uBITX firmware CEC Version 1.11 does not work properly in V5.
You are currently deploying a beta version (Version 1.12)
Click the link below to download.

I am doing some experiments now. I will release it after the experiment ends.

Greetings, I am seeking to ensure I have the latest available firmware (.TFT file) for my Nextion 7" Resistive touch display. I have found many different sizes and variants of files aptly named for the 7" display, only to find that some only fill the screen 1/3 of the way or they are apparently for another version or display hardware. I am trying to be aware of filenames to ensure flashing the correct file. I did manage to get one working, but I dont know if its legacy or current. I have a brand new v5 uBitx that I intend to use it with Dr. Ian's 1.1 firmware.

I have this exact display: Nextion 7" Resistive Touch Input Model #NX8048K070-011R.

Thank you kindly!

Released a beta version of the firmware CEC Version 1.12 for uBITX V5 #ubitx

Ian Lee
 

Released a beta version of the firmware CEC Version 1.12 for uBITX V5

All existing firmware functions for V3 and V4 are available on V5. uBITX Manager can use the same version.
https://github.com/phdlee/ubitx/releases/download/v1.11/uBITX_Manager_V1.11.zip

Only the LPF control and the frequency control part are changed as the V5 code.

I am doing some experiments now. I will release it after the experiment ends.

Re: Latest firmwares for 7" Nextion Resistive Displays

Ian,

Thank you for the quick reply. I believe I found the issue... Looks like the firmware TFT files you posted the link to are for the basic displays. When I opened the HMI file in the nextion editor it shows it was configured for device ID indicating basic. I am going to change it to enhanced and recompile it and see if that works. Thank you for all of your hard work. I am very excited to put my new v5 board and your CEC firmware to the test.

As you already know, Basic and Enhanced versions simply change the ID.

then compile it

click the file -> Open build folder, you find compiled .tft file
Copy the file to the SD card and insert it into the LCD.

The firmware for V5 is almost done. I am going to experiment and release some more. If you have V5, you can download the beta now.

I am still looking for someone to help me with the experiment because I do not have V5 yet.

Hi, Dr Lee.

My V5 should arrive any day now, and I'll be happy to fiddle around with the basic program. I may not do much in modifications of the hardware at first but it'll get a workout at least.

Thank you for your work & your contributions to the hobby.

Re: ubitx

The stock firmware behaves relative to how fast you turn the knob. Try tuning very slow to see how it behaves. As I tuned I would get a bit excited and speed up to tune in a signal, no this does not work. Stay steady exceot when you are trying to move to the other end of a band. If this doesn't solve it, then check encoder connections as suggested.

Re: No TX #ubitx

Ted
 



Yes, I have a "junkbox". Some would say it's that 2 X 3 X 3 metre radio room I use for expressing cuss words from the blemish above my shoulders.

Anyway - After working on this again today, I verified readings with a dead mike key, not CW, and find Q90 voltages right about where the popular V3 voltage chart says things should be. That is, I'm getting 2.94v on the emitter, 3.7v on the base,and 11.6 the collector.  Please note that the surface mount 2n3094 was replaced with a can-type 2n2222a.

I'll grab some parts and make the diode/capacitor probe mentioned, tomorrow, and report back.

73,
Ted

Re: No TX #ubitx

 

3.8V Base should have 3.2 on Emitter or something is wrong if there is 1Vbe.
