Well I finally gotten the STM32F769-FT8-Transceiver project to a state worth releasing.

I have placed the files required for making the project on Github at this location: https://github.com/chillmf/STM32F769-FT8-Transceiver

I hope you enjoy the project.

Regards,

Charley

I am trying to build this v5 for a blind ham in KS. I have too much going on right now. Is there anyone that could align/troubleshoot  this so that I can get it to the guy? I will pay for parts/shipping, etc.

And don’t forget the microscope we all have in our smart phones.  Take a photo and blow it up on your computer...... shows all my sins usually.  An ohm meter and a smart phone are the start of anyones build or repair kit.  In fact I bought a USB electronic microscope a few years ago at Dayton but have never had to use it... my smart phone does all I have needed so far.

Better to use an ohmmeter (DVM or other type) to see if there is continuity from 'ground connections on the board - any, they are all connected within the board) to the OUTER conductor of the coax connector.  if this is an open circuit, you aren't properly connected.  (you might be connected to the board but maybe not the case - see note about scraping paint if you case has paint). 

building RF stuff requires some investigation - use a meter always, don't trust your eyes.  don't ask about my own misadvertures!

Re: uBitX as a Shortwave Receiver?

Hello !
You can even listen long waves or lower (SAQ on 17.2Khz fo example) with the little SA612 Based VLF converter (see attached), works great

In my opinion using it just as a receiver is a bit of waste. It's an excellent choice as a qrp transceiver, but a Tecsun portable receiver like a PL660 is just more convenient with synch detector, AM, excellent SSB, excellent AGC, and you have the AM Airband as well. And plenty of volume too.

Hi Gavin.
I don't see a RF ground. The (-)DC voltage is not a ground.  On most power supplies it is a common.  If connected to ground at the supply, it is connected to mains electrical system ground, not a good RF ground.
Since you are in a metal chassis, remove the paint to have a good connection between the chassis and all the connectors including the 4 PCB stand-offs. Then bond the chassis to your RF ground.
Also make sure you have a proper size fuse inline between your power source and your uBITX.

The green/yellow/orange bundle to your volume control: Move that forward and down close to the chassis to minimize coupling from the encoder and USB

Rgds,
Gary

uBitx V4, nextion display and other mods #ubitx

dwhacks
 

Hello Group, long time lingerer, first time poster.
I've had the uBitx V4 for almost a year now, and have used it for listening a bit, but not much. Recently I met a local ham (VE7PS) that really got me interested in radio again. I have been studying for my license on and off for the last 4 or so years, and now after meeting VE7PS I am making the push. I will be taking the test early January 2020.

ANYWAY, the reason I'm writing, is I'm a tinkerer. and I've done most of the mods to my uBitx; nextion display, ND6T Stockton Bridge SWR with the extra arduino for S-Meter and SWR. Ive also got the small AGC board from kit-projects.com.

My question is; after installing the AGC and the S-Meter, where should I connect the S-meter? it says "Vol-high" but the AGC board has an S-meter pad. The AGC instructions state, that for a V4 board to connect the AGC V to R70 through a resistor instead of through VOL-HIGH. So it seems I have 3 places to choose for the S-Meter: Vol-HIGH, R70 through a resistor, and S on the AGC board.

Does anyone have any ideas?

-Dayne.

Re: Nextion Question

Evan Hand
 

Please be sure to use the correct hex file, there are a number of them.

Here is the FileNameInfo.txt listed.  Note that the hex file to use is dependent on the display that you will connect.  The the last part of the name indicates the display.  the file ending in _16P is the CEC software that will work with the original display.  The file for the Nextion displays end in _NX.  The _NX_S is for use with the I2C connected separate S meter.  Go to the Hamskey site to find out more.
