Has anyone tried to us the LDG Z-817 autotuner meant to be used with the FT-817 with the uBitx.?

God what a PITA it wont read a 128gb microSD. When I format a 32gb microSD with the file the compiter reads as ok, it says
"no file"!!!

Turn off rig.
Sdcard into nextion (only 1 .tft file)
turn on rig.
Should see text about it loading. Will show successful when done.
turn off rig
remove sdcard
turn on rig....? should see new screen.

OK so if I load the .tft file into the nextion that will make the screen work with the ubitx or is there another file needed to be loaded into the ubitx?

The files that end with .tft only go into the screen module itself, by means of a MicroSD card holding ONLY that one file on it at the time. If you're not happy with the 3.5" screen you find, report back and look in the forum Files section for a re-work of a 3.2" screen expanded to completely fill a 3.5" field. Best of luck, TedK3RTA

Re: New Nextion display V5 signal or stand alone analyzer CEC 1.122
Rich,
? I am not sure what your asking? Do you want a pic of my installation or just the display. If you want a pic of the display look at this site.?
Thanks

Re: Deaf and Dumb uBitxV4
Joe,
Not known but for us it's a convenient place to probe! Just a reference point me to compare two boards.
They are all where I want them, maybe a few more are required.
There are not many number of us who have the equipment to make use of any published numbers.

Received another board from vu2pop last night. S.No 007/2 from Farhan.
Nothing much heard from the receiver and with a strong signal from the generator some distorted audio.
Transmit was as bad, about 100mW.
TX RX both poor so it has to be something in the common circuit.
To cut the story short, I checked and compared the levels at all the RF RX points with a good board.
Everything was fine at all test points except TP20 which is audio.
Whn I put the probe on D5 there was some change.. pressed one contact and the volume almost
blew my ears.. guess what - a bad solder. resoldered it and all is well with #7/2!
Mostly the issues are simple but takes a lot of patience to find and fix.

Thank you to all those who helped me. It went together well. All is working.
Now how to install the firmware to get the Nextion 3.5 to work.
I have downloaded these two files:v1.092 - 3.5¡å Enhanced Nextion Screen files (HMI for loading into Nextion Editor) ¨C KN4UD
and?1.092 - 3.5¡å Enhanced Nextion Screen files (TFT for loading on micro-SD) ¨C KN4UD.
Is it installed only on the display or must it also be installed on the ubitx? How is it done?
Thanks again Laddie

Earl,
You have your caps lock on. There are some uilities which disable that key. I sometimes remove the key top!
When you put in a case it is highly likely you accidentally plugged the raduino shifted by one pin left or right
or like me shifted the display one pin left or right. Usually this kills them and need replacement.
Try changing the display. Easily available.

Please notice there is an adjustment pot associated with the lcd display. It must be carefully adjusted to see letters and numbers. Try to get this working first.
Since you can't see the display,? might be locked into a menu setting, well until you remove power. If there is an issue I would check solder connections we make for issues. Make sure you didn't make a short near the antenna connection. Assume its not on the board for now.

Allison,
If using BFR106E6327HTSA1 to replace all the 2n3904's in the transmit section, are the emitter resistor values
described in the Wiki still good?
Thank you,

Where can I get a voltage chart for Bitx 40?

NO SIGNALS? AND ONLY BLOCKS ON RADUINO VOLUME OK. THANKS EARL , VE1AWC@ GMAIL
