Hi Charley, thanks for posting this. I just wrote an article on the STM32F429 Development board as used by Alberto I2PHD for an ARM Radio for LW/MW. It is in the FUNKAMATEUR December 2019 issue. I had

Have you tried adjusting the BFO frequency? Often that is the problem with poor or distorted audio. =Vic=

Hi Arv, I've just got my Ubitx to to talk to GRIG, here is command that worked for me grig --model=120 --rig-file=/dev/ttyUSB0 --speed=38400 also this page appears at the top of my Google search when

The 2.8 size is likely not the problem. You need to have the display driver (e.g., ILI9341) on the display match the library used to process the code. Check to see if the display you ordered matches t

Me and David over at kit-projects try our best to stand by our stuff, we do the best we can to make sure its built right so it works out of the box. We would feel terrible selling it here otherwise. S

Another example of why I like this forum. Tim is willing to accept this is a defect, and Joel is working hard to prove It is not! I enjoyed following your combined troubleshooting techniques. Thanks.

No worries and no need to send it back :) not the easiest modules to test with out putting it in a radio sadly! Again thanks for trying to help us figure it out! Tim Keller -- Tim Keller - KE2GKB http

Tim, I'm afraid I cant perform anymore tests as I removed the board from my radio, but I had made a similar test only without removing the V lead and it made no difference. By the way, my radio is now

Update: I had a 3.2 display here so I just loaded that one and it worked right off. I'll just get a 3.2 front piece and forget the 2.8. It's already on the way back to Amazon. Looks like I got someone

I'm afraid I'm at a loss joel, I want to ask you to short the RFIN and Out with a jumper, Remove the Volume wire and put the switch in the off position just to make sure that its the agc (effectively/

Correct voltages are present, 5V is 5.23V Joel

Morris, I had the same problem with my 2.8 Nextion. Try "UBITX_Nextion_GUI_V3\ubitx_28.TFT". Make sure it is a TFT file and not an HMI file. There are others that will work but try this one first. Hav

So at this point we have a replacement unit pulled to the side for you out of the latest production batch if that is what it comes to again thank you for taking the time to poke at it to try to find o

Trying to load nextion firmware on a 2.8 lcd. The load is saying that the model in the firmware and the model of the lcd don't match. Is that a known problem? I have double checked that I have the rig

Tim, On a strong signal with the antenna connected the S meter pad just tickles my auto ranging meter, basically nothing there. Without a antenna there is nothing, 0. Joel N6ALT

Everything seems to be in order, How interesting. Can you get the voltage off the S-Meter pad for me? with a signal present and with the antenna disconnected? Last thing to check before i'm going to s

Hi Tim, I shorted the common pad to the off pad and then I tried all the pads individually shorted to the common pad, very slight difference between them. Joel

Did you short the Common to Ground on the switch pads? Just leaving it open is actually setting it to a SUPER SLOW agc motion and will give you even weirder results. Can you show me where the yellow V

Tim, It doesn't make any difference where the switch selection is, the audio sounds the same. Attached is the best picture I can take. Joel

Just jumping RF In/Out wont remove the agc from the circuit, It has a shunt element that would still be active :) IN order to remove the shunt element as well you would need to put the switch pads int
