Thanks, Evan. I have looked at so many web sites and stuff in the past couple of days I can't remember where ANYTHING is! But, I seem to recall running across somebody upgrading to a 3.5" screen succe

DJ, You are welcome, though not sure why 875 adjusted by more than 1Hz. I will have to go back and look at the code again. 5Hz error is really good in my book. 73 Evan AC9TU

Scott, based on my vast experience (all of it learned today! :-) ) I would agree that yours is about 160 Hz high. Mine started out around 320 Hz high before I went through the tuning procedure, bringi

Thank you Evan! That explanation makes sense, and I was able to tweak the tuning successfully. Interestingly enough, on my uBitx one increment of tuning (875) results in a 22 Hz difference in FT8. Nev

SM6MOJ, Since you have the correct hex file loaded, and connecting an antenna does not increase the background noise, then you have one of the receiver's stages not functioning properly. This points t

Justin, The tft file that you found is one that does not use the full screen. Finding the correct tft file is a challenge. Try this message to see if it meets your needs: https://groups.io/g/BITX20/me

This is amazing, I was about to post a nearly identical question and decided to do some reading first. Saved opening another thread - good on me. Unlike you I don't have a second radio to test with bu

Dj, The FT8 frequency on the µBIKTX is a function of both the Master Calibration and the BFO tuning. Either can change the displayed frequency on the FT8 software. The way that I would do the calibrat

Did the deed. I was planning on nipping the BNC leads right near the board and simply bending them out of the way a touch. I was thinking I could easily undo this with a few drops of solder if I wante

Hi Jim, This sometimes happens to my uBITX V4 radio when it is connected to my laptop USB port. I can restore the radio using either of two methods. First method : Switch OFF radio, disconnect USB cab

Jim My suspicion would be a power supply problem. Some power regulators regulate upward, but a few regulate downward. Those that regulate downward cat let the voltage initially climb to excessive valu

I would reload the sketch and go from there. I had a similar issue. Barry

Yesterday afternoon I was in the shack with the uBitx and everything was working fine. I shut it down as always, and when I came back today and turned it on, it didn't work. There is nothing but zeros

Hi all, I am trying to fine tune my uBitx v6 w/ 6.1 firmware. It could be that my understanding is faulty, and I'm hoping for some clarification. I have two identical Raspberry Pi 4 computers running

That's slick, I have one on my Amazon "wish list." I was super excited to get today started as my Nextion 3.5" display and spare Nanos got here yesterday evening. I downloaded the files I thought I ne

Folks, My post from a different stream. It may help. Folks, A data sheet is usually a good start to avoid the “fake news”. This data extracted from https://www.eemb.com/. Ambient Temperature:25±5℃; Re

I did upload UBITXV5_CEC_V1.200_NX.hex There is no noticeable change in sound when I connect an antenna. Have tried several different microphones, with the same result.

You are lucky with the temp sensor. There some soldering handles WITHOUT sensor. They measure the resistance of the heating element by switching the heating element between power and resistance monito
