Do you use Farhan's ubitx v3 board or made one for yourself? Regards MVS Sarma

once one could design his own board , perhaps integrating the si chip also on board simplifies things. While saying so, I assume, that si chips lives long enough. rtegards sarma

Hi!!!? My ubitx rx audio level on 80m and 40m bands is good, but 20m and above is very low. I verified my antena with other radios and is working fine. Even the tx on 20m up to 10m is up to spec,

Hi Dennis, Yes, see here:?https://vk4pln.blogspot.com/2018/03/vk4pln-ubitx-add-on-boards.html Cheers.

Looks like there is a way to use the TJC with the NXT firmwares... : https://translate.google.com.au/translate?hl=en&sl=ru&u=http://robotclass.ru/tutorials/arduino-nextion-tjc/&prev=search 73.

Mike Hagen, WA6ISP, is selling an "improved" Raduino for roughly $48. It is completely assembled for that price. If you Google his name and call sign you should get an email address for him or just

Hi All,? SO what happens if you have a TJC screen? Hoping they are not useless now... 73 NIck

You could ask Mike Hagen, WA6ISP, if he would share his design/... for his modified Raduino. Its structure is probably the easiest part of your planned endeavor.

Hello Woolf, I have Eagle layout files for the RF sections of the UbitX. I took a modular approach, so there are several circuit boards that you could make a UbitX or a single conversion design. I've

Could be a blown IO cell on either the Nano or the display. That would happen if you shorted one of your separation cable wires to something like 12v or the like. More likely, one of the 6 wires from

John It seems that everything is working except the LCD display...? If that is the case then I would look for a bad solder connection in the 4 data leads that connect the LCD to the Raduino board. A

I just heard AB0WR on trying to work a W9 call. I tried giving you a cal. But you cleared out, you were strong here in western NC. Skip NC9O

Soldering the si5351 would be the main challenge. Your best bet would be to buy the qrp labs' si5351 synth kit and solder it as a daughter board onto the main rf board. A small perf board can take the

Yes think so too, just hooked the antenna and a speaker up and I hear FT8 coming in on 20m so the uBitX itself is working. Unfortunate I already had a blue backlight ordered but didn't pay

Just guessing here, but maybe static fried the display.? You can get a new display on eBay, AliExpress, Amazon or Adafruit.? Dan, W2DLC

I have also seen people put ?a few ferrite beads on the power leads to the fan to kill noise creeping back into the supply.? Michael VE3WMB

Sorry to hear your miss fortune with the BITX transceivers but if it could help you feel better I’m sure there is someone local that would be willing to help you get those units repaired. You could

I didn't use my uBitX for a while and today when I hooked it up my display was garbled. I was afraid that my seperation cable might be the problem, but even with the display directly connected to the

I would venture a guess that his parcels arrived as they did as he probably rubbed his pleasant attitude on his mail delivery person and has since garnered himself a target for the blatant relief of

John, once again, your software saved me tons of time in troubleshooting. It turns out I have a bad 5351 on the Raduino now.. looking for possibilities of replacing it either as a chip or completely
