Spencer, Are you using different Nanos for the two Raduinos?? If so, you need to calibrate the uBitx with the new Nano.? The calibration settings are stored in the EEPROM of the Nano that are not

Hi Spencer, I installed a 7809 regulator with a cooling fin on the Raduino board to reduce the dissipation of the 7805. 73, de Andrea

Cal, Pull the Raduino-display unit from the main board. Check that J1 on the display board has a solder blob. Power the Raduino-display unit through USB and see if works stand alone. plug in the

Hi Mark, The majority of the current consumption in transmit is the RF stages and relays which are powered from the 12V input. The LM7805 regulator 5V output powers the Raduino and the display. The

Assembly went together OK except the display didn't function. Managed, eventually, to get the tuning cable connected to the right place. That took care of several non-functioning things. ? Got

Hi Steve, I also have a V1 DE and I have a question for you. Would you mind posting a copy of your image or explaining in detail how you made the image? Thank you in advance, Robert, AG6LK

Hello all, What type of plug does the Sbitx DE use for the microphone jack, is it a 3/8 stereo plug? How is it wired up? A diagram would be great. I I know this is a dumb question and I should be

Spencer, the Nextion data sheet says the 5” draws 200ma @5v @ 100% brightness. The uBITX (probably depending on the version) adds another 160ma. So on receive the 7805 should be able to deal with

Mark, The 7805 does certainly get hot after a short while.? I've never left it on for too long due to that.? I have a couple buck converters that I picked up a while back.? I'll try installing one

I got a new Nano, flashed the uBitX V6 firmware on it, plugged it in, and I saw the same issue. I tinkered around and tried a second board, some different firmware, but with no result. I will see if

I see what you mean, have to think on that. Joel N6ALT

Hi Dan; I just did this with my DE this afternoon - the new web based GUI is happily running on my DE right now, receiving lots of FT-8 signals on 20 meters. Recommend trying the radio for at least

Neither book is available yet. The print version should be available next week. At this moment, we are not planning an eBook version. Jack, W8TEE

Spencer, A 5 inch absolutely needs its own power supply. Using the onboard 7805 will result in thermal shutdown. (been there... it appears to work for a while... then screen blanks, reboots, or other

witcg one dou have?? the $209 .00 dose no have one u ave to add it tyur self im told by a buddy that has 1

loopMasta - it seems like something is wrong around the first mixer U5. Can you check again the LO input at C31, and see if it starts around 43 MHz when you're on the 80 meter band, and goes up in

Any one experienced this? It does not always happen at the same place.

I know this is a stupid question but how to I install the V2 software in the V1 DE. I have SN: 0053 which I just took out of the box. I intend to purchase a V2 board in the near future. Dan KD3CEU

I couldn't get it to work. I get a little bit of noise if I connect C68 with a capacitor to the antenna jack but no FT8 on 14.074
