Dave i have a fully populated version 3 board minus raduino email me off site daveg0ayd@...

I've been having fun with my V6 uBITX on the air while I'm waiting on some revised prototype boards to arrive from China.? I'm mainly a CW op and and that usually works best QRP anyway. Worked K9CT

That EEPROM thing is inside the ATMega328P processor chip used on the Nano. http://ww1.microchip.com/downloads/en/DeviceDoc/Atmel-7810-Automotive-Microcontrollers-ATmega328P_Datasheet.pdf It's 512

Glad you found it. Ideally, all firmware would have sanity checks on critical values stored in firmware, ignore them if they are out of bounds. And there should be an easy and obvious menu entry to

I have the same question did you ever get a answer? Mike

Thanks for the reply Jerry and I think you're basically correct.? It's working again.? The problem was the calibration value that was stored in the EEPROM (where ever that thing may be).? I was

Simple question: Are you using the factory V5 firmware?? Confirmed that your board is a V5? With board changes from V3/4 to V5 the BFO and filter circuits changed. I haven't gone through the logic

My power socket does not provide a good connection. Where can I buy new ones (preferably on aliexpress). What is the socket model

I would also check that there is not an issue with one of the relays/LPFs.? Without power connected to the PA (brown power wire), check each band for continuity from the antenna jack to TP7.? You

Try sending CW, do you get any power out? If not, my best guess is that the Si5351 is not working for some reason. You can verify this by bringing a shortwave receiver near your uBitx (or bringing

F4huy, My best guess is a broken or shorted wire in one of the transformers: T8,9,10,11 The fact that you get 2 Watts of SSB at 30mhz is good news, that shows that everything from the mike to the
