Ulf, You need to load the KD8CEC v1.20 software into the original Nano of the Raaduinno for the PC-based Memory Manager to be able to read the EEPROM for the calibration data.? Loading the KD8CEC

Hi, I can’t connect to original Arduino using KD8CEC MM, alwayd getting ”Error Receive Length”, wichever speed I am using…

Gary, Thank you.? I will read up on the process. 73 Evan AC9TU

I did a write up on changing the bootloader for more available EEPROM space on a Nano. /g/BITX20/message/85002 using the Arduino as an ISP. The ArdunioISP code is directly from the

Gary, Thank you for the method.? Do you have a link or other data on how to set up the ISP Nano, and the connection to the target Nano? Thank you. 73 Evan AC9TU

Did you try aligning the ubitx? It is possible that the settings are way off.

Ashok, Check is all three Raduino clock signals are working. I suspect not. You will need some instrument that can count or scope 100 MHz. Good Luck, Raj vu2zap

Hi all, I think finally I have found that my uBitx is unable to receive in 7 MHZ band. And other bands also poor reception. After few days checking for 40m band reception, i was unable to receive

Gary, What you say is interesting In fact I would like to know if it is possible to reinitialise a Nano completely (Return it to the factory state) He has to "fill up" with tests of versions? So, is

Rich, I would recommend rpi 4. Memory isnt an issue as very little is used otherwise. My own development machine as well as the production runs are all raspberry pi 4 with 2gb ram. At present, it is

There are other ways. Use a programmer to dump the EEPROM from the original Arduino and write that image to a new Arduino. I have a Nano set up as an "Arduino as ISP" programmer.

Ulm, You can load the KD8CEC firmware, use KD8CMC Memory Manager to read the calibration values and save them to a file. Then reload the original firmware. that is the only way to savdd we the

Hi, I just replaced the (new one) Arduino with the original Arduino and screen, and then I got better reception. Is there any way to export calibration data from original Arduino and the enter it in

Thanks all! I just pulled out the old board and couldn’t remember how this worked. It’s been a few years. -John

Hi John, As Gary stated the stock software does not have a tuning step size adjustment.? The KD8CEC firmware does, and it is free.? The CEC firmware works with the Nextion screen as well as the

I managed to get what seems to be the last?Elekitsorparts uBitx Digi-Interface in stock at Tindie.com. Of course, it came with zero instructions and a link to a YouTube video that shows installation

Hi John, It's not menu driven in factory firmware. No switch / Arduino pin value to sample to change step size. Step size changes based on the the number of encoder pulses captured during the sample

Is there a menu choice or switch to change tuning rate? I must have missed it. Pushing the vfo encoder gets a menu but I don’t see a place to set that. -John N4HNO
