Hi Dušan, It's on my to-do list. On the one hand, my knowledge in this area is limited and, on the other hand, I have doubts about whether to implement it on this board or on an additional board that

Thanks for the information, Gary and Evan! Guys like you two, Raj, and other make this group a great resource for all of us. Thanks for the measurements from your radio, Evan. If nice to know that my

Hello Stan, To answer your first question, as received from the factory my v6 uBitx is drawing 730ma for the test when I press the mic PTT button and do not supply any sound to it. I have not changed

Stan, Instructions were written prior to the added current draw of the TFT display. Yes, set the bias for 100mA increase like Raj and and instructions said.

I’m using the instructions at https://www.hfsignals.com/index.php/ubitx-tuneup/ which is essentially what you have in your post, Raj, except for one detail. These instructions say with RV2 and RV3

Good evening Ramón, I was about to create a new topic for my question, but it’s maybe better to post it here, not to make mess. Have you thought about adding a cw decoder function in your

Dear Muthu, please read this new thread:

Hola, I have prepared a new batch of Raduino32 PCB with some modifications and improvements: Some components have been relocated. Since there are already stocks of the Si5351 chip, it has been

Raj, You’re right, I don’t have eyes in front of holes. Looking at your diagram, it’s actually simple. It’s like a diagram avoids long speeches. thank you.

Yes there was a resistor change in the mic amp that increases the drive level and offhand I can’t remember what value and which one it was. My notes are in storage I’ll have to dig them out. There

Howard, I have not installed the N8ME software, but for the other version the calibration EEPROM is not changed, so recalibration is not needed as long as you use the same Nano. If you change the

That's what I thought it was. The previous owner has it turned all the way up and I'm only getting about 4 watts on 40m. I've ordered the 2N2222a metal cans, so will see how that helps before I go

One other question: Is it necessary to recalibrate frequency and BFO after installing the N8ME firmware, or is the original calibration retained? Thanks Howard K4LXY

Farhan Could you instead upload a zip to the files section here on groups.io ? /Niels

OK so the RPi 40 pin header schematic was wrong above... Attached are the known pins defined (from my understanding), but where to route the encoders/buttons etc. Code and schematics I have do not

Stan, Start with bias presets RV2 and RV3 at fully clockwise.. which is Zero in the uBitxs layout. Key PTT and measure current consumed. Advance one preset to get 100mA more and the second another

Thanks for that info, Raj. Very helpful! You’ve given me a great place to start and PA bias needs to be set regardless after replacing the IRF510s. The primary reason I bought the uBitX was to

Hi Farhan Thanks for the quick response, so my understanding of the pinout on the RPi 40 pin header is as attached, can you confirm the pins you are using for the Si5351 I2C bus, plus the

Hi Niels I too have this codec breakout board and have wired it as above, but am confused regarding the Si5351 code as it references SDA as defined as 23 (GPIO23) and SCL as 22 (GPIO22)? good luck
