Gerard, I have read in one of the threads that installing a filter and capacitor on the power feed to the Nextion screen (assuming that you are using a Nextion) helps in reducing the "click".? It is

Hello, Now I’m asking for your help. I have on my own homebrew? Ubitx, a beep "tic tac"? on my construction. This comes from the Arduino’s SDA and SCL signals that communicate with the SI5351

Jack, It was a quick answer We can of course compensate the loss due to the diode There are lots of schematics on the net Example: Electronique - Theorie - Regulateurs de tension (sonelec-musique.com)

There's no voltage drop across the diode? Jack, W8TEE

Dean, Thank's for your answer I don’t think that’s gonna solve my sound pb’s. But I’ll try to change it cdt

Evan, I agree with you. Now look my 5v regulation of my Arduino. It's the same that on V5, V6 etc. The test to do is to connect the USB port of the Arduino to a pc, and do not put power on the Ubitx.

Hi Gerard, Yes - it even receives weakly! I use CAT control and keep the USB connected all the time so I disconnected the +5 from the USB input.? I recently got a powered USB hub that lets you turn

Gerard, The internal 5volt regulator for the Nano is supplying the power to just the 5volt parts of the Raduino (or anything else connected to the 5volt rail).? This usually includes the display

hello, have you noticed this: If I connect the USB port of the arduino and I do not turn on the 12V power supply, the internal 12v-->5v? voltage regulator switches the 5v to the 12v input. He’s

This was just an example to show that the 100PPR encoders can be made to work.? Anyone who cares to can feel free to incorporate Jack's suggestion and make the code into a library.

Thank you Evan, Vic and Sergio, I have forgotten what software I installed since it I wasn't paying attention to the BITX40 for a long time. It was the first radio I was able to listen to a 40m

Dennis: Why not make pos a static int within the CheckEncoderStatus()? It's still allocated on the heap, but you remove it from exposure via global scope and encapsulate it within the method that

Hello Mark, I arrived at that comparison when chasing the Rx signal difference between my V5s compared to my V3. The V3 had a lower receive signal (even when using the audio section of the V5 to

Unless you are using different software such as Amunter's V2 which requires some significant hardware changes, the BFO is only adjustable by changing capacitors on the main board. Not that it is a bad

Mark and all I tried the opposite way to lower the values for my sound pbs. That did not change anything. On the other hand, it would be good to look with a spectrum analyzer at the 3 signals clock

Hi John, How did it improve the RX and TX?? I am interested to try it, and am wondering what you found? Thanks! Mark

Michael, I have never worked on a BITX40, So ai am using experience form the multiple version of the ?BITX I have worked on. I sound to me like you have a BFO adjustment issue.? I would think that

I have done this, and it's wonderful for battery and night-time operating.? I have added a pot to the front panel that also has a switch on it.? Whenever I just want to listen and not tune around, I

Thank you very much for all your input! The speaker is passive and the problem was still there with headphones attached. The main problem was in fact the power source. With a proper power source, only
