The raduino turns on when powered directly. My version is 5.1. I found this interesting as all the troubleshooting guides I've found were for versions 3 and 4. Is v5.1 very new? Could I be

Remove the // in the top entry that start with //xstr I think the second like was already commented out.

I think I was one of the first to add an 'all-in-one' USB solution inside a uBitx with a small 4 port hub?? I also did the 'cut the red wire' at that time. I had posted it here...

The nano "head" with screen was not connected to anything. I just had the screen plugged into the board and the arduino powered via USB. I adjusted the pot and it's still worked. Next time I switch it

Joe, I think I found where you commented out the max Frequency.? In the pre-initialize events "vis tDecode1,0" . changed that to vis tDecode,1 but had no impact.... Was there some reason you decided

Joe, Thanks, obviously enough of a newbie i didn't recognize a comment. :-) Perhaps I need to go thru the tutorial before i do any damage. ... 73 Mark

When you say maximum frequency, do you mean the numbers in the upper left of the spectrum screen? I turned that off. I can show you where I commented it out. And maybe other things like color and

What exactly were you doing when you fried the first nano?? Was it still connected to the Radiuno?? Other than the display, were you able to tune around or do anything else?? Did you try adjusting

Joe, Got the two screens running, 3.2 + 5 and standalone signal an analyzer. Trying to tackle something simple at first - When the spectrum is displayed on home page, the maximum frequency is not

Hey All, So I got a Bitx40 as a gift and wired it all up, I can hear static radio seems to be working but no display. I uploaded new code to the nano and promptly let out its smoke. I connected

Don, Something doesn't make sense.? I hate it when people say it works for me so it must work for you, but I am going to be that guy.? There should be no problem using a USB sound card and a CAT

hello! ?When i got my sound card dongle and cat control working each in their own USB port on my Win10 laptop, I almost fainted from uBITX joy. It is reliable and works well. So time to move on.

HI all. The AD3807 has a liniar responce 1dB but it is also logaritmic. Could this be the reason? Rob PA0RBL

Does it use a crystal or ceramic resonator for the oscillator? -- N5KBP

Farhan, Thanks so much for your help and thoughts. I assume you are seeing the same thing on your end? I want to make sure this isn't just because of a single unit or bad measurement data. Is there a

I guess, we need a better post mix amplifier? probably increasing the current there will help? I am not sure where this non-linearity is coming from. I suppose at least 70 db of linear range will be

I had experienced two cases of random errors. The first when I did not solder correctly the two resistors. The other when the jack contacts were not doing a perfect contact. Note that I am not using a

Looks like that 256 bytes of EEPROM is not a typo :(, it says the same at https://www.microchip.com/wwwproducts/en/ATMEGA4809 73 Goran VE6GPO

Yes...mini usb. Just to confirm the raduino is ok. Then, we can go after the wiring and main board

How do I hook up the 5v directly to it? Is it the miniUSB? I verified that all the pins are lined up for all connectors. With the power on, I verified that I have power to main board using the black
