Hi Allard, if I switch on ?= RADUINO V2.02. and Touch keyer OFF even I touch the two capacitiv sensors.

Ok, lets try this. Load Gordon's 25 MHz sketch. Find the signal on the HF rig. Edit the sketch to change the freq from 25 MHz to 26 MHz and upload. Is the signal still at 25 MHz or is it now at 26

Loading sketch after sketch hoping to get a peep out of the thing is a waste of time. If one doesn't work, none will. Go back to the troubleshooting video and work your way through the hardware to

No worries,? Vince. Yes...only thing connected is the usb

"Yes...I did this AFTER I reported here. So, it worked the night before last, Farhan's sketch failed, Gordon's sketch failed, then I retried the 25Mhz sketch and it worked again. Note that I loaded

Farhan posted earlier that he'll check into the missing raduino purchase link on the website. Are all wires (except the usb) disconnected from the raduino for these tests? I know I'm getting redundant

I noticed that as well.? The "Wiring UP" schematic on both pages is incorrect and needs to be corrected or there will be many "Dumb" questions regarding why CW won't work with standard keys.? Also,

And Gordon.... I don't consider it a bad thing if the raduino is bad. I consider it a raging success. I went into this thinking something was broken. If we are able to find the broken thing so it can

Very helpful suggestions , all!! Sent from my iPhone

It is hanging in the air about an inch above anything...supported only by the USB port. I do this with all my little boards if I can...make sure they can't get grounded in bad places. Yes...I did this

I've also discovered that with a small speaker like you have in the picture, you can take a thick rubber band, wrap it around your head and wedge the speaker between the band and your ear. The

Ok, replying to myself here. Like I said, I'm not convinced there's anything wrong with the Si5351. Is the raduino mounted in the case or is it out by itself? If it's installed, remove it so we can

Snap-e rat traps are great Gordon! I would recommend inspecting the raduino properly without display for any bad solder or track cut or such! It has travelled a long distance. Raj

Hi Franz, What help exactly do you need? Did you follow the instructions at https://github.com/amunters/bitx40/blob/master/operating-instructions.md What problem (symptoms) do you have with the

First my apologies for perhaps asking question that answer is commonly known. Also please note that I have zero experience re either the Bitx units OR Arduino based rigs... So, I can understand that

The part is Si5351. Yes you can replace just the chip, but you'll need to be able to do surface mount ICs. You can get the chip from Digikey for just under a buck. If you prefer Mouser, it's $1.15 ea.

I need help for the correct valies for capacitives touch sensors Franz DF5GF

Alex ? You are correct. I'm using one of those inexpensive voltage/current/power/energy LCD displays that has simply +/- in and +/- out. I'm concluding from it's behavior that it's measuring current

That is what I have done. ?I have a small external communications speaker, I can place it somewhere comfortable to hear, or I can drop the audio level and the noise and hold it against my ear, or I

Double and triple rats!!! Before I hurried after work, I was able to take a plain old 12 inch insulated clip wire, and put some tape on the far end and drop it amidst the morass of wires near the
