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

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

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

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

I got the same mail one week ago, no sign of it (in India!)

As I understood ALL uBitx to US is via Courier and to EU by post with option courier. I may be wrong!

Rats!! If you didn't find the 4.925 MHz signal, looks like something there really has a problem...... I also note that you sound like you're really knowing how to hunt for things now!!! HOOORAY

While driving back to town I suddenly remembered CODEVIEW..

Andy: That;s all right. I misread your 2nd instance as 500 ohms, not 50 ohms, If it is indeed 50 ohms, then a simple 1:1 transformer or LC match will suffice. That may not even be needed as there

John and others, Thanks for your replies and comments. These demonstrate that it is feasible and possible. Now, I need to do some research/homework and bring it all together. If you like, I’ll

Bob, Why are you measuring current in the negative line and not the positive line? This would eliminate strange grounding effects as there is only one positive supply lead. 73, Alex PA1FOX

EDIT...sorry, I'm reading 200Ω for crystal filters, not 2K.? It's only a zero. hi hi
