Hello Bob and Hans, I was very surprised and ashamed to say my WSPR test transmission result as before. Your QCX(3W) and 6m long Vertical works great job I think. Sorry but I did not modify my QCX to

BINGO! All better. Thank you Barry and now I'll be able to update once my QCX gets here and I get it built. Jim - W0EB

Install WinAvr. Launch it, that will install the missing .dll thingy and AvrDude / Dudess will be happy. I too sun windows 10 Pro. barry

George, I'm a total incompetent when it comes to electronics... but it seems like clearly something is very wrong: a short somewhere, or an open circuit, or one or more damaged components. If you

It can be done. However, you are going to have an impedance bump at the connection between the two. This may or may not make a difference. It certainly un-neatens the job. If you are short only a few

Hello I have had a problem winding the transformer T1 and now find I am short of wire. I do have some wire of a slightly thicker gauge. Would this have much effect on the characteristics of the

no load on the 3.3 volt rail, and it didn't occur to me to try the scope. I'll rig up a load resistor and hang the scope of it. -Justin N2TOH

I should have said I haven't been able to find a version of libusb0.dll that my 64 bit version of Windows 10 will install due to claiming it contains a virus. Haven't been able to find a download

Hi all, Have been working on getting zero drift and frequency stability on one of my U3S units. So far... - Added a small heat sink on top of the 27

With nothing else to go on, the only action I could suggest you could try is to disable "driver signature enforcement". I do NOT recommend you take that course of action (unless you fully understand

Hi Justin, when I have had something similar, I have looked at the 3v3 output with a scope.  An output higher than the input usually indicates an oscillation somewhere.  I assume you have a load of

One more data point - the signal generator seems to work just fine. Dan, n0da

Powered up 80 meter QCX and LCD looks good. First step in alignment is 8.7 Peak BPF, but when I select this option I do not hear a 700 Hz tone in the headphones, and adjusting C1 does not move the

What is the *exact* error message you are getting ? At the moment you are saying the equivalent of "My car won't start" (at least you have given the Make, Year & Model, that's a good start ;)

Hello Jim. I run AVRDUDESS with the USBasp or USBtiny on a windows 10 64bit machine. It can run on your machine. Kind regards. James.

Jim, Does the Arduino appear as a USB device in "Device manager"? Has it a driver? Zadig http://zadig.akeo.ie/ should install libusb with a certificate, it is usually used to assign a driver to a

Did you try using Zadig to update the driver? I have been using a Win7 machine to do my updates but may have to try this on my 10 Pro64 machine. I just watched a video of someone updating
