Andy, Interesting your comments. I just tried and wsprnet.org seems to be working quite well at the moment. Earlier today it was on and off. I think the servers are in the US but I don't if there is

Never thought I'd say this, but I think WSPR is now dead. wsprnet.org must now rank as the most useless website on the planet, alongside microsoft.com and yahoo.com. Time to move on. 73 de Andy

Hi Chris: Actually, things like the Si5351 chip used to scare the stuffing out of me. With 76 laps around the sun under my belt, the eyes and hands aren't what they used to be. Still, I got a hot air

I think it's a personal choice. Just like your favourite OS or Auto brand. Much is discussed about what construction to use, the IC socket supplied for the uPC in the

Do you see supply volts on the PA FET(s) Drain pin, It's supply is fed off a separate pad on the PCB maybe you have wired it for something other than the same 5v supply for the

Hello Larry, Tuesday, November 12, 2019 Personally I would like to see the cost go up on Hans' remarkable creations and they be designed to take sockets for all the devices, the surface mount ones

Hi Nick, Q1: Has anyone successfully repaired a QCX after such and over voltage? If so, what was the list of components needing replacement? I am surprised that nobody has said

I've used machined pin sockets in my career as an embedded systems and software engineer for 40 years.. Typically I was working on prototype boards doing board bring up or firmware development, but

I've used both, but stamped most of the time, and no major problems with either. Jack, W8TEE

Hello Emory. I’d say it was a good place to start. I’m fairly sure sure that one BS170 is much the same as any other. They’re cheap enough in general. I’ve a few spares as I’m sure

I have always used sockets for years and have never had a problem with them. However, I have always used MACHINE sockets and never STAMPED sockets. There is a difference. Lee, w0vt,

No output from my U3S? I can hear a very faint signal on my HF rig but no RF out into two different meters into a dummy load. Tried several LPF on different bands, no change. It stopped output

I avoid them for anything but programmable devices like the 328p. Over the last 40+ years I've suffer from sockets that failed over time. I use machined pin sockets when I have to or think its good

Why don't you just buy one of these: https://www.amazon.com/TinySine-USBtinyISP-AVR-Programmer-Arduino/dp/B00N8EVQ30/ref=sr_1_9?keywords=arduino+programmer&qid=1573578660&s=electronics&sr=1-9 Or

Thanks for adding me to the group! I hate to admit how little experience I have, but my purpose in coming to this group is to ask for help in fixing my QCX. And by “help” I need to ship this

Hi, I am considering updating the firmware on my two QCX's...... maybe after a stiff drink or two ! I will probably use the arduino uno method as I have a couple of these spare When looking for the

Hans I realise that I could be regarded as some sort of CW weirdo for using Ultimatic mode. But there's a similar line of reasoning that suggests anyone using CW in this day and age is a bit weird

I just completed my second QCX build and this time I used sockets for all the ICs and left longer leads on the transistors. I have used it on several SOTA hikes and it is working great. No problems

Greetings, I have made three keys in my relatively short Amateur Radio career. The first key was a brass straight key with a built-in Code Practice Oscillator (Twin-T). My second key was made from
