Thanks for thinking about this, Arv, but don't be giving Hans ideas on a UPS - I am but one of a growing pack of slavering hounds baying at the Turkish moon wanting him to finish his QSX

Hi, I made a few years at a company and thrived there until new management came. Egos ran away and I left. In the following year that company disappeared. I am still around though :) 73, Bill

What voltage was the QCX seeing at the input terminal?

When I read the original post, my immediate response was to roll my eyes. As I read it further though, my opinion changed. I recognized an extreme attention to detail, and it occurred to me that this

Negative, Arv In other words... Hans hasn't considered such a thing. Also, Hans doesn't think it likely that he will... 73 Hans G0UPL http://qrp-labs.com

Alan, Maybe the 27 MHz crystal is poor, I don’t know. The picture from Brian shows about 50 Hz drift on 6 m. Or 1 Hz per MHz. Scaled to 10 m it would be 28 Hz and 2 Hz at 160 m which is close to

While I agree with the majority on the quality and value of the kits, I don't disagree with the original post either. Think of it as a request for incremental improvements. It might be nit-picky, but

Julian This situation might make one think of some sort of UPS. It could be as simple as a battery in parallel with the mains based power and using simple diode isolation so that power would be

Don't forget that TX from GPS goes to RX on QCX and RX on GPS goes to TX on QCX.

Hi Julian You have an excellently accurate imagination OM. I'd suspect RF getting where it shouldn't. Black magic. Grounds, power supplies, nothing is too sacred. I'd add a large electrolytic at the

Hi Bill, Congrats. Would you mind telling us about you multi band mod of the qcx ? What did you do to it and how ? 73 Manuel DL2MAN

My QCX-20 froze up this morning. I was running WSPR on my QCX-20. It had run through several sessions - probably at least an hour's worth at 10 min intervals. At one point I went over to look lovingly

Thanks for the replies and advice. So I applied 5v direct to the 5v and gnd pins, and the red light comes on and the yellow blinks and the green blinked once. So it would appear my homemade cable is

Opened here no problem, it's just a bog standard PDF file .

HI Paul: Yeah, I was only there for a week or so anyway, but it just showed me that someone's ego was more important than getting help improving their code. Not good. Jack, W8TEE

Jack - this is why some companies survive and some don't. You were probably lucky to get out, even if it was unceremoniously.

If this page: https://qrp-labs.com/images/ultimate3s/assembly_u3s_r3_a4.pdf is showing as Not Secure, then there are a few possibilities: 1) You're using a Very Old computer (XP/Vista?) 2) The

Relax guys. We've all had suggestions at one time or another. That's what these are - suggestions - not demands. It's what he would like to see if Hans is so minded to make the changes. Just

I have found extra bypass capacitors in a lot of kits, not just the QCX. It's a popular practice. As others have pointed out, it keeps the company from having to send out another capacitor if you lose
