I believe there were not supposed to be 'spares', but parts for other bands. Was the loose one you tested actually marked as a 390 pF cap? What did you measure it with? I presume what you stuck in c25

Way to go, Dave!? Your many studies, experiments, engineering, and skill have generated quite an achievement!? I missed it this time around because I was fussing around with the next version of my

This looks a bit like the Morserino, which I'm also excited about: http://www.morserino.info/morserino-32.html 73 de AC3K

Just to be on the safe side, I ordered new silver mica's for C25 thru 28 to go in my QCX 20 if it ever gets here.? 73 Jack KZ5A

Did you check the markings on the caps fitted. Component quality is very good these days. Did you check your tester against a known good capacitor. What are you using to test capacitors, is it a DVM

Hi, I am happy to bring my equipment back to FDIM again this year and set up in case folks want help with surface mount component soldering or other soldering tasks. If so please let me know. There is

think I have narrowed the issue to the caps at C25 and C26. They are supposed to have a value of 390pF, but when I tested a spare one that came with the kit, it measured 55pF. ?I already ordered some

Thanks for you very helpul and comprehensive answer, Steve. I will experiment a bit as time permits. I have groundwater at about 1,5m below ground, so that should be an asset. A few days ago I

I think that question was answered at the time of commencement of the PA sub-module, See:- /g/QRPLabs/message/27274 Alan

Wow ... U3B-25 completed its 3rd lap of the globe ! This thing is the Energizer-Bunny of pico-Balloons !? Congratulations Dave.? Cheers Michael VE3WMB

The 10W HF Linear PA module is now available separately for sale, does this mean I can buy the QSX kit (the moment it is available) without the PA so I can work ahead? I expect this module takes

Hi Steve, I have about the same feelings about the QCX. Thanks for sharing yours. What catched my attention is your fence antenna. I have kind of similar restrictions. So far, I use a temporary wire

This project is the subject of my FDIM talk, so I will likely make it and the code available after that (mid-May). It is also in Chapter 7 of the new Projects book Al and I are writing. We plan on

Hi Paul. At the moment the firmware does not change the local date correctly. Living in the UTC timezone and on standard time you've been lucky until this time change. The good news is that Hans is
