I got my QDX by TNT today. Shipping started 30th October. Within 1 Week. I hopefully will start building the QDX up next weekend. 73 de DL1SER

Hi All, Back in the day when Royal Mail had the job of getting the kits to you the loss rate was about five percent if my memory serves me well. I had the job of putting the parts in the bags and

Sorry to hear it. I notified QRZ. It's my second time this week. I just cleared out a shack for a man that passed away 11 years ago. His widow never stepped foot in it since he passed. Great finds,

It also says to cut the three lengths of enamelled wire to 20cm. I did this, then with the screwdriver turned it 60 times, to find it was only long enough to get seven turns, possibly eight with short

When soldering through hole leaded components i was taught to place tip of iron, pre tinned, to the pad first, wait for 3 seconds, slide iron to junction of pad and lead, apply solder then slide tip

As excellent as Hans' build instructions are, I feel there is one page which could do with a bit of clarification.? That is the one dealing with winding the trifilar transformer T2.? It is

I reached stage 2.11 yesterday before other matters intervened, so hopefully today will be the day... These hints may be blatantly obvious but here goes. 1.? My first step was to remove the four SMD

Pleased to report that my QDX is now also transmitting on 20/30 m.? Nothing beats old fashioned tracing of the circuit with an ohm meter to isolate and identify errors in eye - brain communication.?

Hi Wes Respectfully I disagree... What really happens in practice is that quite often you find that increasing the inductance does increase the output power. I see this all the time. *IF* an LPF is

You're welcome, Pat, and I'm with you on that hope, though I'm nowhere near as accomplished as he is, and I am only recently finding my opportunities as a servant of the community. John wasn't a very

Thanks for letting us know, Julian.? Very nice of you.? I hope my obituary is as nicely done as John's.

Well yes, if you pulled it down tight - as I do - then that will make it different to thread extra turns, for sure. Glad you're up and running. Maybe the time energized "dried out" those caps or

Thanks Mike. It's really a reciprocal process: electronics may be my trade, but I'm really new into amateur radio, so I'm learning a lot from you guys who have been it for longer, in some cases, than

Adding windings on T1. Cheaper? Yes. Easier? No. I pulled the T1 down tight when I installed it never thinking I would have to restring wire under it….. Glad I didn’t have to. Strange though…..

Julian, Great writeup and thanks for everything you do for the members of this fine community of QRP enthusiasts! This is by far my favorite Groups.io..... Looking forward to my QDX build. 73 -Mike

RIP Jack K3JAS

It falls upon me to announce that one of ours - John Palese, WB9JPH - is now Silent Key. He left us on Sunday October 17th. I was doing some work for John - building an 80m Plus that he planned to use

Revised comment: When you change the circuit to move the frequency where the knee occurs higher, you also reduce the signal suppression at the harmonic frequencies. Need to be careful there. -- VY 73,
