Yeah, fun for sure. A few years ago I was trying to come up with a rig that could be fun for room-to-room QSOs such as at OzarkCon. I figured 10 meters or maybe 6, so a full sized antenna could fit in

Way to go Paul! I made two in-hotel QSOs. Getting a couple in the log is part of what makes Ozarkcon for me. I should have brought some semblance of a 'real' antenna like you did. I had a small loop w

I made my first FT8 QSO a few days ago. I jokingly said I didn't know whether to be proud or ashamed. :-) For downloads, you mostly need the one package. Everything is there. I did make the mistake of

Here's a DDS to tube type TX thing I did a few years ago ... http://pages.suddenlink.net/wa5bdu/dds_amp.htm I think just to drive a tube, I might just drop the 4:1 transformer at the collector of the

I was also impressed enough with that article to vote it as my favorite for the month. Reminds me of a few years ago at OzarkCon when I was doing the "in hotel QSO" thing and worked Herb, WR9H, who to

It was fun and a bit surprising to find the hidden TX. I was going to borrow a small directional loop from N5IB but couldn’t find him in time, so I went to my room and turned on the KX3 with its dummy

I’m really happy to be part of the toner transfer presentation, but N5IB is actually the lead man on the effort. I’ve gotten into this discussion late and have seen some good pro and con opinions. The

Hey folks, If you’ve got some time and it’s not too far, drop in on our hamfest this Saturday. This is our 25th and we usually have a pretty decent one. We’re moving to a new, larger venue. Some nice

It’s a hard question to try to answer because there’s no one-stop resource. EMRFD as mentioned below is a good one. W7ZOI announced on the EMRFD discussion group recently that ARRL is discontinuing it

I recall seeing a similar scheme published in QST or Ham Radio a few decades back. Some schemes put a LPF on one ear and HPF on the other. More complicated schemes had two BFOs. A signal would produce

This thing can be an antenna analyzer. Scroll down to #25. http://www.qsl.net/k5bcq/Kits/Kits.html It definitely fits into the “ it’s no Heathkit” variety though. Pick your own enclosure, some pretty

“In many of the older boat-anchor rigs, especially in the homebrew rigs, the builders placed a small flashlight lamp in series with the xtal, between ground and the xtal to limit xtal current to prote

I’ll definitely be going somewhere. QRPTTF is one of my favorites. 73- Nick, WA5BDU

For anyone who might be interested, I put my PowerPoint slides for the phasing receiver presentation on my web site: http://pages.suddenlink.net/wa5bdu/radio.htm Scroll down to the bottom entry in the

I forgot to mention during my talk – yes, I’ll be putting the presentation and schematics and so on, on the web as soon as I clean ‘em up a little. I’ll post here after it’s done. 73- Nick, WA5BDU

Getting back to normal after another excellent OzarkCon. Thanks to all the organizers. Good to see a lot of familiar faces and a few new ones. On the way up, Jim N5IB and I stopped at the Buffalo Rive

Sorry for the repeat posting, but I forgot one stack of books and just added the photo. The one that’s too faded to read is “Circuit Analysis by Laboratory Methods” by Skroder & Helm, 1955. Don’t all

I’ve got several weird old boatanchors, a few not quite so old things and a bunch of books I’ll bring to O’Con if anyone wants to purchase. In order to show them, I’ve opened a Shutterfly account and

I’ve used RUFZ a lot over the years. Lots of fun. Boy, some of those long DX callsigns with the portable prefixes are indeed hard to catch – especially if they’re coming at you at over 50 WPM. I don’t
