Hoo boy, the joys of programming up a synthesizer for your rig! I've been doing a lot of programming on a Si5351a with I & Q outputs recently but haven't had it actually connected to a receiver much a

Boy, a lot of good info in there Jim. Thanks for taking the time to put it all together. One point I'll take a bit of an issue with is the suitability (or not) of ferrites such as type 43 for antenna

It's a tough request because there are so many books and what any individual is ready and wanting to learn on a given day varies so much. I'd second EMRFD as a good one. The Art of Electronics comes t

I built one Terry. I probably lagged the rest of the group by some time, but it was a fun build and resulted in a really nice rig. I looked in my folder and have everything from originan 1993 informat

I'm very sorry to hear of Bart's passing. He was a good guy and I always enjoyed seeing him at OzarkCon and working him on the air. 73- Nick, WA5BDU

There have been several questions like this over the past few months. QRP-L seems to be running on autopilot and the moderator has left the building. Whether permanently or not, I don't know. Unfortun

That still sounds a little weak to me, although I'm not an AM expert. A -73 dBm signal is S-9, so you'd think it would be pretty solid. No doubt the % modulation of the signal would come into play. It

I always figured that with the light bulb thing, most of the radiation would be from the coax. But maybe not. There was an article in QST years ago (July 2000) called "Everything Works" where a guy ma

I've found the same thing, Curt. Using ExpressPCB to make SMT toner transfer designs, the footprints that are standard are no-doubt fine for machine assembly or paste & heat, but if you are using a so

Good Ozarkcon! Thanks to all the volunteers. The Friday evening in-hotel QSO party was better than I’d heard it in a while. Paul N0NBD operated WQ5RP. There was a big crowd of stations on 40 meters. I

I'm giving it a shot too. My only possibly suitable laptop is a little notebook I put Debian on a couple years ago. I forgot everything it taught me about Linux so I had to spend a whole day learning

Back in the 70's, owners of less expensive banjos would talk of upgrading with a Stewart-MacDonald tone ring. Never did it to my RB100 though. Excuse the digression - couldn't resist. Nick, WA5BDU

Sounds like it would be an interesting experiment. It would definitely put the heat on the presenters to put the maximum content into their allocated time. 73 Nick, WA5BDU

It's both and it depends on context. If someone says he's running 1R5 watts, that's 1.5 watts, not 1 received OK watts. If someone responds after your transmission beginning with RRR, it means "I copi

The idea of not having enough voltage on the electrolytics is interesting. I recall once considering what the ill effects might be of using an electro in an audio circuit where there was no appreciabl

This reminds me of an article in QST in July 1963 called "Euclid and a quart of resistors". It showed how to take a quantity of resistors of a single value (say you have a quart of 47 ohm, 1% resistor
