Rob, I assume that it is copyrighted. However, I don't believe that any of the lessons ended up referencing it, so you are probably fine without it. It is a great resource and well worth the purchase.

Jerry...You will want to make sure you do 2x the skin depth if you use a strip...the rf will be on both sides if it is a single strip like mine. The lower the freq the thicker you have to go. I will

From web calculators, even with 5w into a mag loop there will be on the order of 1kv across the cap. And it goes up from there with the square root of the power. An air dielectric repairs itself, so

Hi, I haven't been reading this entire thread so I may have missed some statements. A daily driver is the car (or truck) we drive to work every day. And to grocery store. As opposed to a precious

I am not a "critic" of your efforts Kurt - I applaud them.? Further, let me help you.? Please see this link:

You should cherish your critics because they make you better. Sorry if I got hot under the collar, Kirk. Thanks for the link to the controller...good stuff. Shirley...great point...I mainly care about

I wish to 100 percent endorse the below email !!! Merry Christmas -Diz, W8DIZ

Kurt, lQQks gQQd Thanks for sharing I dabbled a bit with homebrew STL and always considered WSPR one of the best tools for both signal strength and directivity reports. For example.. Rotate STL 90

A great deal of hard earned wisdom resides in those words. There are many, many ways to make an antenna that's worse than a dipole, and all of those that are better than a dipole are at least an order

Again, there's nothing special about the NorCal version of these docs. The originals are on my qsl web page. This is the site that was used during the original class back in 1997. All the authors (me

Nah, don't give up. I'm quite curious as to what you come up with. Experimentation is the best part of this hobby. Don't confuse advice from experience with a personal attack. Sometimes stuff works,

You're doing your own thing. Understood. Enjoy. --Kirk, NT0Z My book, "Stealth Amateur Radio," is now available from www.stealthamateur.com and on the Amazon Kindle (soon)

You can use WSPR for antenna testing for other modes. Just cut your output power to compensate for its power efficiency. Use at least 20dB less power than you would for CW, so if you're trying to see

Well hell...you are telling me I could have done all this work in my basement and not the kitchen table? Wow. My wife will be happy to hear that. They really have a racket going to claim WSPR is good

I get it. I'm not trying to stifle experimentation. I simply want to steer you toward the best resources. Self-resonant mag loops made from strap (where the insulated ends overlap to provide the C to

Hello Kirk, I think you might not be seeing what you think you are seeing. I really made a big mistake posting here. I wish I could delete my picture. If anyone reading this knows how to delete photos

I too am curious on the details of why teflon is not a good choice. If so, homebrew air variable caps could work, they just have to be big enough for a suitable air gap. It's a hobby, and an

Sorry, Kurt, A "daily driver" is an antenna that stays in service for long periods of time and is used daily (as opposed to something whipped together for one reason or another). It's a motor vehicle

That controller you link to is similar to what I have in mind...but an iPhone would be the interface to the user. ...but when I have someone with 30 years of knowledges telling me to give up...I’m
