Good morning, Thanks to everyone who responded to my new guy question. I appreciate it and hope to give input to the list as time goes on. Have a great weekend. 73 Steve N4TKP

Chris, Ummm... stronger stations with the plates disengaged? Well that would work to attenuate their signals. For the weaker stations you should find a very pronounced peak in strength as you tune

well, its done, and it works quite nicely. Thank you for the responce. The cap I used has two seperate setts of plates, so I hooked up a small toggle switch, so i can run both sets or just one. I

That is a very nice looking loop. --- lockmanslammin@... wrote:

Thank you man, thanx for the kind words, and also letting me know I was on the right track. I will let you know how it works if your curious, Chris

Daniel, With the kind of bandwidth you are getting on 40m I would say the loop's Q is seriously degraded. You should only have about 15-20 KHz between 1.5:1 points. KI6GD's loop calculator predicts

Chris, Sounds like you made a very fine loop, indeed! The only thing I would have done differently is to make the coupling loop about 1.5" to 2" in from the main loop winding. That helps improve

I was able to get the antenna to tune up on 40m, but had to switch from magnetic coupling to a direct matching system (shield of coax at center point of loop tubing, and moving end of coax along the

Daniel, Very interesting post! I like your idea for the tuning capacitor. I thought about a somewhat similar approach using a larger diameter copper pipe sliding back and forth over the gap in the

I just dug up one of those little square loops outa my junkbox and took a look at it. It has 6 turns around the circumference (about 4" by 5") with the remaining 3' of wire twisted together at about

thanx for the reply, while I was waiting for the reply I ended up making one, maybe you could tell me if I'm on the right path. It is 19" X 19" square with 18 turns on it, both begginning and ending

This is Bruce (not Brian) Carter. My opinion on those little loops that come with receivers is that they are probably NOT tuned loops with the varactors or tuning capacitor inside the units. I

I just joined the list because I've been wanting to build a compact transmitting loop for many months now, and I was met with good success late last night (around 12-1 AM, while I was waiting for

Chris, Check out Brian Carter's web page at... <http://www.mindspring.com/~loop_antenna/> for a very simple and effective AM loop antenna. What most people don't realize about those AM loop

Steve, I have successfully used receiving type air variables for QRP operation at 2 watts output. For 5 watts you should use something with 1000 to 1200 Volt plate spacing. For 100 watts you will

Lui, You didn't mention what floor your apartment is on but since you use the word balcony I assume that you are not at ground level. You can use the balcony railing as an antenna. If you have

These were posted on the earlier loop group so I thought i'd post them on this one. The RF connector is a 75 ohm cable TV chassis mount. It goes to hookup wire that is wound 10 turns around the

This page,new to me,caught my attention because in addition to good info on loop & capacitor constuction, he has used a BBQ spit motor for remote tuning. Hmmm,two of them might allow even a novice to

Good afternoon, My name is Steve, N4TKP located in Bartow, Florida and I am new to the list. I am interested in building and experimenting with small transmitting loops. I have found alot of
