You provide so much good content. I already know much of this stuff, but never enough, and you provide some more good insights, tricks and tips, and summaries of a lot of practical experience. I also got a good chuckle out of the Armstrong rotor. I used to do that with an 11 meter band, 3 element beam in the foothills of Colorado years ago at the peak of the solar cycle. Memories. Thank you.
Can't concentrate on the antenna build because of dreaming of having that receiver. That is on my list of receivers now. Thanks. Just what I need another receiver....lol
Your outdoor setup reminds me that the best place to store those clip-on ferrite suppressors is on a feed line - they're easy to find when you need one (no hunting in cupboards or on shelves) and they might even be doing something useful!
Looking forward to the tuned variant. Must be awesome performance. Could part 4 be about the type with a pickup loop inside the loop ? You are amazing in explaining things. Thank you so much.
Interesting and much appreciated. Thank you Mike. I am certainly considering a receiving loop. Whenever I travel even a short distance out of town and operate QRP/P, I am usually amazed (and saddened) at the stations I can hear that are well below home QTH noise levels. Therefore, I have to wonder if a properly designed RX loop might educe many of these signals currently lost to QRM?
Great video Mike--really enjoying the Loop series. Still wondering about using balanced line as the feedline and if we lose the noise cancellation effects that motivated us to use the loop in the first place. Speaking of which: Anyone got any sources of low-cost TV twin lead(preferably like the deluxe Radio-Shack 20 ga. one? Guess I shoulda stocked up in the 60's! I have a VERY NOISY neighborhood and have a regular 80M sked that I'd sure like to improve my RX S/N ratio! Will we end up with any design recipes that would allow us to go after a specific band?
Amazing work! Waiting for the next installment with excitement. Do you think you may consider adding a pre-amplifier for a receive only loop in the future??? I bought a Chinese receive only magnetic loop antenna - an MLA-30+. And I would love to see some good old American ingenuity surpass it in quality! I am an avid fan, as I live in an urban noisy environment for HF reception, an would love to build one myself. Thanks very much, and the warmest regards, Lance ZL3LAD.
Thanks again for another excellent and thought provoking video. I have the frame of a 12ft circular trampoline and had the idea of running a copper tube in the centre of it, held in place by insulation foam with the outside tube (approx 2 ins diameter) as the shield. From your experiments, 12ft seems too big to be effective with regard to nulls? Perhaps I should use it for the frame of a wire mesh satellite dish instead? Any other ideas for it?
Mike , great stuff, will be looking for the results of the 0.1 Wavelength tuned loop ! Wonder if you are on 160 m ? I would like to get on 160 this Winter , lost my other Antenna . Good luck ! 73, Jerry K9UT

Let's hope that Cycle 25 with break the downward trend. It is already showing promise!
Great series so far. Thank you so much

What is that receiver? Looks real nice.
Watkins johnson hf-1000 or wj- 8711. From what I found so far
It is truly the best looking radio that is not a military radio I have found lol
This very interesting stuff many thanks for your trouble doing these learnings
I like very much this video series about loops. Very well explained and demonstrated. Thanks

Ahoy Mike, You're sending me LOOPY

is the AGC increasing as the signals are nulled which causes the noise floor to appear to increase?
Yes. Only the meter really tells the truth.
