Oui le Inner-Loop doit etre 20% du Outer-Loop, le calcul est important. Content de voir que tu apprecie ta F-Loop 2.0 Super et merci pour les bons commentaire! 73

I wish I could have more time, thank you for the nice comment! 73

Yes at 205 inches the top band is 20M. For the barrel connector, may be the Power Compensator plays a role, in theory the inner/outer should not make contact. Glad to see you are using Mag Loops, thanks for the comment!

Agree. The goal was to compare how weak signal compares with native audio, which is what most operators use. The audio part could be improved by using better speaker/amplifier/equalizer/compressor/noise reduction.

Yes, actually hard to measure, but bigger Loop = bigger Bandwidth and more efficient for TX!

Congratulations and Thank you for being the 1K subscriber! To preserve a cage ensure enough space is available around the radio for both insert/removal. Good luck with your build! 73

Salutations de l'Estrie! 73!

Salutation Gérard! Bons contacts sur les ondes! 73 Frank

That sounds great, I would like to see that! Thanks for stoping by!

I believe using a 1 inch tubular would increase the bandwidth, but a RG8 vs a 1 inch tubular is not much difference, some have tried with 4 inches tubular, I do not have those results. My 1st instinct is overall size matters more than thickness, but you can try and see and may be share your findings? Great question, ask for asking!

The idea is to use only 1 radio, either QRP/portable or 100W at home/car. Depends on what we want to do.

Ok. I got it. 😊 A good amp with tuner never gets old. Modern radios change like womens clothes. 😂

Hi! It is 37 lbs, see my new IC-705 Go Box this one is 36 lbs, Thanks ruclips.net/video/2YL12mOEn7w/видео.html

Ref: "two small extention leads for the speaker and mic" that is a good idea!

Thank you Dave for the comment and also for providing excellent videos on your channel.73

Hi Kevin, Thanks for the nice comment, it has now become my main everyday radio. Keep up the good work for your endless imagination for new antennas ideas, awesome! 73

The "Boost" version as per their web site: "The unique GVB-8 Boost charge controller with MPPT allows a lower-voltage solar panel to charge higher-voltage batteries. Want to charge a 24 V battery with a 36-cell (12V-nominal) solar panel? No problem. A 48 V battery from a 60-cell (20V-nominal) panel? We’ve got you covered. With 99% peak efficiency and the ability to charge with as little as 5 V of input, they are the industry’s most efficient voltage-boosting controllers." I am not sure I am benefiting from that with my portable 60W solar panel, but they make very good controllers. Hope that helps. Thanks for the question and nice comment, good luck with your next project! 73

@@VE2FGJ Thanks for your reply. I'm testing the 10A lithium controller on my 23 Ah battery pack/go-box. Right now, with our cloudy skies and low level sun, it looks like I need at least 18Vdc output from my SunPower 100W and 50W flexible panels to start charging (and mind you it's only supplying ~50-100ma of charge current). So, I think I'll give the Genasun 8A Boost controller a try next to seeif it it can do any better in these low light conditions... 73

Thank you, glad you like it! 73

Hi Renaissance Man, Reference: "...like a centre tap on a tuned circuit" while I can imagine that, I have yet not found related materials to explain that kind of direct/indirect coupling that improve performances at higher power. Thanks for your comment.

@@VE2FGJwell you would be connecting the two circuits at the 0V points….assuming the feed to the loop was balanced…common mode choke on the antenna end of the coax would see to that I try to tune my loops so they are at resonance with the smith chart in the middle showing the lowest Xl and Xc values I can dial up. I then note the impedance at that point and adjust the turns ratio and coupling to match. Tighter coupling does _pull_ the resonance and impedance of the loop. You would loosely couple a free running LC RF Oscillator to the next stage as any loading would cause the frequency to move. On my VNA I have SWR, Smith, phase and S21 Logmag. I look at SWR with respect to the Smith chart and phase with the idea that understanding the Xl /Xc components of the antenna at that frequency, let’s me know what I need to do to achieve resonance. (Logmag on S21 let’s me quickly check cables for losses) What does the smith chart on your VNA show with the loop connected vs isolated ??

@@MidlifeRenaissanceMan Wow a lot of things I have not delved into, I wish I had a VNA to experiment with and without the center tap (barrel). I appreciate your detailed explanation, hopefully I will experiment more in the future. Thanks.

@@VE2FGJlate Christmas present. Get a NanoVNA. Best $50-150 you’ll ever spend. Seriously. If you’re working with any sort of antenna, a NanoVNA will show you all those important bits that you never think about. Get one, check out one of the numerous videos on setting it up You want to see SWR and the Smith Chart as a minimum. Smith chart tells you complex impedance so whether you’re too short or long as well as impedance at resonance. My mate was screwing around with a fan dipole on 40 and 80m. Couldn’t get it to match up kept lengthening it but never better than 2.5:1 I came over. Stuck the NanoVNA on it with the smith chart. Because of the proximity of the ends to ground, it dropped the impedance. It was also resonant a little higher up, so we unfurled one end to lengthen it (he hadn’t cut just yet), and folded in the other end. This pushed the feedpojnt off centre and raised the feed point impedance at resonance. It was still a little short, but fine for the voice section of 80m with an SWR of 1.4:1 at the top end of where we can operate Knowing the impedance and the complex impedance sorted that issue out. All with the $80 NanoVNA with the big screen I picked up used and replaced the battery to fix it’s random issues.

Hi! Cable is LMR 400.

Yes the IC-7100 is a good choice, in my previous Go Box I had it with a SDR as you mentioned. Good luck with your build. 73

Thanks for your comment, I opted for portability, a vertical is the simplest option, any fully resonant antenna will perform well. Glad it also works well with your antennas, good contacts! 73

Hi Nigel, awesome! Have fun! 73

The box comes empty, you can use any shelves you want, vented or not, it is not critical, there are various types and possible configurations, what is shown is one possible way, yours may be different. I have build my own IC-705 Go Box and used different shelves and drilled holes when necessary. Hope that helps! Good luck on your build. 73!

Hi Mike, I do not CW, I believe both radios are good, it is a matter of preference. Over time I have found that the choice of antenna and location supersede any radio choice. Hope that helps. Thanks for the comment. 73!

Hi, the F-Loop 2.0/3.0 capacitor is a 10-365 pF and 5-182 pF. There is a switch (A/B) we can toggle to switch between single/dual gang capacitance. To build a MagLoop I can suggest to use the least Capacitance and rather increase the Outer-Loop size to match the highest Band you will be using the most. As an example, in my latest video I chose a 205 in loop to use the 20M band with 90% efficiency. Bigger is better for the top Band you want to use, compensating with a Capacitor, results in lesser performances. Hope that helps. 73!

@@VE2FGJ Thank you for the tips. Makes things much clear now 🙂

Yea, they are expensive, but they are good and proven. Building your own requires a lot of research and understanding, may be trials and errors. I have build many loops based on a commercial Capacitor. Loops are fun and surprising! Good luck! 73!

@@VE2FGJ Thank you for your encouraging words. :-) Everyone has to start somewhere... Chameleon also did so let me start and see where it goes! 🙂

Great! Glad you like it! 73

Hey Gilles, thank you very much, I appreciate it! 73

That is great Tracy, thanks for the comment and good luck on your build! 73

Thank you John, glad you like it!

The tuner is in bypass mode, it only shows SWR. The flickering you saw is because we did not use a choke at the feedpoint, some RF comes back.

We knew that and did short the cable's PL-259, we also shorted the F-Loop's SO-239 internally. Thinking back it may have been caused by not using a choke at the feedpoint, we used a 100 feet coax to stay away from the antenna. So many things to try...

Thank you John! West coast to East coast! Wow! 73!

Hi AJ, Wow thanks for the super nice comments, I did spend too much time making this video... I am glad you liked it, hoping it will help others with their Mag Loops and experiment for better performances! 73 !😃👍

@@VE2FGJ absolutely this is really really cool stuff. I have a chameleon myself but haven’t used it much because of the inefficiency!

@@aj2isotadxing Please try boosting the loops sizes, it can be impressive! Thanks 73!

Thank you glad you liked it! 73!

Your are welcome thanks for the comment 73!
