One of the best educational videos on delta loops I came across, very informative, concise, up to the point, thank you!

Great video! Is there a way to use a similar app for ANDROID?

The background music is distracting and should be avoided.

Most likely some radar but could be the stock traders but really doubt they would be on a seasonal band like 10m.

I'm having a new issue. When I fire up N3FJP's ACLog, my Yaesu FT-710 switches automatically modes from SSB to CW. One specific example was YN9H showed up in the DX Spotter on 7.164 SSB. When I went to contact him, the rig automatically switched to CW. I tried changing to SSB but the rig would immediately switch to CW. Here are 2 more examples: I tried to get 2 more DX contacts - 1) an SSB contact on 18.143 MHz. I clicked the DX Spotter and the rig switched immediately to CW-USB and would not go to SSB and 2) a CW-LSB contact on 7.010 MHz that the rig would only connect to with CW-USB. When I tried to change to CW-LSB, it wouldn't accept the command. I don't understand why. I've checked the Rig Interface settings and tried a couple of variations, but nothing seems to help. When I shut down ACLog, the rig works fine. Can you help? 73, Ken KN2D

Thanks for making it easy! Trying to get ION2G to work.

I have Heil PR-40 mic I turned off Bias but left Pre on 20DB Mic gain ended between 15-20 and Compression at 20 I’m getting audio reports If I turn Pre Amp off I have turn mic gain near max setting - So I guess it’s ok leave Pre Amp on Joe in Alaska KA2ZSD I hope you make more videos I could not find Bias and Pre Amp controls till you showed how double tap mic setting in TX menu I find K4 manual does not go into good detail,Like Yaesu and Kenwood manuals Thank you

Looks like a shape of a digital QAM carrier used in cable TV's down and upstream, but the bandwidth is to narrow.

It's over the horizon radar from Iran. It's been coming and going since the Iran/Israel escalations started.

Wow - very strange - I've never heard interference sound quite like that. I've heard a lot of other types of interference but not quite like that. Get a yagi and see where it's coming from? Local factory or industrial process possibly?

nice

I'm sure I experienced this interference on 29.6 FM in the UK yesterday. It would have been at about 11:40 UTC on the 17th November..

So i know what it is, We have the exact same issue but on a 27mhz in the UK. Turns out to be car chargers! they have a 100% cycle rate with no breaks in transmission which is illegal in the UK! EV charges are going to be the downfall of radio imo!

I've seen enough alien invasion films to know whats up, hope you stocked up on toilet roll.

I've seen and heard this on my SDR for about the last 10 years, I started looking into it. I found a website many years ago talking about HF internet data eg:Ship to Shore , there is one thing I can tell you. What I've noticed is these strange noises are very time accurate. Another thing you could look up on the internet is Balloons in the southern hemisphere !! Don't worry these aren't local to you..

Sounds like some kind of industrial machinery like an inductive welder of some kind. Waterfall displays have brought a lot of this type of QRM to our attention we used to ignore, before. It is so wide in its bandwidth, that it does not resemble a data transmission. I see many things on HF. There is one thing I have seen several times that has a high amplitude that goes all the way up the RF spectrum in a very fast series of pulses in about 1 second. It looks like spikes at full deviation on the waterfall display and sounded like a science fiction ray gun. One time I heard a station come on and remark he saw the same thing and he was 1000 miles distant. I figured what I saw was either a space laser or a new secret radar, but who knows?

Over the horizon radar.

You should look into a yagy so you can triangulate the source.

This looks (and sounds) like local interference. Like really local (neighbors). As this is on the 10m band, HAMs a few miles from you should not pick it up if it is local. You should check if other HAMs see the same. 73 and good luck!

Good introduction, thanks. One correction: the first example showing the point-up variant being fed at 1/4-wave down from the apex will have *_vertical_* polarization, not horizontal polarization.

What about Roof Radials ???????

Wat een onzin verkoop praatje

Thank you

Helpful, useful, and informative.😊

Cool thank you but CHAAANGE THE AUDIO TO MONO PLEEEASE

Thanks for the info! 73 de KD6UYK (Tim).

very useful...greetings beginners

Nice job Vince. Congrats on you score.

I'm wondering how long an application is good for. Suppose I find ten 1x2 call signs I like that are expected to be available this year. If I file now, is the application good until I get one of them or until all ten have been given to other people who beat me out in the lottery - whichever comes first? Thanks.

Thanks

Thanks, this is just what I'm looking for. 73, OH2KAJ

clear and simple. Nice video.

Clear and very helpful. Keep up the great work.

Yes, the horozontal loop is a great aerial. I had one cut for 30 meters and it was very quiet and worked great. It worked on 20 on up to 10 meters using my atu. Even if the loop is close to the ground it might surprise you. A friend of mine said it was a cloud burner but I worked a lot of nice DX with it. It worked very well receiving the AM bdcst band. I cannot explain how but stations hard to hear like KDKA in Pittsburg and KMOX in St. Louis had nice signals. I live 85 miles from the Canadian border in the NE and the 30 meter horizontal loop outdid itself more than once.

great video!

Thanks Vince helpful.

love those pod runners, hate the price. Wish I could afford one for personal use. Wish they sold maybe a smaller unit completely empty cheap that I could afford and populate what I want in it as its basically 19 inch rack mount compatible.

thx, LU9DD, 73 !

i miss more qrn added to callsign training.

Is helpful! I have it bookmarked now. Thanks.

Is helpful! Thanks.

Does causing working split make you deaf in a right ear? Im really worried…

My take away is to use 600 ohm for dipoles, is that correct? Is the main benefit of ladder vs coax the ability to run long distance from antenna to shack? How does your 80 meter loop work? How high in the air is it? Thanks for the video.

Thanks vince, helpful

I built a 20m full wave delta loop configured as #4. It is "portable" as it is made with two 7.2 meter fiberglass poles, a pvc tee, two 45 degree elbows, and some pvc tubing. It's schedule 40. I have it mounted on 10 foot piece of chain link fence top rail. I have a home made 4:1 at the feed point. It is resonant on 20m, and I can tune it from 40-10. Works best on 20-up. I am very happy with it, it works great on 20m.

Thanks for the help. I have an FT-710. When I click COM5, which shows as the Enhanced COM port in the Device Manager, I get an error message: Access to the port COM5 is denied. Make sure you not attempting to share the port with any other function such as sending CW." Now what do I do? TIA for your help.

Thank You ! I found this very informative

Quite clear and helped improved my understanding a bit more. Thanks for putting in the time to do this. Mike .

Thank you...73 DE OK1ALZ

Vince, I want to try my first Delta Loop. My thought is for 13 Colonies Special event coming up. I have 450 and 300 ohm window line. I also have three 23 foot poles to use for raising antenna up. I have 10 watt QRP and tuner if needed. Going for CW too. Would you recommend a best Delta Loop for me in Maryland for 13 Colonies Special Event. Thanks N3EIE.
