There's this thing called volcanic lightening. It happens in the ash clouds. It adds thunder and lightning to the fire and brimstone.

It's not a choke balun. It's added antenna system losses to improve SWR. Bal bal chicka bal bal.

You never quit hearing about the center conductor and the outer conductor add up to three conductors. The inner conductor, the outer side of the outer conductor and the inner side of the outer conductor. These are 3 because the inner conductor takes RF and the inner side of the outer conductor carries RF and the outer side of the outer conductor carries the common mode current. However no one says where the differential currents flow. Many telehamgelists say that there is such a thing as the differential currents. But no one says where those currents flow. They must flow in the inside of the inner conductor.

So you show the ARRL depiction of the Common Mode Current flowing back on the outside of the coax. How can you measure that separately from the forward I2? When I measure forward and reflected currents, I can actually measure forward and reflected currents because they are real. You say that an off-center dipole has different impedances on the different sides, son. Explain that within the confines of R+jX. One antenna has one impedance. You haven't learned R+jX yet. That's one R. That's one jX. jX consists of one XL and one Xc. You need a counter-Poise (against older women's panty shield) on your antenna because that's a part of your antenna. The fact that you are enamored with women's panty shields distracts from the fact that the whole thing is an antenna. Stop thinking of it as a counter-Poise. NAZ had a PhD on explaining his J-Pole. NAZ questioned the way that the antenna was connected because Dr. Ed had hooked it up "backwards" Dr. Ed correctly replied, "Oh, it doesn't matter." Why? It's because if you don't ground an output from your coax at the antenna end, it's balanced anyway. Then you can add your choke to bring up your antenna system losses and improve your SWR.

You've learned about toroids? You can't seem to tell me what the unloaded input XL is on your toroidal 49:1 transformer over the operating frequency range.

I've had a hot mic from reflected signals from the antenna but never from the sum total of the currents in the transmission line. Reflected signals are something I can measure and they're real.

How can I measure that imaginary CMC separately from the real antenna current? I can't find anyone who knows how.

If I was complaining about anything, I was complaining that your testing wasn't more thorough. If you run the mile in 2 hours, you correctly ran the mile. Could you do better? Sure you could do better. I am pushing you to do better. Fer crissakes son, you are the one who tried to show distortion on a 70cm signal with a 350MHz BW scope. ABC. Always Be Chokin' on advice to improve. Sad primate.

If the NanoVNA-H4 isn't "the best", what is? Would you add some links to the description for 'minimum gear' and 'best gear'?

Another great show filled with banter for entertainment, and enough science / facts / illustrations to make me feel guilty for not winding any of my own chokes...yet.

I used to buy commercial chokes, until I made my 1st 240-31 core and wrapped it with rg58 jumper. OMG what a world of difference it made! Much better than I could buy for $80 to $90 ! Hmmm, my ground mounted portable 20m vertical has an swr no higher than 1.2 on the edges of the band. no coils no chokes except where it comes in the house on 50ft of coax

Very good show ! Being in Broadcast working on transmitters MW/SW/FM/ ATSC TV all this stuff still applies. We use chokes. UNUN. Balun all the time. They just much bigger in some cases like a AM transmitter 50 KW . I get a lot of same questions hear and you guys gave great answers. Sometimes adds on eBay not totally correct. Balun and UNUN get confused all the time. I worked with Ziggy to correct one. This was nothing the maker did wrong. In fact is a great build and great quality. The only issue was a 9:1 Balun VS 9: UNUN . You can both with the same winding. it is how you connect them . That the only difference. Ziggy did follow up and got it right. I would have made same mistake. That's why I look things up. I was working today as well and watched re play . I am not a 9 to 5 Electrician nor is my girlfriend a 9 to 5 health care worker at a nursing home. 73

I apologize for being part of the IMD3 crowd, but I've seen one on air and I was impressed by how clean it was. It's NOT a splatter box :)

So I have a EFHW. I have a section of coax that goes to a lightning arrestor. The coax shield is grounded there. Then I go into the shack. I currently don't have a choke. Where should the choke go?

I'm surprised that the best-looking bunch of HamTubers didn't talk about Ugly baluns! 🙂

@The Smoking Ape. The first thing that you must understand is that Covid is a made up term for a bioweapon that was originally built in 2001 to identify and kill terrorist cells in the Middle East and at that time, it was called MERS. It only killed like 22 people in the Middle East. It was too weak of a bioweapon to be effective in its use against terrorist cells after its deployment in 2003-2004. Middle East respiratory syndrome-related coronavirus (MERS-CoV), the virus that causes MERS and deployed but the US Military and built by Dr.Anthony Fauci and then in 2001-2003, Dr.Anthony Fauci weaponized it with his “Gain of Function” research to make more of a contagious virus and went as far as publishing a medical journal in 2013 that with a person’s DNA sample, the newer version could be designed to kill just one man and at that time, the news was about Putin and his attack on Ukraine and the taking of Crimea. After that journal was published, that was very disturbing to the entire medical research community, our US Congress order that this research to be stopped and everything related to it to be destroyed including samples from the three U.S. universities that were involved in this bioweapon research but in 2001, Dr.Fauci had applied and was granted a U.S. patent for his bioweapons, the research and all related testing three months later. However, even with the Gain of Function research, this is still a very weak bioweapon when it comes to bioweapons in general. This one in particular could be defended out in the field by American soldiers just by taking vitamins to build up the immune system and HCQ tablets once a week until they can be transported to the rear in more reactive cases to receive the antidote. So to this day, all of us in the NBC Warfare field of training, mostly US Marine Corps and U.S. Navy has been wondering why wasn’t the antidote produced in mass since we know 110% that an antidote exists since we couldn’t deploy it in the Middle East without US Military personnel receiving the antidote like I got while working in that field in 2004. To this very day, I have not received any of the death shots and instead strived for the “herd immunity” so that my body would fight off the entire bioweapon cell and not just the broccoli looking cornels that surround the outside of the cells that clump together to form clotting. So starting in 2002, I have been donating my blood samples to be used for a new antidote through the Million Veteran Program at my VA Hospital. I came down with the worse variant, the Delta variant on July 5-12th 2020. I only used vitamins and the HCQ tablets that were provided to me by the VA, which I was suppose to take every Friday until the entire case was finished, which I kept and/or gave away to family members. Today, I take a tablet a week before getting on a plane to travel and one a week while on vacation. I still load up my pill schedulers with vitamins along with my prescription meds still today because some of our big pharmaceutical companies have been active building their own variants and I’m still waiting for a new “Election variant” to be deployed any day now, which some within our community thinks this new bird flu could be a variant but since no one in this big money field of pharmaceuticals is honest anymore, that they are willing to kill a bunch of people in order to make billions of dollars and this is why I don’t trust any form of any kind of shots now. I don’t care if it’s a new shot for the “Turkey Flu”, I will not get one. Besides, I’m at the age now that I’d rather stick to my vitamins vs all these death shots. I also feel that millions of people are taking vitamins that never took vitamins before and that people are eating and exercising better today too but we also have people that got the death shots, don’t believe that need to take vitamins and are the most dangerous people to come in contact with today…😢

No notice of the live stream this morning and I’ve been awake since 4:44am because I’m getting text messages like crazy on my birthday today. I’m watching it now and love hearing you talk about testing the G90, which I own two. I just bought the PMR 171 and I’ve yet to turn it on yet, lol. 😂

MAYBE SO MAYBE SO . What should we expect for free content 🤷‍♂️ correct host comment ….

My SDRPlay is da sheet! Money well spent and it receives everything on a 71 ft long wire 9:1 antenna.

It rains almost every day in the afternoon at Yellowstone. That’s one of the things that makes it so wonderful and green.

Howdy y'all, can't wait for some coffee and meet y'all again

Coffee,Like it, really superb vlog~)

👋🍺🍺

Great show, fellas. #TeamReplay

Just sub'd to the Ziggster.👍

The laughs on this cast are better than any slick silicone wire thanks guys 😂 always great

“Shall be no smaller than 14ga” 👀 I guess my 22ga stealth wire is out of spec…

Jim needs a new lawn mower guy; or require him to mow when he's sober!

If I were building a Power Cart, and wanted to install an insulated power buss, how well would a pair of 1/2 copper pipes do for the buss assuming that it will be installed in a manner that nothing other than the connections will be able to come into contact with it? For Rat deterrent, go to your favorite hunting/outdoors man store and find the fox urine lure, every week or so use an eyedropper and drop several drops around the engine bay.

Question for Ziggy. You used a hook that you mentioned you used for wrapping toroids. I use heavier wire and struggle getting it tight. It looks like you have a system for doing that. Would love to see a video on how you use your setup to wire tolroids tight.

Flex seal is horrible on anything that moves. It's super fragile.

I like how this turned into a stealth cat video

There's a reason fuses (break on over current) are super common and crowbar circuits aren't. Current burns down buildings. Voltage just fries sensitive hardware.

Lightening is a honey badger. It DGaF as long as there's metal nearby.

Hi guys you look good, Nick w7nik :)

For a 6ah battery connected to a qmx should i use 14awg? Or will the 18awg work?

Great show with Ziggy again ! AWG is American Wire Gauge. Some great wire on the show. I use the DX commander DX 50 wire for good dipoles, has Kevlar core. does not stretch much at all if any. I made my one power cord for IC 7300. you can buy that 4 pin plug. I made with all 10 AWG OFC wire. I did the parralo splice near plug like the icom one. but all 10 wire. then close to that plug ,I tool a FT 240-31 ferrite core . 31 mix and wrapp 10 turns threw it. that a common mode choke. then a short run into 2- 10 AWG fuse holders. They came in red so I put place heat shrink on one. Then the 45 AMP power poles. I get less voltage drop on the display then the icom cable . At my radio station we had a direct strike from lightning. at one of the 4 towers, Blue out the second down tower light. had to notify FAA on that. The end of the feed line where it cupples to tower blew a burned hole an end of copper feedline. That soloed copper. and Nitrogen filled line. The transmitter had no damage . but station off the air due to feed line. had to switch to back up transmitter and feed line . Lots of paperwork . FCC and FAA. and this during winter Blizzard in NY. 4 ft of snow ,60 Mph winds. All bets are off with Lightning . and all Lightning not the same. different power levels and can change polarly. NOAA taught me about positive lightning. 73

👋🍺🍺🍺🍺Let’s talk about some wore😂

The ham radio solutions USB paddle interface (for v-band) presents as a keyboard where paddle operations show up as left and right ctrl keys. You could plug in a foot pedal (1/4" mono to 3.5mm stereo, leave ring disconnected) if you can map ctrl to PTT.

12AWG is 4 mm2

Mason jar - more hammy hambones folklore came from CBer urban myth. Grounding safety seldom saves a direct strike . Lightning be bad ass !! It jumps miles across the sky. It surely will evil knevil across a static discharge unit. Just unplug and disconnect everything. Including computers. Throw the coax outside. ARRL or similar insurance works once.

Thanks again for the drawing last week ! Was great to win.

Great show, even though alot of it went over my head. Lol

One benefit of not drinking is when I buy something I shouldn't it's good ;P

Something I'd like in a breakout like that is optoisolaters for the digital signal lines.

Yeah, you all watch Soul Train just like you have African American friends. I call b.s. You may have been racially curious.

Great show. Tom is Awesome ! I got Email from him about that new board. I have the IC 7300 and use Headset and foot pedal. I do it from mic jack with adapter from heil sound. all the stuff is heil . Bob Heil would love that board Tom made. I love that Crowbar board that Tom has. It is cheaper than anything I can make. I fix power supply stuff very often. Some do not have Crowbar protection. and Tom sells the bare board. A customer wanted me to add that circuit after a repair of a supply. So I just got the bare board and just 2 wires and done. The supply had a fuse , so that blows. I tested that. Nice SCR tom has. I got something like that 1100 amps at 1600 volts. and a bigger one . 2200 amps 1600V . I took a bank of 450V large can caps . into SCR threw a coil back to cap. charge up caps , put washer on coil and trigger SRC , Made a strong EMP that sent washer 100 ft up into the air. I got idea from youtube video. My old PC XT still works. 5 1/4 floppy and full Height Mini scribe MFM HDD that is only 5 MB . I got 10 and 20 MB ones. only a few still work. 73
