Happy Holidays to you and yours

RTL v4 have upconverters built in how wide spectrum can you monitor at once

I have 4 of these. One does 3w on hi, two of them do3.5, and one does 6w. whatever

Hello, Have you tried using two 240-43 cores for a 9:1 unun looking to put a little more power to it. Any advice would be greatly appreciate 73s

We also tested it with the Tiny first but it is far from the real parameters, then we tested it with a Ricon Ozilograph and that device has better values ​​than the President Washington 2, we had the Any Tone AT6666 Pro which is the same as the device tested in the video! Conclusion: if you want something good and for a fair price, I can only recommend the AT 6666 Pro!

You recommend version 3 or 4

Dipole antenna?

Thank you! Very creative! Should the left side Mode/ Status LED above the LCD light up red while changing and then green when charging complete? Reason I'm asking because I just got this brand new FT70DR and using just the SAD-25 a/c adapter that came with it to charge but no red LED is lit during charging. According to the manual the Mode/Status red LED should come on...

I like those batteries, i use them in my trail cameras and my FoxPro. I have used them for years before replacing them. I now use the black Tennergy (2800 mAh) and have no complaints

Bro I’m still so stuck between this meter and the Nissei HF/VHF/UHF digital meter I literally cannot check one out

I'd offer to do diagrams for you but you do a fine job yourself. Don't let anyone cast shade on your diagram skills.

Any digital connectors on anyone these for APRS or digital Vara fm?

I have this antenna and absolutely love it. Use with my FT-710 and my G 90 and fits in my Togo bag very nicely. Would absolutely recommend this antenna. W8BLT

Is the vertical portion the hot wire, and the radials are the negative?

NIce content sir, can you recommend me which Nagoya model should i get for my BaoFeng BF-F8+

SWR✅ How about antenna feed point resistance?

Baught the Kit prebuildt from Banggood, and the switches and chassis from Aliexpress .......: finally got it to work, after moving just the cables for the input, and output between pcb, and so-239 , Ver. 3.2 software. so what i learned is to keep those wires as short as possible from pcb to the ant.connectors! 73´s and thanks for making this video de LA6REA.

Merry Christmas Ape. KO4HPC 73 :)

I wouldn't have expected much loss. Good test anyway. QRP here, nothing over 5 Watts and less so I don't want losses. G4GHB.

Seeing the difference, couldn't you technically have a combo balun/unun by using a DPDT switch?

The coax choke balun only attenuates current on the outer shield and maintains the 50 ohm characteristic impedance of the transmission line. The bifillar wound choke depending on the wire gauge and wire separation distance may not. The bifillar wound choke is more temperamental regarding the core material due to the fact that it is working as a transformer with only differential mode currents flowing, whereas the coax choke only works on common mode currents flowing on the outside of the braid. The common mode coaxial choke is therefore inert to the transmission line and behaves as if it is not even there with only the extra length of coax used to construct it as an attenuation loss. The core material used to make one is therefore not critical in regards to differential (normal mode) of operation however the choice of a material that has a high impedance to the frequency being used is advantageous.

To really characterize real world performance, you need to look at the attenuation the 20 meter signal at the adjacent ham bands. In the case of the 20 meter filter, it is down a little over 30 dB at 18 MHz., a decent reduction, and it should be a lot better at 15 or 40 meters. I have experienced operating a 20 watt 20 meter station using a very similiar designed filter, and my 20 meter signal caused severe interference to a 17 meter station operating 200 feet away. The 17 meter station then moved to15 meters and all was well. In that instance, it may have been that the station on 17 meters could have stayed on 17 if he had been using a bandpass filter as well.

The reflector becomes more important on the lower bands, especially 80 and 160. Not just a single wire, but multiple, all parallel to the radiating element. Ground losses go up as frequency goes down and the closer the antenna to the ground (in terms of wavelength), the more RF power that gets absorbed bythe ground losses.

So I need thr dongle plus software to be able to have thr water fall

Can I ask the simple question - given this style of winding, I assume I locate the pairs that conduct and map them 1:1 to the coax I feed in/out? I've measured mine, and indeed if I measure one side, I get -35db, but both sides balance out and I go < 1 dB.

Thanks for great teaching, king of roids. 😊 Does a double bazooka need a choke, as I thought if done correctly would cancel CMC?

Thank you. Now I can stop looking for their signal on some meter and scratching my head.

Viking age asks generally did not have nearly such a long beard. A later era boat builders' axe might.

Most businesses know that news customers can be pure gold. Those businesses do things to keep those customers. I have not seen a lot of that in the ham community. Back in the day, people bought from stores and there would be knowledgeable sales people. Now people buy from Amazon. So channels like this are SUPER HELPFUL. Minimal acronyms, visual aids, slow-moving concepts. Thanks !!

Dear Mr. SmokinApe First off, thank you for sharing your knowledge. I would like to ask a couple of questions about "multi-tap" ununs. I only see a few HAMs build and use their own but never any retail options, so I wonder are there drawbacks to them. Also with say a 7 tap unun, is it likely that it could replace the need for a tuner? I have asked those other HAMs who posted theor builds of multi-taps but no reply. Thank you kndly Gary

Found one in Alibaba I think I’m gonna buy it lol

I just got a QT80, about to put it through its paces. Good to know spurious emissions aren’t a problem. It’s built like it’s ready for travel, no fan, just a massive heat sink.

I bought this meter and how do you figure out what the battery life is without plugging in the charger?

My 2 element 80m quad uses 75 ohm RG6SAT cable and it is easy good for legal limit.

Just passed my Tech and General exams, waiting on the FCC to update CORES. Thank you for this reference- I knew something like this had to be published. Thanks for showing me where to find it!

After watching this I wonder why I would want an OCFD

Good information (as usual) Thx Ape !

Doesn't Balun term comes from BALanced-UNbalanced?

Thanks for the video. I have decided after many a wasted weeks trying to get these SDR dongles to work on a raspberry pi and none of them do even if they say they do except for SDRplay. The rest is junk. Too many out of date GitHub rubbish and out of date videos. SDRplay is a winner.

Thank you so much The SmokinApe,KK6USY,Ziggy!☺️

Did you saturate them with power to determine if the work under load?

I think your comments are relevant but not entirely accurate. For instance there are several Baofeng models that receive air bands such as the BF-F8HP Pro. Also there are several Baofeng models that allow you skip frequencies or stored channels during scans. You are correct about digital and trunked; however, some communities still use analog. Even in Tucson where I live, TPD and TFD don’t use analog anymore, but there are suburbs and other community agencies that use analog. And many communities will repeat to analog. I am not suggesting you will get a lot, but I receive plenty. I would do more research and revise some comments. As far as front loading and spurious emissions, I cannot comment as an expert, but I have seen most experts say there are issues.

Well done. very nice test using regular off the shelf test gear.

I inherited a bunch of stuff from an SK. Almost none of the coax he had was 50ohm.

In my experience there's no such thing as a temporary antenna install :P
