I think radio rallys are brilliant because I went to the Blackpool Rally last year and I brought a Motorola GM-350 ex PMR radio 4 channels and it pushes out 25 Watts which is decent and in my area I speak to people all the time on the 4 meters and I also got a Kenwood desk microphone for my Yaesu FT-950 for £54 and the radio cost me £35 but I was very happy with what I got at the rally and there was loads of hams selling junk in the bag like what you got for £1 there was loads of stalls like that up in Blackpool. Thanks and best 73's for now cheers. Stephen M3SNV 73's.

I've built this. Can hear my signal at night coming back on SDR receivers. Always detectable in Netherlands at night and heard as far as Northern Ireland. Tx based in SE England. Also tested the Corsair around 9 watts and S9 in Northern Ireland and S3 in Iceland using a half wave end fed washing line aerial. QRP on 6MHz works very well at night.

Just came across this video after finding out my wireless charger does a similar thing as well. I got a charging dock for my phone and watch in order to tidy up the mess of wires. Then I noticed some very similar interference on 2m, but also on 20m! Mine is more of an S9 pulsing at regular intervals on 2m FM. And sounds like boop.... boop boop.... boop.... boop boop on 20m SSB Initially I thought I solved it by wrapping the power cord in a ferrite but it came back. I guess it's likely from the induction coils and it's probably doing some sort of sweep to try and detect if something is sitting on the charger. I'm not sure if there's much that can be done about it if it's coming from the coils, other than try and find another charger that might not do it as much. My solution for now is just to unplug it when it's not in use.

Wiring off brand speaker-mics to work on other brand HT's is a pain in the neck. I wouldn't recommend it.

It works with Baofeng UV-5RTP too.

I have the exact same problem with a Yootech wireless charger. I also have the official magnetic Apple charger that does not cause any RFI. I am looking for a replacement but hoping to save a little by avoiding the official Apple charger that reminds me of a stethoscope. If you find a brand on Amazon that is RFI safe, please let me know

Good fun and you did pretty well in compromised circumstances. A short whip, 1ft off the ground with trees blocking signal either side...that's quite a test and you got some good results. Would love to have seen how you would have done with a clear take-off. I've subscribed.

Tried one Eachine TX 526 but that just knocks out the RX monitor.

Somebody gave me one. Hardly anybody has one.

Had any QSO's? ...hit up a local ham on QRZ and give it a crack! If I was nearby would gladly be in on it....I love self discovery learning. The more mad scientist ...the better!!!! 73 VK2AOE

Down where RO's used to live! Love it!

What's the fan for? Cooling the highly efficient 1W amp. Utter PANTS!

Thanks for this. I have something similar that I'm trying to identify which is two to three pulses, then a burst - this is helpful.

Operating these kinds of devices are a good exercise. They are no doubt a compromise antenna. But operators learn new techniques to make them work better and better. Nice to see these still around but used only. They still fetch a premium price when they show up on eBay. Fun to watch your video. 73’s de n5vwn

Take a ruler, measure everything, count the turns,the diameter of the wire. And publish a sketch of the antenna. You will be thanked by Everyone. If it costs little , it means that it is easy to manufacture.Why buy if you can repeat it ?

I have a couple of the VC-H1 units I used with my students when I had a school club back in the last 1990's. I had the VC-1S software and I can't seem to find it. You you have a copy of the program or what did you use in your video. Thank you. KC7HEX

hi.....how many windings has this isotron 20?

Great video.. I have one and mine says made in Japan.. I do have a Vertex/ Yaesu VX 150 that says it's made in China..

nice review would you know where I can find the antenna in the US Thanks Mike

If any of you just bought the FT4X you will notice a part that came ln the box that is not on the packing contents. It's black with a flat base and two metal tip pins. It took some time and web search but I found out it's for foreign power supply adapter. Should not even been shipped with a usa sold radio.

Many many thanks for posting this, it really helped me as I had the same problem! The wireless desk charger is branded "Yootech" from Amazon, my pulse was about 4 per second so a bit more rapid than yours, radio is FT991A and indeed the whole of 2m was ruined. I live detached so knew it had to be me, was worried it would be the central heating controls, which can't just be turned off! Thanks again Adrian G1TTX

There's an error in your schematic. There's no B+ supplied to the collector of Q2 Q2's collector as indicated in schematic is connected to the output of the LM386 through L2 and L3 but there's no connection to the 12V power source. This wont work - please post revised schematic

THANKS!

Isotrons (Bilal) are typically 2 S-units down on a wire dipole. Worth £10 though to find out the truth for yourself!

It's a Baofeng with a Yaesu badge. Nothing wrong with Baofeng's, I have 5 of them and a Yaesu FT3DR. But just know, you're buying an over-priced Baofeng with slightly better build quality.

I'd like to know about your antenna coil, and how you measure swr....

@MakingRadioWaves would you be able to send me a picture of the inside of your miracle whip while the dial is pointing at VHF? The knob fell of my antenna and since it is not a set knob, idk where to set it to make it point properly again. PM me and I can send you my email address. Help would be appreciated

Should the Tone be T and not R?

Why not using a pad for FT8 ? Just vox ok

Is it possible display always on

is it possible to programme the radio to transmit on PMR446 channels?

Just try programming one. I used chirp and the SCU35 cable. All the channels appear to go in but press transmit and Hey presto! ERROR!!!!!! My Baofengs are easier to use. The receiver is good but it's not much use. It stays at home and I use the Baofengs to talk to other hams

Diagram?

Is there anything NEW today that I can get like this?

This is a fantastic piece of equipment by Kenwood. Mine is still going strong. I am hoping that one of the major players such as Icom or Yaesu comes up with a stand-alone SSTV device if Kenwood does not. I know that you can send out SSTV using a PC or Android now, but a dedicated device would be amazing for all HT users interested in mobile SSTV. Thanks for the video! 73 de KC9MAQ

That isotron looks interesting. My M6 brain can't really work out how it or why it works??

That isotron looks like an interesting find. Keep us in the loop please on your insights. And, could not agree more on going to a the ham rallyes. I found my most treasured posessions at the most unappealing swapmeets. 73 DK3LJ

These look nice

That is not a lot of drift. I am building a station for the new Es'hail OSCAR 100 sattellite which ha a 10GHz down link, so in addition I consider setting up for general terrestrial 10GHz reception with a TV PLL LNB with a stabilized reference frequency. How far was GB3CCX from your location ?

Nice Video And Hello From Shakopee,Minnesota,USA

Nice one.

Strong signals

That drift! lol

I was thinking of getting one of these thanks for the video.

Nice video! Thanks for sharing

Thanks for the video.

A storm chaser buddy of mine runs one of these. He likes it so I started looking into it. Little high price wise for what I would like to do but I'm thinking about getting one for my XJ (next year sometime perhaps). In the meanwhile, I think I'm gonna order the $98 kit w?GPS and case and use a spare 25W Maxtrac I have laying around in my DD.
