I’m surprised there seems to be no recent posts from Alex VK2PRC. Nonetheless, I can assure other Hams, these couplers as spec by Alex have worked specularly well for me, especially on Australian coast using just 20W. If I deploy the ICOM7300, results have been in the stellar class. And I’ve learned a bit along the way. Thanks VK2PRC from VK4ACF Rod

THANKS FOR SO DETAIL THIS PROJECT! "73"

Alexander, I am looking for a part for my PRC-320. It is the 1mm x 6mm roll pin that holds the thumb nut on the antenna post. Would you happen to know the NSN for the roll pin, or where to find this item? Thanks in advance!

This is an awesome built . Especially the coax as capacitor . Just like the gamma match on yagi . Love it . Saving this for future build .

I tried to inquire by email but it failed to deliver: Your email? I’m interested in your 20-40 match box.

Thanks for this easy to build DX antenna AleX ,and say hello to ELON MUSK from me 🥴

Great explanation Alex. Very methodical very logical and easy to follow. Well done. Most enjoyable to watch. Richard. VK2VD.

Good job.

Why do you use a 3 kΩ terminator for a transformer with an ipedance of 30:1 (5.5^2)? I would expect it to be 1.5 kΩ.

Hi Alex superb well explained fault finding i have found the exact same problem using your diagnosis ,clicking relay when apply battery and it appeared shorted solid state transistor with voltage on its output when set was turned off. many thanks for your time posting these videos invaluable advice. Turns out it was the pa relay shorted causing a back feed to the solid state transistor switch .just need to check the solid state is switching as this could be the cause of the damaged pa relay.

Great. Lots of detail. So many others assume you know some stuff, which I don't know. Bravo.

Hi, where can i download a copy of the schematic Mike Mw7eyc

can you not scan the pinouts?,the vid is not good to copy the document from.

Super work!!! New subscriber

Hi! I'm just now finding this video after looking for something similar for years! I'd been looking specifically for something called a Clandroid kit (a fusion of a clansman radio and android smartphone), and am also curious if you had ever heard of it. Thanks for the informative video!

This is the only antenna I use. Bloody terrific performance I must say.

What toroid, how many, how many wraps, and what coaxial cable do you recommend for the RF choke on this coupler? Or would you use a Reisert Method and one toroid? Using your video I made a coupler.

Absolutely love the Clansman!

@vk2prc978 Do you have an alternate source for the VFO kit? The website appears defunct? Thanks Ed M7TXA

Your math should be Power = 10 * (Vp)^2 in Volts and mW.. Your meter shows peak voltage Vp (not the rms voltage).. You may add the 0.64V drop to the Vp to be more precise..

Thanks for the info as it may help me with figuring out the issues with my PCRC-320. I tried to do the LSB mode and it hasn't bee the same since.

Hi Alex in the new box with the yellow toroid is it just the 20m antenna using the toroid and the 40 meter not. It seems the 40-meter configuration does not use the toroid but just runs around the box to the connection back to the radio. I hope that makes sense thank you, Ethan.

Alpha1 ?…great pirate call !

Thanks, good job.

Would have been nice to see inside it can only be a simple indicator and capacitor or ferrite unun which i dont think it is as it would give you 10m as a harmonic so guessing its a enamelled copper inductor and a bit of coax as a low value capacitor. have you thought about useing the same coax connection and just running a bypass wire to the 40m terminal saves an extra so239 that way its more economical to build and quicker to change band and works the same

Only just getting into Ham Radio, and have decided to go for the 320....spent my life in engineering, but I'm not much of an electrics/electronics guy, but very interesting......

While your channel is an invaluable resource to us Clansman fanatics have you considered writing down everything you know for posterity? Ad the preeminent source for service and upgrade information you have been far more effective than any number of original manuals or forums in keeping many radios alive.

That’s impressive :)

Use to fix these in the MoD

Unless its changed since my time you need to drain both tanks first. We tasked a guy with doing it and 3 hours later no empty tank, he took fuel from the right and put it in the left, self leveling system.

Awesome!

Good job.

Good job, a true 320 detective !

ave you any details for converting the slim cougar eletret speaker mic?

so what caused the transfo to short alex?.

Look lot like mfj 16010 atu ??

… longest dx ever 😂😂

Impressive Test Jig! Enjoyed the video!

You mention the coax capacitor, could you upload a video regarding that item? Would love to learn about that and how it works with your project in this video. Thanks! 🙂 De VO1MDS

hi, nice video and circuit. I did try to make a auto switch, but i was lucky to have the amp switch on my ts 480hx, which simply connects the power across the relay, the switching line has no power on it from the rig, so no sensing circuit required, its just simply a switch .it seems to work ok, although i am not sure, if i should have other components onboard for protection. sent you the circuit via email, if you could comment on it, would be very much appreciated. cheers. brian zl3xdj.

Wowww❤

Hello, what is the cost of your end fed coupler with postage to UK. thanks.

Going to try this test on my own radio see if I get similar results. Thanks for the info great work both.

Hi Alex, what does the SURF unit mean? VE6KBI Dana

Great video Alex. Thanks for the link and great to chat to you on the PRC320. Cheers Ian. ZL1HIM

Wow 😮 that was epic!

Hello Alexander, quick question, How many turns would be necessary to obtain good results on a T130-2 toroid?, 18 awg enameled wire will be ok?. It’s for use with 50 watts maximum. Thank you!!! 73

Alex have you ever measured the capacitance of the matching stub?

Thanks, much appreciated! Greetings from Norway :-)

Did you ever experiment enough to find out the effect of different value capacitors on the timing?
