They should phase out CHU and replace it with WWV.

WERY WELL! I WAS MAKE IN SAME MANNER IN PAST. RESPECT TO AUTHORS!

Количество подписчиков это количество радиолюбителей в высоких частотах. Не короткие волны. Высокое частоты это сложно, и там мало людей.

Very cool, only active up to 23cm for the time being, but looking to at least get a transvertor for 13cm this summer !! Thanks for sharing the video........73

When I was a kid in MI back in the 1960's I would listen to CHU for hours on my shortwave. I was a country kid living between a corn field and a wheat field with a pig pen across the road from the driveway. CHU (and all of SW) was a reminder that there was a whole different world out there somewhere beyond those fields and that pig pen, a world with technology, transistors, paved roads, remote controls, air conditioning, and magic. BTW, CHU sounds almost exactly as I remember it from 60 years ago, (I'm certain they haven't changed the English voice recording,) although I think they added the French announcement. When you're in your mid 70's some things fade.

Я работал на 1296мгц и там бывают прохождения. И я удивился когда принял сигнал маяка 189км, когда нет никакой прямой видимости. Все говорили что связи не будет, а она была.

Nice, 73's from France 14USDX

your videos are excellent . Very informative

Bravo, serait-il possible de faire des contacts transatlantique ou quelque chose comme ça ? 73's

Super aventure! Lâche pas! 73!

Bravo! 73, VA2NW

How to make a frequency mixer? For qo100 upconverter Good luck for your project

I had one that got +6dbm output but 4 that were much less. I think its the losses in the pipe cap filters. Still its a good transverter board for the price.

I made 5 of these W1GHZ 10ghz transverter boards and none of them output the specified output power. I think from memory the best one had about +6dbm and the others less.. I see from your video that yours didn't achieve 10 mw either. I really like your video style. Clear and informative.

Gr8 job! Looks that microwaves are the area that some DIY is mandatory. HF, VHF, UHF is available now by quite cheap TRXes so there is no impuls to build DIY staff... But even DIY TRX for HF and then do QSO by that - give me more pleasure than use ready to use device. Just started play with microwaves too this year and it's a lot of experiments and learning on front of me. I think the worst is avability or/and price of measurement devices for such high frequencies. Greetings from Poland /SP6JAP/

Where can one find a calculator to figure the distance the feed horn sits on dish for different frequencies?

Interesting subject. Last time I get Kuhne 10GHz transverter but up to now I had no chance to do any QSO... Not so many crazy people are around. Here in Europe I have access to QO 100 satellite (2.4Ghz uplink, 10GHz downlink) so I decided to build upconverter by myself starting microwave journey.. very interesting. I think we need more satellites to make microwave activities more popular.

nice project. I hope continuation of original projects will come.

cool

спасибо

спасибо, хорошая работа.

Very helpful and deeply decribed, as usual. Thanks Bertrand , it will help me to build mine.

спасибо хорошая работа

спасибо, хорошая работа.

Really amazing, thanks for sharing 😊😊

C'est manifique! Beaucoup de choses réunies en une seule entité. Ce gain sur l'antenne parabolique m'a fait rire comme un enfant devant votre réussite !

спасибо, хорошая работа.

спасибо, хорошая работа.

Awesome series , I'm as new to this as anyone can be and still trying to understand not just know and the details you focused on definitely helped. Oh and the use of scrap is just the way to go :) merci

Really cool system 😊😊

I catch it in Alsace (Central Europe) by night on 7850 KHz

Really cool project 😊😊

Very cool 😊😊

A really, really big thanks for taking the time and trouble to upload this series of excellent videos. 73 de Steve M0KOV

awesome! what coupling cap did you use at the input exactly? also why no coupling cap on the output? it is DC coupled and can influence the bias of the second stage. and how did you measure the input VSWR? thanks

спасибо, хорошая работа.

awesome

хорошая работ

The BW of the loop filter and also combination of integer and fractional ratios also have a big impact on phase noise. you may want to look into those as well

all chinese made synthesizer boards use the same regulator for AVdd and DVdd just by adding a simple filter. Consequently the layout is also poor and couples the digital to analog path. even some of their cheap bench top signal gens use the same design which is very wrong. DVdd and AVdd must use separate regulators and the layout for DGND and AGND (even though they are electrically connected) must be carefully separated to minimize coupling. of course all of that adds to the cost. AVdd also needs a lot better filtering of course.

Et les sous-titres ?!! 😅😂😂😂 Force à toi continue comme ça ✊

I was playing around for the first time on an emergency radio that i guess can listen to these stations. I found this station, I'm in the USA

I have this 10GHz transverter. Only just got around to building it in the last couple of weeks.

Would a MAX2870 doubled be better? It has a much better Jitter rating than the 4351

Jamais vu ce type de feeder, intéressant et original!

Aurait-il été envisageable d'installer un dispositif d'accord rondelle/boulon à l’arrière du guide d'onde pour obtenir un réglage plus pratique ? 73's de FO4MM tahiti

Excellent, G1ORP

Tu vas utiliser un twta avec ca ? hâte de voir cette série !
