So what does it take to get one pre built like this?

Love to hear that Morse Code is still the most effective way to DX.

Solid State?

Congratulations very good job... this Amp working good on 11m Band...?

Nice !!

its work good on 11m..?

Ωραίες κατασκευές αρίστη ποιότητα και το σπουδαιότερο κάνει αυτά που υπόσχεται και επίσης πολύ καλή τεχνική υποστήριξη από τον Δημήτρη σε ότι χρειάστηκα . Ποτέ δεν κατάλαβα γιατί όταν έχουμε Ελληνικής κατασκευής, τέτοιας ποιότητας μηχανήματα, ψαχνόμαστε να αγοράσουμε από το εξωτερικό και την ίδια στιγμή οι ξένοι ραδιοερασιτέχνες αγοράζουν από Ελλάδα. Αλλά θα μου πεις Δημήτρη ουδείς προφήτης εις στον τόπο του. Θανάσης SV1SVO

I can afford one, but the import duty and shipping charges/fear of damages are there. De vu3mes

Can you please make a video about how to use boards to connect with radio, antenna and power supply? That would helpful for home brewing beginners.

Yes please.

How can we buy it?

Wat is the link of the producer

I heard IW1DAL from a friend today, but are you sure that when you changed bands and went to TX with 1000/1200w there was no one on the frequency? Imagine if everyone did this -I understand that to show that he goes on all bands without problems with almost instantaneous agreement you could only do this.but it is not a practice to be implemented. I am not and do not want to be a policeman , ma se 100 rookies vedono il video e poi fanno dei test uguali a questo chi gli spiega che e' sbagliato? Hai xxx visualizzazioni , CZcams e' un arma potente 158 / 5.000 but if 100 rookies see the video and then do tests similar to this one, who will explain to them that it's wrong? You have 972 views, CZcams is a powerful weapon. Best 73, s from IX1HPN

Hi! Are you still in business? And do you still have the automatic band change modification/board addition available? If so, what is the price and availability? Thanks. I have two of your amps, bought second hand from KL4QG (KA2ZSD/KL7). KE3Q

Wow long transmitter

I love how the power returns to zero quickly. I noticed after the firmware update it is like with the normal lcd. Very slowly going back to zero... is that because of harmonic buildup in the filter?

If I was to build a mono band amplifier for just 160 meters, would it be advantageous to use this board over your mrf300 board? Thank you for the video.

Do you have a version that covers 75 and 60 meters?

Super!!!YO9AKM/73!!!

If I understood correctly, you have to open both voltages, 50v and 12v to adjust the bias with an ammeter on 50v?

Looking forward to test it ON6PL

Any links to the proper sized aluminum heat sink for this specific application that I can then purchase?

When you bild one for me....😂 S51TK.....

OK, box it up and ship one to me!

Dream machine!

wich range of impedance mismatch accept?

Congrats Chris! Well done! Actually, the best you can get for your money. Basic, robust Amp with good specs and no unnecessary blingbling. And in case of any issues, easy to repair without sending the Amp around the world and without receiving another bill at the end, amounting to half the price of a new device....

how about 70 mhz ? it seems linear up to 50 ........ the gain will be less on 70 mhz ....... i wonder what happens , the IC7300 will do 4m as well ............

Ευχαριστώ 😉 73

freue mich auf die Lieferung....vielen Dank an das DX World Team.... man hört sich....73 de DF3DZ, Dieter Dortmund

Hi, can you tell us what has changed on the V2.0 ? TU 73

Hello, What is the difference with the v1.0 version ? 73

👌👍

Hello, will Ft8 get the same TX power as the RTTY you used for the test? How about the power voltage? 53 V? Thank you.

πολύ καλή δουλειά

Love the 7" display Demetrius. I building the 1.2kW boards with MRF1XK80H you sent me. So far its going very well. I have completed the machining of copper heat spreader and I soldered the LDMOS to the copper. Next step is to bench test the amplifier only and connect up 12V DC Bias and the 57Vdc power. Just to give a quick test with very low drive. (~4 to 5 Watts) Just a test for 15s. into a 1kW dummy load. Then finish the complete build of amp with the LPF Board and the Protection Board. I have many friends interested in this build. If it goes well I might build one rmore. Dan in San Diego W6DKW

I like how it changes band automatically.

Great Great job!!!

Can it work for 160m FT8 to get 800W？

Very nice and like the tall cabinet for better air flow!! Unlike the Mercury which is in a very tight enclosure especially with LDMOS cooling. Great job!

how is the LBF automatically switched depending on the frequency?

thats one nice amp

show the entire setup. please provide a connection diagram

Gefällt mir ......ist das nun die Endstufe für mich ? 73 de DF3DZ, Dieter, Dortmund

Dove ordinarlo???

Did you try 65V to get 1800W？Which power supply in the market can do 65V 35A？

What is the price? and.... Antena switch is auto by band? Thank's

I am interested in this kit. Can it keep kilowatt output on 160m with your 5th order LPF? Would you show me the test before I place the order ? Thank you.

Do your smps work on 60m and 30m also? how about 11m ?

Beautiful.
