Hello, just wondering where's a good place for transmitter/LPF schematics? Ideally I'm looking to build a 49m unit, upto 100 watts.
I'd like to do a bit of Sunday SW TX'ing 😉
Any pointers would be greatly appreciated.
Thanks!

Most of the schematics in the net are very old and not of much use. Youll be better looking at the stuff on the Class E website for ideas and the CMCD stuff from W1VD is a good place to start.
100W (carrier), you'll need 2 devices if you have 96V. I find it a bit less scary to use 4 devices and 48V. Either will give 400W pep.
Lots of great devices around, the latest GaN being the best but the SiC devices are much cheaper and good enough.
Let us know what you decide on.

Hello, could you please stop your disguised advertising for your mediocre transmitters?
You've been called to order too many times. When will you understand that your work is bad and that you have no right to advertise here?
Have you read the full CDS report on your work? How dare you continue to propose and sell such things?
Please stop.
Please stop. Thank you.

WTF!
I'm not advertising anything and no idea who you are.
My latest offering wont be advertised on here and I've gone on to design equipment that Im sure anyone would be happy with and many are.
New markets are opening up around the globe as countries are actually allowing hobby broadcasting on SW and Im currently in the process of getting a 250W design CE approved, similar to the FCC.
So there!
Please go away and stop your negative comments.
Thank you!

Stop playing games, you're a fraud. Stop taking advantage of ignorant people. You don't have and you won't get any CE approval, it's all nonsense.
You're a liar and a profiteer.
The proof is in the work and incessant comments of others here. You're a lousy hustler.
Please stop. You have no approval of any kind. Either to sell or to advertise here.

Oh dear!
The ONLY ignorant person would be yourself.
Anyway Im not going to enter into any argument with you but just to say I'm certainly no fraud.
No idea who you are and you certainly cant tell me or the 'ignorant' (rather rude!) Folk on here what to do either.

I will rot all your posts on this forum with the simple truth that you are a scammer. I would link everything that has already been said about you here.

Will give you something to do then..

Keep it simple.
There are several reports of spontaneous combustion involving your transmitters!
You have (and will have) NO approvals of any kind (FCC or CE or whatever bullshit pops into your head).
Mythomaniac !

Folks... let's keep things civil.

Indeed.
Must have been on his mind for some time and looks to be his first post.
Nothing better to do perhaps?
Just to say I'm very serious about CE certification.
Does one not realise designs change/improve (years on)?
Possibly best to vent your issues whatever they maybe elsewhere.
No worries.

6kradio's post is his first post.
I think it's simply that it's him, in order to keep visibility on the forum.
It's incessant and it's always the same; he knows better than the others (there's no point in being interested in what's on the net, it's old and rubbish, his class e is the best in the world).
He literally asked "Let us know what you decide on".
He makes fun of people and finds a way to answer even when he's wrong.
This guy is a pathological case, selling mediocre amps that burn out accompanied by stickers reminiscent of a TV series. Who's he kidding?
Bring it on all you want. You've no idea.

I request the complete deletion of the thread and a unilateral call to order to stretshitman.
