1.) Es wäre schön, wenn Ihr mit den Forum-Teilnehmern so umgehen würdet und sie so ansprechen würdet, als wenn sie Euch gegenüber sitzen würden.
2.) Es gibt für niemanden einen Anspruch auf die "Lieferung" einer RF-Platine, weder jetzt noch zu einem wie auch immer angekündigten Zeitpunkt. Wir sprechen hier über unser Hobby :-).
Ich bitte weiterhin um mehr Gelassenheit, Höflichkeit und Geduld.
Viel Spaß beim Basteln und bitte nicht den Ham Spirit vergessen,
Frank DD4WH

...und ganz Ungeduldige, die außerdem nicht selbst bauen können oder "wollen",
finden hier preiswerte Geräte, deren angegebene Wartezeit sie u.U gerade noch in Kauf nehmen können ;-))

PTT ....
HAM SPIRIT is a mater of choice for each individual. I still and will believe in it and I behave accordingly.
Big companies need a lot of time to develop great things. Do you still remember the time ICOM needed for the IC-7610 to come out? To refresh your memory: 2 years after the initial announcement.
So if we have an individual like DF8OE willing to do something for all of us, who we are to blame a single person for "non-delivery" versus big companies? For me just a new OVI40 UI board is already a great progress, with enormous future potentials, complementing the existing mcHF RF boards.
Try to enjoy the hobby, it is a very beautiful one, we don't need to argue each other!
Respectfully to all forum members.

Hi
I probably should not be speaking here, I'm from another country.
Josef, you are right where there is money, there is no hobby and vice versa.
I would like you to know that.
I know a fellow who bought the controller because they wanted to have New Tansceiver in 2019
That was what the seller promised them.
"2018 ist definitiv sicher."
Now they have no radio, this is Ham Spiryt? WOW!!!
Sorry money should impose obligations on the seller!
Josef are great that you had courage, I wish you a lot of health.
You are not alone - there are many of us.

Goodmorning everyone.
When we all worked together to improve the mchf, we started from the basic scheme and each of us gave his small contribution, theoretical or experimental, to make it an excellent trx.
Now that the development of the RF board is secret, how can we contribute to its development?
It is no longer an open project, we do not have a common theoretical and experimental development of the RF board.
In my humble opinion, in doing so, many human resources that would certainly have helped the development of the project have remained unused

Hi Paolo
It's nice to see you. I'm just finishing the TRX project at 23cm
I do not have a general scheme, but I have a block diagram. How do you like it?
There is an two intermediate frequency of 6.5MHz (one IF is 32,5MHz), so you can do balance mixer on the whole bandwidth, there are SAW filters. Maybe Andreas will be able to copy something, maybe he will be the first, I will be very happy if he does?
Filters SAW at 23cm made for me a factory in Korea (no Northern  )

I made a lot of PCBs in different variants until I chose the one best (all green PCB is TRX LAPWING):

Bless you!
