Thank you very much! Radio Amateur Andrey-RK3FC sent the circuit diagrams!
Here I've posted a video detailing the assembly of this transceiver. With my modifications, for my enclosure. It's a primer for me. This is for anyone who wants to replicate this transceiver; it's very easy to operate and can be built from your own components. Some parameters may be degraded, which aren't that important to some. The most important thing, after all, is the antennas. I've noticed that some correspondents operating at high output power can't hear the radio amateurs responding to them. Meanwhile, other radio amateurs from the same area can hear them. This is, to some extent, for those who have similar or identical enclosures and want to build a transceiver like the one I'm making. Good luck, everyone!
