microBITX / uBITX full extra desktop radio

Hello radio friends,

I’m decided to create a desktop version microBITX radio. Why it will be a full extra version? Because there will be an orange pi PC for remote control & digi mode operations in the box. It can be used for logging, control the antenna tuner and rotator, etcetera. Winkeyer 2.3 compatible keyer will be included also & a serial connected SWR meter.
My plan is to be enough room for improvement & features implemented in the future.
So first I fount an old digital voltmeter in my garage with a super large box. I’m in rebuilding the box as a “project box”.
Nextion display worked fine on my wooden model & I loved it, so keep in this version. Extra arduino with DSP code also worked well so it will be part of this version.
My plan is to change the final ampifier to kitandparts 5w amlifier. Of course not a kit, My built from scratch. https://kitsandparts.com/5W-A1-Amp.php
First step is clean up the interior and design a new front panel.

It was only a test with power switch, and nextion display.

Near to finish. The design created with libreoffice draw on my linux PC.

Let’s put power supply in it and power on. It seems like a radio, but not it is just illusion. 😉

Radio Panels are designed with SMD devices, but full description will be published in another post.

Some arduinos are next. Radio control & SI5351 will be on top of the others. All soldered in to development boards.

So it is time to plan the internal layout.
