Finally found time to finish my little integrated (tr)uSDX TRX. It has the same built-in speaker, but I included a PWR pushbutton toggle switch which turns on the radio, lights up a 3mm LED and charges the built-in AF amplified speaker internal battery, thus eliminating the need for the micro USB connector on the Lower Panel: one less thing.
When the radio is ON, the (tr)uSDX 5V rail powers the amplified speaker. The PWR pushbutton toggles a small FET latching switch which then passes 12V from the 5521 barrel jack just below the PA control jack. the Retevis speaker/mic combo works fine and when the dual 3.5mm plug is inserted, it disconnects audio feeding the built in speaker, of course. Sounds pretty decent IMHO. Check it out here: https://drive.google.com/file/d/13GbJIj ... sp=sharing
This particular TRX has the Classic Bands board and works very well indeed. Thank you again Manuel and Guido!
NOTE: Although "DL2MAN/PE1NNZ" is not emblazoned on the faceplate, "(tr)uSDX by DL2MAN/PE1NNZ" is debossed on the top panel.
I have a "high bands" RF board and another main board - I may build a second TRX just to get 12m and 17m. We'll see...

Re: (tr)uSDX Updated Built-in Speaker
Congratulations friend for the designer, was it printed in 3d? would the project be free or commercial?

Re: (tr)uSDX Updated Built-in Speaker
The case is 3D printed and the front panel is a black PCB with white silkscreen lettering. There is a bit of circuitry on the underside of the PCB for the LED, power supply and power switch and AF attenuation. I'm not selling anything - I did this for myself.
