Otron CB-402

[Van Lifeson]

Just picked up one of these brand new in the box and can’t find any information anywhere on the Internet. Anybody have any idea how to boost the audio on this thing with a diode clip? Thanks! It’s pretty anemic audio wise.
Also need mic wiring. It’s not cobra that’s for sure.

Found a pic of the schematic from the owner's manual here: https://www.marktplaats.nl/a/teleco...cb-402-40-kanalen-mic-houder-handleiding.html

The mike wiring is shown in the lower right hand corner, but you're going to have to work at it. Not a high quality pic by any stretch of the imagination, but then there's not a whole lot out there on that radio.

you ain’t kidding there’s not A whole lot out there on this radio. Lol. I will say this it has fantastic receive, nice, mellow and clear sounding. I just got to get the transmit audio sounding a little better.
