Hi Pierre,
I've got two of these (both the 40 channel version), one working perfectly and in really nice condition, the other one a bit beat up but complete, not working (lights up and makes a hiss but no tx or rx) for parts or repair. Also have schematics on paper.
Make an offer, don't want a lot. Say $100 for the working one or $150 for both. Local pickup with cash only (Kalgoorlie, WA), not gonna post or use payid etc, too many scammers.
Loz!
