Hey Esteban,
Interesting to see the leads of batteries with the conections inverted and the transistor in the middle.. Doesn't it remind you of something?
By the way, part of my team is leaving right now to one of those locations I told you about, for a preliminary scanning. I couldn't go as I'm busy this weekend, but I'll be in radio contact with them. How would a 'bingo!' sound like in your email?
Cross your fingers...
