Hi guys
I build my one CHANCE and i got small problem, some strange signal rises even with unconnected coil, for me sounds like 50 hs power line interferences but i try in the field around 200 meters away from the "civilization" and i got still the same signals. just with barrier on level 16 gets bit better.
I think that can be something with receiver section, i used some replacement parts 2SC945 - BC182; КП505 - BS170; A733 - 2SA1015. Maybe BS170 is the problem?
This is link to my video, please have a look and give me some ideas what is going on.
