This is a fucking mess. Engineering students and radio hams do a far better job of rigging an EXPERIMENTAL setup. This is not experimental. This is supposed to hold up in battle conditions.
EMP? Hacking? Impossible. Everything is perfectly shielded except for the tangle of white wires on the left and the open rotary switch at upper center. No chance for signal leakage at all.
Note especially the circled mess of adapters and readapters and rerereadapters.
Reminds me of my crude Tinkertoy phonograph which isn't meant to hold up in any conditions at all. It's just a bit of fun for me.
