Your views! of what possibly were about all those switches or any other unrelated or related knowledge you would like to depict here.

[Reply #1 on:]

My guess is misdirection, Stanley. The giant panel of switches gave the FBI something to look at. Also, my name is Mr. Burgess and I make fake bombs for airsoft and paintball games. This explains the FBI van that has been parked outside my house for the past week.....

I mean what you think that, at that time that is in 1980's which wireless technology they were using gradually most probably radio but which modules? they said that if extortion money isn't received then they will blow up the bomb so gradually there would be some wireless control! or I heard wrong?

and The extortion folks also told that they can't change the location! so is there any force sensors etc used?
may be!

Most likely analogue - a simple DTMF decoder and a couple of walkie-talkes.

Edit: early analogue multichannel R/C used to use resonant reeds that vibrated at different audio frequencies to switch the different functions.

Early Westinghouse remote sender/receivers over telephone lines used something similar; the public saw this in action with the "robot" Electro (as well as earlier Westinghouse "robots"). Basically tones sent down the lines to vibrate tuning forks that closed switches. Used for early industrial remote telemetry and control systems - this book is a great history on these machines:

A very good addition to one's knowledge bank.
