Hi Jo

As a radio person of some years (SW VHF/UHF) I understand the principles.

I have today ordered a few RF inductors, various values from 50uH to 680.

I'll construct a small portable unit that I can take out with me away from electrical noise.

Here I get a 50 Hz buzz.

I have heard the hiss, I have been using a small LM386 amp to power a speaker.

I am not yet sure how spirit comms can take place, I imagine they use a mode unknown to us, what that is! is the big question I guess.


Thanks for the tips
