[abdou2014]

here's the original circuit , but you must modify the audio and make a display

Give me this circuit coil and antenna ?i"am not electronist but i build this circuit problam is coil and antenna

[abdou2014]

it's up to you to choose the coil according to your location , or depending on which band you intend to work on , you can not say give me the antenna characteristics

[abdou2014]

unless you want to work on the electric or static field, you connect a telescopic antenna or ionic chamber

[Sreekumar]

Morgans ionic chamber be used?

[Sreekumar]

Or just connect the antenna?

[Sreekumar]

Transmitter or reciver

[abdou2014]

Morgans ionic chamber be used?

Yes of course .
