Hello

Is there a computer program I can run to model a turnstile antenna for 2m / 70 cm ?

//

Falconsat-3 reception, should i turn on or off the “audio” filter for 9600 Baud G3RUH ( 3 kHz)

Pass band is about 8 kHz with doppler tracking - working dead on the bird

I need to loose this vertical antenna - it just sees the horizon
