Re: 16-turn S-band helix



Hi Vince,

I've been using a 16 turn helix and have been hearing AO40 out to 20000 km.
Tomorrow morning I will hopefully be set up to actually copy telemetry.  Up
to now I've been running portable without a computer available because all
the good passes were either just before work or during lunch.  The latest
AMSAT Journal gives a sample downlink budget based on using the satellite's
high gain antenna which shows an 8 turn helix would give you a 17db SNR.

I'd say give it a try.  You should certainly be able to hear something.
