Apart from power budget issues and Doppler the real killer will be the very high noise level on 2.4 GHz.
In urban areas you can expected to receive strong WiFi signals across all of 2402-2450 almost regardless of where you beam. Any signals from a satellite would need to be strong enough to overcome this interference. 5 GHz is likely to suffer a similar problem in a few years as more use is made of that band for WiFi etc. 73 Trevor M5AKA _______________________________________________ Sent via AMSAT-BB@amsat.org.
