Hi Kev,

The active FM birds are AO-51, SO-50, AO-27, and ISS. I think SO-67 and HO-68 are sometimes available. I'm sure someone will correct me if I have omitted any.

You can get their frequencies by clicking on each one on this page: http://www.amsat.org/amsat-new/satellites/status.php

The doppler shift will vary throughout the pass, so there is no one position that works. ISS has a VHF downlink that varies +/- 3Khz (approx) during the pass. The others have UHF downlinks that vary +/- 15Khz (approx). It will always be higher at the beginning, on frequency when the sat is at max elevation, and lower at the end. Being FM, the tonal quality won't change, the signal will just get weaker as it leaves the passband, so periodically tune around for maximum signal strength.

Hello there. Would someone be kind enough to give me a list of frequencies with doppler correction for the Fm birds. I have Ao51 but not heard for a while . Its for easy programming into my Ht.
