The AO-27 FM satellite is back on the air! AO-27 is an FM V/U Mode satellite that was launched back in 1993. The satellite’s Amateur Radio payload became inoperative about 7 years ago due to an internal communications failure. Thanks to some great work by Micheal, N3UC who was one of AO-27’s original designers, the satellite is back on the air on a limited-time basis (4 minutes, twice per orbit over the mid-latitudes).
I was able to make my first contact through AO-27 this morning. The contact was with AI9IN in Indiana, USA. I’m looking forward to making more contacts using this satellite in the near future. Here are the current frequencies for the uplink and downlink (no PL tone is required):
- Uplink – 145.850 MHz FM
- Downlink – 436.7975 MHz FM
It’s great to have yet another FM satellite that we can all use. I hope that other satellite operators will give AO-27 a try.
