The International Space Station Repeater Active
by Trevor M5AKA

The International Space Station cross-band or U/V FM voice repeater has been switched on.

The downlink is 145.800 FM +/- 3 kHz doppler shift

The uplink is 437.800 FM +/- 10 kHz doppler shift

Please keep in mind that the crew members John and Sergei may be listening and pick up the mic to talk to you.

The ISS repeater can be worked with very simple equipment. To receive it on 145.800 an FM handheld with a 1/4 wave whip is all that's required. On 70cm you need to be able to transmit at least 2 or 3 watts FM into a 1/4 wave whip.

To find out when the Space Station is within range go to the Online Satellite Predictor at
