Talk via new ISS Repeater

ISS 437.800 MHz cross band FM repeater activated. Scouts and Girl Guides with an Amateur Radio License may wish to try to work other Amateur Radios stations via the new Cross Band FM repeater being carried on the International Space Stations (ISS).

Early reports are suggesting that the repeater can be worked while the ISS is in our sky via a dual band hand held and a dual band 2/70cm external hand held beam antenna. Note with-out a directional antenna, reception may be very noisy.

For the technically minded, the ISS FM cross band repeater mode is using an uplink frequency of 145.990 MHz with an access tone [CTCSS] of 67 Hz and a downlink frequency of 437.800 MHz.

Scouts and Girl Guides with out an Amateur Radio License may receive any contacts via an external antenna and a scanning receiver tuned to the down link frequency when the ISS passes over head. For more details see https://amsat-uk.org/2020/09/02/iss-fm-repeater-activated/
