ISS 437.800 MHz Cross Band Repeater Activated

At 01:02 GMT on 2nd September a cross-band FM amateur radio repeater with a downlink on 437.800 MHz was activated on the International Space Station

The ARISS team is pleased to announce that setup and installation of the first element of our next-generation radio system were completed and amateur radio operations with it are now underway.

This first element, dubbed the InterOperable Radio System (IORS), was installed in the International Space Station Columbus module. The IORS replaces the Ericsson radio system and packet module that were originally certified for spaceflight on 26th July 2000.

Upgrade of the D4VHF station VHF and Microwave antenna systems

/

The D4VHF team on Cape Verde Islands have recently made some major changes to their antenna systems for 2-metres, 23cms and 12 cms.

For 144 MHz, they have now installed three crossed 5-element Yagis stacked in a vertical configuration. These will be using Right Hand Circular Polarization and it is hoped that they will be able to make more contacts as the signals will be less prone to fading.

For the 23cms and 13cms microwave bands, they have installed a 1-metre homemade dish. They will be adding an elevation motor so that it can be used for moonbounce on 1296 MHz and 2300 MHz.

They also have an 80cm dish for accessing the QO100 satellite in geostationary orbit (2.4 GHz up, 100 GHz down).
