First ham radio geostationary satellite transponder active

The geostationary amateur radio narrowband transponder on the
*Es'hail-2 / QO-100* satellite was made available for amateur experimental
use on Tuesday, February 12

*"The Qatar Amateur Radio Society (QARS) invites radio amateurs worldwide
to use the NB transponder in a good manner and make contacts among each
other"*

The 250 kHz bandwidth transponder uses the 2.4 GHz band for the uplink with
the downlink in the 10.45 GHz band and should provide communications over a
large segment of the globe 24 hours a day. Potentially both Brazil and
Thailand might be in range from the UK.



Contacts have been made by running as little as 500 milliwatts of SSB to a
1.2m dish.

You can listen to the Narrowband transponder from anywhere in the world by
using the online WebSDR developed by members of *AMSAT-UK* and *BATC* which
is located at Goonhilly in Cornwall, UK, see
