Ham Video Commissioning now scheduled

The Ham Video transmitter, which is stored in the Columbus module of
the International Space Station, will be installed March 6, 2014. The
transmitter will be powered on briefly, just the time needed to check
that the connection cables to the antenna, to the power supply and to
the camera are installed properly. All control LEDs nominal, the
transmitter will be considered ready for Commissioning and will be
unpowered.

The first Commissioning step is planned March 8. Michael S. Hopkins
KF5LJG will power on the Ham Video transmitter in configuration 1:
ARISS antenna 41 Frequency 2.422 GHz Symbol rate 1.3 Ms/s The
transmission will start shortly before the pass of the ISS over the
Matera ground station in south Italy at approximately 13.29 UTC.

The ground station will stream the video over the BATC server
http://www.batc.tv/ .Please select Member Streams and ISS.
During the pass, different configurations will be tested with ARISS
antenna 41.

After the pass, the Ham Video transmitter will stay powered on in
configuration 1 till the following Commissioning step, which is
planned Sunday March 9, 2014 at approximately 12.40 UTC.

For about 24 hours, the DATV signal will be transmitted permanently,
but the camera will be powered off. The reason is, that the camera is
battery powered and no provisions are made for frequent battery
replacement. This mode is called “blank” transmission.

During Commissioning step 2, different configurations will again be
tested, this time with ARISS antenna 43. The Matera ground station
will stream the video over the BATC server.

Possibly, blank transmissions will occur in the period between
Commissioning step 2 and the following step, which is not yet
planned.
We will circulate Ham TV Bulletins to inform on blank transmissions.

Reports on reception of blank transmissions are very welcome.
