ARLA/CLUSTER: ISS HamTV 2395 MHz blank transmissions

[João Costa > CT1FBF]

Presently, the Ham Video equipment on the International Space Station
is permanently transmitting a 'blank' image and no audio

It is in configuration 3:
• ARISS antenna 43
• Frequency 2395 MHz
• Symbol rate 1.3 Ms/s

Transmission will continue in this configuration till the end of the week.

On Sunday, March 23, Ham Video will start transmitting in
configuration 4, i.e. 2395MHz and 2.0 Ms/s.

Due to SpaceX docking and related operations, Ham Video blank
transmissions will come to an end March 31.

The last commissioning step will be planned in April or in May 2014.
We will keep you informed on the precise date and time.

Reports on reception of blank transmissions are very welcome.
Reports can be filed via this webpage:

Participants using the Tutioune receiving software can record as well
as stream detailed parameters of the received signal. Please see:

Thursday March 20, three ground stations tested chained reception of
Ham Video signals. Jean Pierre Courjaud reported on this experiment on
his website. The report is available at
