The Digital HamTV transmitter on the International Space Station will change frequency to 2395 MHz on the weekend of March 15/16.
HamTV Bulletin 9:
The Ham Video transmitter commissioning steps 1 and 2 were performed as planned. Working together with ESA / B.USOC, the ARISS team in Matera did an excellent job.
Saturday April 8, four configurations tested with antenna 41.
Sunday April 9, six configurations tested with antenna 43.
Both ARISS L/S-band antennas are operational in S-band. Reports from ground stations during blank transmissions will allow further analysis of their performance and radiation characteristics in space.
Recordings of signals received during commissioning steps at Matera ground station will be made available on the BATC server.
In Livorno, Ham Video manufacturer Kayser Italia received excellent signals with a 1.2m dish. In Casale Monferrato, the ARISS telebridge station also received good signals with the same type of antenna.
Recordings can be viewed with VLC software. Please select 16/9 image format.
Presently, Ham Video is transmitting permanently a “blank” image and no audio in configuration 1:
* ARISS antenna 43
* Frequency 2422 MHz
* Symbol rate 1.3 Ms/s
This blank transmission will continue till the end of the week.
Next week blank transmission is planned with antenna 43 on 2395 MHz and 1.3 Ms/s. The frequency changeover will be done Saturday 15 or Sunday 16 March. All Ham Video frequencies have been notified to ITU as ISS – ARISS.
Reports on reception of blank transmissions are very welcome. Reports can be filed via this webpage: http://www.spaceflightsoftware.com/ARISS_FSTV/submit.php
Participants using the Tutioune receiving software can record as well as stream detailed parameters of the received signal. Please see: http://www.vivadatv.org/
Blank transmissions will continue till the next commissioning step, which is planned April 12, 2014. We will announce configurations in due time.
Thank you for your participation to the Ham Video testing campaign.
