Does anyone know what hardware will be used to send the SSTV / Robot 36 images?
Specifically does it send the VIS code at the beginning of the transmission?

Good Morning Simon,
The hardware will be the Kenwood VC-H1, installe near the Svezda module window. http://www.kenwood.com/i/products/info/amateur/vch1.html
Can you ADD this mode Robot36 on Digital Master SSTV before the Soyuz launch in 12 Oct?
Thank you!

Hi,
Thanks for the info, Robot 36 support being tested already.
Some specs on this device: http://www.svs.net/wyman/products/vc-h1.htm
Still looking for VIS code info...

Looks like the camera supports VIS codes which makes life much easier. Robot 36 is a 'tricky' mode to decode at times.

Hi Simon,
I've just been on the phone with a ham who has the VC-H1 and he just took a picture and sent it with robot36. It sounds like there only is a 2300Hz tone at the beginning. I don't own one myself, but according to him there is no setting to enable or disable VIS in a menu. Maybe the VC-H1 selects VIS-mode on the "newer" modes like scotty and martin.
The german website seems to mention autoselection of the correct mode on reception and uses this mode to determine the transmit mode for the next picture. But then again, my german is not that good...
Good luck and keep up the good work on HRD!

Hi,
I found the handbook online - I think VIS is always sent and used for receive detection as well.

Hello all,
I'm planning a new antenna system and planning on using an SSB preamp on the 430 downlink side. The 7000 uses helical bandfiltering. My antenna separation will be on an 8' fiberglas boom. Will desense be an issues? Should I plan on using a bandpass filter such as a duplexer?
Thanks and 73 de Tim, K4SHF

Hi Tim,
The SP-7000 has a pair of back-to-back diodes on the input to protect the gasfet BEFORE the helical filter so it is pretty easy to overload it. I would guess that 8' is not enough seperation and you will need the duplexor so you should probably plan for it.
