ISS on 13cm

I notice ISS is to transmit DVB-S ATV on 13cm.

I don't yet have any kit for that band, only the DVB-S receiver I usually use on 23cm. I have a down converter that would bring 13cm down to around 23cm. Is that likely to be the best route?

Yes,the down converter is probably the only option as you need to use your sat receiver to decode the DVB-S.

Some receivers are only specced down to 2M symbols/s, so 1.3MS/s (SR1300) may be a problem.

I had missed the symbol rate. Wonder why they chose 1.3Ms/S. It might be difficult to find anything (cheaply) that does.
Would be MUCH more interesting if they took up a complete DATV repeater.......

For anyone building their own receive converters for the ISS these bandpass filters look ideal.
