A known and previously described problem with receiving IC-905 FMTV signals with a commercial satellite receiver.
I really want to receive IC-905 signals with an satellite receiver as well !.
I found some time and upgraded my Pace MSS138G receiver.
I still had a homemade VRKL2.0 from Josef Frank Elektronik in storage from the old days.

It can nicely regulate video signals between 0.3 Vpp and 2 Vpp to 1 Vpp and has three video outputs.
This is what it looks like when installed in the Pace receiver.....

Sent with IC-905 FMTV FIL1 - This is what the signal looks like before and after the amplifier distributor....

IC-905 ---> I've been waiting for some time ( over a year ) for some indication from ICOM that they'll be supplying a genuine AV cable.
Unfortunately, it doesn't look like it will be available.
I made my own cable with a 75ohm video coax and a 600ohm audio coax + gold-plated plug to minimize quality loss.

Feedback from other IC-905 users:
A TX ON/OFF button on the display would also be nice, especially during contests when you need both hands for other things,
and holding the Microphone PTT button at the same time is impossible.

Hi
Regarding front button Tx on/off that is possible. We have set the Vox to preform that function as customizing the button is available in the menus.

A simple 3 pole 3.5mm to stereo audio cable can be used for the video and audio input. Or if you must have two seperate grounds and a 4pole 3.5mm there's this available ready made
