Got me one of these.

What are you trying to do with it?

I use something similar to get PC output into a distributed TV system.

PC – VGA to S video converter – S video to coax modulator – distributed TV board (could be an individual PC).

I see what you mean, or rather I didn’t see so googled it.

https://www.radiolaguy.com/info/tv.htm reckons you need channel 3 or 4 and that one starts at 21.

If you can’t get out of it and don’t have a use for it I’ll have it off you.

Now doing my second project of this type (it’s to do with prison TV) so hopefully there’s a good chance there will be more.

Lee, the way that is intended, you will need to select analogue TV. If you have digital only, you are out of luck. Our two TVs still have analogue available, but of course no signals.

I have something similar (but composite video + audio only) that I used to use years ago to send stuff upstairs from sources downstairs, such as the BSB sat receiver I bought, new and cheap, after its demise was announced.

Dave, that is interesting, supply analogue only TVs, so no chance of standard digital TV channels. However, if I was inside, I would want a pal to get one of these modulators, park outside in car, and transmit on a different channel. We could have messages sent, porn films, anything!

I used to have a CTV signal generator which could output a test pattern, or could be modulated with sound and video. Attach that to an aerial and you can transmit a fair old distance.

Les.

The TVs don’t have aerials and the distribution system is locked away in the loft.

Park outside in a car with a portable analogue TV transmitter :whistle:  Not suspicious at all. No way the CCTV camera operators would think to check that out  😉

They don’t supply analogue TV for any other reason than it’s just what they have. An ancient system.

Isn’t that what the digital boxes do though, convert the digital input into an analogue output for the TV?

A wireless network links them all up and we use VNC to copy content to the distribution PCs and control VLC. That way each block can run it’s own content and there’s no single point of failure as there would be if we’d gone down the streaming route.

You might find it easier to set up separate folders for each block, and sync them to the distribution TVs, so there’s less manual work needed  :good:

Scart of itself should not be a problem. There are plenty of cheap scart adapters on the market.

Lee if your new adapter fails to work, I have a spare digital->rf coax adapter that I used to use to pump the signal from a HD+ Sky box around the house. PM me if you want it. I no longer need it as I moved over to Sky Q.

Still, I have to get me a vintage TV before anything

Tbh I do not understand that statement. Unless you have a very new TV, most support rf in (i.e. terrestrial TV broadcasts) . You may have to ‘tune’ in to any stream you pipe to it but the stream is found normally somewhere between channels 35 and 42.
