Aurora wireless ?? - UK Vintage Radio Repair and Restoration Discussion Forum

rbm1973 · 16th Mar 2016, 5:15 am

is there any way to run the aroura wireless around the house ie a low power transmitter so i can keep the aroura in one room and receive signals via set top aerial ?

I think the Aurora has video and audio outputs as well as the RF output (someone who actually has one can probably confirm). If so, I would imagine that it would be possible to feed these into a video sender (available for around £25 each - put "video sender" into your favourite search engine) even though they are intended for 625-line signals, as long as they don't try to do clever things with a 625-line video signal. This would at least use an RF channel officially dedicated for this purpose - unlike feeding the RF output of the Aurora into an aerial system, which would be in breach of regulations.

See this thread to read why this is not a good idea: https://www.vintage-radio.net/forum/...d.php?p=822763

The Aurora has video and audio inputs, but only one RF output. there are no other outputs.
I did try the aurora by feeding the RF in to a set top aerial, but the results were rather poor. Far better to have a wired distribution setup and avoid all the problems with harmonics.

Thanks, Mark, for confirming that. As I say, I don't have an Aurora myself. I use a Domino, which does have a video output (audio, of course can be taken direct from the source).

Given the absence of a video ouptut, my suggestion falls at the first hurdle. I agree that a wired setup is the best way forward.

You could use an aerial distribution amplifier. The input may need a bit of attenuation.

My Aurora has both video in and converted video out sockets. The video out socket is a yellow phono socket beside the F connector.

How would you connect the video sender receiver to the 405 line TV? 405 line TVs don't have scarts or video in sockets.

There are units that have composite video and mono audio inputs, they actually transmit via an extendable rod aerial. The problem is they transmit on UHF.

Most legitimate! video senders transmit in the low microwave region - typically around 2.5GHz and need to be used with corresponding receiver - in this application each receive point would require a receiver for video sender feeding a system 'A' modulator. This requires quite a bit of 'kit' but is eminently doable - video sender Tx & Rxs are readily available on auction sites - the system 'A' modulators less so but a trawl of this site, among others will yield some ideas. This may seem like an overkill but if you really need a 'wireless' solution this is the way forward

There are plenty in this part of the world that transmit system B on VHF, but the FM sound isn't going to be overly helpful! I sent over a few that worked on channels NZ2/3 a few years ago to Kat Manton (I think she's still around on the forum) for some system A experiments, but I know at least one of them ended up feeding system B to a European set!

Not so sure about that: https://www.vintage-radio.net/forum/...d.php?p=735637

Also at system I. But most important is that they are not legal to use in the UK.
