Internet connected only repeaters

Post by g8gtz » Fri Feb 03, 2017 10:00 am

Mike G0MJW said in a separate topic - http://www.batc.org.uk/forum/viewtopic. ... 827#p11739
The problem with a repeater is the license takes ages and not to mention all the other work. So, how about a network of web connected receivers that stream to the BATC streamer?
I have checked with the RSGB ETCC committee and we can see absolutely no reason why this cannot be done to encourage activity where there is no repeater or an NoV is delayed - it is no different to all the web SDRs which are now available.

In fact, the GB3HV group did exactly this for over 3 years whilst we waited for the NoV and there are already 2 similar systems on BATC.TV - one from Enfield in North London and the G8LES link system.

So if you are thinking of putting a repeater on air and want to do long term tests or if you are waiting for an NoV, we would be happy to put up a channel in the repeater section on BATC.TV. As these systems will not be able to use an allocated callsign, I suggest a system where we use the postcode of the site as an identifier.

These could be very simple units - particularly as we now have the Portsdown unit to stream to batc.tv you don't even need a PC.

Thoughts?

Hi Noel

I'm very interested in the possibilities of this but as usual have several questions...

I understand that a Pi running Portsdown software and an Easycap can be used to provide a stream to the Internet but that requires a video input. We have 3 Portsdown builders in this area (myself included) and no analogue, so a digital receiver would be essential. Would you recommend a Freesat receiver and Alford slot (with preamp) as the easiest way to go about this or something completely different? If a Freesat rx is there one recommended that will power up on a selected frequency if power fails?

73 Dave.

Hi Dave,

Looks like I missed this post but answered it on another thread.

If you are looking for a low power logic / switching system for a simple ATV repeater it may be worth taking a look at the RPi based kits produced Dave G8PUO (GB3JT keeper). I'll say it before Dave GKQ does, it can't be run on the same RPi as a Portsdown streamer but could make a neat system based on 2 RPis.

Now bookmarked, that certainly looks handy if we ever get to full repeater status.

Thanks.
