Welcome to the GB3YT website.

The place to find out information on the GB3YT West Yorkshire ATV Repeater.

GB3YT is located in Mirfield West Yorkshire, receiving on 1276MHz Digital or Analogue, 437Mhz Digital, 5665Mhz Analogue, and Transmits on 1316MHz Digital output only. GB3YT output can also be monitored via the link above, and has been on air since August 2015.


GB3YT is owned and run by G8NZR (Kay) and G8POK (Graham) - we are not part of or affiliated to any groups, clubs or organisations and voluntarily give up our time and resources to provide the repeater. If the repeater goes off-air for any reason, time and access for repairs could be limited, so please bear with us under these circumstances.


GB3YT also has a 144.750MHz talkback input which is re-transmitted on the right audio channel when a valid video signal is being received - this 2m input must also have a CTCSS of 118.8Hz enabled.


Using GB3YT: When using digital inputs, please allow around 5 seconds at the beginning of an over for all the digital circuitry to lock onto your signal. Analogue circuitry will lock onto your video signal and switch the logic fairly quickly. You will know if access has been successfully made, as you will get a repeated audio ident plus 'K' and GB3YT test card J from the repeater when you drop carrier. After aprox 30 seconds, the repeater will switch back over to the outside camera or test card with ident, and an audio GB3YT descriptive ident every 5 minutes. If a signal is being received on more than one input, then GB3YT will display a quad picture and show up to four input signals. The system can not receive simultaneous signals on both 23cm analogue and 23cm digital for obvious reasons.
