Welcome to the GB3YT website.

This website is the place to find out information on the GB3YT Yorkshire ATV Repeater.


For repeater status - Check the Forum news and status section


GB3YT is located in Mirfield West Yorkshire, receiving on 1276MHz Digital or Analogue, and Transmitting on 1316MHz Digital only. The repeater has now been on air since August 2015, and in 2018, we will be adding 70cm digital receive on 437MHz (2Ms/s). The repeater will then have a total of three inputs.

GB3YT is owned and run by G8NZR and G8POK - 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 is currently a simplex repeater with one input (either analogue or digital) and one digital output, so its use is limited (similar to normal voice repeaters) to one station transmitting through the repeater at once. Talkback on 2m is also re-transmitted on the GB3YT audio channel when a valid video signal is being received along with the 118.8Hz CTCSS tone on 2m.

When using digital, 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 video 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 overlay, and an audio GB3YT descriptive ident every 5 minutes.

Note about current analogue input: If using analogue to access the repeater, you may only get a blue screen after your transmission has ended. This is a slight quirk with video noise induced into the logic which will be corrected when time allows. This does not always happen and you do sometimes get the testcard as detailed above. This does not happen with digital receive. The mark 3 logic to be installed when 437Mhz RX is added should cure this problem.
