Conditions are up!

Conditions are very favourable at the moment with a contact being made with 2E0AXZ in IPSWITCH, SUFFOLK direct on RF at 17:10 today! Good luck to you all and please let us know of any DX you work via GB3DT as we would like to hear the results.

Planned Maintenance

Rich (G0ZEP) will be carrying out work on both GB3DT and GB7CM on Saturday 22 October. Hopefully noise on both repeaters should be reduced. Throughout the morning either or both of the repeaters may be down while work is carried out.

Signal reports are always welcome.

Experimental Change 2

GB3DT is undergoing additional trials and tests over the following few days from 1500hrs on Wednesday 5 October to approximately 1000 Monday 10 October.

For this period, the repeater will be in AUTO <> AUTO mode so if C4FM is received, it will be re-transmitted.  We would be interested to see how Analogue and Digital interact as well as general signal reports. It would be appreciated if C4FM users enabled AMS so should an analogue user call in and that Analogue users enable CTCSS on their Receive signal (to stop the digital hiss that is received when digital is used).

Any test reports would be welcome and should be sent to

Planned Power Outages

There will be mains power outages to various parts of the GB3DT repeater  systems over the coming few days. Both the repeater and Echolink nodes have backup battery power so should continue to function normally.

GB3DT website goes live

The GB3DT repeater group have recently seized the opportunity to create a website (www.gb3dt.co.uk) to enable users of the repeater to keep up to date with developments of GB3DT.

Further functionality will be added over the coming weeks as well as updating all the history behind GB3DT. If you have any comments about the website or the repeater itself, please let us know on air or by e-mail.
