What do we do?

We operate the following repeaters, beacons, digipeaters and gateways.


GB3TE - 2m voice repeater

GB7TE - 2m D-Star repeater

MB7TV - 2m SSTV repeater

MB7UA - 2m APRS digipeater

MB7UH - 2m APRS UI-View digipeater

GB3CE - 70cms voice repeater

GB3CL - 70cms voice repeater

GB7CL - 70cms DMR repeater

GB3CZ - 13cms FSTV beacon

GB3PKT - 10 GHz beacon

GB3PKT - 24 GHz beacon


In addition to this we run QRSS and WSPR stations and some members of the group run other services, not specifically linked to the Martello Tower Group.  We also have an ADS-B receiver situated on the roof of the Tower.

How is all this paid for?

The members of the Martello Tower Group all make a monthly contribution into the club funds.


Our regular outgoings are:


Internet costs for GB7TE (D-Star) at the Holland Haven site.

Insurance - Every GB/MB callsign incurs a cost.

Regular maintenance, aerial replacement, aerial riggers, etc.


Our special events such as GB5RC are independently paid for out of the members pockets, we don't use club money for those whatsoever.

How you can help

We barely have enough money in our accounts to keep things going.  All it will take is an unexpected equipment failure to force stations off air.


If you use any of our services, please consider making a donation to the Martello Tower Group - A one off donation is great but if you can manage a small donation of (say) a fiver a month then that will make a big difference.


You can donate either via post to the repeater keeper:
