MMDVM Repeater Project

Our MMDVM experiments are on going and all modes are running as they should. After been on test for a couple of months in Waterford City we now have the repeater installed at it's new permanent location in West Waterford. The installation took place on Friday July 28th. On site were Neil EI3JE, Gareth EI7FZB, John EI8JA and John EI8IR.

Information regarding the repeater; how to access and use the various modes etc. can be found on the Digital page. This is the knowledge gained by us so far in the project should make accessing the various modes somewhat easier for potential users.

MMDVM Digital Repeater Project

The past couple of years has seen an increase in both interest and activity in digital voice modes here in EI and with prices of tranceivers for the various modes especially DMR decreasing and a lot of rigs having digital capability more people are trying it out, with this in mind we decided to look at the latest development in digital radio the MMDVM, an open-source Multi-Mode Digital Voice Modem. This allows radios like the Motorola MTR2000 which we currently use on our analog network to be used on digital modes like DMR, Fusion, DStar and P25.

Since early March we have been busy experimenting with the MMDVM and have interfaced it with a UHF MTR2000. This has taken a few months to complete with configuring the various modes and sourcing the tranceivers to test them. In that time we have obtained a licence and location for the repeater and plan to put it into service from a hilltop site in West Waterford in the coming weeks which should provide coverage from Cork City to Waterford City. It's callsign will be EI7CDD and it will operate in modes DMR, DStar, Fusion and Analog (digital modes will have priority over analog) on 439.650 MHz with a shift of -9 MHz (DVU52) which is one of the newly allocated 70cm channels for digital voice in Ireland and the UK.

It is currently on test from Waterford City and connected to the Brandmeister DMR network;

We plan to post information regarding the repeater; how to access and use the various modes etc. plus some photos of various stages of the project over the coming weeks. The group's email address is sirnrepeaters at gmail dot com should you have any questions.

EI7MLR repeater update

(Photos show the equipment and antennas) 

 Last Saturday February 4th we managed to visit Mt. Leinster to do the necessary work on the repeater antenna. We also replaced the duplexer and increased the power output. The complete installation was installed in a 19" rack. Users of the repeater should see a big improvment in the signal and coverage.
The work was carried out by Neil EI3JE and John EI8JA.
