Repeater Update

EI7FXR Repeater 430.900 MHz at Farmer's Cross Cork City is now back up and running. It had been off air for a few days due to power outage from the recent storms.

Repeaters Update

EI2HHR Helvick Head and EI7CDD Clashmore are both back up and running, EI7FXR at Farmer's Cross Cork City remains off air due to suspected power outage.

Two of our repeaters are off air following Hurricane Ophelia. EI2HHR 2m repeater at Helvick Head and EI7CDD at Clashmore, both are located in West Waterford. We suspect it's probably power outages at the sites. We will know more in the next few days and post updates here.

The EI7BWR repeater on 430.875MHz located at Bweeng North Cork is off air for maintenance and some upgrading. We hope to get it sorted and back on air again soon.

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.

EI7CDD Digital Repeater

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.

EI2DBR Repeater Update

 

Equipment Rack at Devil's Bit

On Tuesday June 6th we upgraded the PA on our 2m repeater 145.650 MHz at Devil's Bit Co. Tipperary. This upgrade more than doubles the power output so users should see an improvment in signal and coverage. We would welcome reports and comments to sirnrepeaters@gmail.com.
The work on the repeater was carried out by Neil EI3JE and John EI8JA.

EI2HHR Repeater Update

On Thursday June 1st we made some changes to our 2m repeater 145.675 MHz at Helvick Head. This included some modifications to the logic and a higher powered PA. Users should see a improvment in signal and coverage from the repeater and we would welcome reports and comments to sirnrepeaters@gmail.com.
The work on the repeater was carried out by Neil EI3JE and John EI8JA.

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; https://brandmeister.network/?page=repeater&id=272002

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.

The problem with the link audio on EI7HXR repeater has been resolved, turned out to be a faulty capacitor. Work was carried out on Tuesday 11/04/17. Thanks to Neil EI3JE.

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.

EI7MLR repeater Mt. Leinster

Users of the EI7MLR repeater on  Mt. Leinster may be experiencing a reduction in signal, this is due to suspected antenna problems which we hope to recifiy over the coming weekend weather permitting.
Updates will be posted here and on the Facebook page.

IRLP update

The IRLP node is now back to normal operation, thanks to Eoghan EI5HBB.

The IRLP Node is currently not working correctly due to some networking issues. We hope to have the issue sorted shortly. Thank you for your patience.
