New 70cms repeater in the west of Ireland to improve coverage of the Southern Ireland Repeater Network

The Southern Ireland Repeater Network is made of seven interlinked repeaters on 2-metres and 70-cms and covers the southern half of Ireland. The coverage map as of June 2020 is shown below...


There are now plans to fit a new 70-cms repeater on the summit of Mahera in Co.Clare in the west of Ireland. This is an excellent site in terms of coverage and is one of the main transmission sites used by the state broadcaster RTE for radio and TV.

An approximate coverage map of the new proposed 433 MHz repeater is shown below....


The most significant change is that it will add Galway City to the Southern Ireland Repeater Network which is a welcome development.

The eastern part of Limerick City should also be covered although Woodcock Hill will screen signals to the western part of the city.

The coverage map also suggests very good coverage of the main road from Limerick to Galway as well as the eastern part of Co.Galway and the part of the midlands.

From my understanding, the new repeater will be installed once the travel restrictions for COVID-19 are eased.

Zello Network Radio connection to the Southern Ireland Repeater Network

There has been a lot of interest of late in 'Network Radio' and the most popular app for this is probably Zello. (See previous post)

In the last few days, the Southern Ireland Repeater Network has been connected to the Zello network. In effect, this allows people to access the repeater network over the internet.

From my understanding of it, anyone can listen to the SIRN on Zello but only licenced radio amateurs are allowed to gain access.

Here is some info from one of the repeater group moderators...

Hi all, I’m delighted to announce that the Southern Ireland Repeater Network now has a Zello gateway. This is a very comprehensive network which covers most of the country with VHF, UHF, 4m, and also has a DMR link.

Please visit our pages for all the info and we welcome all licensed amateurs and listeners.

The same moderator structure as used in network radio is in place just add as a friend and you will be trusted as a friend and have full access to most of EI on RF! As these are RF amateur repeaters it will be obviously for licensed holders only though non licensed operators can listen.

I believe this will be one of the first Repeater network gateways to be accessed through the Zello network and we’re very excited to be able to provide this facility which will enhance more activity.
Thank you very much de John EI2HW.

SIRN Activity... The Southern Ireland Repeater Network covers roughly half the island of Ireland and consists of two repeaters on 2m and five on 70cms. It is also connected to the DMR network on TG27240.

The repeater network can be pretty quiet considering the number of repeaters on the network. The busiest period is usually on Tuesday evenings when the IRTS news is read out at 9:30pm local time.

The EI activity evenings on 2m and 70cms are on the first two Tuesdays of every month and it's worth having a listen then as well.

If you are calling in via Zello then be sure to give your callsign and call more than once if you get no answer at first. A number of people may well be monitoring or scanning and may not hear you first time around.

Zello to Zello.... Just remember that if you do access the network via Zello then you are tying up a whole RF repeater network. If the person you are talking to is also on Zello then that conversation can be held on Zello instead.

Remember that it is not just another Zello channel, it's a means of accessing a repeater network in Ireland from the Zello network.

Getting on Zello.... It's very easy to get started on Zello. If you have a smartphone or tablet then just download the app for free and then set up a Zello account. To get on the Southern Ireland Repeater Network, just go to the this page.. https://zello.com/channels/k/e8Tb1 or scan the QR code that is shown there.

Donations for the Southern Ireland Repeater Network



The Southern Ireland Repeater Group maintain an impressive repeater network in the south of Ireland. They have no fewer than 7 voice repeaters scatted across the 2 metre and 70cms bands as well as two digital repeaters in Waterford.

While VHF and UHF activity remains at a low level, this network is largely responsible for much of the activity on the higher bands.

I noticed recently that they have added a donate facility on their website to help maintain the network. Have a look if you wish to contribute.... http://sirnrepeaters.blogspot.ie/

Southern Ireland Repeater Network...2m & 70cms

Since I returned to the radio, I have been listening to the 2m and 70cm bands. While the level of activity on FM seems pretty low, the repeater infrastructure on the bands is very impressive.

The largest of these is the Southern Ireland Repeater Network which links up multiple repeaters. i.e. a signal on one repeater appears on all the others.

The coverage is shown below....



2m Repeaters:

A
Callsign:   EI2DBR
Location:    Devil’s Bit, Co. Tipperary.
Locator:    IO62BU
Output:   145.650MHz
Input:   145.050MHz
Shift:   -0.6MHz
Access:   Carrier

B
Callsign:   EI2HHR
Location:    Helvick Head, Co. Waterford.
Locator:    IO62EB  
Output:   145.675MHz
Input:   145.075MHz
Shift:   -0.6MHz
Access:   Carrier

70cms Repeaters:

C
Callsign:   EI7MLR
Location:    Mt. Leinster, Co. Carlow.
Locator:    IO62OO
Output:   430.950MHz
Input:   438.550MHz
Shift:   +7.6MHz
Access:  156.7Hz

D
Callsign:   EI7WCR
Location:    Carrickphierish, Waterford City.
Locator:    IO62KG
Output:   433.275MHz
Input:   434.875MHz
Shift:   +1.6MHz
Access:   Carrier

E
Callsign:   EI7FXR
Location:    Farmers Cross, Cork City.
Locator:    IO51SU
Output:   430.900MHz
Input:   438.500MHz
Shift:   +7.6MHz
Access:   103.5Hz

F
Callsign:   EI7BWR
Location:    Bweeng, North Cork.
Locator:    IO52OB
Output:   430.875MHz
Input:   438.475MHz
Shift:   +7.6MHz
Access:   103.5Hz

One obvious problem is that one conversation can tie up multiple repeaters but it doesn't seem to an issue as the activity levels are pretty low.

It's certainly a big change from before when there were just simple stand alone repeaters on 145 MHz that didn't connect to anything else.
