These include a Gateway on 2 metres, Simplexers (parrots) on 4 metres and 10 metres and a FM/DMR repeater on 70cms.
145 MHz... On 2 metres, there will be a Gateway with the call sign EI2SNG on 145.2375 MHz FM with a 88.5Hz CTCSS. This will allow users access to the Allstar and Echolink networks online (AllStar: 48781, Echolink: 5224).
Using DTMF commands, the 2m gateway can also temporarily connect to both the 4m and 10m systems (thus creating a temporary triple-band service). This will provide (1) Maritime Mobile, (2) portable 2m HT operators, and (3) allstar+echolink users to access these bands with ease.
70 MHz... On 4 metres, there will be a Simplexer (Parrot) on 70.475 MHz FM with carrier access and it will use the call EI4SNR. As outlined above, it can be used in conjunction with the 2m Gateway or on its own as a Simplexer.
A Simplexer operates on a single frequency and records a block of received audio and then relays it again on the same frequency (i.e. like a parrot). This allows users who cannot hear other directly to make contact. It is also a valuable service for any other users in Ireland or overseas who want to check their signals under enhanced conditions.
29 MHz... Like the 4 metre unit, there will also be a 10 metre Simplexer on 29.610 MHz FM. A 67.0 Hz tone is required for access. The callsign will be EI0SNR.
Like the 4 metre unit, this can also be connected to the 2m Gateway. Considering how often the 10m band opens during the Summer months, this might be of particular interest to European stations.
DMR Repeater on 70 cms... It is also proposed to establish a new FM/DMR repeater on 70cms.
Output : 439.700 MHz / Input : 430.700 MHz
FM Access by CTCSS : 167.9 Hz
All of these units will be located near Mullingar in the midlands of Ireland and the map above shows roughly the coverage area.
Additional info from IECRO...
IECRO is keen to encourage increased usage of the 4m (70MHz) and 10m bands. As such, two parrot/simplexers operating on these bands will be linked together to form a cross-band mini parrot network. The 2m gateway mentioned above will be able to temporarily through user requests connect/disconnect to the 4m parrot as and when required, thus providing RF and AllStar/EchoLink
users to access all of the parrots too. What does this mean for the ham community? Well it means
the following dramatic improvements in terms of FM range across the middle of the country from East to West:
4m - 4m
4m - 10m
10m - 10m
2m - both linked parrots
(plus Allstar and Echolink services)
Thanks to Mark EI6HPB for the above info.
