Limerick Radio Club 70cm Repeater

The Limerick Radio Club's new 70-centimetre repeater has
completed its testing phase and is due to be installed
on site this week between the 11th and 15th July.

Good 70 cm coverage is expected in West Clare, most of Limerick and parts of East Kerry, Tipperary South Riding and
North Cork. Low power "rubber duck" handheld access
should be available in Shannon Town and Limerick city.

There may be mobile or base station access in Mallow,
Blarney, Tralee and Tipperary Town. Please send reports
to Mike "ei9feb at eircom dot net".

The site is not Keeper Hill. The actual location will be announced in a few weeks, so have fun guessing the QTH and trying to access it!

The settings are 433.125 MHz for your receiver and
434.725 MHz on your transmitter (standard RB5, 1.6 MHz
plus split) with CTCSS or PL Tone of 103.5 Hz. The RB5
repeater is permanently linked to Limerick R5 repeater which is on 145.725 MHz with 600 kHz minus shift which uses 1750 Hz tone burst to open.

Listening on 2 metres, you can tell if a QSO is with a
70-centimetre user as a distinctive "tuning fork"
mechanical tone burst will preface every 70 centimetre
transmission. 2 metre to 2 metre QSOs sound as before.
Listening on 70 centimetre, a 70 centimetre QSO has no
preface, but a tail of three beeps, the first is the 70
centimetre "pip", the second indicates the 2 metre link is active and the third is the pip from the 2 metre repeater. It is after a slight pause (in the 2-metre repeater controller), so wait for it or 2 metres will "time out". A 2 metre QSO heard on 70 centimetre side simply has the 2 metre pip at the end of each over, no 70 centimetre pips.

On "70cm RB5" any DTMF tones are "blanked" by the
controller. If you need to send DTMF via the controller
prefix it by "5". If you want to test your DTMF keypad on 70cm, press "# 5" and you will hear the ident in CW.
To echo any keypad DTMF, press "# 8" and it will echo in CW. This feature turns off after about 45 seconds of no carrier.
