Limerick Radio Club 70cm Repeater
The Limerick Radio Clubs new 70-centimetre repeater has completed its
testing phase and is due to be installed on site next week between the
11th & 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.

More Repeater News
The EI2WRC voice repeater at the Ridge of Capard had been off air
recently and underwent some improvements, thanks to Neil EI3JE and John
EI8JA. The audio has been improved and the repeater sensitivity has been
fine-tuned for optimal performance. The EI2WRC Voice Repeater is part of
the Southern Ireland Repeater Network.
The Cork Repeater Group is at present in the process of upgrading both
the 2 metre and 70 centimetre repeaters, and wishes to apologise for the
interruption of service, it is hoped to have both back in full service
soon.

2 Metre Beacon in The Azores
A new 2-metre beacon has been installed in the Azores with the call
CU8DUB/B on 144.420 MHz. Located at 700 metres above sea level it runs
70 watts to a 4 element Yagi beaming 60/70 degrees, the locator of the
beacon is HM49KL a distance of about 2150 km from EI. The Azores has not
been worked on 2 meters from EI. It should be possible to copy this
beacon via meteor reflections especially in early morning time. Already
CT1HZE has copied the beacon via tropo the evening the beacon was
installed, at a distance of 1950km.

Alcock & Brown Replica Flight
The Alcock & Brown flight landed safely at Ballyconneally Golf Club on
Sunday around 16.30 hours not far from the site of the original landing
and the old Marconi Radio Station. The event was covered by Sky News,
CNN & RTE a huge crowd of well behaved aviation enthusiasts welcomed
Steve and Mark. The Clifden Chamber of Commerce organised much of the
Irish side of the flight and all the festivities, Steve Fossett's own
ground crew did the landing preparation and PR for the event, festivities
continued well into the night and Monday was another big day. The Irish
Air Corps did a superb fly by, maintaining a careful distance from the
more cumbersome approaching vintage aircraft. After a ground roll of
only 100 metres, the Vickers Vimy came to a majestic and perfect stop.
Local and HF Radio communications played a big part in the co-ordination
of the event.

Howth Peninsula Festival
Last weekend, a special event station, EI2HPF, was QRV from the Vintage
Radio Museum in the Martello Tower during the Howth Peninsula Festival.
The station had many contacts on vhf and hf with the emphasis on CW. The
operators were Joe EI4FV and Tony EI5EM. The curator, Pat Herbert was
delighted with the number of visitors to the museum. Pat was kept busy
welcoming visitors and showing them around his Aladdin's Cave, while Joe
and Tony demonstrated the station and answed questions about the hobby.
It was great to see so many experimenters among the visitors. Andy,
KA2VXA, who is stationed in Germany, dropped in on Saturday. Se n, EI5GH
helped out on both days. John, EI7GJ kindly bought ice cream cones for
all on Saturday before QSY-ing to NDR. Eoin, EI9HZ took the trouble to
stay and help with dismantling the antennas. Ben, EI4IN, who was working
in Howth on Sunday, took a break to stop by for an hour or so. Other EIs
who dropped in were, Tom (EI8BX), Andy (EI4ERB) and Jim (EI4GZ) with xyl
Joanna. Thanks to one and all.
It was a very enjoyable, successful and worthwhile operation. It is hoped
to have a permanent station in the museum before too long with its own
call-sign. So watch this space for further news. The museum is open every
day from 11 until 5 until the end of October when it will only open on
weekends. The website is www.qsl.net/ei5em/museum.html which will shortly
be updated with photographs taken last weekend.
