Basic
Operating Guidelines
Please
listen on the frequency before transmitting; as this
is a simplex gateway and not a repeater, you may not instantly know
whether
someone local is currently transmitting to it. If you listen long
enough, and
someone is already using it, you may
well hear a couresty-tone , which shows
that
they have dropped carrier, and then in a few moments you may hear the
other
side of their QSO. Having listened, the next step is to see if the
gateway is
active – please look at the list of commands below. You will not be
able
to “blip it up” like a repeater, but if you press your PTT and send
“08” in
DTMF tones, you should hear whether the link is on and connected. You
may also
hear “EI2MOG-L” sent in Morse Code, as
there is a
beacon facility here (in fact it is a licence requirement), or some
other
identifying station announcement.
Once
you are sure that the gateway is not being used, you
can use it to connect to any conference, repeater, link, or individual
currently on-line, by pressing your PTT and entering the node number
with your
DTMF keypad. You can find out who is currently on-line here www.echolink.org/el/logins.jsp
. Let me explain a little about the terms “conference”, “repeater”,
“link”, and
“individual”.
CONFERENCE: a
server-based facility in which two or more Echolink
stations can “sit”. Usually these facilities are made for a specific
purpose,
e.g. to group together several repeaters and/or links, maybe for
geographical
or linguistic reasons. Transmissions made via one repeater or link in
the
conference will be heard over all of them. EI2MOG-L may well spend
periods of
times sitting in a conference (often it will be the IRELAND conference
–
see www.echoireland.com ); I
will
have decided when to do so, but the link’s presence there will be at
the
discretion of the sysop (system operator) of the conference. If he or
she does
not like the way people operate the link, it could well be muted or
excluded.
If there is no traffic currently on the conference, you may still set
up a
connection, using your DTMF tones, with another Echolink
user, but I would suggest putting out a CQ call, to see if anyone is
listening
anywhere.
REPEATER:
just like the ordinary repeater where you are located, but with an
added Echolink facility. Local mobile
traffic takes priority, and
you may find it difficult to break in to an established QSO; but once
you have
been noticed and called in by one of the stations local to the
repeater, they
will make it clear when they are putting it over to you. Leave a few
seconds’
gap when it is put over to you, to compensate for internet time lags
and for
the repeater logic to re-set itself (i.e. give its “k” to local
operators
– which you might not hear).
LINK: If
you’re on EI2MOG-L you’re on a link! A link receives your signal on a
simplex
frequency and sends it via the internet to a remote station; then it
transmits
back to you, on the simplex frequency, what is coming down the internet
connection from the remote station.
INDIVIDUAL:
Individual stations are always computer based, and are not on the air.
Try not
to ignore calls from operators of such stations, and do not say
to yourself “This isn’t real amateur
radio”. I have known
several amateurs for whom this is the only way they can contact fellow
amateurs, and for them it is a life-line to their hobby – take, for
example, an operator of my acquaintance in Tokyo, in a small apartment
where he
can’t erect an HF antenna, and where the VHF repeaters are constantly
jammed.
There are also a number of blind or disabled amateurs who use this
facility.
Individual stations, like anyone else on Echolink,
have
had their call signs verified by the people at www.echolink.org , so you can be
fairly
confident you are talking to a licens
