The magic repeater can be activated on several band now!
You can now find us on VHF 145.170 MHz. - offset
amd a 100.0 Pl tone.
On UHF you can access the system from UHF 443.050 MHz. +offset.
We also have 6 meters up on line. 53.470 MHz with a - offset, (Temporarily
down for repairs)
Currently the Magic repeater system is going through several changes
and we hope to have another system near Foresten, Mn. on 146.745
MHz, N0GOI repeater. At this time we have three receive sites up and running. The
receive sites are located in Woodbury,
MN. KF0ZM, St. Paul, MN. KA0JLB, George N0SBU in Hugo, MN. One of the
current changes to the Magic repeater system is the installation of a
new voter and two new reciever sights. One in Brooklyn Center,and one in
Bloomington. We hope this will solve a lot of the sight hopping we were
having. The sites use a UHF link to the voter for those of you who didn't
already know. Note!
While listening to the repeater I often hear the first time amateur
asking questions like, how come I can hear the 145.170 mach. on 443.05 or
what do you mean I'm going through the St. Paul Park site? If your one of
the newbie's to the magic repeater system or any VHF or UHF system your not
alone. With all the new no-code techs entering the VHF an UHF bands I hear
these questions every day. What ever your current license maybe or maybe
your even a avid scanner listener, let me see if I can fill in some of these
blanks for you. For an example if your in the Woodbury MN. area and using
145.170 MHz machine with a negative offset and a Pl tone of 100.0 your listening to the out put of
the transmitter which is located in St. Paul, MN. When you transmit with
the negative offset your transmitting on 144.570 MHz and may very well be
getting into several receive sites. WHAT IS A RECEIVE SITE? A receive site
and we have a few, is just what it sounds like. In short its another repeater
that receives your signal as you transmit and then retransmits the signal. In
the case of the magic system and the example above your signal is received
and retransmitted on what we call a UHF LINK to the main transmitter in
St. Paul. At the St. Paul main site there is of course a UHF receiver that
grabs the signal and retransmits the signal out on 145.170 MHz. Now that
is a simple explanation of what is going on when you transmit. There are
a few other thing to keep in mind that are going on behind the scenes. #1
the main site may also be transmitting your signal on another band such as
UHF and our 443.050 machine. #2 You might be into several sites at the
same time. That's where the voter comes into play.
It receives your signal from the different sites and determines which sight
your getting into best by comparing each signal from each sight and the
noise levels coming from each of the sites. The voter then says "hay I'm
getting a better signal from the Woodbury site than I am from the St. Paul sight so lets use the Woodbury signal" and then passes that signal
through the system.
