All of the controllers connect to the radios pretty much the
same way. They all have the same basic connections, and
a few extras.
You start out by connecting PTT and TX audio from the controller
to your TX, then you power up the controller and see if you get
the cold-start message that every controller sends out. You have
to get that connection right before you do anything else. Once
the PTT works you adjust the master TX level pot so it sounds
clean - and don't touch anything else yet.
Then you hook up RX COR and see if you can trigger it with
your handheld. If not, find out why. Go one step at a time and
concentrate on that step until it works.
Then you hook up RX audio and see if you can repeat your
own voice.
Once you are that far you stop and go through the entire audio
level set procedure - this may involve 6 or more trimpots before
you are done with IDer levels, TT decoder levels, repeat audio
levels, etc. However it's something that only has to be done
once. Make sure that the duplex mod you did involved picking
up the RX audio from a point before the RX volume control... you
don't want your repeat level to change when you turn the local
speaker volume down to zero when you walk away from the rack.
I made a point of that in my Mitrek Interfacing writeup at
www.repeater-builder.com
Once you have a properly working basic repeater you can hook
up the extras - PL decode, PL encode, any extra gear (a weather
RX, etc).
As far as which controller.... that's like asking "Which is the best
car, Ford, Chevrolet, Honda, Toyota, Nissan"? There is too much
emotion and personal preference involved.
Personally, I thing you should look at the entire marketplace and
make your own choices based on what you want to do with the
repeater. Someone who is putting up a wide area coverage for a
2m repeater club has different needs than someone who is putting
up a 1200mhz garage repeater with remote bases on 10m, 6m, 2m,
220 and 450 so he can monitor all his favorite channels with one
1200 mhz handheld.
Ken from Arcom is a member of this list and can answer any
questions on the Arcom products.
Bob from Scom is also a member of this list and shows up both
here and on his own Scom list.
I can guarantee that if you buy from either of these two you will
be happy and a lot of folks here can answer questions.
Folks from the Link factory don't show up here at all but they have
their own list (called "RLC"). There are a number of folks on this
list that have Link controllers that can answer questions.
