Hello Eric and group,
I have an old 386 I use for programming. I went to boot it up one

I bought a msf 5000 cxb vhf station for my club to build a repeater.
this unit was rack mounted along with several public safety repeaters

The only issue might be getting the receiver up to the 440-450
range and maybe reduced output from the high power 110w PAs.
If you can get them cheap they are well worth using. You
can also trade them with us here in the US for mid range
receivers as we use the 420 band for linking.
Hi Jessie,
What I call the Canadian 40 watt PA is pretty much a Mitrek Mobile
50 watt board in the same 110 watt chassis. There is no easy way
to tell the difference from the outside unless you know the model
numbers.
The Canadian PA works mucho fine as built. Most will do at or above

First of all, we need to know exactly which model and variant of MTR2000
station you have. The model number T5766A or T5644A that appears on the

power.
Remove the black plastic front cover from the station, and carefully

Steve,
I have to wonder why anyone would want to hook up an external controller to
an R1225 radio, when it has a very capable controller built-in. And that
may be at the heart of your problem. I suspect that both the internal and
the external controller are trying to do the same thing at the
Hi Eric,
The reason for using an external controller is I have two other repeaters (2,
220) on the site that i am interfacing with. The PL level being transmitted is
750 Hz. Under normal operation using a external controller, PL is not passed
through, but is re-incoded by the transmitter. The

This is an easy one, but I need to see what you have programmed in order to
suggest any changes. Please send me the codeplug file (it ends in .cpg)

I don't know of anyone that does this. Yet it is in the rules.
I think the legal out here is that automatic control relieves the need
for remote control, with only the latter requiring the heartbeat timer.

I think it's an interpretation of how you define failure of the control
link. You could use an active low COS and if the repeater controller
sees three minutes of continuous low, it assumes the control has failed.
But, that is a discussion for another day - or another list.
