<div>Got a problem with one of my repeater.</div>
<div> </div>
<div>I live in Montreal QC, and as many of you know we are bless with a small
mountain right in the middle of the city. (Mount-Royal) While if you have the
blessing of having a repeater on top of it, the coverage is marvellous. (but I
am not blessed at all!!!) </div>
<div> </div>
<div>So I have nice repeater to cover the north, east, and south of the city,
but the damn mountain prevent me from covering properly the west part of the
city. </div>
<div> </div>
<div>So I was looking at the rtcm to make a multicast/voter system on the other
side of the mountain. </div>
<div> </div>
<div>I have a MSF5000 UHF at the main repeater site, would I be able to use that
with the rtcm and I can have a TKR-820 as the remote repeater would I be able to
use it too? Or I also have a Desktrac that used to be the UHF repeater before
the MSF500 came along..</div>
<div> </div>
<div>What would I need to do make sure that its all stable? I think I would need
at least 2 rtcm, But I would loose the dsp decoding of ctcss and squelch? </div>
<div> </div>
<div>Lots of question..</div>
