<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'> It mainly depends on how you are going to use the
system. If it is just a stand alone repeater, the RTCM is a bit of
overkill, but will work fine. I have done a couple of MSF's.</span></font><o:p></o:p></p>

<div>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'> Assuming this is just a standalone CLB repeater (the
one with the EPROM), and not a voted system, I like to keep things as simple as
possible. Program the repeater to be a "Base Station", NOT a
repeater!. Pull RX audio from the DISCRIMINATOR output of the MSF and
make sure the RTCM is set to PLFILTER=YES and DEEPPHASIS=YES.
The COR/PL Detect on a MSF is a bit trickey. You have to pull it off of a
chip and use a transistor to switch it. For TX, just use the PTT and MIC
Input. That is the simplest way. You can also feed raw TX audio
directly into the modulator from the RTCM and have the RTCM generate the <st1:Street
w:st="on"><st1:address w:st="on">TX PL</st1:address></st1:Street> if you like,
but that is a bit more complicated. I have done it, but I don't really
see much of an advantage. ALl these connections are Test Points on the
MSF, (Except the COR/PL) and that makes connection easy. ALSO, set the
squelch on the RTCM a bit high! The RTCM's squelch circuit is a bit
touchy.</span></font><o:p></o:p></p>

<div>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'> NOW, if you have a CXB (programmable MSF) it is all
basically the same except that you can program an output of the MSF for
"Valid PL Signal" and use that as the COR/PL input to the RTCM.</span></font><o:p></o:p></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>I don't use the internal controller as the repeater. I
have never been real satisfied with the audio quality of the MSF repeated
audio. Best to let the RTCM do all the work and digitally filter the DISC
audio rather than let the MSF do it! The RTCM will do all the
controlling, tail, ID and courtesy tones for you. Also, don't
forget to disable the MSF's TX Timer! </span></font><o:p></o:p></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'> Unless you are using a voting system, the URI is a
MUCH cheaper source and does everything you want for just a standalone
repeater, assuming you have a computer to go with it. I use the
Beaglebone! The URI as it will also act as the controller, filter the
DISC audio and one thing it does that the RTCM won't do is you have REMOTE
audio control! That way, after you install the repeater on a hilltop, and
you think the audio is a bit high or low, you can remotely bump it up or down
to your hearts content! The RTCM is all manual control!</span></font><o:p></o:p></p>
