<div><font size="2" face="Arial">Hi,</font></div>
<div><font size="2" face="Arial">My local repeater uses 131.8 for a PL
tone.</font></div>
<div><font size="2" face="Arial">I at one point had 88.5 in one place and 131.8 in
the other.</font></div>
<div><font size="2" face="Arial">So I changed both to 131.8, and it seems that it
should still work, but it isn't keying the repeater.</font></div>
<div><font size="2" face="Arial">I'm guessing the R in r-tone is for repeater, and
the C in C-tone is CTCSS?</font></div>
<div><font size="2" face="Arial">Anyway, which one of these is the repeater wanting
to hear to open up?</font></div>
<div><font size="2" face="Arial">Thanks.</font></div>
