Kenwood TH-77 Extended frequency coverage and dual-band repeater

Kenwood has made this radio compatible with the new ICOM S-Series radios
from what I can tell.  It has DTSS (Dual Tone Squelch System) which means
that your radio will not break squelch until it hears a particular
sequence of three DTMF tones (ICOM has this also and they call it
Coded Squelch which also use three tones).  The TH77A also has a paging
function that works *exactly* like the ICOM paging.  You program the
radio with a personal 3 digit DTMF code and someone pages you by
transmitting YOUR 3 digit code, followed by a * character and then
their own 3 digit code.  The ICOM will start to ring to let you know
that you have been paged and display the 3 digit code of the person
that has paged you.  The TH77A will beep once and open squelch as
long as the person that paged you does not drop carrier (I prefer
the ICOM method for this part, but there is a work around that I
will mention in a bit).  One thing the TH77A does at this point is
bring up a timer so you know how long its been since you've been
paged.  Maximum time is 99 hours and 99 minutes.
