     The manual for the Alinco DJ160T is remarkably badly written, and certain
functions in particular (DTMF squelch and paging, DTMF decode) are especially
hard to understand.  I've puzzled out most of this, and have written up for my
own reference the following notes.  Some of what follows will be relevant to
other Handitalkies than the DJ 160T, especially other Alinco handitalkies such
 as
the DJ 460T and DJ 560T.
 
     Introduction:  Keys on the Alinco are given here in brackets [].  The
function key is given as [f].
 
     DTMF functions:
 
     There are three broad categories of DTMF functions supported by the DJ160T.
These are DTMF squelch, DTMF paging, and DTMF decoding.  DTMF paging is further
broken down into DTMF group paging and DTMF personal paging.
 
         DSQ  overview
     To use the DTMF squelch and page functions, you must first SET your DTMF
code(s). This is done using the [f] [DSQ set] button combination.  Now you can
enter FIVE digits that determine DSQ functions.  They are displayed as a group
 of
three digits, a period, a single digit, another period, and a final fifth digit.
The FIRST THREE DIGITS are used for DSQ squelch and for DSQ group paging.  This
is the three digit code required to break a DSQ squelch, or the three digit
"group page code" that, when followed by a *, will cause the handitalki to beep
when the handitalkie is placed in G DSQ or GP DSQ modes.
 
     These three digits are really the most important ones!  The other two
 digits
are part of personal paging / personal ID options that are complex of less
importance in day to day use.  However, I do explain their functions.
 
     The fourth digit is the single digit used in combination with the group 
code
to page a particular person in a group.  Note that some newer handitalkies
provide for a three digit personal code.   This may be why the Alinco uses two
*'s as part of its group page format, where the *'s are dummies for the missing
two digits that other radio DTMF systems use in their personal codes.  The 
Alinco
DJ160T has provisions to transmit and receive any three digit personal code
("Additional Feature of DSQ Function" on page 27 of the manual), but 
implementing
that provision is hideously complex and probably not worth bothering with.
