The ICOM IC-2720H is a two way cross-band repeater.  2m to 440 and 440
to 2m are the same thing.  You just set a 2m simplex frequency on one
side and a 440 frequency on the other side.  It doesn't matter which
side you use for which.  It works on any frenquency in the band.  Be
careful to pick two that are not used and two that are not harmonics
of each other.



With the frequencies set, hold "set, dupe, and low" buttons for a
couple of seconds until you get two flashing L's in the display.

Set one handheld to the 2m frequency and another to the 440 frequency.
They will talk to each other through the 2720.

Or you can set one side of the 2720 to the frequency of a local
repeater and the other side to simplex, and use it to "boost" your
handheld through to the repeater.

You can't use the ICOM IC-2720H as a repeater on one band.
