TM732A.1
The controls have the typical legends borrowed from the 241 and
the 741 series. It is disappointing to note that the key
legends are not illuminated for nighttime use.
There are two speaker jacks on the rear, one for each band with
one that can output both bands. The antenna connectors are
typical Kenwood pigtail style with no built-in duplexer. The
same mounting hardware and bracket is used as with the TM-241.
A look under the covers reveals an impressive dual-hollowed die
cast aluminum case which looks like it could withstand an air
drop. The The upper hollow contains the VHF transceiver with
the UHF in the lower portion. The speaker is a nice size (about
2") and sits in the upper (VHF) portion of the case. The base
unit includes a third circuit board which is attached to the
front and is a "mother board" of sorts which contains the base
unit MPU and interface connectors. The only other circuit board
is the one found in the remote control head unit.
The overall integration of the unit is impressive. My first
impression in looking inside was that it was mostly empty.
That's because the surface mounted components are so small and
the integration so high that there are only a few visible
building blocks present. There are, for example, no wires
inside this box. Well, to be accurate, there are the two wires
which feed the speaker. That's it. The rest of the connections
are all made via printed circuit paths. There is one short,
small, green wire in the control head, which when clipped
enables extended receive capabilities (see below).
There are a couple of small adjustable pots inside, and these
are the smallest that I've ever seen. They, like everything
else, are surface mount types. I would guess their size to be
on the order of 3mm square! If I were to try and adjust them,
I'd probably use the eraser end of a pencil. These pots adjust
the high and low power output settings as well as the max
deviation.
The unit comes DTMF ready, which means that a DTMF decoder board
is included. This gives it remote control ability, DTMF squelch
and paging, and a 10 number autodialer. The only internal option
offered is the TSU-7 CTCSS (PL decode) board ($50).
