Standard C828M - Features of C828 M

1. Features of C828M
We know that lighter and smaller high-performance equipment creates new appli-
cation, and this is quite true of C828M. Such features and many others of this
Model as mentioned below will enable all of you-from beginners to veterans-to enjoy
a broader scope of the usages.
1. small Size and Light Weight:
This new FM transceiver, smaller in volume than a half size of the comparable
products of this Company and as light as 0.96 kg, has succeeded in hnding its
Installation space for mobile Station use at vehicle driver's seat area instead of
assistant driver's which has been exclusively used for this purpose in the past,
ushered in the debut of a new type mounting metal bracket.
2. Push-In/Push-Out Bracket:
This metal bracket has simplified the attaching and detaching processes of
C828M on a Single motion basis. For attaching, just snap your transceiver into
the bracket. The reve/'se consequence can be obtained by simply snapping it off
toward you.
The bracket with the transceiver off therefrom is an evenly faced metal, which
therefore prevents rattling causable during the vehicle Operation and also protects
your feet against a possible hazard from a sharp projection. Such attaching and
detaching processes do not require you to put in your hands on the sides of the
rig. Thus, the attaching process brings the sides of the rig into a dose contact
with their corresponding parts. The rig's occupancy of small space serves for
the efficient employment of the limited interior room of the car. ^ '
3. Single Crystal System Common to Transmission and Reception:
The adoption of the Single crystal system, in which one crystal is used for both
transmission and reception of Signals, has opened the way to an economical In
stallation of additional Channels and the very expedient experiment or Operation
in Joint use of multifarious external oscillators.
4. One Action Repeater Changeover System:
The transceiver has 3 built-in offset oscillators including SIMPLEX. This fea-
ture together with the füll advantages of the single crystal system permits change
over to the repeater Channel with a fi nger action of switch on the front panel.
5. Call switch for Tone Burst Signal Transmission:
C828M incorporates tone burst device (CTN-5). By pressing the call switcb
(momentary switch) for Operation of repeater Channel, a high power tone burst
Signal is transmitted, thus assuring stabilized Operation of repeater.
6. Hi-Low Power Changeover:
By setting the function switch on the front panel from " high " to " low " power
Position, the antenna Output is reduced from lOW to IW with resultant decrease
of power consumption. This prevents radio interference and other disturbances
during local QSO, providing smooth and efficient Operation.
7. Remote Control System for External Oscillator Changeover:
Connection of external oscillator to the transceiver can be made simply by flipp-
ing the evternal oscillator switch on the microphone.
8. Professional-minded Circuit Design:
FET's, Silicon transistors and diodes are abundantly used in the circuitry de-
