VOLUME (OPTIONAL‐T13)
Rotate the volume control clockwise to adjust the volume control
for a comfortable listening level. If no sound is heard, temporarily
un-mute the radio by briefly rotating the Squelch Control full anticlockwise. You can adjust the volume by listening to the receiver's
background noise.
When finished, return squelch setting. (See section on setting
Squelch.)
CHANNEL SELECTING (OPTIONAL‐T14)
Push to select the memory channel number for the selected
readout.
The channel display will Rotate and select the higher channel
when the up button is pressed.
By pressing the down button the Channel display will rotate to
display the lower channel selected. The selected channel is
displayed.
To enable the Repeater Function (TTR) the operating channel
will required to be programmed as a repeater and User Dip
Switch2-4 enable on motherboard.
Receiving A Call
With the MX800 powered ‘ON’ the front panel Green led is lit.
•
Set the audio and squelch levels as per SQUELCH
and VOLUME section.
•
Select the desired receiving channel as per Channel
selecting section.
•
When receiving a signal the ‘Amber RX LED‘ indicator
lights green when the squelch is open, and audio is
emitted from the speaker.
•
Listen for your call sign when you hear activity, and
reply promptly by identifying yourself if called. (For
example: Base receiving).

SQUELCH (Front panel option‐T13)
The squelch is used to eliminate any annoying background noise
when there are no signals present.
This control is located on the main controller motherboard (RV6)
an optional model can have it fitted on the front panel. A
technicians tuning tool will be required to adjust this setting.
(Factory set for 8dB SINAD)
When no signal is received, rotate the Squelch control (SQL) fully
counterclockwise first, and then rotate SQL clockwise to the point
that the noise just disappears. This will provide optimum Squelch
performance.
When the Squelch is Open, the receiver's background noise can
be heard and 'Amber RX LED' is lit on the front panel display.
When the Squelch is closed, the receiver remains quiet when there
are no signals present but any incoming signals will override the
Squelch and be heard in the speaker.
NOTE: If an incoming signal is very weak and is close to the
minimum squelch level, it may become broken or “chopped” by the
squelch action. To prevent this, simply open the squelch to allow
the signal to be heard clearly. Alternatively, you can reduce the
squelch sensitivity as described above.
When CTCSS is enabled the channel remains quiet until someone
transmits using the same tone, and the 'Green Tone LED' lamp
will be lit. When the transmission ends, the channel becomes quiet
again. By using different tones, several groups of people can share
the same channel without disturbing each other.
ACCESSORY SWITCH (Depends on Options)
With the MX800 powered ‘ON’ the front panel Green led is lit.
•
Select the desired channel, as previously described.
•
If the ‘Amber RX LED' indicator is on, the channel is
busy and you must wait until it is free, before
proceeding. If you attempt to transmit anyway, the
other party may not receive your transmitted signal.
•
Lift the microphone off-hook and listen to check that
no one else is using the channel. You may also have
to press the Monitor Key on the desktop Microphone
or the Accessory button on the radio briefly, depending
on the microphone used and the options programmed
to your radio.
•
When using the Hand-Held microphone, Hold it about
5cm from your mouth and press the Press-To-Talk
(PTT) key, located on the side of the microphone (see
Figure 3-1). Speak clearly into the microphone at your
normal voice level, identifying yourself by your call
sign, and the person you wish to contact. (For
example: Base to Mobile 2.).
•
The ‘Red RX LED’ indicator lights while transmitting.
•
Release the PTT key when you have finished talking.

Transmit Timer
Your MX800 is fitted with a preprogrammed timer to limit the
maximum length of transmissions.
When the time limit is reached, the transmission is terminated.
(Subject to Radio Firmware)
The Accessory button is a programmable momentary switch.
Which is assigned a function in software programming. (Subject to
Radios firmware)
See Dealer for application notes for further information on this
feature.
REPEATER MODE
In repeater mode, the received signal is processed and retransmits
at a different frequency.
Repeaters are usually located on hills, mountains or tall buildings.
The increased elevation greatly improves the range of the repeater
beyond that of a normal base or Mobile. This means that the
repeaters are able to receive and retransmit signals to radios that
would otherwise be out of range of each other.

Unpacking
SWR
The MX800 Radio is securely packed for transport with special foam
packers within a pasteboard container. Before unpacking the MX800
radio, please inspect the MX800 & packaging for signs of damage and
report any damage to your MX800 distributor.
Upon unpacking of the MX800 radio, please ensure that all items
shipped were received, report any missing items to your MX800
distributor. All ports on the rear of the radio should be carefully examined
to ensure that packaging has not become wedged inside them. It is very
important to examine the fan, as operation of the radio will be affected if
any packaging or shipping damage causes the fan to stop working.
Each antenna is tuned for a specified frequency range and SWR
may be increased if used out-of-range.
When the SWR is higher than approx. 3.0:1, the transceiver’s
power drops to protect the Power Amplifiers final transistor. Low
SWR allows full power for transmitting. The MX800 has a
software diagnostic SWR meter to monitor the Antenna SWR
continuously.
Installing the Base Station System
The design of the MX800 allows it to be installed in a 19inch rack.
If you intend to install the radio in an equipment rack consult the
supplier’s instructions for your system.
Ensure that it is in a secure, dry location with sufficient air space around
it to allow for adequate ventilation. It is recommended that the chassis be
earthed.
Power Supply
The MX800 requires an external 13VDC power supply. Spectra
Engineering manufactures an Automatic Backup Battery Change Over
System and single power supplies. The built-in backup system supports
automatic switching to an external power DC battery supply if the AC
power supply fails.
Make sure the [POWER] switch on the back of the PSU is turned OFF
when connecting an AC power cable and also when connecting the DC
power cable for a backup battery (Refer to the Mains ratings label on the
rear of the PSU module)
Note.
The MX800 will draw approximately 7 to 10Amps 50W (band dependent)
& 15Amp 100W opt. on transmit and when external power supply \
batteries are used, the gauge of the DC cable fitted to the 12V supply
connector should be adequate to ensure less than 0.5V volt drop at this
current.
If external batteries are used and are non-sealed Lead-acid batteries
type, placement should be at least 4 m away from the repeater.
No reverse polarity protection.
Be sure both the positive (red) and negative (black) terminals are
correctly connected and an inline 15Amp fuse for 50W or 20Amp for
100W opt. should be fitted on the Positive wire. See example in picture
below (Not include)
Inline Fuse
15Amp Fuse
Holder
Fuse Link
Antenna
In radio communications, the antenna is critical importance, effecting the
output power and sensitivity.
The antenna and coax cable should be the 50ohm type, and have a
Voltage Standing Wave Ratio (VSWR) of 1.5:1 or better.
CAUTION: Protect repeater from lightning by using a lightning arrestor.
NOTE: There are many publications covering antennas and their
installation. Consult with your local dealer for more information and
recommendations.
Duplexer
The MX800 with optional external duplexer kit provides mounting
for a number of different manufactures mobile duplexers.
A duplexer is required when only one antenna is used for both
transmitting and receiving. Select a duplexer according to the
transmitting and receiving frequencies.
See Dealer for further information on this feature
Software Programming
The MX800 can operate in a number of different modes. The
primary alternatives are full duplex, which is the default mode,
repeater and simplex. Using MXtools programming utility the
MX800 can be programmed to suit individual system needs.
This is done thought the configuration menu system, with a
Personal Computer (PC) Widows XP and a RS232 programming
cable.
MXTOOLS is a Base Station Programming Utility specifically
designed to use in conjunction with the Spectra MX800 Base
Station. MXTOOLS provides easy viewing and setup of the
parameters within the MX800 Base Station. MXTOOLS is used
for three main purposes:
• Channel programming and viewing
• Configuration setup
• Viewing and radio diagnostics.
MXTOOLS is a powerful utility giving comprehensive control
over the information within the radio while maintaining an easy to
use user interface simplifying the setup of your MX800 Base
Station.
MXTOOLSRD is an application in which you can diagnose and
