Description
The synthesised TX8000 Transmitter and RX8000 Receiver can be set to one of 32 switch selectable RF
frequencies. The modules can transmit data at 10Kbps for a distance of up to 20km line of sight and 1-3km in
buildings.
The radios are ideal for general telemetry applications. The TX8000 will transmit analogue data such as FSK,
FFSK, GMSK and PWM from its analogue input or accept direct TTL digital data from its digital input. The RX8000
will receive analogue and digital data and present it to its analogue and digital outputs in the same format as it was
transmitted.
The units conform to ETSI 300-220 and ETSI 300-683.

RADIO PROPAGATION
ANTENNA
With any radio system there are a number of factors
which affect the system performance. These are:
Transmitter power output.
X603 Quarter Wave Antenna
Low cost, mobile, omni-directional, short range
approximately 2km
Height of transmitter and receiver antenna.
Length and type of coaxial feeder cable to the
antenna.
X604 Mast Mounted Dipole Antenna
Omni-directional, base station, range approximately
10km
Type and efficiency of the antenna.
Topography between transmitter and receiver.
The weather.
X605 High Gain Yagi Antenna
Directional beam of 40°, range approximately
10-20km, usually used on receivers only.

CIRCUIT CONNECTIONS
Note: On the standard RX8000, pins 4 & 5 are not present. Therefore the pins are numbered 1 to 7
RF FREQUENCY
An example of how the RF Frequency is set using the Programming Pins is shown below. The frequency band can
be factory set in the range 400.00MHz to 490.00MHz and 860.00MHz to 930.00MHz at 12.5KHz or 25KHz
spacing in bands of 1.3MHz.
