1 OPERATING INSTRUCTIONS
WARNING
Changes or modifications not expressly approved by
RF Technology could void your authority to operate this
equipment. Specifications may vary from those given in
this document in accordance with requirements of local
authorities. RF Technology equipment is subject to
continual improvement and RF Technology reserves the
right to change performance and specification without
further notice.
1Operating Instructions
1.1 Front Panel Controls and Indicators
1.1.1 PTT
A front-panel push-to-talk (PTT) button is provided to facilitate bench and field tests and
adjustments. The button is a momentary action type. When keyed, audio from the line input
is disabled so that a carrier with sub-tone is transmitted. The front-panel microphone input is
not enabled in this mode, but it is enabled when the PTT line on that socket is pulled to
ground.
1.1.2 Line
The LINE trimpot is accessible by means of a small screwdriver from the front panel of the
module. It is used to set the correct sensitivity of the line and direct audio inputs. It is
factory preset to give 60% of rated deviation with an input of 0dBm (1mW on 600
Ω
equivalent to 775mV RMS or about 2.2V peak-to-peak) at 1kHz. The nominal 60% deviation
level may be adjusted by measuring between pins 6 and 1 on the test socket, and adjusting the
pot. By this means an input sensitivity from approximately -30dBm to +10dBm may be
established.
An internal jumper provides a coarse adjustment step of 20dB. Between the jumper and the
trimpot, a wide range of input levels may be accommodated.
1.1.3 POWER LED
The PWR LED shows that the dc supply is connected to the receiver.
1.1.4 TX LED
The TX LED illuminates when the transmitter is keyed. It will not illuminate (and an Alarm
cadence will be shown) if the synthesizer becomes unlocked, or the output amplifier supply is
interrupted by the microprocessor.

2.8 JP9/10/11: dc Loop Configuration
Dc loop current on the audio pair is normally sourced externally. The Eclipse exciters loop
the current through an opto-isolator. When the current flows the exciter keys up.
An alternative arrangement is possible. The exciters can source the current and an external
device can provide the dc loop.
These three jumpers select the appropriate mode.

2.9 JP16: Direct Digital Input (Rev 4 or Higher)
Some trunking controllers have digital encoding schemes which operate to very low
frequencies. The elliptical filter, used as a 250Hz low pass filter in the tone section, can
___________________________________________________________________________
RF Technology T800 Page 9
2 TRANSMITTER INTERNAL JUMPER OPTIONS 2.10 JP17: Bypass Low Pass Filter
cause excessive pulse edge distortion of the trunking controller’s digital signals. In such
circumstances, JP16 allows a user to bypass the low and high pass filters in the
tone input
section. See also 2.12 - JP22: If direct tone input is selected, then JP22 should be removed
(open)
Condition Position
Normal Tone Input 1-2*
Direct Tone Input 2-3
2.10 JP17: Bypass Low Pass Filter (Rev 4 or higher)
Some trunking controllers have digital encoding schemes that require the low pass filter in the
tone input section to be bypassed. JP17 allows this. Normally JP17 is open circuit. Placing
a link across it will bypass the low pass filter.
In conjunction with this change, it sometimes may be necessary, depending on the type of
trunking controller used, to add a 100K resistor in the place reserved for R157.
2.11 JP19: Alarm Output (Rev 4 or higher)
The main audio transformer (T1), is connected to the Line IP1 and Line IP4 pins on P3.
These two pins constitute the main audio input for the exciter. The centre taps of the audio
transformer, though, are brought out on Line IP2, and Line IP3. These can be used as
alternate audio pins for larger signals, or to directly access the dc loop sense circuitry. JP19
allows an alternate use for Line IP2 (pin 7 of P3). In the alternate position for JP19, the
ALARM signal (the signal that drives the ALARM LED itself) is connected to pin 7 of P3.
The ALARM signal when asserted is low active; when unasserted, it pulls high to +9.4V
through an LED and a 680 ohm resistor.
Condition Position
P3, pin 7 connects to center tap of transformer T1 1-2*
P3, pin 7 connects to ALARM signal 2-3
2.12 JP22: Use Tone- as a Direct Digital Input (Rev 4 or higher)
JP22 is normally shunted with a jumper, which connects Tone- on P3 (pin 18), as the negative leg of the
Tone input pair. Removing this jumper disconnects Tone- from this path and allows the use of the
Tone- pin to be used as a direct digital input. See also 2.9 - JP16: If this jumper is removed, then JP16
should be in the alternative position (Direct Tone Input).
2.13 JP23: Connection of DMTX Board (Rev 4 or higher)
When a DMTX board is connected to an exciter, there is provision for digital or audio modulation of the
reference osciallator and the VCO. The digital signal is input via the DB9 rear connector and the audio
input signal is via the Line inputs on the standard DB25 rear panel connector.

Channel and Tone Frequency Programming
Channel and tone frequency programming is most easily accomplished with RF Technology
TecHelp software or the Service Monitor 2000 software. This software can be run on an IBM
compatible PC and provides a number of additional useful facilities. DOS and 32-bit versions
are available.
TecHelp allows setting of the adaptive noise squelch threshold, provides a simple means of
calibrating the forward and reverse power detectors, setting the power alarm preset levels, and
enabling transmitter hang time and timeout time limits. TecHelp can be supplied by your
dealer, distributor or by contacting RF Technology directly.

5 CIRCUIT DESCRIPTION 5.1 VCO Section
5Circuit Description
The following descriptions should be read as an aid to understanding the block and schematic
diagrams given in the appendix of this manual.
5.1 VCO Section
The Voltage Controlled Oscillator uses a bipolar junction FET Q19
which oscillates at the
required transmitter output frequency. Varactor diodes D25 and D26 are used by the PLL
circuit to keep the oscillator on the desired frequency. A second varactor diode D3 is used to
frequency
modulate the VCO. Transistor Q20 is used as an active filter to reduce the noise
on the oscillator supply voltage.
The VCO is keyed ON by the microcontroller through Q10. It is keyed ON when any of the
PTT inputs are active and OFF at all other times.
The VCO output is amplified and buffered by monolithic amplifiers MA2 and MA3 before
being fed to the PLL IC U6.
Amplifiers MA1, MA4 and MA5 increase the VCO output to approximately 10 mW to drive
the power amplifier. MA1 is not switched on until the PLL has locked and had time to settle.
This prevents any momentary off channel transmission when the transmitter is keyed.
5.2 PLL Section
The frequency reference for the synthesiser is a crystal oscillator using transistors Q26 and
Q27 and crystal Y3. The temperature stability is better than 5 ppm and it can be synchronised
to an external reference for improved stability. External reference option board 11/9119 is
required when using an external reference.
A positive temperature coefficient thermistor, XH1, is used in versions intended for operation
down to -30 degrees Celsius. The thermistor heats the crystal's case to maintain its
temperature above -10 degrees thus extending the oscillator stability of 5 ppm down to -30
degrees ambient.
Varactor diodes D27-30
are used to frequency modulate the oscillator. The processed transmit
audio signal from U7b varies the diodes bias voltage to modulate the reference frequency.
This extends the modulation capability down to a few Hz for sub-audible tones and digital
squelch codes. A
two point modulation scheme is used with the audio also being fed to the
VCO to modulate the higher audio frequencies.
The 12.8 MHz output of Q27 is amplified by Q28 and Q29 to drive the reference input of the
PLL synthesiser IC U6. This IC is a single chip synthesiser which includes a 1.1 GHz pre-
scaler, programmable divider, reference divider and phase/frequency detector. The frequency
data for U6 is supplied via a serial data link by the microcontroller.
___________________________________________________________________________
RF Technology T800 Page 14
5.3 Power Amplifier 5 CIRCUIT DESCRIPTION
The phase detector output signals of U6 are used to control two switched current sources. The
output of the positive and negative sources Q3 and Q6, produce the tuning voltage which is
smoothed by the loop filter components to bias the V.C.O. varactor diode D3.
5.3 Power Amplifier
The 10 mW output from the main board connects to the power amplifier board through a short
miniature 50Ω coaxial cable.
Q2 on the power amplifier board increases the signal to approximately200mW.
The bias of
Q2 is controlled by Q1 and the power leveling circuitry to adjust the drive to the output
module U2.
U2 increases the power from the driver to 30 watts before it is fed to the directional coupler,
low pass filter and output connector. The directional coupler detects the forward and reverse
power components and provides proportional dc voltages which are amplified by U1a and
U1b.
The forward power voltage from U1a and U1b are compared to the present DC reference
voltage from RV1.
The difference is amplified by U1c, Q3 and Q4. The resulting control
voltage supplies Q2 through R10, R12 and completes the power levelling control loop.
5.4 Temperature Protection
Thermistor RT1 on the power amplifier board is used to sense the case temperature of the
output module U2. If the case temperature rises above 90 degrees C, the voltage across RT1
will increase and transistor Q5 will be turned on. This reduces the dc reference voltage to the
power regulator which inturn reduces the outpower by 6-10dB.
5.5 600Ω Line Input
The 600Ω balanced line input connects to line isolation transformer T1. T1 has two 150Ω
primary windings which are normally connected in series for 600Ω
lines. The dual primary
windings can be used to provide DC loop PTT signaling or a 2/4 wire hybrid connection. All
four leads are available at the rear panel system connector.
The secondary of T1 can be terminated with an internal 600Ω
load through JP5 or left un-
terminated in high impedance applications.
5.6 Direct Coupled Audio Input
A high impedance (10k
Ω) direct AC coupled input is available at the system connector. The
direct coupled input connects to U9a which is configured as a unity gain bridge amplifier.
The bridge configuration allows audio signal inversion by interchanging the positive and
negative inputs and minimizes ground loop problems. Both inputs should be connected, with
one lead going to the source output pin and the other connected to the source audio ground.
___________________________________________________________________________
RF Technology T800 Page 15
5 CIRCUIT DESCRIPTION 5.7 Local Microphone Input
5.7 Local Microphone Input
The local microphone input is provided for use with a
standard low impedance dynamic
microphone. The microphone output is amplified by U9a before connecting to analogue
switch U10a. U10b inverts the local microphone PTT input to switch U10a ON when the
microphone PTT button is pressed. U10a is OFF at all other times.
The local microphone audio has priority over the other inputs. Activation of the local
microphone PTT input switches OFF the audio from the line or direct inputs through D16 and
U10c
5.8 CTCSS and Tone Filter
The CTCSS encoder module H1, under control of the main microprocessor U13, can encode
all 38 EIA tones and (on some models) additional commonly-used tones.
The tone output of H1 connects to jumper JP8
which is used to select either H1 or an external
tone source. The selected source is coupled to U9c which is a balanced input unity gain
amplifier. The buffered tone from U9c is fed to 300 Hz low pass filter U7c.
On Rev 4 or later revisions, the low pass filter can be by passed by inserting a jumper onto
JP17.
RV3, the tone deviation trimmer, is used to adjust the level of the tone from U7c before it is
combined with the voice audio signal in the summing amplifier U7a.
Back to back diodes D4 and D5 limit the maximum tone signal amplitude to prevent
excessive tone deviation when external tone sources are used.
The subtone amplifier, filter and limiter can be bypassed on Rev 4 or later exciters by
removing the link from JP22 and moving the link in JP16 to the alternate position.
5.9 Audio Signal Processing
Jumper JP4 selects either the line or direct input source. The selected source is then
connected to JP6. JP6 can be removed to provide 20 dB attenuation when the input level is
above 10 dBm to expand the useful range of the line level trimmer RV4. The wiper of RV4 is
coupled to the input of the input amplifier U9d. U9d provides a voltage gain of ten before
connecting to the input of analogue switch U10c.
The outputs of U10a and U10c are connected to the frequency response shaping networks
C52, R133 (for 750
µs pre-emphasis) and C61, R55 (for flat response). JP7 selects the pre-
emphasized or flat response.
The audio signal is further amplified 100 times by U7d. U7d also provides the symmetrical
clipping required
to limit the maximum deviation. The output level from U7d is adjusted by
RV1, the deviation adjustment, before being combined with the tone audio signal in the
summing amplifier U7a.
___________________________________________________________________________
RF Technology T800 Page 16
5.10 PTT and DC Remote Control 5 CIRCUIT DESCRIPTION
The composite audio from U7a is fed through the 3Khz low pass filter U7b. When the links
on JP23 are in their default state, the filtered audio is coupled to the TCXO voltage tuning
input and the modulation balance trimmer RV2. RV2, R99 and R98 attenuate the modulation
signal before applying it to the VCO via varactor D3.
When DMTX board option is required, Jumper JP23 allows the audio paths to be re-routed.
The DMTX board provides for an external digital modulation input signal.
When the two
links on JP23 are positioned in the middle of the 6 pin header, the audio from the exciter is
passed to the DMTX board via pin 5 of JP15, where the signal is conditioned and then
returned from the DMTX board via pin 2 of JP15, and passed to the two modulation points.
RV2 adjusts level of the audio used to modulate the VCO. This primarily effects the deviation
of audio frequencies above 500 Hz. RV2 is used to balance the high and low frequency
deviation to obtain a flat frequency response relative to the desired characteristic.
5.10 PTT and DC Remote Control
Two main PTT inputs are provided. The first, a direct logic level input, is connected to pin 3
of the system connector. The transmitter can be keyed by applying
a logic low or ground on
pin 3. Pin 3 connects to the PTT logic and microprocessor through D10.
DC current loop control can be used for remote PTT operation.
The current loop can be
configured by JP9, JP10 and JP11 for use with either a remote free switch or a remote
switched source.
Opto-isolator ISO1 is used to isolate the loop current signal from the transmitter PTT logic.
The loop current passes through the input of ISO1 and the output of ISO1 connects to the PTT
logic.
A bridge consisting of diodes D6, D8, D9 and D14 ensures correct operation regardless of the
current polarity. Q17 limits the current and D7 limits the voltage input of ISO1. Any low
voltage current source capable of providing 2mA at 4V or switching circuit with less than
4.8k¿ loop resistance can be used to switch the DC loop.
The test PTT button on the front panel and the local microphone PTT button will also key the
transmitter. Both of these also mute the line audio input. The microphone line also enables
that audio input.
A DMTX board can also cause the exciter to key up. When TX (or TTL_TX) signal is
received by the DMTX board, it pulls pin 6 of JP15 low, which in turn asserts the
PTT_WIRE-OR signal, causing the microprocessor (U13) to key the exciter up.
5.11 Microprocessor Controller
The microprocessor controller circuit uses a single-chip eight bit processor and several
support chips. The processor U13 includes non-volatile EE memory for channel frequencies,
tones, and other information. It also has an asynchronous serial port, a synchronous serial
port and an eight bit analogue to digital converter.

5 CIRCUIT DESCRIPTION 5.12 Voltage Regulator
The program is stored in U5, a CMOS EPROM. U4 is an address latch for the low order
address bits. U2 is used to read the channel select lines onto the data bus. U11 is an address
decoder for U5 and U2. U3 is a supervisory chip which keeps the processor reset unless the
+5 Volt supply is within operating limits. U1 translates the asynchronous serial port data to
standard RS232 levels.
The analogue to digital converter is used to measure the forward and reverse power, tuning
voltage and dc supply voltage.
If the processor detects that the PTT_WIRE_OR signal is asserted low, it will
attempts to key
the exciter up. If will first attempt to key the VCO through Q10, and if the LD pin goes high,
it will switch the 9.2 Volt transmit line through Q14 and Q16.
asserting Q16 has the effect of
also asserting the yellow Tx LED (D12) on the front panel, enabling the local 25W power
amplifier, and causing the T/R Relay output to be pulled low. D24 is
30 volt zener which
protects Q25 from both excessive voltages or reverse voltages.
Should there be a problem with either the tuning volts, or the battery voltage, the VCO
locking, the forward power, or the reverse power, the microprocessor will assert the ALARM
LED, through Q1. Depending on the setting of Jumper JP19, the ALARM signal can be
brought out on pin 7 of P3.
5.12 Voltage Regulator
The
dc input voltage is regulated down to 9.4 Vdc by a discrete regulator circuit. The series
pass transistor Q23 is driven by error amplifiers Q8 and Q18. Q9 is used to start up the
regulator and once the circuit turns on, it plays no further part in the operation.
The +5 Volt supply for the logic circuits is provided by an integrated circuit regulator U14
which is run from the regulated 9.4 Volt supply.
Jumper JP18 is not normally fitted to the board, and is bridged with a 12mil track on the
component side of the board. It is provided so that the 9.4V load can be isolated from the
supply by the service department to aid in fault finding.
Jumpers JP20 and JP21 are also not normally fitted on the board, and are usually bridged with
a 12mil track on the component side. They allow U14 to be isolated from its input, or its
output or both.
6Field Alignment Procedure
The procedures given below may be used to align the transmitter in the field. Normally,
alignment is only required when changing operating frequencies, or after component
replacement.
The procedures below do not constitute an exhaustive test or a complete alignment of the
module, but if successfully carried out are adequate in most circumstances.

7SPECIFICATIONS 7.1 Overall Description
7SPECIFICATIONS
7.1 Overall Description
The transmitter is a frequency synthesized, narrow band FM unit, normally used to drive a
50
watt amplifier. It can also be used alone in lower power applications.
Various models allow 2-25W of output power to be set across a number of UHF frequency
bands. All necessary control and 600Ω line interface circuitry is included.
7.1.1 Channel Capacity
Although most applications are single channel, it can be programmed for up to 100 channels,
numbered 0 - 99. This is to provide the capability of programming all channels into all of the
transmitters used at a given site. Where this facility is used in conjunction with
channel-
setting in the rack, exciter modules may be “hot-jockeyed” or used interchangeably. This can
be convenient in maintenance situations.
7.1.2 CTCSS
Full EIA sub-tone capability is built into the modules. The CTCSS tone can be programmed
for each channel. This means that each channel number can represent a unique RF and tone
frequency combination.
7.1.3 Channel Programming
The channel information is stored in non-volatile memory and can be programmed via the
front panel test connector using a PC and RF Technology software.
7.1.4 Channel Selection
Channel selection is by eight
channel select lines. These are available through the rear panel
connector. Internal presetting is also possible. The default (open-circuit) state is to select
channel 00.
A BCD active high code applied to the lines selects the required channel. This can be
supplied by pre-wiring the rack connector so that each rack position is dedicated to a fixed
channel. Alternatively, thumb-wheel switch panels are available.
7.1.5. Microprocessor
A microprocessor is used to control the synthesizer, tone squelch,
PTT function and facilitate
channel frequency programming. With the standard software, RF Technology modules also
provide fault monitoring and reporting.

connections. The circuit can be connected to operate through the 600Ω
line or through a
separate isolated pair.
7.4.22 Programmable No-Tone Period
A No-Tone period can be appended to the end of each transmission to aid in eliminating
squelch tail noise which may be heard in mobiles with slow turn off decoders. The No-Tone
period can be set from 0--5 seconds in 0.1 second increments. The No Tone period operates
in addition to the reverse phase burst at the end of each transmission.3
7.4.23 Firmware Timers
The controller firmware includes some programmable timer functions.
Repeater Hang Time - A short delay or ``Hang Time''
can be programmed to be added to the
end of transmissions. This is usually used in talk through repeater applications to prevent the
repeater from dropping out between mobile transmissions. The Hang Time can be
individually set on each channel for 0 - 15 seconds.
Time Out Timer - A time-out or transmission time limit can be programmed to automatically
turn the transmitter off. The time limit can be set from 0-254 minutes in increments of one
minute. The timer is automatically reset when the PTT input is released.
7.4.24 CTCSS
CTCSS tones can be provided by an internal encoder or by an external source connected to
the external tone input. The internal CTCSS encoding is provided by a subassembly PCB
module. This provides programmable encoding of all EIA tones.
Some models encode certain extra tones.
Tone frequencies are given in table 4.
