models is also used to service these models. Refer to
Section 1.10 for more information on the intrinsically
safe rating and additional requirements for servicing
intrinsically safe models.

This service manual contains operating, programming, alignment, and service information for the E.F.
Johnson 7780 800 MHz portable transceiver.

1.2.4 SYSTEMS, CHANNELS, AND ZONES
1.2 EQUIPMENT DESCRIPTION
A zone and channel are selected to place and
receive calls. The following describes the relationship
between systems, channels, and zones.

1.2.1 INTRODUCTION
The 7780 800 MHz portable transceiver is available in limited keypad (3-key) and full keypad (15key) models. In addition, standard and intrinsically
safe versions are available (see Section 1.2.3). With all
versions, up to 16 zones can be programmed, and each
zone can contain up to 16 channels resulting in up to
256 total channels. The rotary switch on the top panel
provides channel select, and an option switch provides
zone select if applicable.

Systems
A system as used with this transceiver is a collection of channels (talk groups) belonging to the same
repeater site. A system defines all the parameters and
protocol definitions required to access a site. Up to
1 conventional system and 15 SmartNet/SmartZone
systems can be programmed (16 total). Systems are
used for programming purposes only and are not
selectable by the user.

The 7780 is an 800 MHz transceiver which operates on the 920 channels from 806-824 MHz (mobile
transmit). The receive channels are 45 MHz above
these frequencies from 851-869 MHz. All models can
be programmed for both narrow and wide band operation. With narrow band operation, the channel spacing
is 12.5 kHz and maximum deviation 2.5 kHz; with
wideband operation, the channel spacing is 25 kHz
and maximum deviation is 5 kHz. On NPSPAC channels, maximum deviation is 4 kHz (see Section 1.2.5).

Channels
A channel selects a radio channel or talk group in
a system as follows:
Conventional Mode - A channel selects a specific
radio channel, Call Guard (CTCSS/DCS) squelch
coding, and other parameters unique to that channel.

1.2.2 OPERATING PROTOCOLS

SmartNet/SmartZone Mode - A channel selects a
specific talk group, announcement group, emergency
group, and other parameters unique to that channel.

The 7780 operates on analog channels utilizing
the following operating protocols:

•
•

As previously described, a maximum of up to
256 channels can be programmed with the preceding
modes. The conventional system can be programmed
with up to 256 channels, and each SmartNet/SmartZone system can be programmed with up to 256 talk
groups (channels).

Conventional (non trunked)
SMARTNET II/SmartZone (trunked)

1.2.3 INTRINSICALLY SAFE MODELS
NOTE: Contact your sales representative to determine
the availability of intrinsically safe models.

Therefore it is theoretically possible to program
any combination of these systems that produces up to
256 total channels. However, the maximum number
may be limited by the available memory. For example,
since more memory is required to program a SmartNet
system than a conventional system, the total number

The intrinsically safe versions of the 7780 (see
Section 1.3) meet Factory Mutual standards for operation in certain flammable atmospheres. Basically, the
same service information used to service standard

3.1.4 CONNECTING RPI TO COMPUTER AND
TRANSCEIVER

To Start PCTrunk From Windows 3.1
RPI Information
In the Program Manager, open the PCTrunk
group window. Then double-click the PCTrunk icon.

The RPI provides the required interface between
the computer and transceiver. It converts the RS-232
logic levels from the computer to the 5V logic levels
required by the transceiver microprocessor and vice
versa.

To Start PCTrunk From Windows 95/98
Click the Start button and select the PCTrunk
group. Then double-click the PCTrunk icon.

The current RPI available for programming transceivers of this type is Part No. 023-9800-000. Earlier
RPI’s, such as 023-9750-000 and 023-5810-000 can
also be used. However, the -9800- RPI is the only one
that has the speaker and microphone audio jacks
required to perform the alignment described in Section
6. In addition, it is the only RPI that can be used to
Flash program the transceiver to update the operating
software.

To Exit PCTrunk:
Select File > Exit or press ALT + F4.
3.1.6 PROGRAMMING FILE TYPES
Programming data is stored in a disk file that can
be saved, read, copied, and deleted (see Section 3.3.1).
The file that is stored for each programming session
has the .DAT extension.

Cable Information
The cables from the RPI to the computer and
transceiver are not included with the RPI. The -9800RPI has a female DB9 connector for the computer
connection. Since most computer serial ports have a
male DB9 or DB25 connector, a male DB9 to female
DB9 or DB25 is usually required. This is a standard
cable available at most computer supply stores. A suitable cable is also listed in Table 1-1.

3.1.7 HELP FILES

The cable from the RPI to the transceiver
connects from the RPI to the accessory connector of
the transceiver. A schematic diagram of this cable is
shown in Figure 3-2. The -122 version of this cable
can also be used because the extra wire connected to
pin 8 is not required with this radio.

eight digits from 0-9.

Voice On Control
With SmartZone operation, some remote sites are
designated Voice On Control sites. In these sites, if all
available traffic channels are occupied, control channels become traffic channels when additional traffic
channels are requested. The Voice On Control parameters determine how the radio reacts to various situations that may occur. For example, when a conversation is complete, the radio may look for a control
channel that has become a traffic channel.

3.5.1 INTRODUCTION
The following information describes how
conventional channels are programmed. Conventional
systems do not need to be set up because only one can
be programmed, and it is automatically set up when
the programming file is selected as described in
Section 3.1.6. Up to 256 conventional channels can be
programmed (if no SMARTNET/SmartZone systems
are programmed). Refer to Section 1.2.4 for more
information on systems and channels.

Affiliate Hold Off - With SmartZone operation, this
is the delay time that occurs after acquiring the control channel before it sends an affiliation ISW. This
prevents all radios on the system from sending affiliation ISWs at the same time.
Failsoft Inactivity - Programs failsoft operation (see
Section 2.5.11). If the radio remains inactive (no
receive or transmit activity on channel) while operating in the failsoft mode for the programmed time, the
radio momentarily leaves the failsoft mode and
attempts to find a control channel. If “0” is programmed, the radio does not leave the failsoft mode.

The following is the recommended procedure for
programming conventional channels:
1. Program the radio-wide information as described in
Section 3.4.
2. If other types of systems are programmed, make
sure the conventional system is selected by selecting
Window > Conventional in the menu bar.

Channel” description which follows). The following
modes are available:

The Scan Mode parameter in the preceding
Conventional System Scan List screen selects if
priority channel sampling is enabled on the selected
scan list. It also selects the type of priority channel
(either fixed or the selected) if applicable.

No Priority - Priority sampling does not occur (all
channels are scanned in sequence). The radio transmits on the selected channel.

If the “Priority/Tx Priority” or “Priority/Selected”
mode is programmed, fixed priority channel sampling
is selected. The fixed priority channel must then be
chosen for the scan list. To do this, click the
button in the preceding Modify Scan List
screen and then select the desired zone/channel. Refer
to Section 2.4.12 for more information on priority
channel sampling.

Priority/Tx Priority - Priority sampling occurs
and the priority channel is the one programmed in
the selected scan list. The radio transmits on the
priority channel.
Priority/Tx Selected - Priority sampling occurs
and the priority channel is the one programmed in
the selected scan list. The radio transmits on the
selected channel.
Priority on Sel Chan - The priority channel is
always the selected channel (even if the scan list is
programmed with a priority channel). The radio
transmits on the selected channel.

3.5.3 SETTING UP CONVENTIONAL
CHANNELS
The conventional Channel screen shown in
Figure 3-3 which follows is displayed when a conventional channel is selected. This screen programs
unique channel parameters and also assigns channels
to the selectable zones displayed by the transceiver.

Talkback Scan - No priority sampling occurs
(even if the scan list is programmed with a priority
channel). The radio transmits on the channel of a
call while scanning is halted. Then when scanning
resumes, it transmits on the selected channel.

The general procedure for setting up a conventional channel is as follows. Refer to the descriptions
which follow this procedure for information on the
parameters in the channel screens.

Scan Timers
Scan Hold Time - Sets the delay that occurs before
scanning resumes after a signal is no longer
received (see Section 2.3.11).

1. Make sure that the desired zone is selected in the
Zone box.
2. Select the channel number in the Channels Index
box which is to be programmed with the channel. If
the channel number display mode is selected (see
Section 2.4.2), this will be the number displayed
when the channel is selected.

Lookback Time A - This time determines how
often the priority channel is checked for activity.
Times of 0.25-4.00 seconds in 0.25-second steps
can be programmed.
Lookback Time B - This time determines how
often the priority channel is checked once an incorrect Call Guard (CTCSS/DCS) code is detected.
Since it takes much longer to detect an incorrect
Call Guard signal than a carrier, this time should be
relatively long to prevent the interruptions from
making a message difficult to understand. Times of
0.5-8.0 seconds can be programmed in 0.5-second
steps.

3. To assign a conventional channel, select “Conventional” as the channel type.
4. Click the Modify button to display the screen which

CIRCUIT DESCRIPTION

The divide numbers are chosen so that when the
VCO is operating at the correct frequency, the VCOderived input to the phase detector is the same
frequency as the TCXO-derived input. The TCXOderived input is produced by the reference counter in
IC1. This counter divides the 14.925 MHz TCXO
frequency by 2388 to produce a 6.25 kHz input to the
phase detector. Using a 6.25 kHz reference frequency
allows channels to be changed in 6.25 kHz steps.

the VCO from the receiver and transmitter and the
counters in synthesizer IC1.
A switching circuit on the output of Q10 routes
the VCO signal to the receiver in the receive mode and
the transmitter in the transmit mode. In the receive
mode, the R5V receive supply is applied to R12 and
current flows through R12, D7A, and R51. Since D7A
is forward biased, it presents a low impedance path to
first mixer Q2 in the receiver. D7C is then reverse
biased, so there is a high impedance path to the
transmitter.

The VCO-derived input is produced by dividing
the VCO frequency using the prescaler and N counter
in IC1. The divide number of the prescaler is
controlled by the output signal from the A counter.
The A and N counters function as follows:

The 5V receive supply is also applied to R78 and
current flows through R78, D7B, and R79. This results
in less reverse bias and therefore charge on D7C to
permit faster switching. In the transmit mode, the 5V
receive supply is no longer present, so both D7A and
D7B are reverse biased. D7C is forward biased by the
current path through R50 and R51.

Both the A and N counters begin counting down
from the programmed number. When the A counter
reaches zero, it halts until the N counter reaches zero.
Both counters then reset and the cycle repeats. The A
counter is always programmed with a smaller number
than the N counter. When the A counter is counting
down, the control output to the prescaler causes the
prescaler to divide by 129. Then when the A counter is
halted, the control output changes states and the prescaler divides by 128.

4.2.3 VCO AND TCXO MODULATION
Both the VCO and TCXO are modulated in order
to achieve the required frequency response. If only the
VCO was modulated, the phase detector in IC1 would
sense the frequency change and increase or decrease
the VCO control voltage to counteract the change
(especially at the lower audio frequencies).
Conversely, if only the TCXO was modulated, the
VCO frequency would not change fast enough (especially at the higher audio frequencies).

4.2.5 LOCK DETECT (Q13)
When the synthesizer is locked on frequency, the
LD (Lock Detect) output of IC1 (pin 7) is a high
signal. This turns lock detect transistor Q13 off and the
ULOCK signal fed to the microprocessor is low. When
an unlocked condition is indicated, low-going pulses
appear on pin 7. Q13 then turns on and the ULOCK
signal goes high. The transceiver is then disabled by
the logic and an error condition is indicated in the
display.

However, by modulating both the VCO and
TCXO, the two phase detector inputs remain in phase
and no frequency shift is sensed. This produces a relatively flat audio response. Potentiometer B4 in IC209
is used to balance these signals and potentiometers B1
and B3 are used to set the data and audio deviation
level. IC4 is an amplifier, and R73 sets the frequency
of the TCXO by adjusting the DC bias of IC4.

4.2.6 CHARGE PUMP (Q1, Q2), LOOP FILTER
The charge pump circuit consisting of Q1 and Q2
charges and discharges C4 and C5 in the loop filter to
produce the VCO control voltage. Supply voltage to
Q1 is provided by CPV regulator IC2 on the IF board.

4.2.4 SYNTHESIZER CHIP (IC1)
Synthesizer chip IC1 contains a prescaler, A, N,
and reference counters, and a phase detector. Channels are selected by programming the A, N, and reference counters to divide by a certain number. This
programming is performed by the microprocessor via
the serial data bus which consists of lines PLLSK,
PLLSO, and PLLST (pins 9-11 of IC1).
November 1999
Part No. 001-7780-500

Pulses which control the charge pump are output
by synthesizer IC1 on pins 15 and 16. When the VCO
is on the correct frequency, both phase detector
outputs are in phase. Pin 15 is then high and pin 16 is
low which turns both Q1 and Q2 off. Then if the VCO

ance matching on the output is provided by C15, L9,
L10, C18, C19, and R99. The first IF signal is then fed
to four-pole crystal filter FI3. This filter attenuates
wideband noise, adjacent channels, frequencies
resulting from intermodulation, and other frequencies
close to the receive channel.

frequency is low, the VCO-derived input to the phase
detector is lower than the TCXO-derived input (or the
phase lags the TCXO-derived input). Pin 15 of IC1
then pulses low and turns Q1 on. This charges the loop
filter capacitors which increases the VCO control
voltage. The VCO frequency then increases until the
phase detector inputs are again the same frequency and
phase. If the VCO frequency is too high, pin 16 pulses
high which discharges the loop filter capacitors.

The receive signal from the antenna is fed
through low-pass filter FI7 and the antenna switch (see

4.3.2 IF AMPLIFIER (Q2), LIMITER/DETECTOR
(IC3)
From crystal filter FI3, the IF signal is fed to IF
amplifier Q2 on the IF board. This stage provides the
required input level to the next stage. The signal is
then fed to limiter/detector IC3. This device contains
second mixer and oscillator, limiter, detector, squelch,
and RSSI stages (see Figure 4-1).

The signal is then fed to RF amplifier Q1. Impedance matching with FI1 is provided by L32, C4, C138,
and R104. The RF amplifier is used to recover filter
losses and improve the sensitivity of the receiver. The
output of Q1 is fed to FI2 which is a bandpass filter
similar to FI1. Impedance matching is provided by L5
and C7.

The IF signal is fed in on pin 16 which is the
input of an internal mixer.The 45.225 MHz first IF
signal is mixed with the 44.775 MHz second injection
signal to produce a second IF of 450 kHz. The 44.775
injection signal is produced by multiplying the TCXO
frequency by three. This multiplication is performed
by Q18 and other components.

From FI2 the signal is fed to gate 1 of first mixer
Q2. This is a dual-gate MOSFET device which mixes
the receive frequency with the first injection frequency
to produce a first IF of 45.225 MHz (low-side injection is used). The injection frequency is from the
synthesizer, and it is fed through a low-pass filter
consisting of C22-C24 and L12. This filter attenuates
harmonic frequencies present in the injection signal. A
3-dB pad consisting of R9-R11 provides the required
input level to the mixer, and L11 and C12 provide
matching.

The 450 kHz second IF is fed out of IC3 on pin 3
and applied to ceramic filters FI6, FI5, and FI4. These
filters are used to attenuate wideband noise. A
switching network consisting of D13-D16 routes the
IF signal through all three filters with narrow band and
NPSPAC operation, and through only FI4 with wideband operation. This switching network is controlled
by WIDE and NAR signals from Q19-Q21. The W/N

Impedance matching on the input of Q2 is
provided by C11, L6-L8, and L33. Likewise, imped-

by the switching circuit consisting of D7 and other
components (see Section 4.2.2) and applied to amplifier Q9. Power to this stage and also Q8 is the 7.5-volt
battery supply switched by Q16 and Q17. This switch
is controlled by the switched T5V supply. Therefore,
when the transmit mode is selected, the TX5V supply
goes high which causes the output of Q17 to go low
and turn switch Q16 on.

input signal to these transistors is high for narrow
band channels. Therefore, with narrow band channels, D14/D16 are forward biased and D13/D15
reverse biased and vice versa for wideband channels.
The 450 kHz signal from these filters is then fed
back into IC3 on pin 5 and applied to a limiteramplifier stage. From the limiter the signal is fed to
the quadrature detector. An external phase-shift
network connected to pins 10 and 11 shifts the phase
of one of the detector inputs by 90° at 450 kHz (the
other inputs are unshifted in phase). This network
consists of C17 and ceramic discriminator X1. The
detector is adjusted for wide and narrow band channels by Q3, R8, and C16. The detected audio signal is
then amplified and fed out of IC3 on pin 9.

The output signal from Q9 is fed to driver Q8
which provides additional amplification. Impedance
matching with IC1 is provided by L15, C62, and a
resistive pad consisting of R41-R43. Power amplifier
module IC1 provides up to 3 watts of RF power at the
antenna jack. It contains three internal amplifier
stages, each of which has a separate supply voltage
(VCC1-VCC3). The supply voltage to the first stage
(VCC1) is from the power control circuit, and the
supply voltage to the last two stages (VCC2/VCC3) is
the unswitched battery supply.

4.3.3 SQUELCH CIRCUIT (IC4A/B, IC5A)
The audio output signal on pin 9 of IC3 contains
audio and also high-frequency noise. This signal is fed
to the receive audio and data processing circuits on the
logic board (Section 4.6.1) and also to the squelch
circuit. The amount of noise in this signal tends to be
inversely proportional to signal strength (the higher
the noise level, the lower the signal strength and vice
versa). Therefore, it can be used for squelch control.

4.4.2 ANTENNA SWITCH AND LOW-PASS
FILTER
The antenna is switched between the receiver and
transmitter by an antenna switch consisting of D11,
D1-D3, and several other components. In the transmit
mode, the TMUT input on pin 2 of Q7 is high. The
T5V supply on pin 4 then appears on pin 3 and current
flows through R20, L14, D11, D3, and L1/D1 and
L2/D2. Since D11 and D3 are forward biased, the
transmit signal has a low impedance path to the
antenna.

A bandpass filter that passes only noise frequencies occurring above the audio band is formed by an
op amp in IC3 and external components. The input to
this filter is pin 8 and frequency determining components (R17-R19, C20, C21) are connected to pin 7.
Other components on the input such as Q4 provide
frequency and wide/narrow band compensation, and
thermistors R14/R26 provide temperature compensation. The input audio/noise level is adjusted by R13.
The detected noise output on pin 13 of IC3 is applied
to pin 32 of the microprocessor in the logic unit.

L14/C31, L1/C2/D1, and L2/D2/C17 each form
discrete quarter-wave line that is AC grounded at one
end. When one end of a quarter-wave line is AC
grounded, the other end presents a high impedance to
the quarter-wave frequency. Therefore, L14/C31
isolate the 5-volt battery supply from transmitter RF,
and the other two circuits isolate the receiver. In the
receive mode, D11 and D1-D3 are no longer forward
biased. Therefore, the receive signal has a highimpedance path into the transmitter and a low-impedance path into the receiver. From the antenna switch
the transmit signal is fed to low-pass filter FI7. This
filter attenuates harmonic frequencies occurring above
the transmit band.

4.4 TRANSMITTER DESCRIPTION

4.4.1 AMPLIFIER (Q9), DRIVER (Q8)

the transmit frequency. It is switched to the transmitter

CIRCUIT DESCRIPTION

4.4.3 POWER CONTROL (IC2A/B)

from two external devices. They are 16K x 8
EEPROM IC304 and DTMF encoder IC303. Another
serial port formed by XTXD and XRXD is used to
transfer programming data to and from an external
computer. This port is fed out of the transceiver on
pins 6 and 7 of the accessory connector. Descriptions
of the IC306 pins are located in Table 4-1.

The power output circuit maintains a steady
power output level by controlling the supply voltage to
the first stage in power module IC1 (VCC1). The
output power is monitored using a directional coupler
consisting of L34, L13, C33, C35, D4, D5, and several
other components. Reflected (reverse) power is
detected by L13/D5, and forward power is detected by
L12/D4. These couplers produce a DC voltage that is
proportional to the reverse or forward power.

4.5.2 DISPLAY ASSEMBLY DESCRIPTION
IC1 on the display board is an intelligent LCD
display controller/driver. It communicates with the
microprocessor on the logic board over a serial bus
consisting of MSCK (serial clock) and MSO (serial
data), and DISST (display strobe) signals. IC1 is set
for 1/3 bias and 1/5 duty cycle and drives an 8-character, 14-segment display at a 98 Hz frame frequency.
The LCD display (DS6) has 127 segments that are
driven by a 34-segment signal with 4 common lines.

The forward power signal is amplified by IC2A
and is combined with the reverse power signal on pin
6 of IC2B. If there is no reverse power being detected,
IC2B amplifies only the difference between the
forward power signal on pin 6 and the reference
voltage on pin 5. This reference voltage controls the
power output, and it is set by the control logic through
potentiometer 2 in IC209 in the logic unit.

4.6 RECEIVE AUDIO PROCESSING
As forward or reverse power increases, the output
voltage on pin 7 decreases. Q5 and Q6 then turn off
more which decreases the supply voltage applied to
VCC1 of IC1. Power then decreases to maintain a
stable output. The opposite occurs if forward or
reverse power decrease. The power decrease resulting
from an increase in reverse power prevents transmitter
damage which may result if excessive power is
reflected back into the transmitter. This may occur, for
example, if the transmitter is keyed with a defective
antenna.

4.6.1 BANDPASS FILTER (IC101)
The receive audio and data signal from the IF
module in the RF unit is called DET. It is applied to
IC101 in the receive audio circuit, IC102 in the receive
data circuit, and IC110 in the SMARTNET data
circuit. The receive audio circuit operates as follows,
and the other circuits are described in later sections.
The DET signal is applied to IC101 which is a
bandpass filter which passes frequencies from 3003000 Hz. This attenuates Call Guard (CTCSS/DCS)
signaling and high-frequency harmonics. This filter
also provides de-emphasis of the audio signal.

4.5 CONTROL LOGIC AND DISPLAY
NOTE: A block diagram of the RF and logic units is
located on page 8-3.

On the input of IC101, pin 1 of Q110 is low in the
wideband mode and high in the narrow band mode.
Therefore, R102 is grounded in the wideband mode to
lower the input level to IC101. This maintains a
constant audio output level since the higher deviation
in the wideband mode results in a higher input level.
Also on the input of IC101, the NPSPAC line controlling Q111 is high when a NPSPAC channel is selected
and low at other times. This grounds R167 in the
NPSPAC mode to lower the input level since NPSPAC
channel deviation is higher than narrow band
deviation.

4.5.1 CONTROL LOGIC
The digital control logic is based on 8-bit CMOS
microprocessor IC306. The operating speed is set by
9.8304 MHz crystal X2. A clock shift signal applied
through D301. This signal goes high to shift the clock
frequency slightly when the second harmonic interferes with the receive signal.
A serial data bus formed by MSI, MSO, and
MSCK (pins 49-51) is used to transfer data to and
