2.0 INTRODUCTION
This section explains the basic operating procedures for the SS-3900EGHP Amateur 10 meter mobile
transceiver.
2.1 CONTROL AND CONNECTIONS
2.1.1 FRONT PANEL
Refer to the above Figure 2-1 for the location of the following controls.
1. ON/OFF VOLUME CONTROL
This knob controls the volume and power to the radio. To turn radio on, rotate the knob clockwise.
Turning the knob further will increase the volume of the receiver.
2. SQUELCH CONTROL
This knob is used to eliminate background noise being heard through the receiver, which can be
disturbing when no transmissions are being heard through the receiver. To use this feature, turn the
knob fully counterclockwise and then turn clockwise slowly until the background noise is just
eliminated. Further clockwise rotation will increase the threshold level which a signal must overcome
in order to be heard. Only strong signals will be heard at a maximum clockwise setting.
3. MIC GAIN CONTROL
Adjusts the microphone gain in the transmit modes. This controls the gain to the extent that full talk
power is available several inches away from the microphone.

going to the next step.
2. Turn unit on by turning the VOL knob clockwise.
3. Set the VOL to a comfortable listening level.
4. Set the MODE switch to the desired mode.
5. Listen to the background noise from the speaker. Turn the SQ knob slowly clockwise until the
noise just disappears. The SQ is now properly adjusted. The receiver will remain quiet until a signal
is actually received. Do not advance the control too far or some of weaker signals will not be heard.
6. Set the CHANNEL selector switch to the desired channel.
7. Set the RF GAIN control fully clockwise for maximum RF gain.
8. Adjust the COARSE/FINE control to clarify the SSB signals or to optimize AM/FM signals.
2.3.2 PROCEDURE TO TRANSMIT
1. Select the desired channel of transmission
2. Set the MIC GAIN control fully clockwise.
3. If the channel is clear, depress the push-to-talk switch on the microphone and speak in a normal
voice.
2.4 ALTERNATE MICROPHONES AND INSTALLATION

- 6 -
For best results, the user should select a low-impedance dynamic type microphone or a transistorized
microphone. Transistorized type microphones have low output impedance characteristics. The
microphones must be provided with a four-lead cable. The audio conductor and its shielded lead
comprise two of the leads. The third lead is for transmit control and fourth is for receiving control. The
microphone should provide the functions shown in the schematic below (Figure 2-3).

SS-3900EGHP
CIRCUIT
DESCRIPTION
3.0 INTRODUCTION
This section explains the technical theory of operation for the SS-3900EGHP Amateur 10 meter mobile
transceiver.
3.1 PLL CIRCUIT
The Phase Lock Loop (PLL) circuit is responsible for developing the receiver’s first local oscillator
signal and the transmitter’s exciter signal. The PLL circuit consists primarily of IC5, IC10, TR24,
TR25 and TR26. The PLL circuit is programmed by the rotary channel switch GPS-0501. The GPS-
0501 communicates the correct binary data information to the programmable divider inside of IC5. IC5
then controls the VCO (Voltage Controlled Oscillator) to oscillate on the correct frequency. This signal
is fed either into the receiver’s first mixer (for receive operation) or the transmitter’s mixer (for
transmit operation).
3.2 RECEIVER CIRCUIT
The incoming RF signal comes into the radio via the antenna and into the front-end pre-amp, TR17.
The RF signal is fed into the mosfet mixer circuit of TR18 and then into the AM/FM/SSB IF section of
the receiver (depending on the mode of operation). The signal is then detected by either the AM/FM
detector or product detector and then fed to the audio amplifier section of the receiver and finally out to
the speaker.
3.3 TRANSMITTER MODULATION CIRCUIT
(i) The transmitter modulation circuit modulates the low-level RF signal from the PLL exciter circuit
with the user’s audio voice signal from the microphone. The audio from the microphone is then
amplified and fed into the transmit amplifier circuit.
(ii) If the transceiver is in the AM mode, the AF Power amplifier modulates the last RF amplifier,
which produces a true amplitude modulated RF signal.
(iii) If the transceiver is in the FM mode, the audio signal is not mixed with 10.6975MHz oscillator but
instead phase modulates the basic exciter signal from the PLL circuit in the TX mixer.
(iv) If the transceiver is in the SSB mode, the audio signal is mixed with the 10.6975MHz oscillator
for LSB and 10.6925MHz for USB in IC3.
3.4 TRANSMITTER AMPLIFIER CIRCUIT
The transmitter takes the basic exciter signal from the TX mixer and amplifies it through a series of
amplifiers consisting of TR46, TR45, TR44, TR43 and TR56 where it is then sent out to the antenna
connector.

The inherent quality of the solid-state components used in this transceiver will provide many years of
continuous use. Taking the following precautions will prevent damage to the transceiver.
(i) Never key the transmitter unless an antenna or suitable dummy load is connected to the antenna
receptacle.
(ii) Ensure that the input voltage does not exceed 16 VDC or fall below 11 VDC.
(iii) During alignment, do not transmit for more than 10 seconds at a time. Transmitting over long
periods can cause heat built-up and cause transmitter damage.
5.1 PERIODIC INSPECTION
This unit is aligned at the factory to deliver maximum performance. However, continued performance
cannot be expected without periodic inspection and maintenance. Important points to be checked
regularly are as follows;
Check Item Action
Whip antenna (option) If cracked or broken, replace it.
Coaxial cable If sheath is cracked, seal with vinyl tape. If
immersed with water, install new coaxial
cable.
Coaxial & power plug
connections
If loosened, reconnect. If corroded, clean
contacts.
Battery connection If corroded, clean power terminals.
Ground terminal If corroded, clean terminal.
5.2 FUSE REPLACEMENT
To protect the equipment from serious damage, a fuse is provided on the power supply lines. The fuse
protect against overvoltage / reverse polarity and internal fault of the equipment. If the fuse has blown,
first find out the cause of the trouble before replacing it. A fuse rated for more than the transceiver
requirement should not be used, since it may permanently damage the equipment. Damage due to
overfusing is not covered by the warranty.
