MOUNTING THE TRANSCEIVER IN A VEHICLE
If you are not condent that you will be able to install this transceiver please use the services of
a professional installer. Do not risk damaging your vehicle.
• Mount the transceiver where the controls will be easily accessible. In most cases this
will be the side panel of the centre console
• When running power cables, beware of sharp metal edges. Ensure the cable does not
foul the seat adjustment mechanism
• To mount the transceiver, use the bracket and thumbscrews provided. This will ensure
the transceiver remains xed in place at all times, even on rough roads.
• Use the rubber washers provided. Insert these washers between the transceiver chassis
and the mounting bracket to ensure the transceiver does not move.
• Locate the microphone holder so that the microphone cord does not interfere with any
vehicle controls.
• Run the DC cables directly to the battery where possible, even if you have to extend the
power leads using a similar diameter wire.

ANTENNA RECOMMENDATIONS AND INSTALLATION
Mobile antennas
Consider using a helical whip antenna. Helical antennas can be made with quite manageable
length, much shorter than a resonant whip (not helically wound) that would need to be about
2.5m long.
Any whip antenna requires a ground plane to operate eiciently (eg car roof, bonnet or lid of the
boot. There are many antenna mounting brackets for modern vehicles that eliminate the need to
drill holes. You might also consider a removable magnetic antenna base.
Base Station antennas
A xed antenna should be mounted as high as possible and away from metal objects, including
the canopies of trees. A base station antenna can be mounted on a length of pipe supported of
the side of a building. Be careful to ensure clearance from power lines and observe any local
council regulations.
POWER CONNECTIONS
Your transceiver is protected against reverse polarity connection. Modern vehicles are wired
negative to ground (vehicle chassis). Check this by making sure the negative terminal of the
battery is connected to the engine block and chassis.
The red cable is positive, the black cable is negative. Connect the power lead directly to the
battery if possible.
WARNING 12 VOLTS ONLY
Most trucks use 24V DC, often supplied by two 12V batteries in series. In this case take the DC
supply across only one battery.
Never replace the original fuse (10A) with one of a dierent value.
BASIC CHECKS BEFORE TRANSMITTING
1) Connect the transceiver to a 12 volt source, observing the correct polarity.
2) Connect the microphone.
3) Connect the antenna.
4) Turn the transceiver ON.
5) Set the mode switch to CW.
6) Rotate the squelch control fully anticlockwise.
7) Adjust the volume to a comfortable level.
8) Tune to a known channel. Often a beacon frequency will be best.
9) Verify that connecting an antenna increases the received background noise.
05
5. ADJUSTMENT OF SWR (Standing Wave Ratio)
The antenna you intend to use with this transceiver must be “matched” or tuned to the
operating frequency to ensure maximum energy from the transmitter is transferred to the
antenna. This means minimizing any energy that is reected back down the coaxial cable from
the antenna to the transmitter, as this can damage the output devices.
This mismatch is called the SWR or Standing Wave Ratio and is simply the ratio of the forward
power, compared to the reected power. Less reected power is best !
Use a dedicated SWR meter for this adjustment.
To check the SWR, set the transceiver to Channel 20 Bank D, which is approximately mid band
and select either AM or FM mode.
Ensure the antenna is clear of tress and nearby metal objects which can inuence the SWR
reading.
Connect the SWR meter with a short cable terminated in PL-259 plugs between the transceiver
and the meter (normally supplied with the meter). Then connect the antenna cable (which will
be longer) between the SWR meter and the transceiver.
Set the SWR meter to CAL, connect the microphone and operate the PTT. You should see the
meter respond. Adjust the calibration (CAL) knob so that the meter reads just on full scale
deection. Change the switch position on the SWR meter to “SWR” and read the level on the
meter. A reading of 1 is perfect whilst a reading of 2 is the maximum normally considered
acceptable.
If the reading is higher than 2, the length of the antenna needs to be adjusted.
If increasing the channel number (increasing the frequency) causes the SWR to improve ie the
reected power is lower, the antenna is too long. If increasing the channel number causes the
SWR to get worse, the antenna is too short.
Most base station antennas have adjustable elements, but most mobile antennas are helically
wound. Shortening the antenna is irreversible, so only remove a few millimetres at a time.
Remember to re-calibrate the SWR meter every time a measurement is made of the frequency
is changed.
IF YOU ARE NOT CONFIDENT IN ADJUSTING YOUR ANTENNA ENLIST THE ASSISTANCE OF
SOMEONE MORE EXPERIENCED FROM THE LOCAL AMATEUR COMMUNITY.
06
10 METRE BAND PROPAGATION
The 10 metre band can yield very surprising results in terms of DX contacts.
Whilst scanning the band can yield few results, once a call is made the response can be
amazing. Seems many DX stations are just waiting to be called !
Depending on the level reection in the ionosphere, signals can propagate further than normal,
during “greyline”, the transition from sunlight to darkness. So by working out when greyline
occurs at a destination and calling at that time, good results can be achieved.
On any HF band ,something you will hear from stations calling CQ is that they will mention
“Long Path” or “Short Path” and these two terms need some explanation. Normally stations with
a directional antenna will point the antenna towards the target area. This is known as “Short
Path” and is the most direct distance to the target. However sometimes better results will be
obtained by rotating the antenna to point in the opposite direction, so that the signal has to
travel more than halfway around the earth to reach the target. This is called “Long Path”.
Sometimes Long Path signals are stronger than Short Path signals, and this is because often
Long Path signals travel vast distances over water. Short Path signals reecting o the F2 layer
of the ionosphere can travel 1800-3500Km between hops, so a typical short path might involve 5
or 6 hops, attenuating the signal at each reection.
During daylight there are two upper layers in the ionosphere, the F1-layer at approximately 150-
200km and the F2 layer at 250-400km. After sunset these two layers merge into the F layer and
split up again into F1 and F2 layers at sunrise. During night the F layer loses ionisation density,
and the ability to reect signals back to Earth. But sometimes the F-layer is just dense enough
to reect the signal back, with a less acute angle, causing the signal to be directed to another
part of the ionosphere thousands of km’s ahead, without reecting o the ground.
There are many possible means of propagation, and the above is by no means a complete
explanation.

Rotate clockwise to switch on the radio and set the desired volume level. Under normal
operating state, the VOLUME control is used to adjust the output volume obtained either by
the transceiver speaker, or the external speaker, or the external PA speaker, if used.
This control is used to cut o or eliminate receiver background noise in the absence of an
incoming signal. For maximum receiver sensitivi, it is desired that the control be adjusted
only to the point where the receiver background noise or ambient background noise is
eliminated. Rotate fully anticlocise then slowly clockwise until the receiver noise
disappears. Any signal to be received must now be slightly stronger than the average
received noise. Further clockwise rotation will increase the threshold level that a signal must
overcome to be heard. Only strong signals will be heard at a maximum clockwise setting.
This switch is used to control echo eect.
This switch is used to control intervals of echo sound.

LICENSING REQUIREMENTS
You need an Australian amateur radio qualification to operate this equipment.
In Australia, the ACMA has powers to make technical specications for radiocommunications
equipment under the Radiocommunications Act 1992. However, the primary tenets of the
Amateur Radio service are technical investigation, experimentation and self-training; hence,
Australian Standards for radiocommunications equipment are not applicable to amateur
stations.
No matter what amateur licence (Foundation, Standard or Advanced) you hold, you may
possess any piece of equipment manufactured specically for the global amateur market,
provided that you operate it in accordance with the type of licence you hold, even if the item of
equipment is capable of operating in certain spectrum segments that are not available to
amateurs in Australia.
The latest Regulations handbook for radio Amateurs in Australia can be found here:
https://vkregs.info/wp-content/uploads/2024/08/VK-Regulations-Handbook-August-2024.pdf
RF SAFETY
All transmitters and most receivers radiate some RF energy. Be aware that this energy may
interfere with nearby equipment. In particular do not operate this equipment if:
You have a Pacemaker, implantable cardiac debrillator or other active medical device
WITHOUT FIRST CHECKING WITH YOUR DOCTOR.
This transceiver is not “Intrinsically Safe” and should not be used in areas containing a
potentially explosive atmosphere. This means areas containing ammable gas, metallic
powders, blasting caps, explosives, unvented fuelling areas etc
OPERATING PROTOCOLS AND DECORUM:
Before transmitting on any frequency, always listen rst for activity. The frequency you have
selected may already be in use, and you may not be able to hear a distant station
communicating with a local station. If the frequency is already in use, select an alternative.
ROAD SAFETY
Check with your local state regulations to see if operating this transceiver whist mobile is legal.
The onus is on the driver to maintain proper control of the vehicle at all times.

BEACON PROPAGATION
It’s a great idea to check 10 metre amateur radio beacon activity to see how good the band
conditions are. Check VK6RBP on 28200 Khz and ZL2MHF on 28229 Khz for an indication of
propagation.
There is an internation service called the IBP (International Beacon Project) where stations
around the world transmit at given times, sequentially on the same frequency (28200 Khz).

Each beacon transmits once on each band once every three minutes, 24 hours a day.
A transmission consists of the callsign of the beacon sent at 22 words per minute followed by four
one-second dashes. The callsign and the first dash are sent at 100 watts. The remaining dashes are
sent at 10 watts, 1 watt and 100 milliwatts. At the end of each 10 second transmission, the beacon
steps to the next higher band and the next beacon in the sequence begins transmitting.
In addition there is a network of receiving stations around the world monitoring beacons and
reporting their results via the internet. This network is called the “Reverse Beacon Network”
See: https://www.reversebeacon.net/ for details.

Programming your HS4 10 metre transceiver
The HS4 transceiver allows user customization of channel data for the 10 metre amateur band.
Frequencies for allocated channel numbers (Tx and Rx), CTCSS/DTS encode and decode
frequencies, as well as Echo, Busy, Hi-Cut NB/ANL, RB and scan can all be customized to the
user preference.
Programming access is available via the Mini USB port on the rear panel using the programming
cable supplied with the transceiver. We have programmed your transceiver to include Australian
repeater frequencies including Tx oset and CTCSS where applicable and a specic channel in
the EMG position for each sub-band.
The architecture of this transceiver allows for 6 sub-bands within the 10 metre amateur radio
ITU allocation. Sub bands A-E contain 60 channels each, whilst sub band F contains 25 channel
allocations.
Data can be read from the transceiver and saved on a PC for editing. Edited les can be
uploaded to the transceiver, overwriting the original information.
