2. Overview

Your 8528 HF SSB transceiver employs the latest concepts in design and reliability for long range communications. It has been designed for 12V DC operation in fixed base and mobile installations.

There are two versions of the transceiver; one with front panel control and the other with extended control. The extended control unit consists of a transceiver and a separate control head which can be located up to100 metres away from the transceiver.

The control head can also be used as an accessory with the front panel control version to enable local and extended control of the transceiver.

You operate the transceiver through the front control panel, or control head, which contains sealed membrane switches (or buttons) and a liquid crystal display (LCD). The LCD shows the selected channel number along with the transmit and receive frequencies. In addition, the display shows messages about the operation of the transceiver.

Continual research and development has produced different versions of the 8528 SSB HF transceiver. The different version means a later issue of EPROM which provides different operating features. To check the version of your transceiver, refer to section 4, Review the EPROM version and options. This issue of the handbook incorporates operating information for EPROM versions

4.1 to 4.3.

8528 HF SSB transceiver 2-1

Overview

The main facilities and features of the transceiver are:

• channels

• selective call

• scanning

• free tuning receiver

• tone calling

• telephone interconnect

• ARQ-FEC.

Channels

Selective call

Scanning

Your transceiver has a capacity of 600 channels, these cover:

• transmit frequency range 2 MHz to 24 MHz

• receive frequency range 0.25 MHz to 30 MHz.

A maximum of 501 transmit and receive channels can be pre-programmed in the factory, or by an authorised Codan dealer. You, as a user, can program the remaining 99 channels from the front panel as P-channels.

This facility allows you to transmit a call to a single transceiver or a group of transceivers. To receive a selective call, your transceiver must be fitted with option SD.

Your transceiver can store details of up to ten stations that have called you while your transceiver was left unattended.

This facility scans selected channels for audio signals. You can program a maximum of 15 channels to be scanned in sequence for audio signals. When a selective call decode option (SD) is fitted, a maximum of eight selective channels can be programmed and scanned.

2-2 8528 HF SSB transceiver

Overview

Free-tuning receiver

Tone calling

Telephone interconnect

ARQ-FEC

Your transceiver can be used as a free-tuning receiver covering the world broadcast bands over the frequency range of 250 kHz to 30 MHz.

This facility allows you to send a tone call (two tones transmitted simultaneously) to signal another transceiver.

A base transceiver can be connected to an IPC-500 telephone interconnect. This allows you to use your transceiver to make telephone calls into the public telephone system.

For remote data transmission applications, your transceiver can be connected to a data source comprising computer terminal and interface modem. There are two types of transmission available:

• ARQ - Automatic Repeat Request

• FEC - Forward Error Correction.

Mounting the transceiver

In mobile installations, the transceiver must be mounted in a position that will not cause injury to occupants in the event of a motor vehicle accident.

Mount the transceiver and control head in a position that allows:

•••• easy access to the control panel

•••• a free flow of air through the rear cooling fins.

There are two types of mounting cradles that can be used when installing your transceiver:

• code 117 mounting cradle—front entry

• code 118 mounting cradle—top/bottom entry.

Both types of cradle (supplied with 6 metres of DC power cable) can be used to mount the transceiver. You must determine the mounting position to best suit your needs.

Installation

8528 HF SSB transceiver 3-3

Remove the front and rear fixing screws of the transceiver side rails (the centre screw to be left untouched).

Note: Adaptor plates have to be fitted to the transceiver

side rails to secure the transceiver to the cradle.

Secure the adaptor plates flush to the transceiver side rails with the new screws provided, and fit one 'O' ring over each projecting stud. The adaptor plates projecting studs fit into the slides in the cradle.

Insert the transceiver adaptor plate studs into the cradle slides and push fully into the cradle.

Secure the transceiver into the cradle with the spring clips.

8528 HF SSB transceiver 3-5

Installation

Mounting the extended control head

The control head must be connected to the transceiver before power is applied. Failure to do this may result in damage to the transceiver in the following ways:

•••• the internal fuse blows and must be replaced

•••• the control head fails to operate. The power must be

disconnected from the transceiver and then reconnected and switched on.

Step

Action

Remove the two cradle screws and washers securing the mounting cradle to the control head.

Secure the mounting cradle into position. Ensure there is sufficient space at the rear of the cradle for the control cable.

Secure the control head to the mounting cradle with the two screws and washers.

Mount the transceiver (refer to Mounting the transceiver on page 3-3).

Step Action

3-6 8528 HF SSB transceiver

Installation

Connect the interface cable between the control head and transceiver. Ensure the cable connectors are securely fastened to the control head and the transceiver.

Notes: The extended control head is supplied with a cable

approximately 6 m long. To enable correct installation, the cable has different connectors at each end.

If necessary, remove the cover from one connector to pass the cable through restricted openings.

If the cable is too long, gather the excess neatly at one point.

Connect the extension speaker cable to either the control head or the transceiver.

8528 HF SSB transceiver 3-7

Installation

Power supply

Ensure that the power supply to operate your transceiver is 12V DC. Transceiver series 8528H operating with the 400 watt PA (type 4404) will require a 24V DC supply.

Power can be provided by either a 12V battery (for mobile installations) or a suitable AC power supply (for base station installations).

All installations should be checked by a qualified technician before power is applied to the transceiver.

The heavy duty six metre length of power cable—supplied with the vehicle mounting cradle for mobile installations— has been selected to minimise the voltage drop between the battery and transceiver when in transmit mode. Installation using a smaller core cable size is not recommended.

All cables should be protected from sharp edges and mechanical abrasions.

For mobile installations, it is recommended that a suitable cartridge fuse (32 Amp-accessory code 711) is fitted in the active wire, close to the battery, to protect the power cable from the possible risk of fire through damaged insulation coming in contact with the vehicle chassis. Normal glass inline automotive fuses are not recommended. The transceiver is fitted with adequate internal protection.

Connect the power cable between the transceiver and the battery or the transceiver and AC power supply.

Note: In extended control installations where the

power and control cables are long and follow a common path, keep the cables separate by a minimum of 200 mm. The cables can be brought together for short distances, for example, to pass through the same hole in a bulkhead. Failure to observe this warning will cause distortion of the transmitted audio signals.

3-8 8528 HF SSB transceiver

Grounding

In all installations an adequate ground, or earth, is essential for satisfactory operation of the transceiver.

A chassis ground or earthing position is provided on the rear panel of the transceiver.

The control head should also be earthed.

In fixed installations, install an earth cable between the transceiver ground screw and an earth point. Use copper braid or heavy duty cable.

Antennas and antenna tuners

Correct installation of these two units is of prime importance to the operation of your transceiver.

To obtain the best performance and good radiation efficiency from your transceiver installation, it is important to consider the physical location-distance from the transceiver-and earthing of the antenna and tuner.

Installation

Detailed and specific installation instructions are provided with each antenna and antenna tuner. These instructions must be used to gain the best possible results from your antenna, antenna tuner and transceiver.

Transmitting

It is important when transmitting to use the microphone to its best advantage. By following the notes under Using the microphone you will obtain the best transmitting results. This section covers two topics:

• using the microphone

• transmitting a message.

Using the microphone

To connect the microphone to the transceiver; push the microphone plug gently into the microphone socket and fasten the locking ring finger tight, do not over tighten.

Please observe the following notes when using the microphone.

• Hold the microphone side-on and close to your mouth.

• Press and hold down the PTT (press to talk) button.

• When starting a transmission, always state the call sign of the person you are

addressing and then your own call sign.

• Speak clearly at normal volume and rate.

• Do not use abusive language, remember others may be listening to your

conversation and it can offend.

• Use the word 'over' to indicate you have finished speaking and release the PTT

button.

• The transceiver has a 'time out' facility that stops the transmission after a pre-set

period. This facility prevents problems occurring if you have jammed the PTT button down. The time out period can be adjusted to suit your requirements; refer to section 11, Changing the set-up options.

5. Using selective call

Selective call allows you to call an individual transceiver or a group of transceivers. This can be best likened to a normal telephone system where the called station has a unique calling address or number. However, the operator can also call a group of stations if desired.

Each transceiver has its own identification number. The identification number is a four digit code that is either:

• self programmed into the transceiver using the front panel buttons

• pre-set at the factory.

The selective call feature operates by the transmission and reception of coded signals. These signals contain the identification number of the transceiver being called (the called address) and the number of the transceiver making the call (the self-identification).

All 8528 transceivers can make selective calls. To receive a selective call however, option SD must be fitted to your transceiver.

All displays in this section show examples of channel and frequency numbers. You must insert your selected channel and frequency numbers.

Setting up selective call

There are several features that need to be set up before selective call is used:

• the preamble time period

• the called address

• the self-identification address

• the beacon on or off.

You may cancel the procedure at any time by turning the transceiver off (press the Power On/Off button). Turning the transceiver off stores any changes you made to the features.

This procedure is only appropriate for transceivers with software issue 4.1 or greater. If you own a transceiver with a software issue before 4.1, this procedure will require you to reposition an internal link. Further information on this link can be found in section 11, Changing the front panel link.

Once you have commenced this procedure, if no action is required you can skip through all the features by repeatedly pressing the Call button.

Notes: A long preamble is required when scanning selective

calls.

The reason for a long preamble is that during scanning, the preamble has to be present throughout the time it takes to scan all eight selective call channels.

Do not use identification addresses ending in '00' and

'99' as they are used for the group call and beacon

facilities.

You must always enter information within 60 seconds

of pressing the Enter button, otherwise the transceiver

reverts back to the normal mode.

5-22 8528 HF SSB transceiver

Using selective call

Reviewing the list of received calls in memory

Your transceiver is able to record up to 10 calls in memory from various stations. These may be on different channels if your transceiver is on scan mode. These calls are recorded in a memory stack awaiting your review. If a station calls more than once on the same channel, your transceiver only records one of the calls. If more than 10 calls are made to your transceiver, the first call stored in memory is deleted to make room for the latest call.

Ensure your transceiver is not in the scan mode before commencing this procedure.

A permanent or brief loss of power to your transceiver will delete information

stored in memory . Ensure you record or use all the information stored in the

memory stack before switching off the transceiver.

Notes: If the transceiver power is lost momentarily (such as during starting the

vehicle engine ), the call memory is retained but the number is lost.

Switching the transceiver off using the Power On'Off button deletes all calls stored in the memory stack.

There are two methods of reviewing the list of received calls held in the memory:

• using the Display button to review all calls in the memory

• using the Recall button have direct recall of the called channel.

Using the beacon feature

The beacon facility is used to check signal conditions between two transceivers fitted with selective call.

The beacon facility has two modes of operation:

• selective beacon mode

• base station (99) beacon mode.

Selective beacon mode

This facility is only available to transceivers with EPROM version 4.1 and above.

With the beacon facility enabled on a transceiver, it will transmit a beacon signal on receipt of a selective beacon call from another transceiver. Refer to the Selective beacon mode procedure on page 5-30.

Both transceivers must be on the same channel, or the receiver of the selective beacon call must be scanning through the same channel.

(99) beacon mode

The 99 beacon mode is recommended for use in base station applications and for those transceivers that may have operating selective call but do not have the beacon mode facility.

With a base station enabled for beacon mode, it will transmit a beacon signal on receipt of a selective call ending in 99. Refer to the (99) beacon mode procedure on page 5-31.

The thousand and hundred digits of the address must be the same for both the beacon transmitting and receiving stations.

If mobile transceivers have the beacon enabled, the first two digits of each mobile transceiver's self-identification address should be set to a different number so that they do not all transmit a beacon response together.

Using selective call

8528 HF SSB transceiver 5-27

Using selective call

General information for both modes of operation

The beacon signal consists of four long tones.

Self-identification addresses ending in 99 should be avoided as these will cause confusion.

No alarm or call is recorded at the receiving transceiver, only the Tx indicator flashes.

If the receiving transceiver is in scan mode, the scan sequence recommences immediately.

Normal selective call operation is not affected.

Using the external alarm feature

If your transceiver has option SD fitted, an external alarm facility is made available through the external alarm socket on the rear panel (refer to figure 2.3).

A pair of relay contacts are wired to the socket, which close for two minutes when your transceiver receives a selective call. The relay contacts can be used to operate an alarm bell or buzzer.

• Relay contact rating: 50V DC - 1 Amp

• Plug connections: pins 2 and 3.

Further details on the socket can be found in section 13.

These contacts must not be used to switch voltages greater than 50V, or loads that draw more than 1 Amp.

Testing the selective call functions

This is a special test mode which will not be required for normal operations.

In this mode, the transceiver decodes all selective call signals, and displays the address to which it was sent and the self identification of the calling station.

No called alarms or revertives are generated. (A revertive is a signal transmitted back from the receiving transceiver to indicate message received and decoded satisfactorily.)

Ensure your transceiver is switched off before entering this mode.
