CO1-2 Combiner

INDICE Page 3 of 36

We congratulate you on the choice of the Combiner CO1-2.

With this device you can add the power of two linear amplifiers, even those not

produced by SPE.

It is recommended that amplifiers not produced by SPE are as equal to each other

as possible to avoid that the strong difference in power between the two is

dissipated by the balancing resistance contained in the Combiner itself.

In regards to SPE production amplifiers, thanks to the unique use of ALC, the

difference in output of the two amplifiers is automatically reduced to the

minimum (the highest output is reduced to approximately the same output as the

less powerful amplifier) in order to make the dissipation of the balancing

resistance insignificant.

In addition, all Expert amplifiers retain their characteristics such as CAT control,

use of the internal ATU, and the ability to select up to six antennas (see chapter

3.3).

The Combiner CO1-2 optimizes the investment of the station as it allows the

increase of the power in successive steps whilst still maintaining the two

separate amplifiers available for DXpeditions or field days.

The device is not managed by software, so no upgrading will ever be necessary.

IMPORTANT

Before installing and using the equipment, we recommend that you read the

instructions in this manual carefully.

Failure to follow these instructions will result in voiding the warranty.

Keep the manual, it contains important information regarding the safety and

correct use of the Combiner.

HOW TO READ THIS MANUAL

The manual can conceptually be divided into three parts:

• First part, from chap. 1 to chap.3.

Shows the main features of the CO1-2 and how to connect it.

• Second part, from chap. 4 to chap. 5.

Describes how to operate and maintain the CO1-2.

• Third part, chap. 6.

Describes the use of the software provided for remote control of the two Expert

amplifiers used.

PRECAUTIONS

Explicit definitions

WORD

DEFINITION

WARNING!

Risk or danger of fire or electric shock to people.

Possible damage to the amplifier.

NOTE:

Serious problems if not observed. Danger of fire or electric shock for the operator,

or damage to the equipment.

WARNING!

DO NOT disconnect the coaxial cables when the device is in transmission mode.

This could cause a risk of electric shock or burns.

WARNING!

DO NOT modify the internal settings of the device. This could reduce the performance

of the Combiner or damage it.

WARNING!

Before powering up the device, check the value of the power supply which must be

compatible with the device.

WARNING!

DO NOT use the device, before you have connected it to the protective earth.

WARNING!

DO NOT allow metal objects or wires to penetrate inside the appliance.

WARNING!

DO NOT obstruct the front and rear air intakes of the unit.

ENSURE that no objects impede the correct functioning of the fans.

WARNING!

DO NOT expose the equipment to rain, snow or any liquid.

WARNING!

AVOID locations without adequate ventilation. Proper dissipation would be impeded

resulting in damage to the device.

WARNING!

DO NOT touch the device with wet or damp hands. This could cause electrocution.

DO NOT open the combiner without first disconnecting it from the devices connected to

it.

To clean the Combiner DO NOT use chemical agents like alcohol or benzene, as the

plastic surfaces could be damaged.

AVOID using the Combiner in areas with temperatures below 0° C (+32°F) or above

+40°C (+104°F).

AVOID using the Combiner in locations that are very dusty, damp, have high humidity or

that are in direct sunlight.

AVOID placing the Combiner against walls where the circulation of the air would be

obstructed and the noise of the fans would be reflected toward the operator.

AVOID permitting children to play with the Combiner.

Information for Users on Collection and Disposal of Old Equipment and Used

Batteries.

These symbols on the products, packaging, and/or accompanying

documents mean that used electrical and electronic products and batteries

should not be mixed with general household waste.

For proper treatment, recovery and recycling of old products and used

batteries, please take them to the relevant collection points, in accordance

with your national and local legislation.

The use of the Combiner CO1-2 is allowed by operators with an adequate license.

Its installation and its use (power, band, transmission mode, etc.) must comply

with the current laws of the State in which it operates.

The Combiner is essentially passive and therefore does not require FCC

certification for radio amateur use (if required).

However, where such certification is required, it is essential that the linear

amplifiers used are FCC certified.

2. GENERAL INFORMATION

2.1 Power supply.

The Combiner is powered by an external source of 13.8 V DC nominal (15.5 V DC

max).

Considering the low current required (1 A max.), the transceiver power supply can be

used.

This voltage is shown on the "PORT OUT" connector in order to supply the antenna

switch (optional).

There is a slow 1 A fuse inside the Combiner.

2.2 External Ground Connection (Gnd).

WARNING! Before connecting an external ground as described below, check with

a qualified electrician that your national wiring codes a connection.

To reduce TVI, BCI and other RF problems it is best to connect the amplifier to a good

RF ground. (Note that an RF ground is different to an electrical ground which is

necessary for the prevention of electrical shock).

The inductance of such a connection needs to be low, so the connection to ground

should be as short and direct as possible.

Large-section copper conductors should be used for this purpose.

It is recommended to terminate the earth connection with a small metal plate.

The best solution is to have several ground stakes, driven into the ground, and these

ground stakes also need to be tied to your main grounds.

Good results can often be achieved by using correct earthing clamps, connected to the

main water supply pipe (note, many water pipes are now made out of plastic).

DO NOT use central heating pipe work.

AVOID the electric circuit ground of the building (to be used for 50/60 Hz safety only).

WARNING! DO NOT connect to gas pipes as there will be a danger of

explosion!!

2.3 Kit Cables (option).

A cable kit can be provided to connect between the two amplifiers and the Combiner;

each cable is long enough to place the three devices stacked or side by side.

For other provisions involving longer lengths refer to the chapters below.

The Kit consists of n. 6 cables (see page 6):

n.1 PORT Cable, n.1 CAT Cable, n. 2 x COMBINER Cable, n. 2 x SPLITTER Cable.

The CAT Cable, for construction reasons, is supplied in two versions to choose from

when ordering:

CAT Cable / CAT for connection to all CATs.

CAT Cable / Band Data for the "BAND DATA" connection.

2.4 “PORT IN” Connector.

If you use two EXPERT amplifiers from this connector, use a Y-cable to interconnect the

"PORT" connector of each amplifier.

This allows the synchronization of the two amplifiers; if not, an alarm will occur.

The two amplifiers are synchronized when their settings are perfectly identical, therefore

this cable is necessary in order for the Combiner to function properly.

This connector is not used with non-Expert amplifiers.
