PACKAGE CHECKLIST

QtyDescriptionItem
1 100W FM Transmitter
1 IEC AC power cord
1 MPX audio lead

This equipment requires an antenna and feeder cable that presents 50 ohm load (SWR 1.4 or less, 16 dB or more return loss) at the operating frequency.

Ideally the antenna should be mounted at least 20 meters high and clear of any surrounding objects to get maximum range and more importantly to reduce risk of radio frequency radiation to personnel. When an antenna with 3dBi or higher gain towards the horizon is mounted at least 20 meters in height off ground and using 100 watts of transmitter power, power flux density measurements made at ground level directly under the antenna show less than 1 W/m2. Several European countries use a value for the power flux density of 10 W/m2 as a basis for considering whether or not an area is safe. The issue of radio frequency radiation limits is a contentious one and work in this field is continuing worldwide. Under no circumstances should an antenna be mounted and used at ground level or within a few meters of personnel.

THIS TRANSMITTER COMES IN THREE VERSIONS

MPX. - This is the low cost version, it's not intended for the novice or beginners. The audio input is raw MPX without any audio limiting or stereo coder circuitry, this must be provided externally in accordance with the recommendations of http://www.aareff.com/ETR132.pdf

Stereo Version. - This is identical to MPX version but with a stereo coder built in. Again it does not include audio limiting, so it's not recommended for the novice or beginner. External limiting need to comply with the recommendations of http://www.aareff.com/ETR132.pdf

Stereo and Audio Processing. - Most small radio stations and beginners will use this version, this is because it includes audio processing circuitry and suitable limiting to keep the transmitter in compliance with the maximum bandwidth permitted by the international regulations. There is also access to the MPX in and out on the back panel which allows all known RDS units to be connected.

USA TECHNICAL REQUIREMENTS

Some versions of this transmitter do not include internal audio limiting. To maintain compliance with the FCC rules and technical requirements the audio source / feed should be level controlled to prevent over deviation and excessive use of bandwidth by means of an external audio limiter and/or processing device, MPX stereo generator and/or RDS generator. More information on this is at is in section 2.1047 Modulation characteristics and section 2.1049 Occupied bandwidth at http://www.gpo.gov/fdsys/granule/CFR-2011-title47-vol1/CFR-2011-title47-vol1-sec2-1047/content-detail.html

EU REGULATORY REQUIREMENTS

Some versions of this transmitter do not include internal audio limiting. To maintain compliance with the EU ETSI standard the audio source / feed should be level controlled to prevent over deviation and excessive use of bandwidth by means of an external audio limiter and/or processing device, MPX stereo generator and/or RDS generator. More information on this in section 8 Audio Processing Limiter at http://www.aareff.com/ETR132.pdf

This product complies with EMC directive of the European Union. To meet this directive the user or installer must follow the wiring instructions in the this user manual

This equipment is not intended for installation by an unqualified end user, the installer must have competent RF engineering skills and EMC knowledge at their disposal. The whole transmission system, including the antenna system and external audio limiting, should be installed in the EU in accordance with document ETR132, a copy of this is available at http://www.aareff.com/ETR132.pdf

ANTENNA

Incorrect antenna can cause RF burns and levels of RF exposure above the recommended limits for personnel

Under NO CIRCUMSTANCES should the antenna be mounted and used at ground level or within a few meters of personnel.

A tuned antenna with the 50 ohm coaxial cable should be used. This should give a return loss ideally of 16dB (SWR 1.4) or better at the operating frequency. The RF plug should be PL259 (UHF) or N type, depending which is fitted to the FM transmitter.

Ensure that all antenna connections are sound, this is important as poor connections and soldered joints can cause RF burns to personnel, severe noise to the transmission and excessive RF bandwidth. Do NOT connect the antenna to the transmitter yet.

Ideally the antenna for this transmitter should be ideally mounted 20 meters high and clear of any surrounding objects to get maximum range and more importantly to reduce risk of radio frequency radiation to personnel. When mounted at 20 meters in height off ground and using 100 watts of transmitter power, power flux density measurements made at ground level directly under the antennas described above show less than 1 W/m2. Several European countries use a value for the power flux density of 10 W/m2 as a basis for considering whether or not an area is safe. The issue of radio frequency radiation limits is a contentious one and work in this field is continuing worldwide.

INSTALLING THE TRANSMITTER

A) Antenna

The previous section, ANTENNA is very important, check this has been done. It is self explanatory from the rear panel where the AC power cord is plugged in.

DO NOT plug in the power cord at this stage. Do NOT connect the transmitter to the power cord or the antenna yet.

B) Bottom Panel Controls

Turn the transmitter upside to locate the:

BE CAREFUL not to be too heavy handed, these controls are only small pcb mounted pots and switches and can be damaged with excessive force. You will need to use a small electrical screwdriver to adjust these controls.

C) FIRST !! Set the RF Output to Zero

Adjust VR2 RF PWR. ADJ fully clockwise, NOT anti-clockwise. In this fully clockwise position the transmitter output is at maximum attention, basically it has no RF output, it is reduced to zero.

D) Setting the Frequency

Locate the two banks of 6 way dip switches S2 and S1. At the very end of this user manual you can locate the section DIL SWITCH (S2 and S1). This table shows all the frequencies from 87.5 to 108 MHz and the corresponding DIP switch settings. Look up your frequency in the table and then set the tiny dip switches to the ON or OFF position as shown in the table. These switches will determine the start up frequency for the transmitter, so, it's very important they are correct. If they are not correct it's possible to transmit on an unauthorised frequency

Double check again with the table in the Annex that the dip switches are in the correct positions. Make sure they are pushed fully into the ON position or OFF position, not halfway between.

E) Powering the Transmitter

Double check the power is reduced to minimum as described in c) above. At this point the antenna should still be disconnected. Connect the Power Cord to the AC. Select FWD on the front panel switch. Observe the front panel Power Meter. The Power Meter should show zero. If it is not zero, disconnect the AC immediately and double check the power is reduced to minimum as described in c) above.

The Power Meter should light up RED, this may change to BLUE after a few seconds, if it does great, if it doesn't, don't worry at this point, this is also normal.

F) Locking the PLL

It may be by chance that the PLL is close to lock and the Power Meter has lit up in BLUE. If this is not the case and the Power Meter is lit up in RED, then adjust in any direction VC1 FREQ. ADJ. slowly,

PLEASE be careful, this control is delicate. Be patient and continue to turn slowly until the meter lights up BLUE, then STOP turning. The BLUE light indicates PLL lock. The Power Meter should continue to indicate zero, if the Power Meter is showing anything above ZERO, remove the AC and please check again paragraph c) Reducing The RF Output To Zero

G) Connecting the Audio / Baseband

There are three variations of this transmitter, 1: The MPX version; 2: The Stereo version and; 3: The Stereo with Audio Limiting and Processing version.

MPX Version

On the MPX version there is just one audio input on the back panel. This is a wide band (30Hz to 76KHz) audio input designed for external processors, stereo and RDS generators

All Stereo Versions

The stereo versions with and without audio processing have the MPX loop IN and OUT on the back panel. For normal operation the MPX OUT needs connecting to the MPX IN with the supplied gold plated RCA/Phono to RCA/Phono cable, like shown in the bottom picture.

This basically connects the internal stereo coder into the MPX input.

If you wish to use an external audio processor or RDS unit that can be inserted in the MPX line between MPX OUT and MPX IN.

) Checking the Audio Deviation

During manufacture and test the audio deviation will be set broadcast standard line of +8dBu peak for +/-75KHz peak deviation at 88.0 MHz. There is a high possibility that this will not be the same level as the audio source feed from your studio, external audio limiter and/or processing device, MPX stereo generator and/or RDS generator. You need to check this as excessive deviation can cause adjacent channel interference to other users of the radio spectrum.

WITHOUT TEST EQUIPMENT

Audio deviation is difficult to measure without proper test equipment and the method described here cannot replace proper test equipment, however if your regulator permits this method it is possible to check the deviation very close to correct level by using a relative comparison. Use a radio receiver tuned to a known high quality, high budget and reputed radio station. For example in the United Kingdom this would be a national BBC station. Feed the audio output of the radio receiver into some VU meter or level indication on a mixer or other audio equipment. Look carefully at the metering level peaks. You will notice the meter peak constantly at a specific level, make a note of this. Place the antenna of radio receiver as close as possible to your transmitter enclosure. Re-tune the radio receiver to your transmitter frequency. Look at the metering again. Adjust VR1 DEV. ADJ. so that your audio constantly peaks at a little lower than the level you noted. When you have achieved this your deviation is a little lower or close to the legal level. The reason for this setting is that it is legal to under deviate, but not-legal to over deviate, with a lack of test equipment

It is better to be under deviating in order to prevent adjacent channel interference until you have proper test equipment available.

WITH TEST EQUIPMENT

Connect the transmitter via a coupler and dummy load to a Spectrum Analyzer, Modulation Analyzer or Deviation Meter. Adjust VR2 RF PWR. ADJ fully ANTI-clockwise. Adjust VR1 DEV. ADJ. for the correct deviation on the test equipment.

I) Connecting The Antenna

Do NOT connect antenna to the transmitter until you have followed all the previous instructions in this section fully.

The Power Meter should be showing zero, if not section c) above Reducing The RF Output To Zero.

If the Power Meter is showing zero, then plug the antenna cable into the transmitter large SO239 or N type connector. Make sure this tight as poor and loose connections can cause RF burns to personnel, severe noise to the transmission and excessive RF bandwidth.

J) Setting the Power

Locate the power control VR2 RF PWR. ADJ. If you followed the previous paragraphs, this power control should be in the fully clockwise. In the fully ANTI-clockwise position the transmitter output is at minimum attention, which means the RF Output is at maximum. Check the switch on the front panel is set to FWD. Adjust this control to the desired power level. THE TRANSMITTER IS NOW ON AIR!

OPERATION

A) Normal Conditions

You should hear the cooling fan. The fan draws air into the front and exits the warm air through the rear vents. It is important to keep these vents clear. If you cannot hear the fan turning, then shut the amplifier down by removing the AC mains immediately. The front meter should illuminate in BLUE

B) FWD and REF Switch

The front panel meter should show 100W when the switch is selected to FWD. This is power being sent out of the output socket to the antenna. When REF is selected the power reading ideally should be less than 10W, this means that only 10W or less is being reflected back from the antenna, this is an acceptable and a normal amount. If the power reading is higher than 20W the antenna may need tuning or there may be a problem with the antenna feeder cable or plugs. If the reading is higher than 25W then there is a serious problem with the antenna and you should shut down the power amplifier and investigate the antenna cables, connectors and installation for problems.

MAINTENANCE

The only maintenance the amplifier needs is some periodic cleaning. Following a number of weeks of continuous 24/7 use (specified below), the transmitter should be shut down and disconnected. A technician or engineer needs to take of the top lid by removing the self tapper screws. Using a soft new and clean paint brush with a vacuum clean hose, the dust should be gently brushed and sucked away from all areas inside. Pay particular attention to the actual fans at the rear and the fan vent at front.

The table below shows the recommended number of weeks cleaning should be done for some typical environmental areas.
