Locally using the front panel controls and indicators Locally using an extended control head Remotely using an M7 series controller Remotely using compatible control equipment. Local Operation Local operation of the M7 is effected from a front panel mounted Control Head (Fig 1-3). The control head contains a high visibility electroluminescent display, tactile soft keys and a numeric keypad. A complete operator audio interface incorporating loudspeaker, headset and microphone facilities is included, along with a USB device interface. Fig 1-3 M7 Control Head Local Operation Using an Extended Control Head The control head is self-contained and connects to the radio via a single E1 link. If required, the control head can be removed from the radios front panel and located up to 10 metres away (see Fig 1-4).

More complex configurations where multiple controllers operate multiple radios are described in the M7 Controller documentation. Remote Operation Using Compatible Control Equipment The radio is operated remotely by connecting compatible control equipment to the rear panel interfaces. All interfaces are detailed in the Installation topic. Waveform Profiles and Frequency Presets M7 radios introduce the concept of Waveform Profiles and Frequency Presets to provide a simple method of configuring the radio for various operational scenarios. Waveform Profiles contain all the settings, except operating frequency, for a particular waveform. At least one profile is assigned to each modulation waveform. Multiple profiles, each having different settings can be assigned as required. Up to twenty waveform profiles can be stored in a radio. Frequency presets consist of a Waveform Profile plus an associated operating frequency. Up to 400 frequency presets can be stored in a radio. Waveform profiles and frequency presets are fully described in the Operation topic. Security Profiles Security profiles control individual operator access to various levels of radio functionality. Each user is allocated one of three security profiles accessed by a 4-digit PIN. Access to specific functions, for example: recalling frequency presets, can be disabled for each profile. Setting security profiles is detailed in the Operation topic. M7X and M7R Page 1-5 Overview Back to Menu Built-In Test The M7 radio has a comprehensive Built-In Test (BIT) system that continuously monitors key parameters and reports status information. Should a fault be detected, the BIT screen indicates the faulty module or component. The BIT system also detects external environmental conditions that could lead to degraded performance of the radio, such as high temperature and high VSWR. The BIT system is described in the Maintenance topic. Power Supply All M7 radios operate from a 99 to 264 Vac mains supply, or a low voltage 24/28 Vdc supply. When both ac and dc input supplies are connected, the radio operates from the ac mains. Should the mains supply fail, the radio automatically switches to dc operation and then reverts back to ac operation when the mains supply is restored. M7 Construction All M7 radios utilize a common stainless steel chassis assembly that incorporates an ac/dc power supply and an interconnection system. The design incorporates provision for telescopic slide mounting in industrial standard 19 inch (483 mm) cabinets, and for free-standing applications. Various radio modules are installed into the chassis as required by the chosen configuration. Modules are individually screened to provide maximum EMC immunity. Similar modules are interchangeable and do not require any alignment or manual adjustment on replacement except for an RF power trim or frequency trim. Modules are individually configuration controlled and have electronic serial numbers for simplified logistics. M7X and M7R Page 1-6 Overview Back to Menu Specification Back to Menu General Specification Frequency Range All models operate between 100 and 399.975 MHz (subject to waveform limitations). Pre-Selectable Frequency Bands Four pre-selectable frequency bands are available to limit the radio's user selectable frequencies. Modulation Waveforms All models are capable of multiple modulation waveforms. Different waveforms are available by including the appropriate software fills. Each radio can hold all the software fills simultaneously. Fig 2-1 details the waveforms available.

The factory default is internal. Back to Menu Internal The internal reference frequency is generated by a 10 MHz oscillator having a frequency accuracy better than 0.15 ppm and an adjustment range to allow for 20 years ageing. An output is provided suitable for driving an external frequency counter. External For all waveforms, an external 10 MHz reference frequency can be used instead of the internal reference frequency. Input Supplies The M7X and M7R operate from either an ac mains or a dc input supply. When both supplies are connected, operation from the ac supply takes priority; automatic change-over to the dc supply occurs if the mains supply fails. On restoration of the ac supply, the equipment reverts to ac operation. ac Supply dc Supply Current Overload Standby Any voltage between 99 and 264 Vac, single phase, 48 to 62 Hz. Power consumption figures are shown in Table 2-2. Any voltage between 21.6 and 32 Vdc, negative earth. Power consumption figures are shown in Table 2-2. Separate ac and dc fuses mounted on the rear panel provide protection from current overload. Standby removes power to all the radio circuits, but does not disconnect the ac or dc input circuits from their relative supplies.

+55oC. Storage Temperature Range All models can be stored at temperatures between -40oC and +70oC without damage. Humidity Range Altitude All models operate at relative humidities between 5 and 95%

non-condensing. All models operate at altitudes up to 5000 m and can be transported at altitudes of up to 15000 m without damage. Shock and Vibration All models operate after a shock of 40 g from 45 Hz to 2 kHz. Compliant with EN 60068-2-27. Ingress Ventilation Warm-up Time All models operate during vibrations of 4 to 500 Hz. Compliant with EN 60068-2-6. All models operate in an environment defined in EN 60529 with a freestanding radio to IP20 and the front of the control head to IP34. All radio models have two independent forced-air ventilation systems. The first consists of twin fans (for redundancy) mounted on the rear panel, drawing air in from behind the radio, blowing it unfiltered through a heat sink assembly isolated from the rest of the radio

(cooling the power supply and RF PA) and exhausting it through the front panel. The second consists of a single fan mounted on the rear panel, drawing air in from behind the radio, blowing it unfiltered into the main chassis (cooling the remaining modules) and exhausting it through the front panel. Fans are easily disconnected and removed for replacement. All fans are speed monitored and controlled, dependent on cooling requirements and environmental conditions. All models are fully operational within 20 seconds after switch on, but the radio frequency reference takes up to 10 minutes to meet the frequency accuracy specification.

Fig 3-5 Indications for Transmit, Receive and Guard Operation M7X and M7R Page 3-6 Operation Back to Menu Tuning the Radio Tuning the radio makes it ready to operate using the required waveform, the required settings for the selected waveform, and at the required frequency. There are three methods of tuning the radio:

(1)

(2)

(3) Tuning using the current waveform profile. This involves selecting a new operating frequency while retaining the current operating waveform and radio settings. See page 3-12. Tuning by recalling a stored waveform profile. This involves recalling one of the 20 available waveform profiles and then entering the required operating frequency. Waveform profiles are detailed on page 3-8. Tuning by recalling a stored waveform profile is described on page 3-14. Tuning by recalling a stored frequency preset. This involves recalling one of the 400 available frequency presets that have been stored in the radio. A stored frequency preset contains a Waveform Profile and an operating frequency (or channel if in Maritime mode). Frequency presets are detailed on page 3-9. Tuning by recalling a stored frequency preset is described on page 3-17. Federal Communications Commission (FCC) Regulations This transceiver complies with Part 15 and Part 87 of the FCC rules. Operation is subject to the condition that the transceiver does not cause harmful interference. You are required to obtain a station license before transmitting from your transceiver. This equipment is licensed only for operation in the VHF aeronautical frequency band between 118 and 136.975 MHz using amplitude modulation (AM) and 25 kHz channel spacing. The transceivers power output should not exceed the output necessary for satisfactory technical operation, taking account of local conditions and the area to be covered. The transceivers frequency and parameters should be checked by authorized service personnel before use and yearly (or more frequently) thereafter. M7X and M7R Page 3-7 Operation Back to Menu Waveform Profiles A waveform profile is a set of instructions stored in the radio that define a mode of operation and certain parameters associated with the mode. Up to 20 waveform profiles can be created and stored in the radio. When a waveform profile is recalled, the user is prompted to enter an operating frequency (or a channel number if in Maritime mode). Fig 3-6 and Fig 3-7 show example waveform profiles. The default waveform profile designations are WP1 to WP20. When created and stored in the radio, the designation can be changed to any name containing up to eight characters. The waveform profile WP6 illustrated in Fig 3-6 could be renamed, for example, AMV30W (signifying AM voice with a 30 watt output).

Some configuration settings must be correctly set to match the physical installation; for example, the polarities of the PTT signals and whether a transceiver has been configured as a transceiver, transmitter or receiver. For this reason it is recommended that the security facility be applied before the radio is put into operational use. Restricting an operator from changing configuration settings will avoid inadvertent editing. After the configuration has been completed, Waveform Profiles and Frequency Presets should be created and stored. The procedure to create and store a Waveform Profile is given on page 3-32; the procedure to create and store a Frequency Preset is given on page 3-36. Finally and if required, security should be applied. This is detailed on page 3-40. M7X and M7R Page 3-22 Operation Radio Configuration Procedure To configure the radio settings:

WARNING Dangerous Voltage A mains isolating switch should be fitted close to, and easily accessible from, the radio's position. The isolation switch should isolate both live and neutral supplies, be clearly labelled, and adequately rated to protect the equipment. WARNING Beryllium Hazard Four semiconductor devices used in the RF PA contain the toxic material beryllium. Although no procedures in this documentation instruct semiconductor replacement, equipment covers are removed exposing the devices. Users should be aware that there could be a hazard should the output transistors become damaged. Fig 4-1 shows the RF PA; the four semiconductors containing beryllium are outlined and have the markings PAS1068, PAS1074 or PAS1075. Fig 4-1 Beryllium Hazard Components M7X and M7R Page 4-2 Installation Back to Menu WARNING Antenna Radiation The transmit antenna must be installed such that the resultant radiated field strength is below 10 W/m in areas normally accessible to personnel. The RF field strength from the antenna can be predicted from the equation S=1.45PG/4R2

[Where S = power density; P = power input to antenna; G = antenna gain; R = distance to centre of radiation and 1.45 = multiplication factor for average power based on a modulation index of 95%.]

Based on this formula, and using a 2 dBi antenna, the predicted safe distance from the centre of radiation would be approximately 1.3 m for a field strength of 10 W/m2 (1 W/cm2). This meets the requirements of Health Canada Safety Code 6 for RF and microwave exposed workers. For persons not classed as RF and microwave workers, and including the general public, the limit is 2 W/m2 (0.2 mW/cm2) which increases the minimum safe distance to 2.9 m. Further information on calculating the field strengths and power levels can be found in Health Canada Safety Code 6 'Limits of Human Exposure to Radio Frequency Electromagnetic Fields in the Frequency Range 3 Hz to 300 GHz', RSS 102 Radio Frequency Exposure Compliance of Radiocommunication Apparatus (All Frequency Bands) and also in FCC document OET Bulletin 5. Caution ESDs The M7 radio contains Electrostatic Sensitive Devices (ESDs). Personnel must be aware of the precautions necessary to prevent damage to such devices. During installation all precautions necessary to prevent ESD damage must be taken. Caution Unauthorized Modifications Changes or modifications made to this equipment that are not expressly approved by Park Air, or parties authorized by Park Air, could void the users authority to operate the equipment.

This stud is used to connect the radio to the equipment cabinet, or to the user's system earth point. The stud must not be used as the safety earth. In order not to compromise the radios Electromagnetic Compatibility (EMC) the chassis stud, marked and fitted to the rear panel (see Fig 4-4 on page 4-6) must be connected to the equipment cabinet

(if a cabinet is being used) or to the user's system earth point. The connection should be made using a single tri-rated, green-and-yellow cable having a cross-sectional area of 2.5 mm2. The cable should have CSA and UL1015 approval, and be connected to the chassis stud through an M5 eyelet (for example, Park Air part number 20-08010103). Failure to comply with this instruction could result in non-compliance with the European Commission EMC Directive 89/336/EEC. Connecting the Input Supply The M7 radio operates from a standard ac mains supply, or a low voltage dc supply; the specification for the ac and dc supplies is given in topic 2 Specification.

The pin-out is listed in Table 4-7. The connector has an integral amber indicator that lights when the PTT input is active. Note:

All line levels for this connector are equivalent to the average speech level regardless of the waveform selected. The peak to average ratio of speech is taken to be 13 dB, whereas the peak to average ratio of a sine wave is 3 dB. Therefore, sine wave test tones are expected to be 10 dB higher than line level setting. An average speech signal applied at the same level as the line in setting (or a sine wave signal applied at 10 dB above the line in setting) with the ALC off, will result in the transmitter achieving its specified modulation level. Similarly, receiving a signal at the same modulation level as the transmitter specified level, with the audio AGC off, will result in an average speech signal being the same level as the line out setting (or a sine wave signal being 10 dB above the line out setting).

M7X and M7R Page 5-2 Maintenance Back to Menu Scheduled Maintenance Park Air recommends that scheduled maintenance be carried out at twelve-monthly intervals. If the radio is operated in harsh conditions, scheduled maintenance may be required more frequently. Scheduled maintenance comprises the following actions:

Number Action Tools/Test Equipment Required 1 2 3 Ensure the radio is clean and that external connectors are securely fitted. Check the radios internal frequency reference. Adjust as required. Perform an ac and dc change-over check (if both input supplies are connected to the radio). Camel hair brush. Clean lint-free cloths. Frequency counter able to measure 10 MHz. Cleaning and Checking Security of Connectors

Remove any dust and dirt from the radios exterior surfaces using a lint-free cloth and camel hair brush. Take particular care when cleaning the display: dust should be removed using the camel hair brush. Any marks that remain after brushing should be removed by gently wiping with a very lightly dampened clean lint-free cloth. Do not use a dirty cloth to wipe the display; any grit particles may scratch the display screen. Ensure that all external connectors are secure and free from damage. M7X and M7R Page 5-3 Maintenance Back to Menu Checking the Internal Frequency Reference The radio can operate from an internal frequency reference, or from an external frequency reference connected to the rear panel 10 MHz connector. To set the radios internal frequency reference, use the following procedure.

(1) Connect a frequency counter to the front panel 10 MHz Reference Frequency Out connector;

(8) Press Key 5 Home.

(9) Disconnect the frequency counter. Checking the ac and dc Change-Over When both an ac and a dc input supply are connected to the radio, operation is normally from the ac mains supply. Should the mains supply fail, operation automatically switches to the dc supply without any interruption to service. If both ac and dc input supplies are connected to the radio, carry out the following check:

(1) Confirm that both ac and dc supplies are connected to the radio. Ensure that the rear panel ac and dc power switches are set to the I (on) position.

(2) Confirm that the front panel ac and dc indicators are lit, the display is lit, and the radio is operational.

(3) Switch off the ac supply from its source.

(4) Check that the radio continues to operate from the dc supply and the front panel ac indicator is unlit. Note that the BIT indicator flashes when the ac supply is switched off. M7X and M7R Page 5-5 Maintenance Back to Menu Intentionally Blank M7X and M7R Page 5-6 Maintenance

19 September 2007 FAA Spectrum Engineering Division 800 Independence Avenue SW Washington, DC 20591 Dear Mr. Frazier, Please be advised that we shall be making an application to the Federal Communications Commission to obtain an Equipment Authorisation Grant for Park Air Systems new multimode ground based transceiver type M7X under Part 87 rules, in the band 118 MHz to 136.975 MHz. The standard model M7X, provides 50W AM/ 100W FM RF output power operating in the 100-

399.975 MHz band. Employing 25 kHz / 8.33 kHz channel spacing it is intended primarily for military users but the radios are also suitable for civil aeronautical applications. It can be controlled remotely from the M7C Desktop controller via a single E1 data link. For sales within the United States of America and under the proposed FCC filing C8LBM7X, the radios functionality will be firmware limited as follows:

The equipment will provide up to 50W RF output power in the 118 399.975 MHz band. Transmission shall be disabled in the frequency bands 100- 117.975 MHz and 328.6 335.4 MHz. Operation will be limited to amplitude modulation within a 25 kHz channel spacing. 8.33 kHz channel spacing and FM operation are inhibited. Our application to the FCC is being made via an accredited test house, Intertek acting as our Conformity Assessment Body. Testing is scheduled to commence in early November 2007 In accordance with FCC regulation 87.147(d) I would be grateful if you could address any concerns or objections to myself. Yours faithfully, Allan Horsfield Consultant Engineer EMC and Approvals a.horsfield@uk.parkairsystems.com Test House:

The transmitter provides 50W AM / 100W FM carrier power and a separate Guard Receiver module may be included as an option. All operational controls are located on a single front panel containing a screened assembly. This unit can be removed from the radio if local operation is not required and by combining it with a power supply and interface module it forms the basis of the equipments remote controller (M7C). To meet the EMC requirements, a mechanical double-barrier approach has been adopted. All circuits are contained within their own, EMC tight, module case. These modules are then located within the chassis which provides a second level of screening. All radio modules store their serial number, part number and build state in electronic form enabling reporting of this information to the front panel display, remote controller or other system interface. The M7 series supports waveforms for AM Voice, FM Voice, AM Wide, FM Wide, Link11, Maritime and HQ II, plus additional waveforms can be specified. The Electronic Protective Measure (EPM) waveforms (HQ II, Talon and Saturn) are provided by a proprietary bought-in module which is fitted within the radio for licensed military operations. The equipment is available in a number of versions including receive only and transceivers with or without EPM capability. The M7X for which this application is being made is the standard non EPM V/U transceiver with all limitations being performed in firmware to prevent unauthorised use. These limitations are applied at the factory to all units bearing the FCC ID Label. Pictures:
