1 April 2005 FAA Spectrum Engineering Division 800 Independence Avenue SW Washington, DC 20591 Dear Sirs, Please be advised that we are making applications to the Federal Communications Commission to obtain Equipment Authorisation grants for Park Air Systems new range of VHF multimode transmitters and receiver type T6. The models covered are : T6T 50W VHF AM transmitter under filing C8LB6350/S2 T6TR 50W VHF AM transceiver under filing C8LB6550/S2 T6R VHF AM receiver under filing C8LB6100/S2 T6T HS 100 VHF 100W AM transmitter under filing C8LB63100HS The equipment provides upto 50W/100W RF output power in the 118 – 136.975 MHz band employing A3E (AM) modulation. The original versions of of the 50W T6 transmitter and receiver were filed in 2000. The new models have been redesigned to use more common modules and improve compatibility with future digital modes. A summary of the equipment’s performance is attached. Our application to the FCC is being made via TuV Product Service in the UK, acting as our Conformity Assessment Body. If you could address any concerns or objections to myself or TuV I would be grateful. Yours faithfully, Allan Horsfield Principal Engineer EMC and Approvals CAB: TUV Product Service Ltd, Segensworth Road, Fareham, Hampshire PO15 5RH England Attention: Maggie Glasspool [email protected] Park Air Systems Ltd, Northfields, Market Deeping, Peterborough, PE6 8UE, England.

Method of tuning Frequency selected by front panel control and LCD display. Channelling capability 25 kHz (8.33kHz capable). Emission bandwidth Within FCC limits see attached report summary Emission type 6K00A3E Emission/harmonics See attached report summary EMC All products are Type examined under the EMC Directive to comply with emission and immunity requirements to Class B. Certificates attached. Description Park Air Systems T6 series are VHF multi-mode air-traffic control radios compatible with analogue (AM) and digital (D8PSK) modulation modes. Current models are supplied programmed for AM voice operation in the frequency range 118 to 136.975 MHz using 25 kHz or 8.33 kHz channel spacing. The latter is disabled through front panel settings for the American market. The transmitter produces a 50W/100W carrier output that can be reduced, in steps, to 5/10W. The output power, and the majority of operational settings, can be selected at the front panel, using the virtual front panel (VFP) on a pc, or through a compatible control and data system such as the PAE multi-access remote control (MARC) system. A multi-channel feature allows up to 100 frequency channels to be stored and recalled by channel number. The T6R is the complementary receiver utilising the same front panel and processor modules to minimise spares requirements. The equipment is designed to be fitted in an industrial 19 inch (483 mm) equipment rack. Operation is from either a standard ac mains supply, or from a low voltage dc supply. When both input supplies are connected, the dc supply acts as a back-up if the mains supply fails. Comprehensive continuous and interruptive Built-In Tests (BIT) provide confidence of the radios serviceability. All transmitters employ the same processor control module, power amplifiers and power supplies. The T6TR power amplifier is identical to the T6T but has a PIN diode antenna changeover device fitted. The 100W version uses two combined 50W power amplifiers.
