November 27, 2002 Federal Communications Commission Equipment Authorization Division, Applications Processing Branch 7435 Oakland Mills Road Columbia, MD 21046 RE) FCC ID: BRWXR2i To whom it may concern; Please refer to the additional information listed below while reviewing the BRWXR2i System. 1) Section 95.645 (b) states that plug-in crystals must not be accessible to the user. Indicate whether or not crystals are accessible to the user. Although the transmitter crystal is visible from the back of the transmitter, each crystal is glued in place prior to shipment making it a permanent installation. Consumer removal of the crystal will normally result in damage to the crystal. Therefore, frequency changes are done at the service center only. 2) The Manual must contain warnings per section 95.653 A) Please refer to the manual attachment for this information B) All content for operation is contained in the instruction manual. 1) All instructions are contained in the instruction manual. 2) There are no adjustments accessible to the user that would be in violation with the FCC rules. 3) This section is not applicable to our use. If there is any further information required, please contact me directly at: Horizon Hobby Distributors ATTN: Len Sabato Fax: 217-355-0058 Phone: 217-403-3588 [email protected]

This Transmitter is a part of the HORIZON HOBBY DISTRIBUTORS, INC. AM"family" of Remote Control Transmitters which at this time consists of: Transmitter Model # FCC ID # Beat GEAR NET-102 BRWNET102 XR2i NET-112 BRWNET-112 PYTHON BRWPYTHON Separate Applications for each transmitters and for the receivers are submitted as required by the Commission. The Manufacturer, Japan Remote Control Company (JR), manufactures all transmitters and receivers. The AM family of R/C systems is exported by JR to the United States of America, and several European and Asian Countries. The Applicant for this Equipment Authorization, HORIZON HOBBY DISTRIBUTORS, INC. will, following receipt of Grant of Equipment Authorization, import only those versions of these R/C radios which are allowed for use in the USA under the Rules and Regulations of the Federal Communications. The 75 - 76 MHz version of this transmitter is the subject of this Application; these are the units which will be offered for sale to the general public. Page 3 Technical Report Transmitter Model XR2i FCC ID# BRWXR2i 1.2 Application The Model XR2i R/C transmitter utilizes "Amplitude Modulation" to convey the PPM encoded position of its control handle and trigger and switches to its companion R/C receiver, where the PPM encoded pulse train is demodulated, decoded, and supplied to a number of servo-mechanisms for positioning of control surfaces, throttle etc. on the model. Both transmitter and receiver are very narrow band units; they have been designed to comply with the European requirements of 10 KHz channel spacing. 1.3 Construction The Model XR2i Transmitter all consists of a plastic case. (Reference is made to Fig. 5.1, Transmitter Block Diagram) * control handle and trigger * a 8cells dry battery * an analog-to-digital converter (ADC) * a microprocessor to create the PPM pulse train (M38C24M4) * a modulator driver stage * a RF power stage * a telescopic antenna This Transmitter is to be made available by the importer only on those carrier frequencies in the 75 - 76 MHz frequency band which are at present authorized for R/C use. Page 4 Technical Report Transmitter Model XR2i FCC ID# BRWXR2i 2.0 ENCODER THEORY OF OPERATION Reference is made to Figure 5.1, Transmitter Block Diagram. The functions of the encoder are to: * accept the analog voltages from the control inputs (handle and trigger). * process the analog voltages to create control mixing, adding, reversing, etc., as desired by the user. * sample these voltages in a cyclic rhythm under control of the system's internal timing generator. (This process is called commutation.) * process these analog voltages into binary weighted digital control words by means of an Analog-to-Digital Converter (ADC). * store these digital representations of the analog control input into a temporary memory (RAM). * supply this serial data stream to a buffer-driver for modulation of the RF Transmitter. * provide "housekeeping" of the encoding process by means of a quarts crystal controlled internal clock. * provide supply voltages to the RF section (Vcc = 12V battery voltage ; Vreg = 6.0V regulated voltage ). The entire program which controls the timing housekeeping, parallel-to-serial conversion process, and insertion of synchronization words and error detection codes is governed by a Central Processing Unit (CPU) under control by an internally stored program residing in Read-Only Memory (ROM). The CPU, RAM and ROM are all part of a single-chip microprocessor. Resolution of the Analog-to-Digital conversion process is nine (9) bits for a control accuracy of 1:2 9 Page 5 Technical Report Transmitter Model XR2i FCC ID# BRWXR2i 3.0 THEORY OF OPERATION 3.1 General Reference is made to Figure 5.1, Transmitter Block Diagram. The HORIZON HOBBY DISTRIBUTORS, INC. Model XR2i R/C Transmitter is handle and trigger type Transmitter. It operates on any of the R/C frequency (Channels) allowed by the Commission in the 75 -76 MHz frequency band. Selection of the desired RF channel is made by Quarts crystal. 3.2 Block Diagram (Reference is made to Figure 5.1) The (up to) four control potentiometers are at the right side of the schematic drawing. The control potentiometer, which is mechanically coupled to the control handle and trigger, is supplied with the regulated 5.0V voltage. The wiper on this pot is exactly centered in the neutral control handle and trigger position. All analog processing is performed as deviations from this center (reference) voltage. After the mixing of each channel, control voltage is changed to Pulse Train, through encoder circuit. The oscillation is oscillated by Transister Q205 with Third-over-tone, 37.5 MHz then, is dubled by Dobrer Amp. And Transister Q202 and Q203 on 2nd stage to reach 75 MHz. After this, it is amplified by power Amp. Transister Q208, and is supplied to the antenna through band pass filter. Page 6 Technical Report Transmitter Model XR2i FCC ID# BRWXR2i 4.0 FAILURE ANALYSIS A failure analysis was conducted to ascertain that single-component failure will not result in unauthorized radiation. It should be noted that component failure would result in return of the unit to the factory, or to an authorized repair station. (Reference is made to Figure 5.2…
