EXPOSITORY STATEMENT
TRANSMITTER DESCRIPTION
The transmitter is a keypad garage door entry system for use with receivers designed by
The Genie Company / GMI Holdings Inc., a wholly owned subsidiary of Overhead Door
Corporation. The transmitter data transmission is a fixed code 10 and 20 Khz data stream
with a 50% duty cycle that is decoded by the receiver. Tables are included to detail data
structure.
The circuit consists of the following:
•
keypad
•
micro-controller with resonator controlled oscillator at 4 MHz
•
encoder
•
RF oscillator (antenna is integral part of the oscillator tank circuit)
•
9 volt battery
When the user enters the proper code sequence, the encoder modulates an RF carrier
which is tuned to a frequency of 390 MHz. See the accompanying schematic and block
diagrams.
The back of the transmitter has a label with the required FCC text, along with the FCC
identifier, B8Q WKF99, and the model number. An accompanying drawing example
detailing the label is provided. The position of the label is shown in the accompanying
photograph.

NOTES ON RADIATED EMISSIONS
B8Q WKF99
Sept 15,1999
1) The
reported meter readings are the highest levels observed of six positions of the DUT
and the antenna for each frequency.
2) The Measurements up to 1Ghz were taken using the HP8447D amplifier. The
measurements above 1Gnhz were taken using the HP 8449B amplifier.
3) The reading of -65 dBm is the lowest measurement possible with the equipment
available. This level is below the allowed limit in each case.
4) Sample calculation: uV/m = 10 (107 + M + AF + CF - G - DC) / 20
M = -28.0
AF = 2.0
CF = 2.0
G = 27.0
DC = 9.0
uV/m = 316
5) The actual duty cycle is a function of the transmitted code. The transmitted data has a
worst case duty cycle of 50%. This gives the -6dB correction factor in the above equation
and in the Radiated Emissions calculations. Using the data times shown in the expository,
the correction factor calculation is as follows:
correction = 20 * log (25usec/50usec) = -6 dB
6) The transmitters were modified to allow continuous transmission.
7) The transmitter was surveyed for emissions resulting from the local oscillators. No
measurable emissions were present.
8) A chart of the data word structure is included figure 1.
9) All measurements were made using ANSI 63.4-1992.
