Timco Engineering Inc. 849 NW State Road 45 Newberry FL 32669 Page 1 of 3 From: Mario de Aranzeta [email protected] To: Stan Lyles [email protected] FCC Application Processing Branch Re: FCC ID PDHGMRS-1200L Applicant: TTI Tech Co., Ltd. Correspondence Reference Number: 23031 731 Confirmation Number: EA751360 1.) You have two power levels for GMRS. How is the power levels control? Please explain. The radio has a High and Low power setting from the menu that allows its selection on GMRS frequencies. On FRS frequencies Low power is the only power that the microprocessor allows. High and low power are accomplished in the circuitry by microprocessor control of a transistor in the RF amplifier stage. 2.) Please provide the dBm power levels on pages 11 and 12 of the radiated spurious emissions measurements. Our test method for the substitution method as described in TIA/EIA 603 (2.2.12) using a dipole for frequencies below 2500MHz. Above 2.5 GHz a double ridged guide antenna was used and referenced back to a dipole. We usually do not keep the raw data in our files just the adjusted to dipole data. In this case we remeasured the EUT and the adjusted signal generator readings were tabulated. I have remeasured the EUT and included this data on page 3 of this reply. 3.) Please resubmit new data for battery end-point. Section 2.1055 (d) (2). Your data looks like plus and minus 15%. A revised temperature stability page is attached as page 2 of this reply. The alignment instructions page has also been updated and uploaded to you. Regards, Mario de Aranzeta, Engineer Timco Engineering Inc. 849 NW State Road 45 Newberry FL 32669 Page 2 of 3 2.1055 Frequency stability: 95.621(b) Temperature and voltage tests were performed to verify that the frequency remains within the 0.00025%, 2.5 ppm specification limit. The test was conducted as follows: The transmitter was placed in the temperature chamber at 25 degrees C and allowed to stabilize for one hour. The transmitter was keyed ON for one minute during which four frequency readings were recorded at 15 second intervals. The worse case number was taken for temperature plotting. The assigned channel frequency was considered to be the reference frequency. The temperature was then reduced to -30 degrees C after which the transmitter was again allowed to stabi- lize for one hour. The transmitter was keyed ON for one minute, and again frequency readings were noted at 15 second intervals The worst case number was recorded for temperature plotting This procedure was repeated in 10 degree increments up to + 50 degrees C. Readings were also taken at the end point of the battery voltage of 6.0 VDC. MEASUREMENT DATA: Assigned Frequency (Ref.

Circuit Composition and Operation Theory The basic explanation for the circuit composition GMRS-1200L consists mainly of the one board controlling the analog circuit parts and the digital circuit parts for the other control. 2. Receiver GMRS-1200L transmission parts is composed in the double conversion system, which has the 1 st IF frequency of double 21.7 MHz and the 2 nd IF frequency of 450 kHz. With the RF fronted which has an excellent band characteristics and skirt characteristics, the 2 pole MCF used in the 1 st IF, and the 3 pole ceramic filter in the 2 nd IF, the reception interrupting factors such as the image and the sensitivity repression are reduced for the more stable reception. 2-1. RF Front-end The signal received by the antenna will be transmitted to the band pass filter through the antenna switching circuit consisted of L16, L17, L18, L19, C95, C96, C97, C98. The front RF amplifier transistor Q1 consists of the L1, C7, C8, R1, R2 input band pass filter and F1 output band pass filter, primarily diminishes the other signal rather than the 1 st IF image and other signal within the reception band and amplifier only the necessary signal within the RF. 2-2. 1 st Mixer The receiver which has been amplifier in the RF front-end is provided to the base of the 1 st mixer Q2. The 1 st L/O signal provide from the VCO is supplied to the emitter of Q2 and Converted to the 1 st IF 21.7 MHz. 2-3. 1 st IF Filter and 1 st IF Amplifier The signal covered by Q2 to 21.7 MHz, the 1 st frequency, change its impedance through C13, L5 and then is infused to the fundamental MCF which has the center frequency of 21.7 MHz and the width of +/- 3.75 KHz. Here, the signal reduces the image and other unwanted signal for the 2 nd IF , and changes its impedance again through the R10. Then the signal is infused to the Q6(1 st IF amplifier part). The signal infused to the Q6 is amplifier approximately by 20 dB in other to acquire the required reception sensitivity, and infused to the Q6 which functions as the 2 nd mixer, the 2 nd IF amplifier, and the FM detector. 2-4. 2 nd Mixer, and IF, FM Detector (Q6) The receiver IF signal of 21.7 MHz, which has been infused to Q6 is mixed with the 2 nd L/O converted to 450 KHz, the 2 nd IF frequency. The receiver signal converted to the 2 nd IF signal frequency passed through the CF1, the ceramic filter of 450 kHz again. After the limiting inside the Q6 and the FM demodulating by the quadrature detector inside the Q6, the signal offers the output through the 26 th pin of Q6. The squelch circuit is composed to detect the noises from the received signal demodulate in the 26 th pin of the Q6. For this purpose, the noise filter is using the OP amplifier inside the Q6. GMRS-1200L 4 2-5. Audio Power Amplifier (Q35) The receiver audio signal, which has been adjusted to the appropriate electrical volume by controlled CPU and Tone IC are supplied to the 3 rd pin of the Q35 and amplified approximately by 20 dB. Then, it turns up the speaker with the maximum output of 0.3 watts. The 7 th pin of Q35 is the audio mute terminal. If a voltage supply to the 7 th pin of the Q35 is from VBTT line supplied to this terminal, the Q35 stops functioning as the audio power amplifier regardless of the signal supplied to the 3 rd pin of the Q35, and there is no sound emitter from the speaker. 3. Transmitter The transmitter parts of the GMRS-1200L is designed to amplify the RF signal oscillated and modulated by the synthesizer to approximately 2W by the power FET of Q19, Q20. 3-1. Pre-emphasis The voice signal input from the microphone is infused to Q6(Mic amplifier part). And The signal is pre-emphasized at the C506, R509. Ther the sigal is MIC amplifierd by Q502A. The signal which comes out of the Q502D is limited to a certain amplitude for the voice signal not to exceed the allowable band width assigned for transmission. 3-2. Tx Power (Q19, Q20) The transmitted signal of, combined at the driver TR is supplied to the gate of the Q19/Q20 amplifier. The transmitted signal amplifier to 2W here passes the …
