DOCUMENT CONTROL NOTE VHF 30W Power Amplifi er Instruction Manual IM71-AMP3150-30 iii RF Exposure Warning Exposure to radio frequency (RF) energy has been identifi ed as a potential environmental factor that must be considered before a radio transmitter can be authorized or licensed. The FCC has therefore developed maximum permissible exposure (MPE) limits for fi eld strength and power density, listed in FCC 47 CFR § 1.1310. The FCC has furthermore determined that determination of compliance with these exposure limits, and preparation of an Environmental Assessment (EA) if the limits are exceeded, is necessary only for facilities, operations and transmitters that fall into certain risk categories, listed in FCC 47 CFR § 1.1307 (b), Table 1. All other facilities, operations and transmitters are categorically excluded from making such studies or preparing an EA, except as indicated in FCC 47 CFR §§ 1.1307 (c) and (d). Revised FCC OET Bulletin 65 (Edition 97-01) provides assistance in determining whether a proposed or existing transmitting facility, operation or device complies with RF exposure limits. In accordance with OET Bulletin 65 and FCC 47 CFR § 1.1307 (b), this Daniels Electronics Ltd. transmitter is categorically excluded from routine evaluation or preparing an EA for RF emissions and this exclusion is suffi cient basis for assuming compliance with FCC MPE limits. This exclusion is subject to the limits specifi ed in FCC 47 CFR §§ 1.1307 (b) and 1.1310. Daniels Electronics Ltd. has no reason to believe that this excluded transmitter encompasses exceptional characteristics that could cause non-compliance. Notes: • The FCC’s exposure guidelines constitute exposure limits, not emission limits. They are relevant to locations that are accessible to workers or members of the public. Such access can be restricted or controlled by appropriate means (i.e. fences, warning signs, etc.). • The FCC’s limits apply cumulatively to all sources of RF emissions affecting a given site. Sites exceeding these limits are subject to an EA and must provide test reports indicating compliance. RF Safety Guidelines and Information Base and Repeater radio transmitters are designed to generate and radiate RF energy by means of an external antenna, typically mounted at a signifi cant height above ground to provide adequate signal coverage. The following antenna installation guidelines are extracted from Appendix A to OET Bulletin 65 and must be adhered to in order to ensure RF exposure compliance: Non-building-mounted Antennas: Height above ground level to lowest point of antenna ≥ 10 m or Power ≤ 1000W ERP (1640 W EIRP) Building-mounted Antennas: Power ≤ 1000 W ERP (1640 W EIRP) The following RF Safety Guidelines should be observed when working in or around transmitter sites: • Do not work on or around any transmitting antenna while RF power is applied. • Before working on an antenna, disable the appropriate transmitter and ensure a “DO NOT USE” or similar sign is placed on or near the PTT or key-up control. • Assume all antennas are active unless specifi cally indicated otherwise. • Never operate a transmitter with the cover removed. • Ensure all personnel entering a transmitter site have electromagnetic energy awareness training. For more information on RF energy exposure and compliance, please refer to the following: 1) FCC Code of Regulations; 47 CFR §§ 1.1307 and 1.1310. 2) FCC OET Bulletin 65, Edition 97-01, “Evaluating Compliance with FCC Guidelines for Human Exposure to Radiofrequency Electromagnetic Fields”. 3) http://www.fcc.gov/oet/rfsafety / VHF 30W Power Amplifi er Instruction Manual IM71-AMP3150-30 v Contents General Information ...............................................................1 Introduction ................................................................................................1 Performance Specifi cations .......................................................................2 Physical Specifi cations ..............................................................................3 Theory of Operation ...............................................................5 General ......................................................................................................5 Amplifi er PCB Circuitry ..............................................................................5 Control PCB Circuitry .................................................................................6 Alignment & Installation .........................................................9 Recommended Test Equipment .................................................................9 Amplifi er Board Alignment.......................................…

VHF 30W Power Amplifi er Instruction Manual IM71-AMP3150-30 9 ALIGNMENT & INSTALLATION RECOMMENDED TEST EQUIPMENT Daniels Subrack SR-39-1 with System Monitor Daniels Extender Card Kit EC-48RK Power Supply Regulated 13.8VDC @ 10A Current Meter 5.0A DC Voltmeter RF Coupler (eg. Bird 4275) Wattmeter (eg. Bird 4421) VSWR Meter (eg. Bird 4421) Dummy Loads 50 Ohm, 3:1 (50W) Spectrum Analyzer (eg. IFR 2975) VHF 30W Power Amplifi er Instruction Manual IM71-AMP3150-30 Alignment & Installation 10 AMPLIFIER BOARD ALIGNMENT Refer to the VHF 30W Power Amplifi er Board Component Layout Diagram for the location of the adjustment capacitors, potentiometers, air- core coils and test points. This procedure assumes the use of a single subrack with an EC-48RK extender card kit for both the exciter and the power amplifi er such that their internal adjustment points are easily accessible. Step 1: Remove the top extrusion cover from the transmitter exciter. Set the exciter frequency to either 143MHz or 162MHz depending upon whether you are tuning a lowband or highband unit, respectively. Step 2: Install one of the extender cards in the designated location for the exciter within the subrack. Connect the exciter to this extender card using the gray connector cable provided with the extender card kit. Step 3: Refer to the ‘VHF 30W Power Amplifi er Exploded View’ on page 15 for help on the following procedures. Remove the power amplifi er 14HP case. Next, unplug the cooling fan from the control board and remove the front panel. Using suitable male connectors or a test jig, apply the following signals directly to the amplifi er board: • 13.8V : J3 - Pin1, Pin 2 Note: Ensure an ammeter is connected in series with this line. • Gnd : J3 - Pin 3, Pin 4 • 9.5V : J4 - Pin 4 • Gnd : J4 - Pin 8 (RF Input Sample) Step 4: While monitoring the current on the 13.8V line and without an RF input to the power amplifi er, slowly adjust the potentiometer RV1 until the current reads 230mA. As a check, measure the voltage at TP1. It should read between 2.5V and 3.0V. Step 5: Now connect the output of the exciter to the input of the power amplifi er. Connect the output of the power amplifi er through a suitable RF coupler then through a power meter and fi nally terminate the output with a 50 Ohm load. The low power output from the RF coupler should be connected to the input of a spectrum analyzer. The spectrum analyzer should have an output tracking generator capable of putting out at least a +6dBm signal. This output should be connected to the input of the exciter amplifi er which is fi rst disconnected from the exciter’s local oscillator. Step 6: Before enabling the tracking generator, the output power of the exciter amplifi er should be disabled by turning its potentiometer fully counterclockwise (~12 Turns). Now turn the exciter on by setting the front panel switch to ‘Key Tx’. Set the center frequency on the spectrum analyzer to the same frequency the exciter was set to in Step 1. Next, set the span to 0 Hz and enable the tracking generator with a +6dBm output. Step 7: While monitoring the output on the power meter and ensuring 13.8V on the PA amplifi er board, slowly increase the exciter amplifi er output until 30W is reached. Increase the span on the spectrum analyzer to 20MHz. Next, remove the cover on the low-pass fi lter shield (10601-01) on the amplifi er PCB to allow access to the air-core inductors, L5 to L8. Monitoring the output response on the spectrum analyzer, tune these inductors by altering the spacing between the windings with a plastic adjusting tool for maximum fl atness and gain across the desired band (136 - 150MHz for lowband, 150 - 174MHz for highband). Then capacitor C12 should be adjusted for maximum fl atness and gain also. Step 8: Set the span on the spectrum analyzer to 0 Hz and check that output VSWR is below 1.20 on the band edges and the center frequency of the band. Step 9: As a fi nal check, replace the low-pass fi lter shield and using the spectrum analyzer again, search the band (either 136 - 150MHz or 150 - 174 MHz) for any unwanted spurious emissions. VHF 30W Power Amplifi er Instruction Manual IM71-AMP3150-30 Alignment & Installation 11 CONTROL BOARD ALIGNMENT Refer to the VHF 30W Power Amplifi er Control Board Component Layout Diagram for the location of the adjustment potentiometers and test points. This procedure assumes the use of 1/2 wavelength RF output cables between all pieces of test equipment after the PA output for accurate power readings during mismatched load conditions. Step 1: Once the amplifi er board alignment is complete, the exciter can be turned off and its amplifi er re-connected to the local oscillator. Next, the male connectors or test jig can be removed from the amplifi er board and the control board along with the front panel can be re-connected to the power amplifi er. The power amplifi er can then be connected via the gray cable to the second extender card which should be installed in the designated location within the subrack for the power amplifi er. Step 2: With the exciter’s output still connected to the input of the power amplifi er and the output of the power amplifi er still connected through an RF coupler into a wattmeter and 50 Ohm load, set the transmitter to the desired frequency. Next, adjust the output power of the exciter such that the PA output is 10W. Then adjust potentiometer RV1 until LED1, or the ‘RF POWER’ indicator, just turns on. This threshold may be adjusted to any RF output power level between 10W and 30W. Step 3: Set the exciter output power such that the output power from the PA is equal to that under normal operating conditions. Replace the 50 Ohm load with a suitably rated 3:1 mismatched load. Adjust potentiometer RV2 until LED2, or the ‘HIGH VSWR’ indicator, just turns on. Step 4: As a check, terminate the power amplifi er once again with a 50 Ohm load and ensure that LED2 is now off. If it is not off, adjust RV2 until LED2 just turns of…

VHF 30W Power Amplifi er Instruction Manual IM71-AMP3150-30 iii RF Exposure Warning Exposure to radio frequency (RF) energy has been identifi ed as a potential environmental factor that must be considered before a radio transmitter can be authorized or licensed. The FCC has therefore developed maximum permissible exposure (MPE) limits for fi eld strength and power density, listed in FCC 47 CFR § 1.1310. The FCC has furthermore determined that determination of compliance with these exposure limits, and preparation of an Environmental Assessment (EA) if the limits are exceeded, is necessary only for facilities, operations and transmitters that fall into certain risk categories, listed in FCC 47 CFR § 1.1307 (b), Table 1. All other facilities, operations and transmitters are categorically excluded from making such studies or preparing an EA, except as indicated in FCC 47 CFR §§ 1.1307 (c) and (d). Revised FCC OET Bulletin 65 (Edition 97-01) provides assistance in determining whether a proposed or existing transmitting facility, operation or device complies with RF exposure limits. In accordance with OET Bulletin 65 and FCC 47 CFR § 1.1307 (b), this Daniels Electronics Ltd. transmitter is categorically excluded from routine evaluation or preparing an EA for RF emissions and this exclusion is suffi cient basis for assuming compliance with FCC MPE limits. This exclusion is subject to the limits specifi ed in FCC 47 CFR §§ 1.1307 (b) and 1.1310. Daniels Electronics Ltd. has no reason to believe that this excluded transmitter encompasses exceptional characteristics that could cause non-compliance. Notes: • The FCC’s exposure guidelines constitute exposure limits, not emission limits. They are relevant to locations that are accessible to workers or members of the public. Such access can be restricted or controlled by appropriate means (i.e. fences, warning signs, etc.). • The FCC’s limits apply cumulatively to all sources of RF emissions affecting a given site. Sites exceeding these limits are subject to an EA and must provide test reports indicating compliance. RF Safety Guidelines and Information Base and Repeater radio transmitters are designed to generate and radiate RF energy by means of an external antenna, typically mounted at a signifi cant height above ground to provide adequate signal coverage. The following antenna installation guidelines are extracted from Appendix A to OET Bulletin 65 and must be adhered to in order to ensure RF exposure compliance: Non-building-mounted Antennas: Height above ground level to lowest point of antenna ≥ 10 m or Power ≤ 1000W ERP (1640 W EIRP) Building-mounted Antennas: Power ≤ 1000 W ERP (1640 W EIRP) The following RF Safety Guidelines should be observed when working in or around transmitter sites: • Do not work on or around any transmitting antenna while RF power is applied. • Before working on an antenna, disable the appropriate transmitter and ensure a “DO NOT USE” or similar sign is placed on or near the PTT or key-up control. • Assume all antennas are active unless specifi cally indicated otherwise. • Never operate a transmitter with the cover removed. • Ensure all personnel entering a transmitter site have electromagnetic energy awareness training. For more information on RF energy exposure and compliance, please refer to the following: 1) FCC Code of Regulations; 47 CFR §§ 1.1307 and 1.1310. 2) FCC OET Bulletin 65, Edition 97-01, “Evaluating Compliance with FCC Guidelines for Human Exposure to Radiofrequency Electromagnetic Fields”. 3) http://www.fcc.gov/oet/rfsafety /
