RF Exposure WarningExposure to radio frequency (RF) energy has been identified as a potential environmental factor that must be considered before a radio transmitter can be authorized or licensed. The FCC and IC have therefore developed maximum permissible exposure (MPE) limits for field strength and power density, listed in FCC 47 CFR § 1.1310 and IC RSS-102 Issue 2 Sect 4. 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) and IC RSS-102 Issue 2 provide assistance in determining whether a proposed or existing transmitting facility, operation or device complies with RF exposure limits. In accordance with OET Bulletin 65, FCC 47 CFR § 1.1307 (b) and RSS-102 Issue Sect 2.5, this Daniels Electronics Ltd. transmitter is categorically excluded from routine evaluation or preparing an EA for RF emissions and this exclusion is sufficient basis for assuming compliance with FCC/IC MPE limits. This exclusion is subject to the limits specified in FCC 47 CFR §§ 1.1307 (b), 1.1310 and IC RSS-102 Issue 2 Sect 4. Daniels Electronics Ltd. has no reason to believe that this excluded transmitter encompasses exceptional characteristics that could cause non-compliance.

Notes:

• The FCC and IC’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 and IC’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 InformationBase and Repeater radio transmitters are designed to generate and radiate RF energy by means of an external antenna, typically mounted at a significant height above ground to provide adequate signal coverage. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (EIRP) is not more than that permitted for successful communication. The following antenna installation guidelines are extracted from Appendix A from 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 ≤ 1000 W 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 specifically 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/ 4.

GEnERal InFoRmatIon

SyStEm REGulatoR / PoWER SuPPlyThe System Regulator (SM-3) is a plug-in module – a component of the MT-3 or MT-4E Radio System that provides voltage regulation, system metering and audio monitoring.

The SM-3’s compact 14HP form factor permits use with an optional second control card in the subrack. By enclosing the electronics in a 21-HP case, the extra space can be used for options such as antenna relay(s) and built-in meters.

The System Regulator / Power Supply Module includes the following features:

• A high-current voltage regulator (+9.5 VDC) with an anti-latchup hysteresis circuit.

• Front panel switch-selectable multimeter jacks – to check power supply voltages and carrier strengths.

• An audio amplifier for internal and external speaker options.

• Relay drivers – for optional antenna relay.

thEoRy oF oPERatIon

audIo CIRCuItRyAudio from the receiver modules is applied via B20 (Receiver B audio) and B30 (Receiver A audio) to the front panel rotary switch SW1. Incoming audio is applied through a buffer (U1), then it is applied to the front panel volume control VR1.

U1 provides audio gain (after VR1) to speaker driver U2 to drive the outdoor 8Ω, 1-watt speaker. When mainboard SW2 is ON, the audio LED is activated to indicate additional current is being used at the site by the speaker drivers. Mainboard switch SW1 selects internal and external speakers. The audio circuitry draws approximately 35 mA.



Theory of Operation4

SWItCh FunCtIonS / tESt monItoRAs indicated in the SM-3 specifications, the 12-position rotary switch SW1 monitors several important levels in the subrack. The levels monitored are applied directly to the switch and are terminated at the front panel test jacks (red – positive and black – negative). Any standard 20 kΩ/V meter is capable of monitoring the direct current (DC) test levels.

PoWER SuPPlyUnregulated and regulated DC is connected at input Pins B4 and Z4. CR3 provides a precision voltage reference, which is amplified two times by U1b and then applied to U1a, the voltage regulator error amplifier. R17 is adjusted for +9.5 VDC (± 0.1 VDC) at the output Pins B6 and Z6.

U1a drives Q1, Q8, Q9, and p-channel enhancement mode MOSFETs (metal–oxide–semiconductor field-effect transistors). U1c, Q2 and Q5 perform voltage monitoring of the power supply. U1b and resistor dividers R10, R12 and R14 establish the low voltage trip point (VLTP) at U1c Pin 10.

As the unregulated input voltage decreases the voltage at U1c Pin 9, as set by R1 and R4, input voltage (VIN) approaches that at U1c Pin 10. As soon as VIN is less than VLTP, the output of U1c begins to go positive.

Regenerative feedback is supplied by Q2 turning on and further lowering VIN. Q5 also turns on and clamps the reference input of the voltage regulator error amplifier to ground. This forces the output of U1a close to the positive rail and turns Q1, Q8 and Q9 off. CR7 ensures that the feedback input of the error amplifier is always higher than the reference input to prevent unwanted oscillations.

Hysteresis around the lower trip point is provided by the combination of R4/R5/R6. When Q2 is turned on, VIN is reduced from supply voltage VSUP*R4/(R4+R1) to VSUP*(R4/R5/R6)/R1+(R4/R5/R6). The supply voltage must rise higher than VLTP (typically VUT - VLTP = 3 V) to turn the regulator back on.

SyStEm REGulatoR alIGnmEnt

REPaIR notEThe SM-3 is made up of surface mount devices that should not be removed or replaced using an ordinary soldering iron. Removal and replacement of surface mount components should only be performed using specifically designed surface mount rework and repair stations, complete with Electrostatic Discharge (ESD) protection.

When removing Surface Mount Solder Jumpers, it is recommended to use solder braid in place of manual vacuum-type desoldering tools. This will help prevent damage to the circuit boards.

System Regulator Alignment6

GEnERal FEatuRESThe system regulator is factory calibrated (unless specified otherwise) to the following specifications:

• +9.5 VDC ± 0.1 VDC regulator output @ 25°C

• Hysteresis set to turn off at +9.0 VDC ±0.10 VDC

• Hysteresis set to turn on at +11.0 VDC ±0.10 VDC

For Ground Pins Z30, D32, B32 and Z32:

1. Apply +13.8 VDC to the power input Pins B4 and Z4.

2. Measure the +13.8 VDC output at Pins B2 and Z2 – this voltage varies with the applied voltage.

3. Measure Pins B6 and Z6 – this voltage should be +9.50 VDC, ±0.1 VDC, with no load.

4. Vary the input voltage from +10 to +17 VDC – the output should remain at +9.5 VDC ±0.1 VDC.

5. Connect the 2.3 A load to the +9.5 VDC output – confirm the applied voltage is set to +13.8 VDC.

6. Adjust the input voltage from +10 to +17 VDC and verify the DC regulated +9.5 VDC corresponds to the test sheet provided.

NOTE: Make certain that the ground and power leads running to the regulator are at least 16 AWG wire – to ensure that false voltage drops do not occur.

If the +9.5 VDC output varies from the test sheet do not replace or reset the regulator until hysteresis is confirmed. With the load on, lower the input voltage to less than +9.0 VDC. The +9.5 VDC output (Pins B6 and Z6) should drop to 0 VDC. When the voltage is raised above +11.0 VDC, the +9.5 VDC regulator should reactivate.

With no load on the +9.5 VDC output, the total current consumption should be less than 4 mA at +13.8 VDC. This current is drawn by U1, U2 and the biasing resistor networks.

audIo alIGnmEnt1. Apply a -12 dBm to -8 dBm, 1 kHz audio signal to Pin B30.

2. Select A audio (front panel switch) and verify audio is present at the system regulator loudspeaker.

3. Repeat the above procedure for the B system, with the audio input at Pin B20.

4. Proceed with environmental testing.

ChanGInG hyStERESIS lEvElS1. Determine Turn-Off and Turn-On levels required.

(Factory Norm: Turn-Off < +9.0 VDC and Turn-On > +11.0 VDC)

2. Adjust the select resistor combination R11/R12 with a resistor substitution box for the appropriate lower voltage Turn-Off point.

3. Install the necessary parallel resistances.

4. Adjust the select resistor combination R5/R6 with a resistor substitution box for the upper voltage Turn-On.

5. Confirm the Turn-Off and Turn-On voltages and install the selected values.
