FCC §2.1046, §95.567 - RF OUTPUT POWER
Applicable Standard
Acorrding to FCC §95.567

Each FRS transmitter type must be designed such that the effective radiated power (ERP) on channels 8
through 14 does not exceed 0.5 Watts and the ERP on channels 1 through 7 and 15 through 22 does not
exceed 2.0 Watts.


Test Procedure
The transmitter was placed on a wooden turntable, and it was transmitting into a non-radiating load, which
was also placed on the turntable.

The measurement antenna was placed at a distance of 3 meters from the EUT. During the tests, the antenna
height and polarization as well as EUT azimuth were varied in order to identify the maximum level of
emissions from the EUT .The test was performed by placing the EUT on 3-orthogonal axis.

Remove the EUT and replace it with substitution antenna. A signal generator was connected to the
substitution antenna by a non-radiating cable. The absolute levels of the emissions were measured by the
substitution.

EMISSION MASK
Applicable Standard
According to §95.573

Each FRS transmitter type must be designed such that the occupied bandwidth does not exceed 12.5 kHz.

According to §95.579

 Each FRS transmitter type must be designed to satisfy the applicable unwanted emissions limits in this
paragraph.

(a) Attenuation requirements. The power of unwanted emissions must be attenuated below the carrier
power output in Watts (P) by at least:

(1) 25 dB (decibels) in the frequency band 6.25 kHz to 12.5 kHz removed from the channel center
    frequency.

(2) 35 dB in the frequency band 12.5 kHz to 31.25 kHz removed from the channel center frequency.

(3) 43 + 10 log (P) dB in any frequency band removed from the channel center frequency by more than
31.25 kHz.

Note: Emission bandwidth was based on calculation method instead of measurement.

Emission Designator

Per CFR 47 §2.201& §2.202, BW = 2M + 2D

For FM Mode (Channel Spacing: 12.5 kHz)
Emission Designator 11K0F3E
In this case, the maximum modulating frequency is 3.0 kHz with a 2.5 kHz deviation.
BW = 2(M+D) = 2*(3.0 kHz + 2.5 kHz) = 11 kHz = 11K0
F3E portion of the designator represents an FM voice transmission
Therefore, the entire designator for 12.5 kHz channel spacing FM mode is 11K0F3E.

FCC §2.1053 & §95.579 - RADIATED SPURIOUS EMISSION
Applicable Standard
FCC §2.1053 and §95.579


Test Procedure
The transmitter was placed on a wooden turntable, and it was transmitting into a non-radiating load, which
was also placed on the turntable.

The measurement antenna was placed at a distance of 3 meters from the EUT. During the tests, the antenna
height and polarization as well as EUT azimuth were varied in order to identify the maximum level of
emissions from the EUT .The test was performed by placing the EUT on 3-orthogonal axis.

The frequency range up to tenth harmonic of the fundamental frequency was investigated.

Remove the EUT and replace it with substitution antenna. A signal generator was connected to the
substitution antenna by a non-radiating cable. The absolute levels of the spurious emissions were measured
by the substitution.

Spurious emissions in dB =10 1g (TXpwr in Watts/0.001)-the absolute level
Spurious attenuation limit in dB = 43+10 Log10 (power out in Watts)

FCC§2.1055 (d), §95.565- FREQUENCY STABILITY
Applicable Standard
According to FCC §2.1055(a) (1),

The frequency stability shall be measured with variation of ambient temperature from –30 ºC to +50 ºC,
and according to FCC 2.1055(d) (2), the frequency stability shall be measured with reducing primary
supply voltage to the battery operating end point which is specified by the manufacturer.

According to FCC §95.565

 Each FRS transmitter type must be designed such that the carrier frequencies remain within ± 2.5 parts-
per-million of the channel center frequencies specified in § 95.563 during normal operating conditions.


Test Procedure
Frequency Stability vs. Temperature: The equipment under test was connected to an external DC power
supply and the RF output was connected to a Frequency Counter via feed-through attenuators. The EUT
was placed inside the temperature chamber. The DC leads and RF output cable exited the chamber through
an opening made for the purpose.

After the temperature stabilized for approximately 20 minutes, the frequency output was recorded from the
Frequency Counter.

Frequency Stability vs. Voltage:

1)Vary primary supply voltage from 85 to 115 percent of the nominal value for other than hand carried
battery equipment.

(2) For hand carried, battery powered equipment, reduce primary supply voltage to the battery operating
end point which shall be specified by the manufacturer.
 The output frequency was recorded for each voltage.
