Checking Deviation Check that the deviation in the bandwidth is as the
values below.
± 3.6 ~ Adj. Soft ANT Con
WIDE ± 3.60 ~ 4.50 kHz ±4.5kHz
NARROW ± 1.80 ~ 2.30 kHz ± 1.8 ~
±2.3kHz
Checking Modula- Check that the modulation in the bandwidthtion is as
the value below
WIDE/NARROW 7 ~ 20mV rms 7~20mV ANT Con
rms
Checking CTCSS/ Connect a linear detector via the attenuator
DTCS/5 TONE/ to the antenna terminal, then reset so that
DTMF DEVIATION each signaling type can be output.
DTCS CODE 007
CTCSS 88.5 Hz
5 TONE CCIR 11111
DTMF # (Auto Dial Setting)
Set the linear detector to the following.
HPF OFF
LPF 20 kHz
De-emphasis OFF
Level Meter (P/P)/2
Transmit while making sure no input is
applied to the mic (or mic terminal), and
check that each version in it’s bandwidth
is as the values below, respectively.
Wide CTCSS/DTCS ± 0.50~± 0.90kHz ±0.5-0.9kHz ANT Con
Wide 2/5 TONE/ ± 2.40~± 3.60kHz ±2.4-3.6kHz
