4. For LN8 with pins 2–3 and 4–5 linked, adjust the line level control on the front of
the receiver for an audio level of 230mV
rms
.
For LN8 with pins 1–2 linked, adjust RV2 on the backplane for an audio level of
230mV
rms
.
Using transmitter deviation:
This method is not suitable for simplex configured repeaters.
1. Use the RF Test Set to generate an on-channel signal to un-mute the receiver.
2. Modulate the RF carrier with a 1020Hz tone1 at 60% full system deviation, adding
CTCSS tone for a CTCSS system (ensure that CTCSS filtering is applied in the
receiver as required for the actual working system. See Section 3.5 in Part B).
3. Put the T803 unit into Talk Through Mode (also known as Repeater Mode) using
the Mode Toggle button
1
. The Mode LED should be red, constant or flashing, and
the transmitter should be keyed on.
4. For LN8 with pins 2–3 and 4–5 linked, adjust the Line Level control on the front
of the receiver to produce 60% full system deviation at the transmitter RF output
as measured on the test set.
5. For LN8 with pins 1–2 linked, adjust RV2 on the backplane to produce 60% full
system deviation at the transmitter RF output as measured on the test set.
Note: De-Emphasis should be off on the test set receiver.
Using the T803 Line-Out level:
1. Use the RF test set to generate an on-channel signal to un-mute the receiver.
2. Modulate the RF carrier with a 1020Hz tone
2
at 60% full system deviation, adding
CTCSS tone for a CTCSS system (ensure that CTCSS filtering is applied in the
receiver as required for the actual working system. See Section 3.5 in Part B).
3. Put the T803 into Base Station Mode using the Mode Toggle button
1
. The Mode
LED should be green (constant or flashing).
4. For LN8 with pins 2–3 and 4–5 linked, monitor the T803 Line-Out level (600Ω bal-
anced audio) and by adjusting the Line Level control on the front of the receiver,
set this level to equal the programmed ‘Line-Out Level’ as set in PGM800Win.
For LN8 with pins 1–2 linked, monitor the T803 Line-Out level (600Ω balanced
audio) and by adjusting RV2 on the backplane, set this level to equal the pro-
grammed ‘Line-Out Level’ as set in PGM800Win.
1. The Mode Toggle button may be disabled from PGM800Win
2. A 1020Hz tone is used (rather than 1kHz) because some Test Sets can produce unstable
deviation readings
