General; AccessNg An Fm Repeater - Icom ID-1 Instruction Manual

■ General

Repeaters allow you to extend the operatable range, and also
to cover blnd zones. Because a repeater has much hgher
output power than the typcal transcever, and has a wder
coverage area.
Normally, a repeater has ndependent frequency for each re-
ceve and transmt, and a subaudble tone may be requred to
accessng a repeater.
Refer to an amateur rado handbook or a ham magazne for
detals of local FM repeater, such as repeater nput/output
frequences and locaton.
Repeater example;
Receives the 1269.975 MHz signal
and the detected audio signals are
transmitted on 1289.975 MHz simul-
taneously.
Station A:
Tx: 1269.975 MHz
Rx: 1289.975 MHz
Station B:
Tx: 1269.975 MHz
Rx: 1289.975 MHz
REPEATER OPERATION— VOICE
D Repeater operation flow chart
Step 1:
Set the desired operating mode.
Step 2:
Set the desired receive frequency (repeater output frequency).
Step 3:
Set the duplex (shift) direction (–duplex or +duplex).
- Set the offset frequency (shift value), if required.
Step 4 for FM mode:
Set the subaudible tone (repeater tone) encoder
function ON.
- Set the subaudible tone frequency, if required.
Step 4 for Digital voice mode:
Set the desired repeater call sign.
- Set the desired linked repeater call sign, if required.
• The ID-1 USA verson has the auto repeater functon. Thus the step 3
(and 4 n FM mode) may not be necessary, dependng on the settng.
• Repeater settngs can be stored nto a memory channel.
