W0KAH

DCS or DTCS on and low power

Hold down Band button and turn radio on
It’s now in CBR
To Exit CBR, turn radio off, hold down Band

Note that the DR-635 will flip-flop frequencies
such that the Transmit frequency will always
show on the Left/Main side of the display
You MUST ID yourself, no automatic ID

Congratulations you are a Repeater Control
Operator!
You must ID for the repeater (the D710 & V71
can do this for you) if your rig doesn’t do it.
You could voice ID; W0KAH via W0KAH
cross-band repeater, but that only handles your
HT and the VHF transmit, you’ll need to switch
freq to 146.67 & transmit low power when the
repeater is not up to ID the UHF transmitter.

USE CTCSS, DCS, DTCS etc. to make UHF
private.
Otherwise other users must ID for the repeater
as well, both directions.
You’re responsible for the repeater and must
shut it down if it causes interference (repeating
intermod for example).
Don’t rebroadcast other services (except WX
service) ever.
Don’t repeat other hams or other repeaters.

When in CBR, the “other” repeater’s carrier
must drop in order to allow your mobile rig to
switch directions, until it drops, you can only
listen because your mobile rig is transmitting to
you.
Use the lowest power on UHF, and as low as
will work on VHF
If you can hear the repeater fine, use Locked
TX A instead of CROSS BAND
Duty cycle is 100% as long as you’re using it!
