The base station
receiver is not
broadcasting.
Port settings between
reference receiver and radio
are incorrect.
Using the SCS900 software, connect
to the reference radio through the
receiver. If no connection is made,
connect directly to the radio and
change the port settings. Try to
connect through the receiver again
to ensure that they are
communicating.
Corrections are routed to a
port rather than to the
internal radio modem.
Check that corrections are routed
correctly using the receiver keypad
and display.
A rubber duck antenna is
connected directly to the
radio antenna port on the
receiver, or an external
high-gain antenna is
connected via cable to the
radio antenna port on the
receiver.
Check that the connections are made
correctly and to the right connectors.
Ensure that the connectors are
seated tightly, and that there are no
signs of damage to the cable.
