Step 6. Is base receiver tracking satellites?

The base GPS receiver must be tracking satellites in order to collect the data required
for the radio to transmit. If the base receiver is not tracking at least 4 healthy satel-
lites, no data will be sent to the radio. Use either the front panel of the receiver or the
field application software to determine if the base receiver is tracking satellites.

Step 7 You may have a component that is malfunctioning
.
You may have a malfunctioning radio or radio communication cable.
If using Pacific Crest UHF/VHF radios, it is not possible to further isolate the problem.
Contact your local dealer or Ashtech customer support for assistance.
If using the external Ashtech SSRadio, follow these steps to isolate the problem com-
ponent.
1. Replace the radio cable with the one from the rover system. If the radio
begins to transmit data, there is a problem with the base radio cable. Contact
your local dealer or Ashtech customer support for assistance.
2. If the cable swap fails to identify the problem, replace the radio with the one
found in the rover system. If the radio begins to transmit data, there is a
problem with the base radio. Call your local dealer or Ashtech customer
support for assistance.
