Base Radio/Receiver
Description
Transceiver Option Card
An optional board that attaches to the control
board of the transceiver. Provides an internal 10
MHz frequency reference. For conventional base
radio/receiver operation, it also provides the analog
interfaces and WildCard I/Os. The transceiver option
card is available in two categories:
• OCXO (Oven Controlled Crystal Oscillator)
• TCXO (Temperature Compensated Crystal
Oscillator)
The OCXO board when initially powered on
takes a few minutes to reach its operational
temperature. During the warm-up period, if
the base radio or receiver is configured to
use the OCXO frequency reference, the base
radio or receiver may report a frequency
reference failure. This alarm condition
automatically clears once the OCXO board
has warmed up sufficiently to provide a
stable reference.
Fan
Provides intermittent forced air cooling for the power
amplifier and transceiver modules.
