RF320-Series Ritron VHF/UHF Radios
connect the input of an RF wattmeter to the radio’s antenna connector. Connect
the output of the RF wattmeter to an RF dummy load with a minimum power
rating of 5 W and an operating frequency range matching that of the radio.
Depress the push-to-talk switch to activate the radio’s transmitter. The RF
output power displayed by the RF wattmeter should be approximately 5 W
with an input voltage of 12.5 Vdc.
8.3.4 Operating Frequency Check (RF Scanner)
Configure a hand-held RF channel-scanner to scan a band of frequencies
covering the radio’s operating frequency. While operating the scanner within
close proximity to the radio and/or its connected antenna, depress the push-to-
talk switch to activate the radio’s transmitter. The scanner should lock onto and
display the radio’s operating frequency. Verify that the displayed frequency is
correct.
8.4 Repair
The RF320-series radios are designed to give years of trouble-free service with
reasonable care. However, if factory repair is needed, first contact a Campbell
Scientific application engineer to obtain an RMA (Return Materials
Authorization) number. An RMA number and product safety documents are
required prior to any repair shipments being accepted at Campbell Scientific.
