Receiver RF and AF Level meters
The UHF-1000 receiver RF icon displays the RF signal strength and AF display
icon displays the audio signal level, from the transmitter.
Receiver Diversity Operation
During operation only one of the A or B Diversity display icons will be lit,
indicating the receiver’s True Diversity circuitry is selecting antenna input A or B
for the best signal. This is normal and ensures that the received audio will not
be interrupted. Sometimes, especially at ranges greater than 75 feet, the
squelch circuit will activate in certain locations of the transmitter with respect to
the receiver. Such areas are called “null spots” and indicate that the transmitter
is out of range for that given location, and the user should move closer to the
receiver or to another area to re-establish the radio link.
