To get a reliable UHF connection, especially at long distances, you need to select a UHF band that is quiet and clean. You don’t want to use a channel that is used by others in your area.
TRIUMPH-LS has UHF spectrum monitoring feature that scans all UHF bands and helpt you to select the cleanest.
Here is the process:
“Scan/Manage Frequency List”: scans frequencies in your list. Color coded information helps you to select the best channel in your list.
The level of interference of band frequencies is shown in scan result. Here 464.550 most probably is used by others.
“Scan UHF Bands”: Scans sub bands in similar way.
