A little known feature in some commercial radios is a very useful RSSI, Received Signal Strength Indicator, meter. The example is my recently acquired Kenwood NX-1300DUK5 radio. The RSSI feature is listed as "maintenance" as one of the selections for the configurable menu items. I added it to one of the user configurable menus. The reading should be in dbm. The current reading shown is -113dbm on the display.
