They’re not really useful except for doing lost squad quests that you can get from other stalkers. Usually they’ll tell you the frequency that they had been using and the location they went missing. It’s not so bad if they go missing in a smaller map but my worst experience was having to search the entirety of the truck graveyard. Reply.RF testing is a way to check the frequency of your radio broadcasts to ensure that they are using their space on the spectrum efficiently. In this sense, efficiency means that the radio waves are not interfering with each other in the air space. Radio frequency tests cover most kinds of broadcasts, including Wi-Fi, GPS, PMR radio, cellular ...

Also, most of the time the RF voltage measurement is made on a "sampled" signal via a coupler. This allows the coax to have a straight-line through to the load (Antenna) with very little loss. Since it is sampled via a coupler, you would need to calibrate the voltage readings which usually requires another quality lab style RF voltmeter. – K7PEH.Test signal power is adjusted for 3 dB increase in level meter reading.
