Addgroup: command not found

I also tried to use the command groupadd but nothing changes. What am I doing wrong? Thanks everyone!

Clash Royale CLAN TAG #URR8PPP up vote 1 down vote favorite I sometimes run a VHF radio net for our club, on a 145.170 MHz channel served by a repeater with a -600 KHz offset. People who program their transceiver with the proper repeater offset mode use it with no problem. But some people fail to use repeater offset mode. They transmit simplex on the repeater's output frequency. I hear them, because they happen to be close enough to my station that their signal reaches me simplex. But they aren't using the repeater, and others further away from them don't hear them. Assuming I have spare radios for that band, how can I set them up to detect this situation? I want to find out that it's happening and let them know to fix their transceiver mode. I can imagine setting a spare transceiver to listen, simplex, on the repeater's input frequency. If I see that spare transceiver receive at the same time as I hear the station on the repeater's output frequenc...
