I recommend the following setup for Skywarn spotters near downtown Minneapolis using a mobile with an output of 25 watts into a 1/4 wave antenna.
Because HTs will have a reduced usable range if no remote receivers are available, I’ll update the list for frequencies to be used when operating with an HT.
162.550 NWS (program this into your WX channel and enable WX alert function)
146.520 Calling frequency (program this into the 'CALL' frequency memory)
146.700 Minneapolis 127.3 CTCSS 127.3
146.700 Plymouth 118.8 CTCSS 127.3
146.760 St. Louis Park backup 114.8
145.170 St. Paul backup 100.0
146.925 Ramsey County backup 107.2 CTCSS 127.3 (Autopatch)
145.430 Hennepin County RACES Edina 127.3 CTCSS 127.3
1. Use your external speaker mic when operating with an HT.
2. Backup repeaters will be announced by Duty NCS based on storm track and availability of repeaters.
UHF frequencies are not considered to be for primary use.
