SNCU hosts a ‘net check-in’ for Family Radio Service (FRS) and General Mobile Radio Service (GMRS) radio operators monthly on the first Monday of each month at 7:00pm on channel 17. Previously attending GMRS operators are called upon using their ‘call sign’ first. Other GMRS operators are asked to check-in next. And FRS operators are asked to check-in last. Additional time for messages and inquiry is opened after the full check-in.
