I read the below statement on Polling in BoatUS FAQ for MMSI; OOPS, title's wrong MMSI!!
"The polling function on your radio allows you to obtain the position of a specific vessel using their MMSI number. If their radio is operating within transmission range and is hooked up to their GPS, their position will be transmitted back to you. That can be automatic if the radio has been set up for automatic response (the default setting on many radios), or it can require you to manually authorize the response. Conversely, anyone polling your radio can get your position without your sending it manually if you have set up automatic response and your radio is connected to a GPS. The display will show that someone has polled your position, and an alarm will sound; however, the alarm can be turned off or be too quiet to hear. If you do not want your position sent automatically to a polling request, see your owner's manual to determine how to set up your radio so that you have to authorize it manually."
Can one of you techno wizards expound on this, please.
Are RT's VHF hooked up to the GPS?
Thank you!
