You are probably not going to get an answer in this forum as quickly as you might in another forum. Right up at the top of the page here it say "ICOM Receivers A forum for the discussion of all ICOM scanning radios and receivers. Please use another appropriate forum for transceivers."
You will probably get a better response in a forum like “GMRS / FRS” or “ICOM Land Mobile Radio”.
