Radio Comms is not my forte, I'm trying to set myself up to use VHF Comms from my private vehicle. I need to be able to listen and talk to the coastguard. Ideally speaking I'm looking for a unit which will not require permanent fixtures in my car (resale issues etc...) is it possible to get a handheld and boost its range with a mag mount antenna? Is it possible to get a set which will plug in to a 3.5mm Jack so I can use it through my current car stereo? Or is it possible to get a set which doubles as a car radio/cd player (doubtful) The technical mumbo on the websites I have found has fried my brain to an extent. Cost is an issue on this set up but I do not want to sacrifice functionality.
