I will be traveling to Germany, Austria and Hungary on a river cruise and I would like to take a radio to stay in contact with others on the cruise. I noticed that Europe has a FRS type radio called PMR446. Would there be any issues in taking a Baofeng HT programmed with the PMR frequencies on this trip? I also noticed that there is a new service to supplement the PMR frequencies called LPD433. Any suggestions on which one to use?
