DB0FHN is a central server for the AX.25 packet radio network in europe. You can access DB0FHN by packet radio or the internet.

__**Rules**__\\ 
You have to be a licensed hamradio operator to use __radio__ services of DB0FHN. Maybe DB0FHN will grant access to more services than allowed. It is **your** job to care about the rules for hamradio depending on your current location (country).

__**Passwords**__\\ 
DB0FHN needs to authenticate amateur radio operators to avoid abuse of the radio services DB0FHN offers. To reduce administration work you have to set your passwords yourself by packet radio.
