I run the Hengoed PMR 446Mhz gateway, to connect to this gateway you first need to be in radio range of the gateway access point, call on 446.08125 and use CTCSS of 131.8. due to the low power output of PMR transmitting range is limited, but if you are in the range of the access point then you will be connected to the rest of the world via the Internet.
Calling is very informal, use a call sign or your name and say you are calling through the gateway.

If you wish to join a conservation then wait for a gap and call QSK and wait to be called into the conversion.
