Please have a look at the following Website. As I have been flashing the Retevis RT3 and MD380 for a long time manually now, I still thought this website to be very helpfull.

This is really great stuff. There is a big initiative in Germany to setup a POCSAG based paging network. Please see the following links for more Information:
for those who wondered; yes, on E-Bay you get a 70watt shortwave PA for under 30 Euros from China. It’s a kit, and it does not come with building Information, neither does it come with the schema.
All Information you need though you can find on the Blog from PD7MAA. He was so kind to post the schema and some building information.
