I've noticed that there have been several posts inquiring about the Hope RFM12BP module. This module has much improved range, stated as 3000 metres, compared to the Hope RFM12B module with a stated range of 300 metres. As I'm sure many of you would be aware, the Hope RFM12B is the module that is used in the JeeNode series and uses the RF12 library.
Anyway, the bottom-line is that if you would like to read about a recent "successful" build using the Hope RFM12BP, you can find the details at http://littlebirdelectronics.com/blogs/news, under the title "Hope RFM12BP 433Mhz Wireless Arduino Shield". I hope this will help others get this module "up and running" successfully, also.
have a good one!
