Hi Leon,

Many thanks about this suggestion. But, can you help me with sample calculations about these Rs and Cs, and especialy Ls. (I have read tech docs, but I can hardly remember the theory of filters and things like this - I'm more programmer, than electrical engeneer).

The simplest way to do this is to use the Philips TDA7000 (it just needs
a tuned circuit and a few Rs and Cs). You should be able to find data
and a circuit on the Philips web site. Details are also in the Maplin
catalogue (www.maplin.co.uk). The chip is designed for the VHF/FM
broadcast band (~100 MHz), but I have had one working on the 144 MHz
amateur band, and you should be able to get it working on 150 MHz.
