With Antenna are two options:
A Yagi with 55 elements that provide 20 dB of gain (3 m length), and a yagi with dish like basic element (smaller than 55 element's yagi). Both options are in studying.
I've forgett attach transistors data sheet in last post. They are here:

Ghuettoman,
In this moment, i dont have any web page to show my project. Finally, I will use IAM91563 from HP, like a mixer. I've implemented LNA with two transistors (GaAs FET Siemens CFH120-08) connected in cascade to achieve a 24 dB gain and a 0.2 dB noise figure.

Hi,
Do you want schematic with discrete components or with IC?
If you want with IC, you can use TDA7000, a complete FM radio with minimum external components.

Hi,
Now I work in a development of a Meteosat receiver (1.7 GHz) and a software to decoder HPRT (I will use programs found in internet that use a soundcard to decode image).
This receiver will be added a NOAA station (137 MHz) made 3 years ago (but now need a new decoding...
