RFM69HW range test!

[LukaQ]

Right... now you would need to find out receivers Fc and transmitters Fc and align receivers Fc to transmitters.

But doesn't RegAfcFei, bit 2 and 3 do that also? And how big bandwidth do you set, if you don't know yet what is the difference in Fc's? Why would you want to  have narrow bandwidth anyway?

Can I know which antenna can be used for RFM69HCW 915 Mhz , for a range of up to 100-200 feet? Also can I know which antenna was used in your experiment?
