(schwardt, simonr) Fixed long-standing bug in frequency calculation where the RF centre frequency was thought to line up with the start of a channel instead of the middle. As it stands, the channel centre frequencies are already lined up with the middle of each channel. For example, in the 1024-channel case channel 0 straddles 0 Hz in the baseband, the non-existent channel 1024 straddles 400 MHz and therefore the middle channel 512 straddles 200 MHz exactly, which is where the RF centre frequency is mapped.
