Still working with the polyphase channelizer program. While everything "works", there is something very strange: the output amplitude slowly drops the longer the program runs. As near I can tell, this happens in or following the frequency translating FFT block. To test, I stripped the flowgr

Hi Hoang, the 380MHz is the lower frequency you can get with a RFX400. That's correct. You can chose your daughterboard by using the number of channels argument (if you want both), or the subdev spec [1], like: B:0 to select the WBX in your second slot. Best regards, Marcus [1]http://files.ettu
