Yes Fred, that's normal.
This is one of the main difficulty for a zero IF receiver due to the high level of noise near the carrier.
The SD radio use an IF of several kHz, so this problem is solved.

Subject: [soft_radio] Build a Tayloe detector.

I just finished my first Tayloe mixer and I'm capable of using the Q & I input of the SDRadio.
 
I find a strong (+/- 45db) signal (DC) on the 0 Hz point, I know that there is some more noise at 0Hz but it also give a beat signal.
Is that normal with a Tayloe mixer (direct conversion) or is it something in my build of the mixer?
