Hi all,I'm observing a DC component inside my spectrum as you can see in the two pictures in attachment (differentfrequency ranges), this DC is only shown when there is no active transmission (only noise). Consider I'm already using the UHD's advanced tuning specifying the LO at 3Mhz. I'm

Hi, Matt in a previous thread you were talking about making d/b that let DC component pass: If there is enough interest, I might make such a set of boards. If someone else is interested in the design, the BasicRX/TX are a great starting point, and I can offer guidance. When i'm inspecting

Hi, thanks for the solution, maybe i'll try with a different transformer to shift the cutoff. When i'm inspecting the my FIR output, it's really difficult to measure a 30ns (one sample) delay if the signal is not clean. This is unrelated to the DC component issue. Blame it on my bad
