Re: [Discuss-gnuradio] First try with RTL2832

Hi Alex,

Thanks for the videos, I had seen some of them before, I am not sure we are using the same modules, the one i am using a much smaller one like the image I have attached.

I am 'playing' with the different parameters today and hopefully I can get some good results from it. My signals are really weak (about -90db with strong FM channel).

BR,

Farhad

Hi Farhad,

As you may have seen in my on air tests I just posted, I have no problem with low signal levels, however, there is an active hardware AGC which may be causing you troubles. If you have a strong signal in the analog passband of the tuner it will drive the gain down and the weaker signal you are trying to receive will become noisy. You can see that in all 3 videos which show an EzCAP666 with E4000 tuner in action.

I don't know if this AGC is in the RTL chip or the E4000 tuner. I suspect it is in the tuner.
