Re: MiricsFlexiTV-MSI3101

Hi All, I have a USB dongle with a Mirics tuner which I have tried to get running with libmirisdr. It seems the library is not complete and that it does not configure the chip correctly. I can set a sampling rate and the get sampling rate returns the value that I have set, but the routine to actually set the rate is missing. The sampling rate always becomes 9.142 MHz. As a test I have set the frequency to 500 MHz. The received frequencies are in the range 488.4 to 496.3 MHz. Something is very wrong with the data. If I inject a signal on 490.0 MHz I see four equally strong signals on 496.6, 498.8, 501.2 and 503.4. When the signal is moved towards the center frequency 492.35 MHz, the 498.8 and 501.2 signals move towards the center while the other two signals move towards the passband ends. When looking at the narrowband spectrum of one signal I can see it is actually several equispaced carriers. I have been told that the driver here works: http://blog.palosaari.fi/2013/08/mirics-msi3101-sdr-linux-driver.html Unfortunately I am not much of a programmer, I can not understand how to use the info: http://git.linuxtv.org/anttip/media_tree.git/shortlog/refs/heads/mirics libmirisdr is easy to understand. Very similar to rtlsdr. It would be very interesting to be able to use this dongle and to check what performance one might get from it.
