Disabling RTL2832 AGC

A couple of days ago I posted on Reddit a small modification to librtlsdr.c to disable the RTL2832 AGC and internal amplifiers (link to post: http://www.reddit.com/r/RTLSDR/comments/vunuy/experiments_with_agc/c57sbpx the correct part is after the EDIT). Add the following lines of code: /* disable RF and IF AGC */ uint16_t tmp; tmp = rtlsdr_demod_read_reg(dev, 1, 0x04, 1); tmp &= ~0xc0; rtlsdr_demod_write_reg(dev, 1, 0x04, tmp, 1); /* disable AGC PGA */ rtlsdr_demod_write_reg(dev, 1, 0xd7, 0x00, 1); /* disable GI PGA */ rtlsdr_demod_write_reg(dev, 1, 0xe5, 0x00, 1); just after: /* disable AGC (en_dagc, bit 0) */ rtlsdr_demod_write_reg(dev, 1, 0x11, 0x00, 1); Since I don't have adequate tools to test the results, could you please test it, and if it does work, add the patch to your repository?
