Now I am really close, the latest fix for ROM_TABLES did the trick!
I am having an issue with tuning the frequency, following the PLL not
locked messages.

Is this also happening to anyone else? The rtl_test tool also shows
the same messages,
but I also see other people's forum postings who run the rtl-sdr
software successfully, even
with this kind of error message appearing.
