GnuRadio community, I have been using various hardware interfaces to gnuradio lately.In the simplest example, I noticed an issue with Funcube Pro Plus with broadcast wideband FM (about 4 GRC blocks) whereby it would consistently underflow, even though every rate appeared to be perfect. A crude but effective fix has been to interpolate by 500, decimate by 499. I occasionally notice a similar problem with DVB modules, never with Hermes.
This has caused me to wonder if some subtle error has crept into OSMOCOM or the Funcube module has a timing error (that had been masked previously by OSMOCOM). Am I alone in this (in which case I will look closely at usb/audio/pc hardware)? Thanks in advance, GregNZ8R Gregory W. Ratcliff
