Hi David!
I'd be very lazy: just pad your pre-recorded signal with zeros, and play it on loop with
the file source.
Padding of files is easy, and essentially free in terms of storage space if your file
system supports sparse files (and if you're on linux, yes, it almost certainly does).

The lowest RTL supported sampling rate is 250K, and then there's a jump
with no supported
rates until something like 900K.
For a single WBFM channel, you need the 250K sampling
Is 32k a supported sampling rate? Sounds two orders of magnitude too low.

The error about PLL should be just "cosmetic" and not have any impact.
Anyway, I think I setup correctly both the correct frequency (I would
like to test the broadband FM, so 100e6) both the sampling frequency
(32k).
The real issue is the "Return code -11" error, I cannot find anything
about that.
Hi,
did you set the correct frequency? If it is outside the allowed range,
it is expected that the PLL cannot lock.
Best,
Fabian
