Hi,
the simple GRC in the attachment creates lots of underflows on our
E100 ("U" on console)
and dropouts when looking at the spectrum.
Is this as expected or how can this overload of the embedded Linux be
avoided?
Thanks,

Well, for one, 60Khz isn't a proper divisor of the 128MHz sample rate of
the DAC, which means it can't be properly interpolated.
The minimum sample rate that you can deliver to the USRP-E100 is
128MHz/512 = 250kHz, so you'll have to interpolate your
data stream up to 250kHz prior to "presentation" to the UHD sink block.
