Are you sure you want a throttle block in there. The osmocom source will 
already dictate sampling rate

the docs say:
        N.B. this should only be used in GUI apps where there is no 
other rate limiting block. It is not intended nor effective at precisely 
controlling the rate of samples. That should be controlled by a source 
or sink tied to sample clock. E.g., a USRP or audio card.
