Subject: | [Discuss-gnuradio] problems using USRP as transmitter |
Date: | Wed, 2 Mar 2011 15:42:54 -0000 |
Hello All,
I've got a simple setup in GRC whereby I record a
basic ASK signal directly to a file from a USRP source. After recording the
signal I can sucessfully play it back to a USRP sink. The problem occurs
whenever I attempt to to skip the first step and playback a pre-recorded signal
- theres no transmission from the USRP. Can anybody explain why this is? Is
there some init done by the USRP source instance that isnt performed when the
USRP sink is created in isolation?
Thanks.
Simon Denvir.
