[Discuss-gnuradio] file transmission with GRC question |

Howdy,
I'm playing around with GRC and trying to transmit a file between two computers (based on Alex Csete's video streaming GRC code).
Transmitter:
USRP1 + LFTX
GRC:
File Source -> Packet Encoder -> GMSK -> Const. Multiply -> USRP sink
Receiver:
USRP1 + LFRX
GRC:
USRP Source -> LPF -> GMSK Demod -> Packet Decoder -> File Sink
I can run the programs (Rx first, then Tx) and I receive the file, but *slightly* smaller than the transmitted file.
The file being transmitted is 2 MB of /dev/urandom and the received file is 8.192e3 bits smaller than the transmitted file.
Any ideas as to where those bits went? Were they lost during synchronization?
Thanks.
-William
