Hi Jeroen, OK I applied and tested the patch, works great with the codectx/codecrx options:
$ ./freedv_tx 700D ../../raw/ve9qrp_10s.raw - --codectx | ./freedv_rx 700D - - --codecrx | aplay -f S16 I just edited out a couple of fprintfs that were dumping info to stderr. All checked in to SVN 3757. -/- Alan - apologies of this overlaps any of your work, I should have been faster in applying Jeroen's patch. Pls review the changes with Jeroen's patch and send me a new patch with your work and I'll take a look at it. It's OK to email me directly if you like.
