I am not sure I quite follow you Rick, I am not sure that the Pactor modes have any higher throughput vs. s/n ratio than the sound card modes. I have not performed the testing myself, but my gut tells me that the PACTOR modes require a fairly high S/N ratio to move data at their highest rates. I think the only limitation in implementing these modes in the Windows environment is timing. The other limiting factor is licensing. 73, Mark N5RFX Need a Digital mode QSO?
