NBEMS/FLDIGI WRAP Checksum Feature

from davekle on 4/25/09

NBEMS/FLDIGI WRAP Checksum feature lets sending stations transmit a plain text message with some very limited embedded coding that includes a checksum calculation. Multiple receiving stations can then verify 100% copy on received text.

FLDIGI 3.11.1 - WRAP/Checksum, on 80m, 100%

from davekle on 4/26/09

NBEMS/FLDIGI 3.11 and higher versions have the ability to confirm 100% copy on received messages in the WRAP/Checksum format. This video is a live demo on 80m. I decided not to do a voice over so viewer could hear the Olivia 8 tone, 500 Hz mode taking hits with my local power line noise while still providing 100% copy!
