I regret that the name FLARQ was not recognized, but Google leads to th right links with its number 1, 2 and 3 hits.
Yes, PSK31 is not the best mode for error free correction, but then again, Amateur Radio is about experimenting and we here in this Forum are especially interested in EmComms. Since the NBEMS suite is for EmComms, why not give it a whirl?!
My testing session did get another Ham in Canada interested in trying out the FLARQ program. What I also noted, was that FLARQ does not allow long individual messages, it's more geared towards sending files.
Will sure try this out more by connecting with: http://www.pa-sitrep.com/NBEMS/
Have now also found the HF Amateur Radio Assistance Network as platform to further the art in communicating with the FLDIGI NBEMS suite http://www.w1hkj.com/
