I successfully loaded FDV and tried it with another ham with Flex and FDV. The transmission looks normal but the receive audio is somewhat garbled and unnatural, is difficult if not impossible to understand, and comes out only the left earphone. I have RIT off and have carefully tuned in the other station. In listening to other DV transmissions, some are better but all sound about the same. Is this all normal or perhaps I have something set up wrong.
