      What causes the latency? I just upgraded to a duo-core PC with 8G of RAM and the latency did not get any better from my single core with 2G of RAM. Not as much CPU load, but latency still there.

        The latency is largely caused by the way Micr$oft Windoze handles sound. Suported Cards using ASIO drivers that bypass the Windoze sound routines eg FA-66

          The latency is largely caused by the way Micr$oft Windoze
          handles sound. Suported Cards using ASIO drivers that bypass
          the Windoze sound routines eg FA-66 Delta 44 avoid some
          of these problems. Christos's USB2SDR has negligible latency,
          supports transmit "mike in", CW keying and Hz control of
          an Sis570 VFO as used in the ensemble etc. Also reducing
          the load on the CPU by limiting the display characteristics can
          help.
