      Hello all,

      I've done extensive testing with the NBEMS/FLDIGI software and it
      just keeps getting better and better. The latest version (3.03) now
      holds the 64 bit interleave (long) setting after program restarts.

      The latest version of the software can be downloaded here:

      Also, I have a yahoo group setup for sharing information on the use
      of NBEMS/FLDIGI/FLARQ and for setting skeds with ops in the Western
      Pennsylvania area, but anyone, anywhere is welcome to join.

      Here's some basic info on the setup and tuning procedures for the use
      of MT63 on NBEMS/FLDIGI:


      NBEMS/FLDIG - MT63 1K/Long Interleave - Instructions for USB ops
      (recommended USB frequencies: 3.590, 7.090, 14.109):

      ### SETUP ###

      1) Go to Configure/Modems and click the MT63 tab.
      2) Click 64 bit interleave long, save configuration, then close (on vs
      3.03 this setting is now saved after restarts of the program).
      3) Go to Op Mode/MT63, arrow over and click on MT63 - 1000.

      ### TUNING ###

      1) Tune transceiver to desired HF frequency (always us USB and make
      sure all DSP, compression and noise blanker settings are disabled).
      2) All stations should always center on 1000 Hz on the waterfall (MT63
      always uses a bottom freq on 500 Hz on transmit. When you initialize
      the MT63 modem, the waterfall tx will be set to this default).
      3) Click tune button in the upper right corner of the program and let
      it transmit for about 10 seconds.
      4) RX stations center on the received 1000 Hz tone by tuning the
      receiver VFO.
      5) Transmit and receive some text to make sure all stations are tuned
      and decoding properly.


      NBEMS/FLDIG - MT63/2K Long Interleave - Instructions for FM
      6m/2m/70cm ops:

      ### SETUP ###

      1) Go to Configure/Modems and click the MT63 tab.
      2) Click 64 bit interleave long, save configuration, then close (on vs
      3.03 this setting is now saved after restarts of the program).
      3) Go to Op Mode/MT63, arrow over and click on MT63 - 2000.

      ### TUNING ###

      1) Tune transceiver to desired FM frequency (make sure all DSP,
      compression and noise blanker settings are disabled and stations
      operating under weak signal conditions should open the squelch on the
      transceiver).
      2) All stations should always center on 1500 Hz on the waterfall (MT63
      always uses a bottom freq on 500 Hz on transmit. When you initialize
      the MT63 modem, the waterfall tx will be set to this default).
      3) Transmit and receive some text to make sure all stations are
      decoding properly. Assuming that all soundcards are properly
      calibrated, no tuning should be necessary.
