      You might try making the Sound Blaster Card the default and set FLDigi to use the default card instead of picking the soundblaster.  I had to do that for Echolink to work on my Vista Ultimate box.  Just a thought…

      Subject: [linuxham] XP install of FlDigi 3.10

       

      Hello all,

      I've got FLDigi 3.10 working beautifully on my Linux hard drive.
      I have installed it on my XP drive just to test it out.
      I have two sound cards, one on the motherboard which only does OS
      sounds and an Creative SB Live Gamer which is used exclusively for
      sound card modes.

      When I configure the XP install of FlDigi and select the Creative
      card and save the settings it works........once. The fldigi.files
      folder is created in my local user profile like it's supposed to be.

      If I close the program and restart the app I get no audio. The config
      dialog says the program is using the Creative card so the config is
      being saved, but I get NO audio into or out of the program.

      If I delete everything fldigi from the hard drive, unzip the archive,
      start the program, configure it for the correct sound card, save the
      config, it works...........once.

      Open to suggestions.

      TIA

      AC0H

      It would be nice if somewhere are published RTTY weak signal performance comparisons in harsh environment - contest, weak, multipath, echoed, QRM signals etc.

        Can somebody point me to a right direction?

            Hi Martin

            I hope that I am not doing something wrong reposting this, but here Path
            Simulations test comparing RTTY to others modes. This was posted on
            digitalradio@yahoogroups.com a while ago. As you can see , RTTY is not
            doing so well .

            Minimum SNR

            A simulated direct path (no disturbance) was used to establish a
            baseline SNR for each mode. The minimum SNR was determined when all data
            (Pangram text)passed through the simulator without error.

            Ionospheric Simulations

            Propagation simulators are often used to test the performance of HF
            communication systems. Although they cannot duplicate the infinite
            number of complex variations that take place within the ionosphere, they
            can mimic some of the fundamental characteristics of HF path distortion.

            The ionosphere is always in flux so conditions can change from one
            minute to the next. The ionospheric parameters of the simulator remain
            constant which makes for a more level playing field when comparing modes.

            The effects of Doppler and multipath are always present to some degree;
            even on quiet days. Modes that are less robust will start to show a
            decrease in throughput as the magnitude of the distortion increases.

            The simulations should help when choosing an alternative mode that's
            more likely to survive when conditions deteriorate.

            NVIS

            Near Virtical Incidence Skywave

            NVIS waves penetrate deeper into the ionosphere
            than waves that are beamed at low angles. The
            increased interaction with the plasma tends to
            slow the wave down increasing the time-of-flight.
            NVIS sky waves can 'mix' with ground waves due to
            the close proximity of the stations. This causes
            internal timing issues for some digital modes as
            the two signals interact.

            Doppler Tolerance

            JT65 / WSPR

            Both modes seem to have a low tolerance to the increased Doppler spread
            found on high and low latitude paths.In this test, the spread was
            increased until throughput was lost. Spread tolerance was roughly 1.5 Hz
            for WSPR and 3.5 Hz for JT65. A -20db SNR was used for this test since
            both modes are likely to be used for weak-signal work.

            WSJT Mode Description

            FSK441: Intended for VHF/UHF high speed meteor scatter -- not suitable
            for HF.

            JT65: EME and other weak signal work (HF/VHF/UHF)

            JT6M: Specifically developed for 6 meter ion / meteor scatter.

            WSPR: Weak Signal Propagation Reporter (digital beacon).
