EasyPal Guide - updated 12/22/06

EasyPal is the work of Erik VK4AES.  Do not bother him with emails 
about
the program.  If you need help, someone on the DIGSSTV newsgroup may 
be
able to help you.  Be sure to include the version number in any report
of a problem.  Also keep up to date and use the latest version.

===================== MENU LINE ======================

File:   Twain Select

        Twain Acquire

        Print

        EXIT - Click to close the program.

Setup:  Initial Setup - Enter/change Callsign, CommPort, and 
Soundcard.
                        Click the "OK" button to update/exit.

                        Click the "OK" button to close the window
                        with the message "Some systems may require
                        a program restart".  If you do not exit
                        EasyPal at this time, the transmit frequency
                        of DRM transmissions will be offset by 50 Hz.

        TX Setup - Default DRM Mode should be Mode B, QAM 16,
                   Bandwidth 2.5 khz, Error Protect Normal, and
                   Interleave Short.  On the TX tab, it will appear
                   as "B/2.5/Hi/16/Sht".

                   If EasyPal starts sending in a different mode than
                   selected, change to a different mode and back again
                   before clicking the "OK" button.

                   Start Delay of 12 will reduce transmit time by
                   reducing the number of redundant segments.  For
                   very short transmissions such as Text messages,
                   a Start Delay of 12 may be too short a time for all
                   stations to achieve MSC sync before the 
transmission
                   is finished.  In this case, select a Start Delay 
of 24.
                   The setting of 24 will return when EasyPal is 
restarted.

                   TX DC Freq is best left at the default 350 Hz.

                   RX WFall Offset is best left at the default 0.

                   Form Size - Take care not to size the window too
                               small as you may loose access to the
                               adjustment slider and get the program
                               "stuck" in this size.

        Progressive RX - Check to enable viewing image as it is 
coming in.
                         Using Progressive RX may increase the chance 
of
                         program lock-up or other errors.

        Show RX Full Screen - Image displayed full screen once 
received.
                              Animated GIF files will not be displayed
                              full screen.

        TX WaterFall Monitor - Allows receiving while sending.

                               Turning on the "MONITOR" function on my
                               Icom IC-746 will send my TX audio back 
to
                               the input of my soundcard.  The TX 
signal
                               can be seen in the waterfall.

                               DRM transmissions sent can be copied 
back
                               and decoded.  This includes BSR and 
FIX.

        AutoSave - Check to enable saving of images to "AutoSave" 
folder.

        Show Message Dialogs

        Show Hints - Hints will appear after mouse pointer is placed 
over
                     selected buttons and areas.  "Show Hints" is 
always
                     off when EasyPal is started.

Action:

        Show bsrreq.bin - Allows viewing the contents of the last BSR 
rec.
                          If received from EasyPal, the first number 
is
                          the file ID number.  Next is the last
                          11 characters of the filename.  After that 
is
                          a code for the mode.  All the numbers 
remaining
                          are all the segment numbers required.

        Send BSR request 4 times (bad conds) - Not functional.

        Show TX Volume Control - Allows quick access to Master Volume 
for
                                 soundcard.  All inputs should be 
Muted
                                 except for the Master Volume and 
Wave.
                                 Names for sliders may be different 
for
                                 some soundcards.

        Show RX Volume Control - Allows quick access to Recording 
Control.
                                 Select the input where the received 
audio
                                 comes into the soundcard.

        Show Repeater Commands - Check to enable "Rptr" menu.

        Make W/Fall Picture - Transforms the image on screen into a
                              grey scale image that becomes analog
                              encoded audio to produce a like image
                              in the waterfall.

        Make W/Fall Text - Transforms a user provided text message 
                           with the choice of various sizes and fonts
                           into analog encoded audio to produce the
                           text as an image in the waterfall.

        R/S 60% interleaved redundancy - (Reed-Solomon error 
correction)
                Encodes the transmitted file with redundant data so 
that
                the original file may be created even though not all
                segments were received.  Always on when EasyPal is 
started.
                Uncheck to turn off.  Reload file before transmitting
                when this feature is turned off/on to avoid problems.

                Use of R/S 60% may reduce the need for BSR's and 
FIX'es.
                Transmission time will be increased by 74%.
                File size sent will be 74% more than the original.

                Compatable only with others running EasyPal.
                EasyPal-18-DEC-06 adds a "(E)" prefix to the filename.
                Previous versions used a ".." prefix on the filename.
                The two prefixes are not compatable.

                No progressive receive in this mode.

LoadPIC - Allows for the loading of an image to be transmitted.
          Large images will be resized down to 1280x1024.
          The file will be converted and compressed into a JPEG-2000
          image and the name changed to "Pic-############.JP2".
          The "############" is a 12 digit number representing the
          current year/month/day/hour/minute/seconds.
          Animated GIF's will be renamed but will keep the GIF 
extension.

LoadAny - Allows for the loading of most any file type to be 
transmitted.
          The file will be renamed but will keep the original 
extension.
          This is useful when sending non-animated GIF files where
          conversion to JPEG-2000 is not desired.

Copy    - Standard image copy to clipboard from the RX or TX screen.

Paste   - Standard image paste from clipboard to the RX or TX screen.
          Paste to the TX screen will compress and convert the image
          to JPEG2000 format.

Rptr:   - Clicking any of the repeater access options from the "Rptr"
          menu will immediately start transmitting that command to
          any active HamPAL repeater on frequency:

        a.r     Interrogate External Repeater
        b.r     Request Repeat Back File
        k.r     Send Text to Repeater Waterfall (Includes text 
message)
        c.r     Ask Repeater to Re-send its BSR Request
        f.r     View Repeater Directory
        g.r#    Send Back Specified File (#=number of file)
        i.r     Request Webcam Picture from Any Repeater
(not available) Request Webcam Picture from ??? Repeater
        d.r     Shutdown External Repeater
        e.r     Restart External Repeater

        Hide Repeater Commands - Removes the "Rptr" menu.

Wav  - Brings up the "Select WAV File" list.  Selecting a WAV file
       and clicking "Send" will immediatelly play the audio from this
       WAV file.  Create the wav files using "Make W/Fall Picture",
       "Make W/Fall Text" or another program such as HamPAL or DIGTRX.
       (For versions before 11/DEC/06, abort will drop the PTT but not
       stop the audio.)

Tune - Immediatelly sends the three tone tuning tone for 7 seconds.
       (For versions before 11/DEC/06, abort will drop the PTT but not
       stop the audio.)

TRANSMIT - "<< EASY PAL >>" is sent in the waterfall before the data.
           DRM audio may continue to come out of the soundcard for
           several seconds after the PTT is dropped.

ABORT - Allows for stopping a picture, BSR, or FIX transmission.
        For versions before 11/DEC/06, Tune and Wav audio will 
continue
        even after the PTT is dropped.

BSR - Brings up the "Select File to Repair" window.
      The last image file should have been selected.
      Select the desired file by clicking on the filename.
      "Send BSR Request now" button should be available.
      Sends "**** BSR REQUEST ****" and "<< EASY PAL >>" in the
      waterfall before the data.  An BSR transmission will take at 
least
      20 seconds to send.  During this time as many as 25 instances 
will
      be sent.  When many segments are required, the transmission time
      for the BSR may be as much as a minute.

      In some cases, the "Send BSR Request now" button may not be
      available even when the proper line is selected.  Use the
      "No Filename BSR Request".

FIX - After receiving a BSR, you will have a message on the title bar:

      it may be a message like this:
      "From W8PV You can repair Pic-060927122834.GIF"
       Just click "FIX" to send the FIX.

      or it may be a message like this:
      "This BSR from "KB9RNB" is not from EasyPal. Repair in the 
usual way"
      If you sent this file, just click "FIX" to send the FIX.
      If you did not send the file, the original station may have to 
send
      the fix.
      
      or it may be a message like this:
      "From "W9VMT" You do not have this file. This BSR request is for
       another station"
      In this case, you will have to get the file repaired before you
      will be able to send any fixes.

      If there is no message in the title bar and you got the "File 
OK"
      for the file "bsr.bin", and you think that you should be able to
      send the FIX, go ahead and send the FIX anyway.  It may work!

      The FIX sends "****** BSR FIX ******" and "<< EASY PAL >>" in 
the
      waterfall before the data.  Sometimes sends a "Short FIX", 
a "NUL
      FIX" or no data.

      FIX with no data transmission lasts only 2 seconds.
      "Short FIX" transmission lasts only 8 seconds.
      "NUL FIX" transmission lasts only 22 seconds.
      A valid FIX transmission will be 30 seconds or longer.

      Any station running EasyPal that successfully receives an image,
      can send the fix for any other station that sends an BSR for 
that
      same image from EasyPal.  (The original image may be sent from 
any
      program using a compatable DRM mode.)  If the original image was
      transmitted with a filename that had spaces within the filename,
      it may require the original sender to do the FIX.

      There is no need to reload an image to fix someone.

                  Double click button to view/change folder path.
                  If the AutoSave folder is selected, it will not
                  update until you select another button and then
                  come back to the button for the AutoSave folder.

RX to TX (compressed) - This allows for a replay of the image in the 
RX
                        window.  It will be re-compressed and 
converted
                        to a JPEG-2000 image.  The file will be 
renamed.
                        Quality is reduced each time this type of 
replay
                        is used.

Repeat Back RX (as received) NOW !!! - This will immediately replay 
the
                                       file just received.  It will be
                                       the same file as the original,
                                       the same name and send in the
                                       same mode as the original.

             This will repair any station needing just a few segments.
             When there are many stations that require FIX'es, it may
             be more efficient for one station that received the file
             to do this type of replay.  Multiple stations can relay
             the file to the next.  There will be no loss in quality.

IMAGE AREA - The size of the image area varies with the setting of the
             screen resolution, setting of the "Form Size" under
             "TX Setup", and whether the "Show Thumbs" is selected.

WATERFALL AREA  -  Displays up to 75 seconds of signal reception.

Yellow marker in waterfall = 500 Hz

Green markers in waterfall should match the "Tune" signal or pilot 
carriers.

=====================================================
NOTES:

When EasyPal is started, the contents of the "CompleteFiles" 
and "Corrupt"
folders are deleted.
