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. Yahoo Groups DIGSSTV: http://groups.yahoo.com/group/digsstv ===================== 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.

Misc. tab - Click to view Misc. screen and options. RX information line: Green light indicates Soundcard is active. Red/green bars: 1 st bar - Time Sync 2 nd bar - Frame Sync 3 rd bar - FAC (Fast Access Channel) 4 th bar - MSC (Main Service Channel) % - RX signal quality level - equivalent to SNR (Signal to Noise Ratio) RX audio level bar graph. (Higher incoming audio produces more green.) Error offset in Hz - During the DRM transmission, the error in frequency is calculated and the software will adjust for it. Decoded Callsign Mode - DRM submode received. File Name - Note this when selecting the proper file to select for the BSR. Total number of segments in file/Number of segments decoded/Current segment TX information line: TX State - Leadin, DATA, or Leadout. Transmit progress bar indicates the % transmitted. Mode - DRM submode selected for transmit. Total number of seconds to transmit the file. File name to transmit. (This will change when "TRANSMIT" is clicked.) Misc. line: Pic to TX - Transfers image on Misc. screen to TX window. JPEG-2000 compression is applied and filename is changed. Picture in Waiting - Allows access to Misc. image area. Images may be Pasted,loaded, and edited here prior to transmitting. Text for TX - Allows access to text editing area. Text may be typed, pasted, and edited here prior to transmitting. Received TX - Allows access to received text viewing area. All text files received will be displayed in the order they were opened. The text here may be selected and copied, but not edited. ====================== SCREENS ====================== RX/TX IMAGE AREA - Double click for larger view. RX IMAGE AREA - Right click for options: Full Screen (Click to return) Show Thumbnails (or Hide) RX to TX (compressed) Repeat Back RX(as received)NOW Undo Color Adjust Effects Clear - clears RX screen TX IMAGE AREA - Right click for options: Full Screen Show Thumbnails (or Hide) Undo Color Adjust Effects Clear - clears TX screen Misc.IMAGE AREA - Right click for options: Full Screen Show Thumbnails (or Hide) UNDO Color Adjust Effects Clear - clears Misc. screen Show Thumbnails - Select a button to view contents of this folder. 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. ===================================================== The latest version of this file is available here: http://www.tima.com/~djones/easypal.txt Please notify Dave - KB4YZ of updates and corrections: [EMAIL PROTECTED] -- In [email protected], "Andrew O'Brien" <[EMAIL PROTECTED]> wrote: > > I think it is designed to not have help files.
