CONFIGURING THE COMPUTER TO THE PROSKAN SSTV PROGRAM. SETCLOCK.TXT Page 1 19 April 1996 After you install the PROSKAN SSTV program into your computer, you will see that when you run the program for the FIRST time, (by typing in at the prompt, FSCAN.EXE & , you may not be able to get to the Main SSTV Screen untill you complete the 'CONFIGURE' requirements. What will come up on screen is some important information. Read them and hit to continue on. Then the 'PRO_SKAN SSTV SYSTEM' screen will appear on the left side. On the right side is information about Copyrites, your Call being imbedded, etc. Also notice that you can use your Mouse and/or keyboard both here and on the SSTV screen. 1. On the 'Left Screen Box' select "CONFIGURE SYSTEM" A new screen will appear on the right side. Select (0), which is "CALIBRATE CRYSTAL CLOCK" and a Box will come up; follow its instructions. A rough setting has been set in and it must be adjusted by receiving a WFAX signal. The Vertical alignment for receiving pictures as well as transmitting will be incorrect untill you complete the 'CONFIGURE' requirements... 2. First select (F), which is "SET FAX 800X600X16 VMode" . { You can not calibrate the Crystal Clock untill you do this, and also the FAX screen will not appear when selected. } A selection box appears - Highlite the Video card that your computer is using and hit to lock it in. If you don't know what your Video card is, select (?), ENTER UNKNOWN; A box will appear called "CUSTOM VIDEO MODE", with instructions. Hit to return back to the CONFIGURE box. 3. Next Highlite (O), PORT ADDRESS, , Then Highlite the COM PORT number that you are going to use. Hit to lock it in. You can change this anytime if you did it wrong. etc. You can't receive WFAX or any pictures untill this is done. 4. When you have the above completed, tune your radio to a strong WEFAX signal. Here in Ct. we get it strong on 10.864 MHZ USB but on some days we can't even hear it. In that case tune around for another WEFAX station. Some WFAX frequencies are: 3.356, 8.078, 10.978, 10.538, and 14.927. Usually they are on 24 hours but they do take breaks. Tune in on the strongest one. There are many others, so hunt around. By the way, all are Upper Side Band. USB While receiving the WEFAX picture for alignment purposes, try to get the picture as straight as you can through adjusting the Clock Frequency. This means that you have to go back to the Configure screen at (0) to make the correction. You may have to do this a few times, but it is worth it to receive straight pictures. The BACKSPACE Key is used to delete the Frequency numbers one at a time so you can type in the increase or decrease. Try 100 up or down and see if it made the change in the rite direction on the incomming WEFAX signal. Hitting the key will lock it in. P.S. A SSTV station can also be used in scottie one. Page 2 5. Next highlite (B), BASE TIMER 1 or 2. Hitting the Key will toggle it between 1 and 2. Put it at 1 for now if you are not sure if your computer is fast enough. If you are running a 486 DX2 66 MHZ or faster computer, set it to 2. 6. In Base Timer 2 Mode, highlite (Q) "QUICK SET". Hitting the Key once will put in a quick but rough setting to all the SSTV picture modes. In Base Timer Mode 2, you will surely have to make Slant adjustments for each SSTV Mode, but Timer Mode 2 is the best.... There is No "QUICK SET" in Base Timer Mode 1. (Smaller Screen) 7. Next Highlite (C) "CORRECT RX OFFSET". A Box will appear with instructions. Follow the instructions, hit to lock your setting in and Exit. (Option valid only if Memory Manager Act.) 8. Next Highlite (A), "AUDIO TX SOURCE" . A Box will appear for you to enter your AUDIO TONES TRANSMIT SOURCE. (ie. computer Serial Port or Computer speaker). View the file PSCANCBL.PCX for cable making setups. It is strongly advised for you to use the Philbrook Dual Interface for this program if you want outstanding picture quality.
