UPGRADE-F to K3BC SSTV



               This is the last revision we expect to make for some time 

          since  we'll  shortly  be leaving on a 6 month cruise  on  our 

          sailboat,  LADY.  As usual the  TVINFO.TXT  location  for more 

          detail on each item is noted in the parenthesis at the end  of 

          each item. Revision F additions are:

               (1)  Added  REAL TIME copy for 256 color  video   boards.   

          [RT.BAS]

               (2) Added a message line to all modes which include a  16 

          line  "shades  of gray" display. The message  appears  in  the 

          "shades" area. You insert a default message (call sign,  name, 

          etc.)  in the SYSTEM CONFIGURATION list in RT, VT, and  ALCHVT 

          and then when you replay a pix or transmit a pix you have  the 

          option to use the default message or to insert a more  contem-

          poraneous comment from the keyboard. [VT.BAS]

               (3)  Added  cursor  selection of files in VT  and  VU  to 

          replace having to type out the file names. This is  switchable 

          in  SYSTEM CONFIGURATION. If you set FI=1 then all file  names 

          in  the designated location are displayed and you  can  select 

          one  by  moving the cursor over it and keying ENTER.  The  a.p 

          default choice is triggered by putting the cursor over a blank 

          area. [VT.BAS]  Also see README2 on this disc.

               (4)  In  the  past  year  the  VESA  standards  for   the 

          640x480x16.7 mil. video mode were changed. Unfortunately, some 

          cards  made  prior to this don't meet the  new  standard.  Our 

          configuration  meets  the new standard  (which  accepts  color 

          bytes in a BGR sequence). If you have an older trucolor  card, 







          it  may have the blue and red colors reversed. While it's  not 

          practical to modify all the programs to accommodate these older 

          cards,  I  did make  a TRUSHO version which has red  and  blue 

          reversed to match the older cards. Named TRUS-REV.BAS, it will 

          give some trucolor viewing with the older cards. This has been 

          tested with the Speedstar 24X. I wouldn't recommend buying one 

          of these older cards, however.

               (5)  Added a section on Batch Files which will  speed  up 

          some  of the repetitive tasks you do  in normal   SSTV  opera-

          tions.  If  you are not yet using these to  directly  transmit 

          GIF, PCX, JPG, and trucolor TGA files from either CD ROM's  or 

          from  memory,  you definitely want to read this  new  section. 

          [BATCH FILES]

               As we write this, we're listening to a station (S.A.)  on 

          14230   with  Rev. E of the system who is giving  a  prolonged 

          monologue  about what the system does or doesn't do---only  he 

          is  completely  wrong ! Obviously he hasn't read  the  UPGRADE 

          text  files.  We suggest you re-read all of the  previous  up-

          grades  to make sure you know what is now included. There  may 

          be goodies you've missed.

               For those of you who are just starting  with the  system, 

          I  apologize  for the disjointed way  TVINFO.TXT,  the  system  

          manual, has developed as we have inserted upgrades info so  it 

          is  readily  identifiable. Some day  we'll try to  give  it  a 

          complete rewrite.



                                                  Have fun,

                                                  Ben Vester, K3BC
