Since the first release of QRS version 1.08 (november 1998) slow-CW on
136kHz has evoluated from a marginal activity to a popular and widely
accepted mode. This created the need to revise QRS, on the one hand to 
add some features requested by users and on the other hand to make slow
CW more efficient and try to reduce the time needed for a QSO.
My thanks go to G3YXM, G0AKN and DK8KW for the suggestions to improve
QRS and/or for testing it.

Changes from QRS version 1.08 to 1.16 :

1. Test mode added (suggestion of G0AKN) :
   Ability to push and release PTT and key for test and tune purposes.

2. QSO mode added :
   Since QRS often is used in combination with the Spectogram software,
   the QSO mode allows optimal use of the screen in combination with 
   Spectogram. It also allows a text of max. 70 characters to be edited 
   and transmitted in a single window.

3. QSK facilities added :
   QSK allows you to listen during your transmission. 
   Following parameters can be set :
   - enable/disbale QSK facility
   - minimum time required to switch to RX (release PTT)
   - time delay between push PTT and start keying
   - time delay between stop keying and release PTT
   The PTT handling is calculated ahead, so QSK will cause no delay to 
   the CW keying. QSK is only available if the speed is given in seconds 
   per dot.

4. Selectable dash to dot ratio :
   If the speed is given in dots per second the dash to dot ratio can be
   set as 3/1 or 2/1. The 2/1 ratio is sufficient to distinguish between 
   dots and dashes using 'videography' and results in an average 20% time 
   saving compared to the 3/1 ratio.

5. Alarm function (suggestion of DK8KW) :
   If the speed is given in seconds per dot an alarm function is available 
   that will alert you a selectable time (up to 999 seconds) before the
   transmission will end. Entering 0 or blank for the alarm time will
   disable this function. To avoid collisions with other software using 
   the soundcard (Spectrogram) the alam signal is given via the PC speaker.

6. If the speed is given in seconds per dot all timing (speed and QSK) is
   truncated to 100ms steps. This was required to avoid glitches between 
   the keying and QSK handling. So if you enter 2789ms dot length this 
   will be truncated to 2700ms (no rounding !).

7. In version 1.08 there was some confusion about when a character was
   transmitted and when it appeared on the screen. Some users preferred
   that the character was transmitted first and then shown on screen
   while others wanted it the other way arround. In the hope to please
   everyone all characters still to be transmitted will appear on screen 
   in gray, while being transmitted the character will be in blue and all
   transmitted characters will appear in black.

8. Some minor 'cosmetics'.
