QRS is slow-CW transmitting software running under Windows.
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.
Overview of the changes from QRS version 1.08 to 1.16 :
* Test mode added (suggestion of G0AKN) :
Ability to push and release PTT and key for test and tune purposes.
* 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.
* QSK facilities added :
QSK allows you to listen during the 'key up' periods your transmission.
Several timing parameters can be set to optimize the QSK for your
transmitter. The PTT handling is calculated ahead, so QSK will cause no
delay to the CW keying.
* Selectable dash to dot ratio :
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.
* Alarm function (suggestion of DK8KW) :
An alarm function is available that will alert you a selectable time (up
to 999 seconds) before the transmission will end.
QRS is freeware and can be downloaded from :

- G3YXM's Longwave web-page : http://www.picks.force9.co.uk/136.htm
The 1.08 version at this locations should be replaced by the 1.16 version
the next couple of days.
I can also send it to you via e-mail (180kB zipped), just send a request to
