Re: [digitalradio] MULTIPSK CW
Hello Dave, If I transmit via the Windows buffering in a tone to the sound card, no problem. If I transmit through the serial port, I need to control the time ellapsed (for a dot or a dash). As under Windows there are no interruptions (sniff), there is no way to know at which moment is the end of the dot (or the dash). So I keep the CPU working in a loop, testing the Windows timer, until the end of the dot. It is not a very elegant method but I don't know an other way to do it. Note: the Delphi system timer is not sufficiently rapid (maximum between 20 to 60 /sec). 73 Patrick - Original Message - From: Dave [EMAIL PROTECTED] To: digitalradio@yahoogroups.com Sent: Thursday, March 09, 2006 3:53 AM Subject: RE: [digitalradio] MULTIPSK CW A 50% cpu load seems really high, Patrick.

However, it is not advised under Windows XP because it takes about 50 % of the computing power (due to the obligation to manage a pseudo timer). The most simple to do CW is to do it as PSK31 (in USB). 73 Patrick - Original Message - From: Box SisteenHundred [EMAIL PROTECTED] To: digitalradio@yahoogroups.com Sent: Wednesday, March 08, 2006 11:36 PM Subject: RE: [digitalradio] MULTIPSK CW That IS cw Paul.
