Ah, but you are mixing apples and oranges. Even in PC RTTY, bit timing has always been done in hardware. It is handled in the UART (typically an 8250 compatible UART) and not done using a software timing loop that can be effected by operating system loading. Before you point to EXTFSK ... EXTFSK uses a hardware timer in the motherboard chipset - it does not rely on a software timing loop like all of the CW software. > -----Original Message----- > From: elecraft-boun...@mailman.qth.net > [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Brian Alsop > Sent: Thursday, February 26, 2009 10:02 AM > To: elecraft@mailman.qth.net > Subject: Re: [Elecraft] K3 choppy CW > > > Agree with Ed.
