Where can I get an SCS Pactor "TNC" for $300 with the license to run Pactor III? I WILL buy one.

SCAMP, a protocol that employs ARQ to attain reliable delivery, was implemented on a Windows PC with a soundcard rather than an outboard TNC. SCAMP was specifically design to tolerate the long delays caused by the lack of pre-emptive scheduling in Windows. >>>Could Pactor-3 be implemented on a modern PC with a soundcard? Yes, but not with Windows as the operating system. Has anyone done this? No -- it would make no economic sense when you can buy a TNC for $300. >>>Most TNCs are based on microprocessors, some augmented by digital signal processors; both of these devices are controlled by software. While such systems certainly incorporate hardware, they are not hardware-only solutions. 73, Dave, AA6YQ Need a Digital mode QSO?
