I hear a lot of Pactor on HF, especially 30 meters.  Does anyone know if there is any FREE software out there that supports Pactor, both transmitting and receiving?

Receiving PACTOR 1 with a soundcard interface is doable and, is implemented in MixW.  Transmitting requires some tight timing which does not lend itself to a non real-time OS like Windows (in any flavor).  The one transmit capable program that I know of is HFTerm which, unfortunately, only runs on Linux.

The only Pactor or Amtor mode you can transmit with a sound card and Windows application is FEC (mode B). As stated, the timing consistency of Windows is not accurate enough to support ARQ (mode A) transmit.

WINMOR is becoming very popular in the Winlink2000 circles.

Its an alternative to Pactor, does not require dedicated TNC, it can just use a typical digital soundcard mode setup like your Signalink USB, and it can approach somewhere between(1314 bit/s) which compares very well to the patented and proprietary Pactor II(700 bit/s) and Pactor III(2700 bit/s) in speeds without the need to buy a $1000 TNC that is only available from one company in europe.

I have done it with a MultiPSK and PTT control. Not gonna happen with a vox keyed usb sound link with any OS.

Well maybe Pactor is something I should forget about.  Ive started experimenting with Feld Hell.  This is one nice thing about this hobby...there are many modes to choose from!

Sure thing...do you want to try for this coming Wednesday after 7pm??  I am unable to get on 80m but I can use 40 if that works for you?  Well I should say I can tune the 40m antenna on 80m, but I have to keep it below 10w output and only on the lower end of the band.  If we could swing 40m or higher, that would be better.
