I used to operate Amtor, Pactor I (and Clover II) a decade or two ago, when we had the old Aplink and later Winlink systems. But at the time I did not have a good idea of how deep into the noise these modes could work. Is it possible for some of you folks who have Pactor (II and III as well, if you have that) to determine how deep into the noise they will work until the link slows to unusable levels and compare it with the newer sound card modes that can handle the same conditions?
I do know that when I used to try and connect on Clover II with Ray Petit, W7GHM, we would have what I would call today a moderately weak signal and not have any throughput, yet now it would easily be able to print with Olivia/MFSK16/DominoEX/FEC, etc. Amtor and Pactor would quite working even though you could still hear the tones. One of the numbers I have heard is about -5 S/N where the Pactor modes fail. On the other hand, I recall SCS making the claim that it could operate much lower in the noise than that. Real world testing like some others have been doing with DominoEX et al would be very helpful. 73, Rick, KV9U Andrew O'Brien wrote: > Cheapest foray in to Pactor? > > IF I was to try to become QRV on Pactor (transmit capability), what > is the cheapest way to get going.
