Pactor-IV (P4) - What is it and what does it do for me? One word--- s  p  e  e  d
SCS tells us that Pactor-4 technology is the absolute fastest a Pactor modem can go on the HF bands and still stay within the internationally mandated bandwidth. With totally new hardware and firmware designs, Pactor-4's  maximum throughput speed of 10,500 bps. is twice (2X) that of  Pactor-III. That means more free time for you to enjoy the sailing life style, and less drain on your ship's batteries.  Here's an actual on-the air throughput speed comparison between Pactor-III and Pactor-4 .

Pactor-III (P-III) 
With nearly a decade of actual real-world operation behind it, Pactor-III is the "Gold Standard" for relatively speedy and reliable digital communications over HF SSB radio. Weather maps and GRIB files take two minutes or less to download with P-III, and depending on message length, e-mail messages can even be faster*.

Actual throughput may fluctuate as a result of propagation and atmospheric noise conditions.

 
Which Radio Modem to Buy - Pactor-4 vs Pactor-3
There are two  modem technologies from which to choose; Pactor III, and Pactor-4. From a Sailmail or Winlink viewpoint, the primary differences between these technologies are:
  1. The newly designed P4dragon DR-7400 & DR-7800 are the fastest modems in the Pactor family, boasting speeds 2x that of Pactor-III modem. The  P4dragon DR-7400 & DR-7800 are plug-compatible with the PTC-IIusb, which means that they use the same interconnecting cables to connect to the ship's SSB radio and computer.
  2. Like its predecessor, the PTC-IIusb, the PTC-IIIusb modem connects directly to a computer's USB port, and gives you computer-controlled frequency selection.
