The underlying issue is the migration from symbol rate (how much data is moved) to bandwidth (how much frequency space is used). Most of the world has long since moved to frequency management by bandwidth. The United States lags behind in this regard. Both Pactor 3 (P3) and Pactor 4 (P4) take up the same bandwidth as a conventional SSB voice link. P4 uses that space more efficiently, transferring data at over twice the rate of P4.
Sailmail has updated their systems on the marine bands to P4. Many Winlnk stations outside the United States have as well. Only the US continues to limit progress by using the archaic restriction of symbol rate.
Approval of this proposed rulemaking will make Pactor 4 available to cruisers in the US, and encourage continued development of new and faster data protocols and digital voice on the ham bands.
I strongly encourage US citizens to follow the links below to support RM-11708.
A sample statement of support, provided by Phil Sherrod W4PHS, follows the instructions.
