It would require special software to be able to I don't believe for a second the claims that are made that Pactor III cannot be decoded with software. Software might not be able to be made to work in a full linked mode, but decoding any signal is child's play with the fire power in any modern computer. The DSP algorithms and such that have been developed can decode anything that I know of, if the coding scheme is published. If there is an additional set of codes, which in effect encrypt the link, i.e. IP Sec or others, that would not be legal as all amateur communications are by regulation required to be un-encrypted. If the Pactor III and the WinLink folks have nothing to hide, they should be encouraging someone to develop an open source PT III decoder. As a matter of fact, the ARRL should fund the development of such a beast in my book, if for no other reason to increase the transparency of communications and to allay the rumors and such that Winlink is doing some nefarious. One of the hallmarks of this hobby is the self policing of every communications being able to be monitored by my peer amateurs. This is not possible with PT III and is one of the major issues I have with the whole deal.
