Their sole use appears to be for quasi-commercial operations designed to avoid the tariffs for satellite based data communications options. There is no benefit to Pactor II and III for normal AMATEUR operations and they are major QRM generators often destroying more than 3 KHz at a time. I have often observed Pactor II and Pactor III wipe out the entire 14070-14072 "PSK band" or the entire "digital" area on 17 Meters due transmitting without regard for existing users. Pactor II and III and their operators are a scourge on amateur radio. 73, ...

Re: [Elecraft] OT- HF pactor
Hello Johnny, Pactor is mostly run via SCS modems which are the only modems to cater for the higher speed Pactor II and III modes. There are older modems using Pactor 1, but the main advantage is Pactor only comes from using PII or PIII modes which are highly resistant to QRM, even deliberate attempts at jamming are often unsuccessful against it. I often work a station in Hamburg (around 440 miles away) who runs 5 Watts to a mobile whip antenna on 80m and we are able to communicate fairly easily on any evening. For more information on emergency comms via Pactor see: http://www.winlink.org/ And for details of SCS modems see: http://www.scs-ptc.com/ A K3 works quite well on Pactor, including PIII 73 Dave, G4AON K3/100 #80 === Hello Group, I would like to learn more about HF digital mode communication e.g. pactor. and the application digital mode in emergency communciation. Could any of you direct me to the right website or information source? 73 Johnny VR2XMC __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

Re: [Elecraft] OT- HF pactor
Hi Johnny, Check the Winmor protocol which is being developed and tested just for this purpose. If you google you will for sure find the info.
