[Elecraft] PACTOR iii

[Dave Johnson]

Pactor III is 2.4 KHz bandwidth, not 5 KHz.

However, various other modes plague of the amateur bands, it is not
confined to Pactor III. I See ROS stations sending out beacon/CQ calls
endlessly in the hope of someone reporting their signals with a link
back via the internet. Even the lowest symbol rate of ROS spreads 2
KHz on most frequencies, that is 4 characters per second taking up 2
KHz!

Pactor, like Amtor before it, has it's place as a 2 way communications
tool and can take up little bandwidth (P1 or 2, that is), it even
makes for an excellent means of chatting on the keyboard between two
stations. Unfortunately, most of the activity here in Europe seems to
be stations calling into the Winlink network to send pictures (split
into several parts) into the internet and exchange e-mail of a non ham
radio nature. For some bizarre reason officialdom seem to turn a blind
eye to it... Perhaps more so than packet in the past.

On an Elecraft note, my K3 works well on ROS, Amtor and Pactor (I, II
and III). My KPA500 even switches fast enough to use it on Amtor!
