Hi Rein and Others, I took Rein's presentation and modified it a bit. This upcoming Monday I will give a presentation to our local ARES group. Most of the hams are appliance operators so I took out most of the protocol info. Can any of you please have a look if my presentation makes sense and to see if I have left out any vital information. The presentation can be found here: ODF format 13MB http://k4fau.org/pskmail/PBCARES_PSKmail.odp PDF format 3MB http://k4fau.org/pskmail/PBCARES_PSKmail.pdf Thanks, Sjaak
