DJs need to arrive 60 minutes before their show for a number of reasons.
Having a DJ in the station while the other is broadcasting helps cut down on suspicious activity and theft, and gives people passing by someone to talk to while the other DJ is occupied with their show. Having only one person at the station at any given time is not only a security risk, but can cause problems when emergencies arise.
DJs are also responsible for keeping the station clean, and tidying up, and this time allows the DJ that luxury.
During that hour, DJs should be preparing for their shows. Your broadcasts will always benefit from this time spent; your playlists will be well thought out, your transitions and talk breaks will be planned, and the over-all sound of your show will improve. Also, this hour will ensure that a DJ may preview unfamiliar music for any swears or inappropriate content.
If you are going to be unavoidably late, call the station on the request line (503-725-5945) at least 60 minutes before your show and inform the DJ preceding you. Being consistently late may result in a strike, and possibly being dismissed from your show.
Missing a shift without arranging for a substitute may result in immediate and permanent dismissal as a DJ on KPSU or at the very least a strike. Tardiness is unacceptable in any form.
