During weather events NWS Slidell operates FM on the 147.270 (-) pl 114.8 repeater. This repeater has wide coverage but not sure if you can make it from
NWS also uses the old standard ax25 packet system on 145.010. The antenna for this system is at 500ft and also has wide coverage. THIS IS NOT APRS. This is a
standard packet system. W5SLA, operates in the following manner:
The main digi is not a node but standard tnc. You can digipete through the system using th via command and call sign w5sla-4 or sil. You cannot connect to and
then connect to another station.
W5SLA-3 is the mail box where we will post wx bulletins during activation. It can also be used to leave messages for other hams.
W5SLA-5 is the mail box at the NWS office in Slidell where you can inform us of wx events in the field. This is monitored 24/7 whether emergency or not.
You will probably need to digi thru another station to get to the NWS station.
This is used mainly during hurricanes but can be used during other events.
