Winlink bulletins

From Megawiki

Winlink uses an "on-demand" bulletin distribution mechanism. Users must first select requested bulletins from an available "catalog" list managed in Airmail. When bulletin requests are received by a PMBO, a fresh locally cached copy of the requested bulletin is delivered. If no freshly local cached version is available, the PMBO accesses the Internet and finds the bulletin which is then downloaded to the PMBO and then sent to the user. The Global catalog currently includes over 700 available weather, propagation, and information bulletins, including, instructions for using the system, World news, and piracy reports. All Winlink PMBOs support a single Global catalog which insures users can access any bulletin from any PMBO. Bulletins can contain basic text, graphic fax or satellite images, binary or encoded files like GRIB or WMO weather reports. Local processing is used to re-process images to sizes suitable for HF Pactor transmission. The system prevents bulletin duplication and automatically purges obsolete time-sensitive weather bulletins and replaces them with the current version. The system also has the ability to contain bulletins with attachment information which is local to each participating PMBO. This is especially useful for the non-public EMCOMM PMBO which may house valuable procedural information pertinent to complex information or instruction needed by specific agencies in any community emergency.

This is what ARES is utilizing.
