Miscellaneous Filters

The Miscellaneous filters provide 4 means of restricting displayed messages:

• Filtering by message age, specified in 15 minutes steps for up to 5 hours old.
• Showing only messages from stations that are operator-attended. Operator-attended stations are indicated by an alternate symbol table's symbol code, and an overlay character of capital 'O' (for Operator). Stations that have other or no overlays will not be displayed when this filter is checked.
• Showing only messages with priority or emergency precedence. Emergency precedence is indicated by the text "Emergency" (upper, lower, or mixed-case) or the Emergency A/B/C bits = 000 in the Mic-E destination "callsign". Priority precedence is indicated by specifying the Priority value in the Mic-E A/B/C bits.
• Showing only stations that are directly heard by this station, or local or one-hop from this station.
