| The View Menu allows various filters on what stations will actually be displayed on the map. View settings are not retained across restarts but will revert back to ALL to avoid wondering why you don't see any stations when you return to APRSISCE/32 after having been away for a few days.
ALL
Retains any individually selected options below to allow quick restoration to a filtered view, but displays all stations.
NONE
Unchecks all selections on the view menu. Centered stations and ME will always be displayed.
Ambiguous
Displays all stations that are transmitting beacons including position ambiguity. Non-filled circles are drawn around such stations to indicate that they may more may not be precisely at their displayed position.
Buddies
Displays all stations that APRSISCE/32 considered to be a "Buddy". This includes any station matching any b/xxx or f/xxx filter (including wildcards) and also any station currently centered in any APRSISCE/32 MultiTrack window.
Duplicates
Displays all stations for which suspected duplicate position packets have been received. Duplicates can occur when a portion of the APRS Infrastructure delays packet delivery for more than the default 30 second duplicate detection filter of the APRS-IS transport system. Duplicate packets can make a mobile station appear to ping-pong between new and old positions. APRSISCE/32 highlights such points in purple and does not include them in the track lines.
Invalids
???
Message-able
Displays all stations whose transmissions, either by APRS packet type or application identifier, indicate that they support APRS messaging. If you have ever sent messages to or received messages from a station, it will also be included in the display. These stations will offer "Message" on their popup menu to provide a direct way to open a new chat with that station.
Nicknamed
Displays all stations for which you have defined a Nickname. See also Screen / Labels / Nicknames
NWS Objects
Displays all NWS weather objects. These objects are either directly received via APRS or are internally generated from NWS alerts in conjunction with locally defined shapefiles.
Objects
Displays all objects received from APRS. Objects are typically points of interest like repeaters, hospitals, and other non-APRS stations.
Telemetry
Displays stations for which Telemetry has been received.
Tracks
Displays stations that have moved and therefore have accumulated tracks to display.
EchoLinks
GeoCaches
Platforms
Allows selection of specific APRS platforms to display. Note that counts of stations determined to be of a specific platform are displayed on this menu. Some of the platforms provide additional breakdowns, but selecting any one of the detailed categories sometimes selects the entire category. More work needs to be done here (2011/04/20) to make this behave more consistently.

Shrieks (formerly SkyWarn)
APRSISCE/32 parses any !<nonwhitespace>! from comments and groups (up to 32 of) them into a View / Shrieks submenu. This allows event coordinators to pick a suitable !EVENT! for stations to put in their beacon comment to provide easy on-screen filtering of only the stations participating in the event. The Spotter Network requires their users to put !SN! in their comment, so you can expect to see !SN! in the View / Shrieks menu if any such stations are in your range.
!Shriek!s are also parsed from nickname comments EVEN if the nickname or comment is not enabled! This allows you to nickname your favorite stations with a !WATCHME! comment and then View / Shrieks / !WATCHME! to see ONLY those stations! You could even nickname stations as !VIEW1!, !VIEW2!, !VIEW3!, and so forth to build your own local MultiTrack views of specific stations. A single station can even have multiple !VIEWn! tags in the comment to put them on multiple views.
If nicknames are enabled, and a station has a nickname, and that nickname overrides the comment, then ONLY the comment's Shrieks are used. The comment received from the station will be ignored completely for Shriek purposes. After these conditions are no longer met, a new packet from the station must be received to get a proper !Shriek! for the station.
(So, why "Shriek"? Search for Shriek at Wikipedia)
Symbols
Allows selection of specific symbols to display. The currently centered station's symbol is sorted to the top of the list to allow easy selection of other stations like the centered station. Note that counts of stations using a symbol are displayed on this menu.
Transport
APRSISCE/32 attempts to determine the transports available to a given station based on the contents of received packets. This information is used to optimize some communications with stations on various platforms.
also Digipeater, IGate (these last will display stations that have been observed acting in the specified capacity regardless of what symbol they may be transmitting).
