Per my comment about possible new symbols to introduce, I went through the symbol codes defined by OpenTRAC, and found all the symbol meanings that didn't correspond to existing APRS symbol codes. These are what's left of the OpenTRAC codes after eliminating ones that correspond to existing APRS symbols (there were 120 of them). The SAR block seems the highest priority, but there still are lots of other codes that seem like it would be useful to be able to define them, at least as Objects/Items (many of them don't generally correspond to stations).

It was a very subjective process (for example, there are over a dozen airplane codes in OpenTrac which I mapped into either the APRS small airplane icon or the large airplane icon).

So, are any of these worth adding in some of the "holes" in the APRS symbol tables?
