Subject: APRS DECODER version 2.0 now available
==================================
ANNOUNCING <APRSdec>TM Version 2.0
THE FULL APRS DECODER PROGRAM
by Ian Wade, G3NRW
16 June 2000
==================================
<APRSdec> version 2.0 is now available. <APRSdec> parses APRS packets in
TNC/IGate output format or UI-View log format, producing a full decode of
every
data element in each packet.
<APRSdec> is a particularly useful tool for:
o APRS software development and testing.
o PIC development and testing.
o Network fault-finding and diagnostics.
o Learning about the APRS protocol.
o Checking packet formats.
<APRSdec> version 2.0 is a significant enhancement over earlier versions. It
has much improved error checking, and for the first time is provided as a Perl
4
source, allowing it to run on most platforms including DOS, Windows and Linux/
Unix.
<APRSdec> is made available under GNU General Public License.
<APRSdec> is a trademark owned by Ian Wade, G3NRW.
==================
<APRSdec> FEATURES
==================
o Runs under native DOS, Win 95/98 and Linux/Unix. (It will almost
certainly run under Windows NT and Windows 2000 as well, but this
has not been tested).
o Accepts raw input in TNC/IGate output format (TNC_header:data).
o Accepts raw input in UI-View 2-line log format; it is no longer
necessary to edit log files before using <APRSdec>. In addition,
as well as decoding APRS packets, <APRSdec> also decodes the 15-digit
UI-View timestamp.
o Performs rigorous format checking, with detailed error reporting.
o Understands position ambiguity, reporting the bounding box in which
the station is located.
o Compares lat/long position against a prefix/country database -- if
the station's position appears to be outside the country, <APRSdec>
reports a possible anomaly.
o Reports data values in imperial, nautical and metric units.
o Fully decodes Mic-E and compressed position formats.
o Recognizes data from Kenwood TH-D7 and DM-700 radios, and changes
the incorrect DM-700 APRS Data Type Identifier to "Current Mic-E Data".
o Provides detailed weather station reports, including the calculation
of windchill and dew point.
o Decodes storm data.
o Decodes bearing and range data.
o Decodes DX Cluster reports, showing the data as it will appear on TH-D7
and DM-700 screens.

SOME EXAMPLES OF <APRSdec> OUTPUT
=================================
A simple lat/long report:

A raw Mic-E report. <APRSdec> recognizes this comes from a
Kenwood TM-D700 radio and automatically changes the APRS Data
Type to "Current Mic-E data":
