Pardon my ignorance.
I am looking for a list of scanners/recievers that can handle digital.
Also, any good websites for me to read up on the migration from the
traditional analog to digital realm would be great.
Thanks

You will have to sort out what 'digital' means.
300 Baud Kansas City Standard is digital too,
but may be somewhat outdated....

One of the SCCA National Pro Rallies is held nearby (the Rim Of The World Pro
Rally) and there's been a heavy amateur radio involvement, since the local
organizers are both amateurs. It is a great exercise of field operation under
less than ideal conditions; the Rally runs on unpaved mountain roads near
Palmdale, where the terrain is rough and varies between mountain tops,
ridges, valleys and developed areas.
Several years ago, we started using packet radio to relay the entrant scores
(actually, start/finish times for each stage of the race) back to a server at
the event HQ. This way, the scores were captured in real time, allowing very
rapid production of standings. Also, we're likely to spot missing cars much
earlier than in the past.
Historically, we've used ARESDATA as the server running on top of G8BPQ;
it worked, but we kept wanting some minor (and some not so minor) changes.
In particular, we really want to enable 'smart' front-end clients and allow
multiple servers to synchronize with each other. Smart clients *could* be
built on top of the ARESDATA command protocol, I really want something more
sweeping; the first step would be to re-implement the legacy ARESDATA server
functionality so I had a source base to work from.
In the month of February, I worked with another local radio amateur (and
software professional) and we implemented the first iteration of the RimServer
in 100% pure Java.
Database services are provided by a 100% pure Java SQL engine (InstantDB); the
server uses the JDBC API. There's a lot to be said for having an SQL engine
around even for a relatively simple database.
Since there was no ideally portable AX.25 protocol layer to be found, I
implemented AX.25 in Java on top of the JavaComm serial API (strictly
speaking, the AX.25 protocol does not care about the underlaying layer,
which happens to be a KISS driver on top of JavaComm).
User command processing and console functionality is all written in Java, of
course.
I've run the unmodified server on Solaris Intel, Solaris SPARC and Windows 98.
Performance is very good; at 9600 baud, the server is still much faster than
the
radio link. The Win98 system used is an old notebook with a 120MHz Pentium
CPU,
hardly high-powered.
Considering it is a bit of a science fair project, stability is already quite
good, though the acid test will be the actual Rally. There's about 2500 lines
of code, and the compiled JAR file is around 55k in length.
