We intend to release the source after an interation or two of review and
clean-up; while the database server might be interesting, the AX.25 protocol
layer is intended to be re-usable and could be the basis of other specialized
packet servers written in Java. I believe the implementation of the AX.25
V2.1
specification is very straightforward and compliant and reasonably complete,
missing only full FRMR support. At some point, I intend to build this using
J2ME + CLDC profile, so that the same AX.25 layer would be used in the smart
clients.
As for Java being the way to go, here's a case of where I wanted to build a
highly portable server; Java was a key advantage here. Further, JDBC exposes
full capabilities of an SQL engine (in my case I'm using a Java SQL engine
(InstantDB) which has worked well, but you can select many other 'larger'
SQL engines under JDBC). If you're building an application and/or server
where run-time portability is key, Java is a compelling alternative to
Perl and shell scripts.
Stay tuned, there will be more to come later, probably in May or June,
with the eventual posting of the sources to a web page.

HI Charles,
How about a client server logging program on the AS/400 You could use a VB
front end ( or Java ) or even a rig control program ? My programmer is just
back from a Java course and I need to get him to prove to me that Java is
the way to go with the AS/400. I'd love it if he did some radio stuff but
since I'm the manager I'll have to suggest some mundane work stuff :(

That's still a bit above what I know. I've mostly been doing local apps
and transfer files in RPG IV (ILE). There is a book I saw once but have
been unable to find since, a book on Java for RPG programmers.

Sounds like you're successfully reading the input, which is in the time
domain. If you want frequency and amplitude, try running the data through
an fft. You can probably find lots of references and sample code by
searching for 'fft' in infoseek or some other search engine. Good luck!
