Cogwheel RX320 Controller for PalmOS

Apr2004 - New version with more features including automatic scan, direct frequency entry, & sleep timer.

Nov2003 - Alpha Release
Here is a very basic but useful controller for the Ten Tec RX-320. This is an alpha release; I don't think you'll find too many bugs, but you will find features missing. Chances are that I've thought of these features and I will add them as time permits.
You can download cogrx320.prc here

What it runs on: PALMOS Version 3.5 or newer, this does NOT include models earlier than the Palm III C. This unfortunately includes the venerable Palm professional and any IBM Workpads, or the earliest models of the handspring visor.

I use it and it runs well on a Palm M100. M100's are under $40 on ebay these days. See for yourself: here.

Tungsten and other PalmOS 5 users will need to download and run loadserlib.prc and run it once
before running cogrx320.prc.

SUPPORT

My ability to support this is very restricted. You might find some conversation about this package on the RX320 YAHOO GROUPS list which I also read.

Having said all that, I hope you find this useful. If you find a real bug or some combination of hardware on which it ought to run and doesn't, you can email me at rx320 (atsign) cogwheel.com
