Please try downloading the binary before attempting to compile and link the source code. The binary install is the preferred method. If you have post installation problems the authors and the support team will be able to support your requests much quicker. You will probably find that it runs on your system. It has been tested on several distributions including the latest revisions of Debian, Ubuntu, Kubuntu, Mandriva, Mandrake, SuSE, and Puppy Linux. The Linux binary is a staticly linked executable that only requires hamlib version 1.2.6 on your system. The Windows executable includes hamlib as an integral part of the program.

Before downloading and trying to use this program you should take the time to read the Beginners Guide, the On-Line-Help or download the complete Help file web pages and study them. If you have been running a previous version you will have to configure the new version. You will find many new configurable items. Take time to read about the team and send them a word of thanks at the linuxham yahoo group.

Install from source. If you elect to compile from source you can create an executable that does not require the hamlib library. The instructions on compiling from source should be carefully followed as compiling and linking the program requires several libraries and development headers.
