Spec's Updated March, 2007

COMPUTER

• A dedicated IBM compatible computer, Pentium II class (Intel, AMD etc), running a processor clocked at at least 300 Mhz
  

• At least 128 MB of RAM

• A dedicated hard drive of at least 2 GB

• Basic (legacy) parallel port running LPT1 (or HEX 0x378/9 for the techies)

• Soundcard -  most PCI cards work as do many motherboard based Chipsets. ISA sound cards are no longer supported by the latest versions of the CentOS Linux Operating System.

• Ethernet Adapter (Network Card) connected to the Internet

OPERATING SYSTEM

• IRLP now ships with CentOS, an open source project based on Redhat EL. The custom version we provide is very small, only 150 megabytes on the CD which installs to about 400 megs.
                Help with CD and over-the-net installs can be provided

RF HARDWARE

• Link radio or repeater (the radio must have a COS {carrier operated squelch} signal)

  If the link radio is to be connected directly to the input/output frequencies of a repeater, the repeater MUST not have any hang time or courtesy tone.  This can easily be accomplished using CTCSS on the repeater transmitter that follows the COS of the receiver.

OTHER HARDWARE

• IRLP interface board

• Miscellaneous cables and connectors
