I have set up a APRS Igate station on 144.390 using a Alinco DR-135 MkIII with the EJ-41U internal TNC board, I am using my Dell Latitude C640 Laptop with a Mobile Intel Pentium 4 processor, the CPU is 2.00 GHz, there is 1.00 GB of Ram. The operating system is Microsoft Windows XP Professional. This is the same computer I use for Echolink. The software is UI-VIEW32 and Precision Mapping V6 Server. My antenna I'm using is a 4 Element beam. I have it pointed North. I have the radio's power set on 10 watts.
