IRLP Embedded

January 14, 2003 @ 11:02 pm

This is the second IRLP node I created. The hardware for this node consisted of a Advantech PCM-4823L single board computer (SBC). This board was powered by an AMD 5×86 processor running at a blazing 133MHz. Most common PC interfaces were included, the notable exception was the lack of video support. The SIMM memory slot was filled with 32MB. Network connectivity was provided by an onboard NE2000 compatible 10base-T ethernet interface. A riser card that converted the PC/104 bus to two ISA slots was installed. This riser would hold the sound card and a temporary video card. (more…)

speak_temperature, an IRLP Custom Script

@ 1:14 am

Introduction to speak_temperature
When I first started with IRLP I wrote a few custom scripts for my node. This script announces the temperature. The temperature is obtained via a Dallas DS1820 1-wire sensor attached to the nodes serial port. digitemp is used to read the sensor, a precompiled static digitemp binary has been included for convenience.

cwid, an IRLP Custom Script

@ 12:59 am

Introduction to cwid
When I first started with IRLP I wrote a few custom scripts for my node. This script plays a CW ID on a regular basis. It uses playmidi and a midi file to id the repeater. The scripts default timing adheres to Canadian regulation. It ids at 20 minute intervals, but yields to ongoing conversations for up to an additional 2 minutes. It only ids if there is activity on the repeater. It will not id during extended periods of inactivity. The actual timing is easily configured using variables. (more…)

Trak Pak

October 13, 2002 @ 10:34 pm

The name TrakPak was derived from TinyTrak, a neat little GPS position encoder. This device elimiates the need for a dedicated full blown TNC to report one’s position from a GPS via APRS. The TinyTrak is a product of Byon Garrabrant, N6BG. (more…)

IRLP Then

June 12, 2002 @ 10:53 pm

This is the first IRLP (Internet Radio Linking Project) node I built. The repeater frequency is 147.315 MHz, +600 kHz Offset. A tone of 192.8 Hz was required to access the repeater. The repeater callsign was VA3SLT and the IRLP node ID was 259. (more…)
