Local APRS
This page contains information about the condition of the APRS network in the Western UP. APRS users looking for how to get on APRS or for path information should see the APRS or the APRS local settings page respectively
Michigan UP APRS Network Analysis
We currently have running APRS Network Analysis V1.1.7. This software listens to local traffic heard in Houghton, and checks for consistency with the new WIDEn-n paths. All stations that are green are have paths within specifications, and stations in red or blue have paths that do not conform, and should be changes.

These PHG plots are the new half-size PHG circles that more accurately reflect the range of a mobile unit.
Western UP Packet and APRS Networks
Two main packet networks exist in the UP on 144.390 MHz, and on 145.090 MHz. All packet traffic, including APRS was originally on 145.090 MHZ, presumably because of the low network density the frequency once had, and the interoperability of the two. Existing APRS stations are slowly moving onto 144.390MHz and more stations have been added to the network increasing network reliability in the area. This reliability comes even spacing of digipeaters which can hear more remote areas.
Moving to 4.39
Since most existing digipeaters in the area have either moved onto the shared APRS recently, they have been setup to work with the n-N Paradigm. There are still APRS setups running on 145.090 MHz, that are capable of running the new n-N Paradigm specs and would positively contribute to the network in the UP.
