APRS Repeater in Davidsonville

John Williams (K8JW) and Gordong Davids (WJ3K) installed and set up the Automated Packet Reporting System (APRS) Digipeater at the AARC clubhouse Friday 26 October, using the high west side antenna.  It operates on the normal APRS network frequency of 144.390 MHz, beaconing every five minutes with a beacon text string of:

!3854.19N/07639.15Wr147.105MHz T107 +060

That includes the geographical coordinates of the site, and the frequency, PL tone, and offset, of the 147.105 wide-area repeater.  The radio is an Alinco DR-135, with an internal Terminal Node Controller (Argent Data Systems OT-135).

Some of its functions can be controlled remotely by designated operators sending APRS messages properly addressed and formatted.  I will monitor it regularly to make sure that it properly fills its purpose.

It can be seen and monitored on the Internet with https://aprs.fi/#!call=a%2FW3VPR-1&timerange=3600&tail=3600.

This digipeater will fill a major gap in the APRS network between Annapolis and Bowie.
