APRS Activities:

    N3XKU: Home APRS station. Runs 24/7 with the equipment listed above, attached to a home computer running WinAPRS.  All received data is echoed onto the internet through one of many APRS TCP/IP Servers.  This station covers portions of Bucks, Philadelphia, Mercer and Burlington counties.  This station is also equipped with battery backup and can continue APRS duties on emergency power.  This station no longer serves as a RELAY digipeater now that the much more capable N3XKU-15 digipeater has come on air in Bensalem. 

    N3XKU-9: Mobile APRS Station running the above listed equipment.  TinyTrak3 is equipped with a switch to change path on the fly between "WIDE1-1,WIDE2-1" and "WIDE1-1,WIDE2-2" depending on how far I'm going. I've also attached a pushbutton for forcing a position transmit at the end of my trip. Unlike standard time-based trackers, the TinyTrak3 will beacon more often the faster you go, and will greatly reduce the beacon rate when you stop moving.  It will also transmit every time you turn a corner for nicer looking track maps.

    N3XKU-8: Mobile APRS station running the above equipment.  TH-D7a receives GPS data from a Motorola i730 phone. It's mounted up front to take advantage of its ability to send and receive messages, and view live APRS data (only when parked of course)

    N3XKU-15: NEW! Wide area digipeater in Bensalem, PA replacing the old K3ATI-11.  This digipeater is using the new APRS paradigm parameters to help control traffic in the area.

   W3SK: Penn Wireless Association Fill-In digipeater in Southampton PA.  On the air thanks to Jason, Cully, and I, this station fills one of many gaps in the area. I am one of the remote operators of this station and tweak the settings as necessary. This digipeater uses the new paradigm Fill-In alias of WIDE1-1, as RELAY is now obsolete.

***** APRS Paths containing "RELAY", "WIDE", or "TRACE" are now obsolete and should not be used in any packets!

***** Contact your local Digi owner and remind them why they need to change their parameters for a better APRS Network, and remind your nearby users to stop using paths containing the obsolete aliases.

Other Activities:

    ARES/RACES member and advanced SKYWARN storm spotter.  I am an APRS net control on the weekly Skywarn net.
