I noticed the D700A shut itself off yesterday afternoon, and it is on an APC UPS, which did not indicate a 'power out'. I have read about these shutdowns and pressing the power button restored operation (this morning).

I changed the N6ECT-1 beacon to ARPSN-1 Seismic Alert System and will start broadcasting magnitude 3, or above, seismic activity; (imo) a small amount of activity, which is presented in this link **

ARPSN-1 is a "fixed station" running WIDE2-2 - PACKET PATH and my intention is to beacon once per 24 hours; unless there is 3 Magnitude, or greater, seismic activity, based on the following information:

Fix #6, Proportional Pathing for Trackers:

The original APRS design uses a Decaying Algorithm to send new data more frequently than old data, and make each later copy less and less often if the packet is unchanging. Most follow-on APRS clones, and trackers ignored this fundamental principal and transmit far too much duplicate unchanging info. . We need trackers to use direct and local 1 hop paths more often than 2 or 3-hop paths. . I call this Proportional Pathing


Another thing I would like to implement in ARPSN, for reporting purposes, is something mentioned by Bob Bruninga, WB4APR:

APRS Common Bulletin Board for Situational Awareness

I have been reading too much and my right eye is starting to blur again, so I will attempt to divert my attention elsewhere, which brings me to today's project, 'isolating ARPSN-1's main sensor'.

If all goes as expected, I will be able to return the laptop, from the seismic shed to, the house, and have resurrected an old XP PRO tower, that will serve as ARPSN 'back-up', but we will see... and I will report later. (fwiw) This move, if successful, will allow me to begin uploading seismic images and data to the seismic page.

Finally, if one emits APRS traffic in Northern California, (imo) this is a good site to check, frequently:
