[aprssig] 9600 APRS net experiment in Central NJ

Regarding NJ APRS, I have this year for the first time in decades actually driven the NJTP about once a month and I am very disappointed that I can drive the entire length of the NJTP (most of NJ) and not see A single Travelers Voice Repeater object.  Hence, I cannot make any voice QSO's because all the repeaters are PL, and without the PL info -or- a QSO in progress AND a PL scanning radio I may as well not even have ham radio.

But if EVERY digi in NJ did as recommended and output once every 10 minutes its locally receommended FREQ object (which includes he tone) then I could at least call CQ on all those unused repeaters or the ones in use but without any PL info.

With 8 APRS model radios that can now display this REAL-TIME info on the front panel, why is it so hard to get the digi owners to implement this.  See www.aprs.org/localinfo.html

Oh, one more beef!  And somewhere along the southern NJTP is someone running Voice Alert all the time and NEVER Monitoring.  DUring this year I hear it on every trip but NOT ONCE has there been an operator present.  ARGH!
