Another Statewide APRS Net - THIS SATURDAY #ARRL #hamradio

It's that time again,  the Tulsa Digital Radio Club will hold an APRS net at 1300 CDT on Saturday 7/11/2015.


Net controller will be Scott Haley KD5NJR.  




Hams are encouraged to check-in by sending an APRS message to KD5NJR.



As an exercise, try the ANSRVR server.  Subscribe to the OKAPRS group for the duration of the net. Instructions are here : https://www.dropbox.com/s/rgvw6bokclb4ttj/APRS%20Messaging%20TDRC%20Training.pdf?dl=0




The Statewide DMR talkgroup will also be monitored.

APRS messages can be generated from
  • certain HTs and mobile radios (ex: Kenwood TH-D72, TM-D710, etc
  • .smart phones with APRS apps,
  • computers paired with TNCs and radios, and (example : UI-VIEW)
  • computers with soundcard-based modems and radios. (example : UZ7HO Soundmodem and APRSIS32

We continue to operate HF APRS using the instructions located at  http://tulsadigitalradioclub.blogspot.com/2015/03/hf-aprs-fldigi-style-using-pskmfsketc.html .  As an additional incentive for this upcoming net, a certificate of appreciation from the Tulsa Digital Radio Club (TRDC) will be sent to those stations that try this new high-tech wrinkle on the two decades old HF APRS mode.  The HF APRS net will be running on 7036 kHz at a center frequency of 1000 Hz using MFSK-16 for highest robustness during the net.




Popular for about 20 years now, APRS is a format for sending short textual messages over amateur radio.  Short bursts of APRS can conserve your battery power and radio spectrum.  It lends itself to low power applications such as travelers, backpackers and in emergency situations.  APRS radio sets are popular with hikers, experimenters (model airplane and rocket enthusiasts) and there is even an APRS terminal on the International Space Station.   Background information is available at :https://www.dropbox.com/s/rgvw6bokclb4ttj/APRS%20Messaging%20TDRC%20Training.pdf?dl=0
