211121, the "EMCOMM Hub" on Keller at 2000 hours, Sunday, Continued "Information on MESH Network" with Jim, AG6IF and "LiFePO4 RV Conversion from Lead Acid" with Tony, AJ6GN


  Mission Statement for the "EMCOMM Hub" on Keller:  

"Provide a networking environment that fosters sound Keller Peak Repeater practices with respect to emergency communications and preparedness."

  • All amateur radio operators are invited to participate.
  • To follow along you can find tonight's outline at hub.rivecg.net along with many past topics/information for reference.
  • Held every Sunday night at 2000 hours (8 p.m.) California local time.
    • KPRA 146.385 (+) PL 146.2
    • or, KE6TZG-R on Echolink
I.    Administrative:

For operational guidance; always refer to the KPRA guidelines found here:  http://kpra.net/guidelines.html

NOTE:  If you would like to be a featured guest who has an organization that meets the net criteria and you would like to highlight it in a subsequent net, please open a dialog with Rick, KK6CTT at rngr86@...  Please put "EMCOMM Hub" in the subject line for easy identification.


  • Facilitate education and training that draws willing amateur radio operators to serve as stewards of the Keller Peak emergency communications community.  Become "The Hub" of information that prepares us to efficiently recognize and adjust to situations where proper handling of priority and emergency traffic is necessary.
  • Allow groups and individuals who participate in emergency communications and preparedness to share their experiences while providing opportunities for operators to volunteer with the organizations that provide the best fit.
  • Establish sound practices within the Keller Peak Repeater Association that recognizes and addresses the "greater good" principle in the eventuality the repeater becomes "The Hub" of emergency communication operations.
  • Flow of the net will include the following but will remain flexible:
    • Any updates from KE6RYZ, Dennis concerning the repeater.
    • Guest speaker(s) sharing personal, agency or organization information (see "scope of this net"):
      • Personal experience due to an event or personal knowledge based on work/volunteer experience.
      • Governmental or Nongovernmental organization (NGO) viewpoint.
      • Or, the club frame of reference.
    • Public Service Announcement:
      • Wrap up with something relative to the group that ends the net on a positive note.
Frequently heard courtesy tones on the repeater:
  • Dah Dit Dit Dit (- . . .):  "B" signifies the repeater is running on back-up power:
    • "Routine" QSOs should be avoided.
    • Brief "Priority" and "Emergency" traffic may be passed which may include directing operators to another repeater or simplex net.
    • Net controllers please refrain from conducting roll calls and use the net to share or exchange only important information.
  • Dah Dah Dit (- - .):  The "G" tone identifies power is derived through onsite generator backup power:
    • "Routine" QSOs should be avoided.
    • Brief "Priority" and "Emergency" traffic may be passed which may include directing operators to another repeater or simplex net.
    • Net controllers please refrain from conducting roll calls and use the net to share or exchange only important information.
  • Dah Dit Dah (- . -):  The "K" tone signifies the repeater has dropped and is awaiting the next station.
  • Dah Dit (- .):  The "N" signifies the repeater is in "net" mode.  This may include automatically or manually linked reflectors/nodes.
II.   Check-ins
  • IRLP and EchoLink Check-ins:  Call, Name & Location
  • RF Check-ins:  Blocks of 5 calls:  Call, Name & Location
    • We will:
      • Check-in participants as we get comments, questions and suggestions.
      • Ask for check-ins at the end of the net (time permitting).
III.   Announcements:
  • Amateur License Testing, every 2nd Tuesdays of the month 0800, $15 Exam fee
    • American Legion Post 426, Yucaipa, 12167 California St. TO REGISTER send Email to wd6h@...
  • Local Tech Net on the W6JBT Repeater:  https://w6jbt.org/
    • Each weekday morning the “Tech Net” is held from 0700-0800 on the W6JBT repeater or Echolink at W6JBT-R.  This net is designed to bring local hams together to talk about radio issues, new products; questions and answers about everything “ham."
  • Looking for more net time?  We've had some good reports of a welcoming repeater further west that holds two weekday nets at 0900 and 2100 hours on the Catalina Repeater:  http://www.cara.radio/
  • Of course, there are the several Keller Peak nets featured here:  https://kpra.net/nets.html
  • Any other announcements?  Please send them to Rick, rngr86@... if you would like to make an announcement during the net.

IV.  Jim, AG6IF will help provide information on MESH networks, more specifically the AREDN network tonight based on interest in this topic from past week's topics.
  • This is a huge topic and we will try to focus on what AREDN is and how to get started.
  • AREDN website:  https://www.arednmesh.org/
    • This is one of those topics we will probably not be able to answer all questions in one net and it will require the operator to do individual research to get better acquainted with this resource available to amateur operators.
    • AREDN Mission:  "The primary goal of the AREDN® project is to empower licensed amateur radio operators to quickly and easily deploy high-speed data networks when and where they are needed."
    • AREDN Overview
    • Selecting Hardware
    • Before you get started and think it is time to purchase equipment and "flash" your equipment to the amateur radio frequencies...Proceed with caution.  Doing this incorrectly can result in "bricking" your device rendering your newly purchased equipment useless.
  • Below, I have hand picked several slides for a point of reference out of an 83 slide presentation that has been used for this purpose in the past.
o  1-2:  Credit for parts of this presentation attributed to below slide, Orv Beach, W6BI & warning of "radiation exposure"
o  3-4:  Software support & Band information
o  5-6:  How they work (like radios) & Examples of what it can support
o  7-8:  It truly can be the future of how information is sent & Winlink as an example
o  9-10:  Pier to pier or keyboard to keyboard & Hubs of communication platforms that provide real time examples
o  11-12:  VOIP phones & VOIP PBX systems can be used just like those supported by the internet and commercial lines (limitations and through-put capacity dependent
o  13-14:  Webinar style discussions & servers that can be used to distribute or provide a "one source" atmosphere
o  15-16:  The MESH network is self-healing as long as there are other nodes supporting "a better path" & an example of using cameras to provide situational awareness "real time" (resource throughput dependent)
o  17-18:  Document sharing simulations of what is available on the internet & Mapping and useful data is available to help determine "best connection" probability
o  19-20: Getting into hardware and what to be aware of & where it started and where to look now for supporting hardware (suggested hardware)
o  21-22: Both showing a few generations back.  They work but there is better equipment out there
o  23-24:  The newer generation of equipment with more focused directional qualities; Mikrotik and TP Link starting to edge out Ubiquiti hardware due to cost and availability
o  25-26:  Mikrotik LDF 5
o  27-28:  Wait for it...  Wait for it...  TP-Link is coming out with the CPE-710 and falls in the recommended list.
o  29-30:  
o  31-32:  
o  33-34:  
o  35-36: 
o  37-38: Learning the MESH frequency band plan
o  39-40: What you will see when you visit the AREDN interface to include the status of registered nodes
o  41-42:  Additional information
o  43-44:  AREDN has your answer although there is a lot of information to look through & coverage tools to help with LOS modeling
o  45-46:  Suggested ways to get started and a revisit to exposure hazards

  • A lot of content and without getting to far into the weeds, are there any questions or comments?
  • Any interest in GMRS and the other frequency bands after last week's discussion?
  • Next week?
