Guest Speaker John VA3KOT – “Narrow Band Emergency Message System”

John talked the need for emergency communications, not for ARES types of disaster events, which occur very infrequently, but for something that is likely to happen more often, like an ice storm or winter snow storm where power and communications are disrupted.

Is voice radio communication the answer? 2M or 70cm repeaters may be down without power, simplex has limited range and it uses bandwidth.
Winlink? It works only with Windows and not open source software, depends on the internet, is email based and needs a 'connection' to function.

CW works and uses less bandwidth than voice, but not everybody knows Morse Code.

There are other digital modes that use less bandwidth than CW and work under the noise floor.

NBEMS is an open source, free, multi platform that can be 'connectionless', ie the signal is broadcast to whoever is receiving, or with a 'connection' to only one receiver for security.
Remember, email does not need to be sent over the internet.

FLDigi (Fast Light Digital) and the suite of products, like FLMsg (Message), FLArq (Automatic Repeat Request), FLWrap (to drag and drop messages), FLAmp (Amateur multicast protocol, for connectionless transfer of files).

FLDigi is open source, run on multiple platforms (Windows, MAC, Linux and more) on powerful processors down to a RaspberryPi, using a soundcard and supports many digital modes.

John demonstrated the use of FLDigi with a RaspberryPi, interfaced to a handheld radio, and received buy cheap off-shore radio, acoustically coupled to an old android smart phone running AndFLMsg. It worked and was done with inexpensive devices.

Upcoming Club Meetings

We begin another meeting season on the first Tuesday of September at the Sharon Temperance Hall at 7:30pm. Our Fall meeting presentations have been set as follows.

  • September 5th: Grant VE3XTV will be bringing along ATV hardware to show what it can do. If you have a receiver bring it with you. The receivers used are standard free to air Satellite receive, for analog FM or digital DVB-S with a Mpeg2 decoder, the IF range is 950 to 2150 MHz; our 23cm band is from 1240 to 1300 MHz. As for the 13cm band (2.3 GHz up to 2.45 GHz) he will bring along a few Satellite down-converters to receive the repeater output at 2370 MHz.

  • October 3rd: Hugh VE3AYR will talk about the VIMY100 special event station.

  • November 7th: John VA3KOT will give a presentation on NBEMS (Narrow Band Emergency Message System).
We are in need of presentations for the club meetings January - May 2018. If you have one that you like to make or know of some one who might do one please let me know.

Thank you Geoff VA3GS for putting this together.

Guest Speaker – John VA3KOT

John spoke on outdoor QRP. His interest in QRP started with scanning and listening to satellites, which lead to his interest in amateur radio, especially QRP. His rules for operating QRP include an efficient antenna, elevation, using CW or digital modes instead of phone, endurance, the use of spotting web sites (to give advance notice to listen), and good propagation conditions.

Since he operates in public spaces, health and safety are important considerations. The passing public needs to be kept safe from RF high voltages etc. and 'no trace' operating means leaving the site tidy when finished.

When hiking, he keeps it simple with a Yaesu FT-817 radio, minimal batteries for lighter weight and a choice of several antennae including vertical, end-fed, loop and NVIS antennae.
