Digital Amateur Radio in Support of Situational Awareness, Common Operating Picture and Community Resilience for 21st Century Emergency Communications

I have watched the presentation by Aleks Rohde W3JAG several times and it seems as if every time I watch it, I learn about a new facet in EmComms.

If the title of this post interests you even in the slightest, then I am sure that you will enjoy the video (Ham Radio Now, Episode 45) http://arvideonews.com/hrn/HRN_Episode_0045.html and will consider it time well spent. Enjoy!

US NATIONAL GRID - A Geo-Spatial Tool for Public Service Communications

See http://www.arrl.org/ares-el?issue=2013-03-20 for details.

To search for iPhone or Android apps, use keyword "MGRS".

I guess that US Amateur Radio operators may be well advised to migrate away from Maidenhead LOC and switch to USNG.

Kudos to Al, KF4KIR for pointing to this information and for immediately getting back to me with additional information!

Due to this new information, RaDAR-America Contest rules will be amended momentarily to the effect that USNG coordinates will be preferred for the logs of US HAMs.

Barrett 2090 CAT PTT control

CAT PTT control has been added to the MARS MIL-STD-188-110A Data Modem Terminal (DMT) software for the Barrett 2000 series (2050, 2090, etc.), thank you to Steve N2CKH for implementing it.

Transmit functions with the following changes to the basic config when running it with the US Navigator:
Data Port 0   9600
CAT COM Port 6  9600

In order to use this software, I am actively seeking fellow HAMs who are interested in digital communications with a Baud rate above 300 (60m Band only).
