Communications networks need participants to work. While FRS was good for two people coordinating a search for a wandering dog, I could call out a request on any channel until I was blue in the face, and the chances (at present) of getting a reply would be minimal at best. A post to the right FB group however, and we had our dog back in an hour, thanks to two people we didn't know, but were community-minded nevertheless. FB is far from perfect, however. While it has extensive community participation, and is easy to join, it runs on privately-owned third-party equipment, and on an infrastructure that is known to suffer localized failures during a disaster. The solution is to generate increased local participation on a resilient peer-to-peer infrastructure. Fortunately, someone has already started such a thing.
AmRRON/TAPRN has established a system for establishing local communications networks called the CH3 Project. It uses five readily-available radio services. Three require no license (MURS, CB, FRS), one requires a license obtainable by only paying a nominal fee (GMRS), and the other rerquires the entry-level Technician class Amateur Radio License (146.420 MHz. in the 2 meter ham band). Certain locations have already established nets, and there is nothing stopping you and your group from establishing on in your area.

Low-Level Voice Intercept (LLVI) is exactly what what the name implies. It's performing point and sector searches for voice communications, and something scanner hobbyists have been doing for decades. Even if all you have is a cheap Chinese HT, you can still run LLVI as it receives the VHF-high and UHF land mobile bands just fine. I've actually had students in previous classes do that, and they managed just fine.
amplified shooting earmuffs that conveniently have a 1/8" audio jack input. It serves both to keep the noise level down at a field LP, and let you hear what's going on around you. A notebook for logging and keeping useful reference material handy. Spare batteries, writing instrument, and something to hold it all that I found at a local army/navy store.
Go visit Radioreference.com to get frequency data for your point and sector searches, use online mapping will show you places that are located above your average terrain for listening. Gear up, take a quick hike, do some listening, and enjoy the view.

Just a reminder that we are one month out from the Basic Grid-Down/Down-Grid Communications, Communications Monitoring, and Signals Intelligence (SIGINT) Class on January 6th. in Watertown, CT.
Signals intelligence (SIGINT) is intelligence-gathering by interception of signals, whether communications between people (communications intelligence—abbreviated to COMINT) or from electronic signals not directly used in communication (electronic intelligence—abbreviated to ELINT). Signals intelligence is a subset of intelligence collection management.
This is a one-day class that covers all the basics you need to set up your monitoring post, collect signals intelligence (SIGINT), get on the air with amateur radio and personal communications services (FRS, GMRS, MURS, CB, Part 15), and establish communications networks and interoperability with other like-minded individuals.

still plenty of time for the rest of you to submit yours. Bonus points to those of you who used the contact form on the right with a Mailinator return address. That shows you've been paying attention.
In the meantime, we have this wonderful article from the Atlantic:
It sure sucks when someone you don't like is in charge, doesn't it?

12V 7.5AH SLABS for $23.83 each in sporting goods next to the trail cams. I still use SLABs when on a budget, weight is not an issue, and charging arrangements are odd. Unlike more modern battery chemistries, SLABs are very tolerant when it comes to charging them in a field expedient manner.
My standard go-to these days for offline writing and diagramming. 97 cents each in the office/school supplies. USA made. Get one for the MONEX this week, and make it your first LP/lab notebook. Bring one to class.
