AmRRON will be holding a 4th quarter 2019 Simulated Emergency Test on November 9th.

Quarterly Communications SETs (Simulated Emergency Tests) help AmRRON radio operators practice with skills, software programs, and procedures, preparing them for more complex training and real-world radio operations.

Get the website URL contained in the November 5th AIB, and on Saturday, get the ‘secret exercise code’ from the Situation Report. Then, fill out a super short survey online!

Who: AmRRON and all other orgs and radio operators wishing to participate

What: Quarterly Training Exercise (4 hours): Delivery of a single message, network wide

When: November 9th, 1800 – 2200 Zulu Time

Scope: Nationwide, beginning on HF using digital modes, and then filtering down to local VHF/CH3.

Objective: This is a one way traffic test. In this quarterly exercise, a single SITREP (Situation Report) will be generated at ‘AmRRON National’, and sent across the network to Net Control Stations (NCSs), nationwide. The NCSs will then disseminate the report across their regional network in each region on 40m and 80m using digital modes.

Local VHF/CH3 nets will then disseminate the report to the local radio operators. Then, all participants fill out a short online survey to verify receipt of the SITREP…

AmPart: An SHTF Perspective on Commo

NC Scout at American Partisan sends some communication insights from someone on the ground in the Ecuador civil unrest – A SHTF Perspective on Commo.

In a real deal SHTF situation, such as a nation in turmoil and civil chaos, how would you fare? When the infrastructure goes down and there’s dead in the streets, what will you do?

That’s a reality for one of AP’s readers living in Ecuador, who’s been giving me steady updates on the deteriorating situation there. He first contacted me over a year ago trying to get their communications up to speed at the local Red Cross chapter. Years of neglect and a focus on more convenient systems caused their antennas to deteriorate and a lack of any knowledgeable operators. If that was bad enough, Simply getting equipment into the country is a challenge…

Off Grid Ham: Grounding Your Off Grid System

Chris Warren over at Off Grid Ham has a nice article about the often confusing concept and execution of system grounding in Grounding Your Off Grid System. He’s not just talking about grounding your communications gear, but also your solar panels, and generators. Don’t get burned; learn to ground.

It’s hard to follow.

One issue that seems to come up a lot in the off grid radio realm is proper system grounding. The rules and expectations are hard to follow. There are a lot of opinions out there. Many of them are accurate, others are not. Today we’ll go over some basic grounding principles for off grid ham radio. This is by no means a comprehensive guide.

All the same basic grounding concerns with commercial power also apply to off grid energy. Electricity does not behave differently just because it comes from a renewable source. Finally, lightning does not discriminate!

What exactly is “ground”?

In the most simple terms, “ground” is a reference point. If you remember your basic electricity training for your amateur radio license, voltage is an expression of potential energy. However, potential doesn’t mean anything unless it is compared to something. For example, if you are standing on the roof of your house you have potential energy (via gravity) when compared to your yard. If you are laying flat on your back in your yard you have no potential energy compared to the yard because, after all, you’re already in the yard. You can’t fall if you’re already down, right?

Electrical grounding works the same way. Electricity needs a place to go, and it will not go anywhere without potential. Ground provides an electrical reference point. This has many implications for the operational effectiveness and safety of your off grid system.

Grounding outdoor equipment.

If electricity needs a place to go, it’s best for it to have a defined safe path instead of letting it find its own way. Off grid hams should place a high priority on grounding antennas and solar panels.

Connect (bond) solar panel frames together with 6 gauge copper wire attached to a conductive metal pipe or rod pounded into the ground. Be sure also to connect any metal support structures. Grounding lugs made specifically for solar panels are available from many sources including (of course) Amazon. Ground rods should be at least six and preferably eight feet deep. Getting a ground rod down that far will be a problem for many hams. You can substitute two or more shorter rods in place of one long one (be sure to bond the rods to each other).

AmPart: Signals Intelligence – Electronic Isolation Of A Target

NC Scout at American Partisan has written an article on signals intelligence and how to exploit it to disrupt an enemy’s communications. Please note that disrupting someone’s radio communications during peacetime is usually illegal. The FCC can fine you thousands of dollars, revoke any radio licenses you have, and confiscate your radio equipment.

Signals Intelligence: Electronic Isolation Of A Target

Not too long ago I ran a short post over at Brushbeater noting a story from the Marine Corps, pairing signals collection guys with Scout Snipers in a somewhat new small unit strategy. Building on the successes SOF units have had for a long time now in recognizing the rapid value of SIGINT in the field, pairing the two elements only makes sense. The idea is to isolate a target where they’re most vulnerable- electronic communications- in order to end the fight quickly with as few casualties on our side as possible. And working from a prepared citizen’s point of view, those same capabilities can and should be reflected in your own training.

It’s not enough to simply have a scanner, however nice it might be, and call yourself good on signals intelligence. Situational awareness, maybe, maybe, but none of it will do you much good without a means to exploit what ever it is you’ve collected.

The purpose of intelligence is exploitation. 

Recording voice traffic with common items makes exploitation easy

What that means in practical terms is that unless I can do anything with what I’m hearing, its completely useless to me. So what if I hear some traffic on a random frequency. Did I take the time to record it? What did they actually say? What is their level of training or discipline? Who’s the person in charge on the mic?

We can listen to all the traffic we want, but if we have no way of exploiting that, then we’re wasting our time.

Some of the equipment you’ll need for a signals collection package at the small unit level includes a decent scanner capable of decoding P25, a communications receiver, an inexpensive analog radio,  a recording device, a Yagi, and a frequency counter. Most of the higher end scanners on the market have up-gradable firmware that is enabling the decoding of P25 modes in use with public service as well as DMR which is very common today in the US as well as being used in Ukraine and Syria among guerrillas. A communications receiver, while similar to a scanner, will tell us the exact frequency the traffic is on, unlike most digital scanners today. We need to know this in order to have the operating frequency- its not enough to know what they’re saying, but we need to know what frequency they’re on so that if we decide to shut down their communications, we can effectively attack.

Our inexpensive analog radio enables us to not just have additional redundancy in our kit, but it’s also a useful exploitation tool. Depending on what type of gear your opponent has, something like a UV-5R can become our weapon in shutting their communications down. Using a Yagi to first get a bearing on their direction and then focus our signal in their direction, overloading their radios. This is beginning what’s known as isolating the target…

2017 FCC Rule Changes for FRS Go into Effect 9/30/19

Back in 2017, the FCC reviewed the personal radio services which include FRS, GMRS, CB, MURS and more and made changes to the rules. Many of those new rules go into effect on Sept. 30, 2019 — or in two weeks from this publication.

Here are the main changes to the rules going into effect:

  • No FRS/GMRS combined radios can be sold after that date
  • No hand held radio capable of operating in both FRS and any other licensed service can be manufactured or imported
  • No voice obscuring radios operating in these services may be manufactured, imported or sold

Here are some additional details

Things to know

  • Summer Gathering is held at Valley Camp, 49515 SE Middle Fork Rd, North Bend, WA 98045, If you enter this into a GPS and it is something other than a newer model Garmin it will take you to a different place so be aware and check your Google Map to find the exact location. Sadly the Tom-Tom GPS has a bad database and will take you on a wild goose chase. Better yet use these coordinates:   47.46805° -121.68081° For us location precision nuts the GPS coordinates for a point near the center of camp are: 47.4662216  -121.6804046  (Highly accurate GPS control point)  The WA7VC Banner may be out near the entrance, this will confirm you have arrived.
  • When entering Valley Camp please stay to the left and keep your speed at or below 5 MPH keeping an eye out for small critters and humans crossing the road and remember only you can prevent speed bumps.
  • Cellular coverage is spotty in camp. If your phone has WiFi calling capabilities the Valley Camp WiFi will support that service. WiFi in camp covers just about the entire camp however due to bandwidth limitations of CenturyLink’s equipment the system can not support video streaming, or OS updates. Please turn off Automatic Updates on your equipment so there is plenty of bandwidth for Web searches and emailing for everyone. Please do not use WiFi extenders or personal hotspots as these interfere with the camp WiFi. Network login information will be available in the pavilion.
  • Valley Camp is a No Smoking facility. If we see you smoking we will assume you are on fire and take sudden and appropriate fire fighting measures.
  • If you have a comfortable folding camp chair bring it along. The picnic benches are 60 year old very hard 2×12’s.
  • Pets – If you must bring your pet it has to stay on a 6 foot leash and stay connected to you at all times. We also expect you to clean up after it and be very careful feeding it, any spilled food attracts wild animals, some you don’t want to meet at night.
  • Parking while at the event – Please be aware that not all RV’s in the campground are attending the Summer Gathering so please do not block vehicles parked in front of RV’s. Parking is best accomplished west of the RV area along the road towards the Lodge and Roundhouse.
  • The Summer Gathering is funded only through donations of the attendees, no outside organization financially sponsors the event. Please consider what this event is worth to you and donate appropriately. In the past it was suggested that $25 per day for the event was appropriate, adding $30 for meals on Saturday, and $20 for meals on Sunday.  There will be several places to leave your donations, the main one being the green MAILBOX marked DONATIONS in the shelter and if you would like to make a donation using a credit card see Teena.
  • Valley Camp is the conduit for all donations and it is a 501(c)3 not for profit organization.
  • Online donation opportunities can be found here on the first page:  https://valleycamp.org

More information and a signup survey coming soon!

See you in a few weeks,

Brushbeater: A Modern Look at Guerrilla Radio Equipment

NC Scout at the Brushbeater blog has a brief article up looking at some FARC equipment – A Modern Look at Guerrilla Radio Equipment.

Watching a recent media piece on the FARC, I noticed a few shots of their radio equipment they were using to communicate between camps.

farc817.jpeg

Look familiar? Its a Yaesu 817 being run from a Sealed Lead Acid battery. Here’s a better shot:

FARC817_2

Interesting layout by one of their RTOs:

FARC817_3,jpeg.jpg

The old 817 appears to be very popular among the communist guerrilla group, and if I had to guess (based on their geography) they’re using VHF single sideband and HF NVIS to relay camp-to-camp through the mountains where they operate.

I imagine they’ve learned a lot in the communications department over a half century of civil war, and it looks like they’re keeping it simple, analog and robust.

Here is some background for this year’s T-REX:

This years T-REX is primarily centered around a cyber attack on PLC’s (programmable logic controllers). These small devices provide computer control of many of our industrial and infrastructure mechanical devices. You may remember the “STUXNET” virus that struck Iran’s nuclear program. The virus attacked PLC’s that controlled the speed of uranium centrifuges and caused them to spin out of control resulting in failure and damage to the centrifuges. It is hypothesized that the STUXNET virus was introduced into the Iranian computers through a compromised USB drive.

In addition to the cyber attack on the PLC’s, this T-REX will incorporate other types of cyber attacks into commercial infrastructure and ATM’s, medical devices and communications services.

The following link will give a good overview on how to prevent cyber intrusion into infrastructure devices and is worth reading. Overview of Cyber Vulnerabilities

ARRL: Hurricane Watch Net Keeping Eye on Tropical Storm Barry

From the Amateur Radio Relay League:

Hurricane Watch Net (HWN) Manager Bobby Graves, KB5HAV, said the net is “keeping a very close eye” on Tropical Storm Barry, which could develop into a Category 1 hurricane. The HWN has announced no plans to activate, however, and remains at Alert Level 2 — monitoring mode.

At 2100 UTC, the storm’s center was 90 miles south of the mouth of the Mississippi and some 175 miles southeast of Morgan City, Louisiana. The storm is generating maximum sustained winds of 40 MPH with higher gusts and is moving to the west at 5 MPH.

“Although hurricane watches and warnings are now in effect, the National Hurricane Center states that Barry could become a hurricane prior to landfall,” Graves noted. “Even if Barry does not reach Category 1 hurricane status, wind gusts to hurricane force are possible in the warning area. Regardless, if Barry becomes a hurricane or not, this system is looking to be a major rainmaker.”

Forecasters concur that the storm will continue to intensify until making landfall. A danger exists of life-threatening storm surge along the coast of southern and southeastern Louisiana. The storm’s slow movement will result in an extended period of heavy rainfall and the threat of flooding along the central Gulf Coast and inland through the lower Mississippi Valley through the weekend into early next week, forecasters said.

 

Here is the standard HWN activation plan:

When activated, you will find us on 14.325 MHz (USB) by day and 7.268 MHz (LSB) by night. If propagation dictates, daytime operations will be conducted on both frequencies simultaneously. Why do we state these frequencies without a plus or minus amount? Because those who are operating using marine radios have to program in the frequencies – marine radios do not have a VFO or RIT. Furthermore, these two frequencies come preprogrammed into many marine radios. Many non-hams listen in via shortwave radio and know this is where to find us when we are activated…

NOTE: During any Net activation, operations on 7.268.00 MHz will suspend @ 7:30 AM ET to allow the “Waterway Radio and Cruising Club Net – WRCC” (aka, the Waterway Net) to conduct their daily morning Net. If required, due to poor daytime propagation on 14.325.00 MHz, operations on 7.268.00 MHz may be required at the conclusion of the Water Way Net, generally around 8:30 AM ET.

Whenever the Hurricane Watch Net is not active, you can hear the latest information on 14.300.00 MHz.

As a special note to those who monitor when the net is active, we ask that you please honor our request for you remain quiet unless specifically called upon for assistance.

The 2019 TEOTWAWKI Readiness Exercise will be held over the weekend of July 26 through 28. Save the date now to save yourself later. The AmRRON T-REX is a radio communication disaster exercise, but you can follow along with the disaster scenario even if you don’t have a radio. (Click here to see the 2018 T-REX archives.) For AmRRON and its members, the exercise is a functional to full-scale exercise. If you wish to participate on your own with your local group, you can work it as a walk-through, tabletop, or more as you see fit.

AmPart: ARRL Field Day 2019

Johny Mac at American Partisan has a nice short article on this weekend’s ARRL Field Day and why people who want to be prepared should get into amateur radio as well as how to do so.

…the ARRL (American Radio Relay League) Field Day will commence at 1400 hrs. Saturday June 22nd and run till 1400 hrs. Sunday. Field Day is a big event for all Amateur Radio operators and clubs across North America.

Looking at the ARRL site they write:

“Every June, more than 40,000 hams throughout North America set up temporary transmitting stations in public places to demonstrate ham radio’s science, skill and service to our communities and our nation. It combines public service, emergency preparedness, community outreach, and technical skills all in a single event. Field Day has been an annual event since 1933, and remains the most popular event in ham radio.”

If you have been meaning to get into ham radio take the time to attend one of the many field day events put on by your local area club. To find a Field Day event do an interwiz search for your counties Amateur Radio club. Once found go to their site and if they are participating in the event, I am sure there will be an invitation to the event. The ARRL also has a location finder located here but beware that at this time the ARRL may not have all of the locations for the event uploaded. I would try both – Interwiz search and using the ARRL locator.

ARRL continues to explain the objective of the event as…

“To work as many stations as possible on the 160, 80, 40, 20,15 and 10 Meter HF bands, as well as all bands 50 MHz and above, and to learn to operate in abnormal situations in less than optimal conditions. Field Day is open to all amateurs in the areas covered by the ARRL/RAC Field Organizations and countries within IARU Region 2. DX stations residing in other regions may be contacted for credit, but are not eligible to submit entries.”

Okay, with that all reported, how many American Partisan readers have their amateur radio ticket? If you do not, it is time to stop adding to your gun safe and seriously think about working towards getting it.

I have a very good friend who is a prepper, not part of my group, who keeps telling me that he has a transceiver and when the SHTF happens he will figure it out – Bovem de stercore!

It’s like running a gun, practicing patrols, or testing TC3 techniques; you will fall flat on your face unless you learn now before the bullets start flying…

American Partisan: Home Brew – NVIS Antenna

Johny Mac at American Partisan has an article up at American Partisan on making your own NVIS antenna. A near-vertical incidence skywave (NVIS) antenna is used in the high frequency (HF) spectrum from around 1.8MHz to  10MHz in order to cover an approximate radius/range of 300 miles. HF is usually used for long distance communication around the world, and most antennas are built to maximize range, but those antennas can often cause the radio signal to skip or make a gap in the range from about fifty to three hundred miles.  The NVIS antenna redirects the radio signal in such a way that it covers that gap at the sacrifice of the longer distance contacts. This makes the NVIS antenna ideal for communications during a regional disaster.

If you do not know what a NVIS antenna is and why it is a great addition to your antenna farm, go and read these four articles. The first being from NC Scout titled, Near Vertical Incidence Skywave – Simplified, then NVIS I, NVIS II, and NVIS III authored by Key Pounder and published on NC Scout’s site, Brushbeater.

At a 100,000-foot level though, a NVIS antenna is a dipole antenna that has a steeper transmit angle than a traditional horizontal flat-top dipole antenna and is located closer to the ground at between 8 to 15-feet Vs. a traditional 1/4λ height; let’s say 30 to 60-feet over tera firma. This allows you to transmit to other stations closer to your AO that you may skip over using a flat-top horizontal dipole antenna. Think of the skip bounced off the ‘F’ layer of the ionosphere being 25 to 50-miles Vs. 200 to 300-miles. The German Army developed this procedure during WW II to communicate with troops via the airwaves closer to the transmitting station.

Traditional dipole antenna radiation Vs. NVIS radiation

I started out building my NVIS antenna using the directions posted on the DX Engineeringsite as my blue-prints for the project. Although you can buy a kit from DX Engineering, I had plenty of hardware around the redoubt so I decided to save a few bucks. Below is my Mise en place for this build. Hams are the true scroungers of this earth…

AmPart: Directional Antennas for the Small Unit, Part I and II

NC Scout at American Partisan has started a series of articles on antenna theory called Directional Antennas for the Small Unit. If you’re just getting started in radio communication, or you’ve been using it for a while but haven’t spent much time getting to know your antennas, this is a good start.

Directional Antennas For The Small Unit, Part 1

One of the biggest misconceptions behind communications security revolves around misunderstanding not just the role of the equipment but also how it functions. A big part of that is the basics of antenna theory. For most radio seems to be a plug and play kinda deal- it either works, or it doesn’t. Antennas are a type of voodoo magic and the solution to security is electronic encryption. Except it isn’t, and doesn’t do anything except mask what you’re saying, but not the fact you’re saying it. Guerrillas must rely on not being detected- and no matter how high tech you think you are, it’ll not solve a tradecraft issue.

The reality is that we’ll be working with equipment that is common and off the shelf- no matter how much we want those microwave NSA-encrypted troposcatter radios made of unobtanium, a big part of local networking is done via plain old VHF and UHF amateur and commercial gear that’s common. Guerrilla communications have to be harder to detect. And at the strategic level when building an underground network, you have to understand how to plan. Even with the cheap equipment most of you likely have, incorporating a level of planning into your local communications will yield a much higher level of security and success. Knowing and understanding directional antennas becomes a key part of that planning, and as we cover in the Advanced RTO Course, there’s several options that each get the job done.

Directional Antennas such as this Yagi seen here offer security by ‘beaming’ our transmission in the direction its pointed.

Directional antennas accomplish two goals for us. First, generally speaking, if you’re not in the direction of the transmission you’re not going to hear the traffic. Because of this it offers a big advantage in the security department. If two directional antennas are transmitting toward one another, they’ll be able to communicate with the only people hearing the full conversation being in the middle of the two people. The second advantage is that instead of all our energy going in all directional at once, as with an omnidirectional antenna, a directional antenna sends the same amount of radiated energy in one direction- greatly increasing our range and signal strength in that direction, so we won’t need nearly as much power to accomplish to reliably communicate over a distance you might not have thought otherwise possible…
