I found this post on a blog. It is a long post, but it is a worthwhile read. I removed most of the images, but you can see them on the blog. http://thoughtsfromfrankandfern.blogspot.com/2019/03/opsec-communications.html OPSEC Communications Hello Everybody, Frank here. It's the weekend and we had a great rain last night. Now the freshly tilled garden would be just the place for making mud angels. For you Yankee types, some of you would still be calling these snow angels, but here in the south we actually call it mud wrestling. See, we have a problem here with communication. Some of you think snow tires and some of us think mud tires. This previously driven article is about communications. It's titled OPSEC which means operational security. This article is five years old, but the information is still the same today. We NEED to be able to communicate with our neighbors. No, it's not the kind of communication that you say you can't have with your teenage kids, you know, 'we just can't communicate'. The type of communications mentioned here is the life and death type, where you NEED to be able to talk to the person down the road. The first picture down below is of Nunam Iqua, Alaska. Fern and I used to live there, it is located at the mouth of the Yukon River on the Bering Sea. For you curious types, the zip code is 99666. Google maps will take you right there. The article is about radios. This is not so much about ham radio, actually, it's not about ham radio at all. It's about the across-the-counter type of radios. But, ham radio is a good idea, it vastly expands your options. If you are of the level that you find reading Frank and Fern enjoyable, then you should have no difficulty with the first two levels of amateur radio testing for licensing. Ham radio can be very, very expensive, or it can be quite inexpensive. It's kind of like flying a remote controlled airplane, now days commonly called drones. I didn't realize some of those drones are as big as a jet, a big jet. But I'm drifting here. Something to remember. Anything that is said on a radio can be heard by someone else. I used to teach my teachers, if you don't want someone to read something, then don't write it. Same applies to radio. Anything you say can be heard by that drone flying in the air. Think about it. Hope you enjoy the article. Have a great day. And get ready. It's very near. We'll talk more later, Frank Originally published January 4, 2014 Once upon a time, there were two people that lived in far bush Alaska that could see dark clouds on the horizon. These two people, knowing what dark clouds meant, started to prepare for a serious storm. As the clouds got closer, and the sky darkened, these two adventurous souls packed up all their gear and relocated to a somewhat safer location. Even though these people escaped this particular storm, the storms followed them to their new location. And the storms have continued to grow bigger and bigger and bigger. Okee-dokee everybody, back to reality. My first experience with radio communication in the modern world we live in now, was with two little walkie-talkie radios. Fern and I were leaving Alaska and we were going to drive to southeast Oklahoma. Through a large portion of this trip there is no cell phone service. Since we were traveling in two separate vehicles, each pulling a U-Haul trailer, I bought a couple of the above mentioned handheld walkie talkies from Cabela's. And that's how this radio story started. That was five years ago, and here we are today. I knew nothing about rechargeable batteries. I didn't know that you could recharge batteries while you're driving down the road. So we used eight alkaline batteries a day. You see, Fern and I are an odd couple. We actually like each other and enjoy talking to each other, so the radios came in real handy. So, after our little trip, which took eleven days, I discovered the benefits of rechargeable batteries. 110/12VDC charger So, when we got here, we put the radios away for a while. I'm not sure exactly when or how or why, but we started using them again around our little farm here. And like many things in life, I had to experience a largelearning curve. Well, we started using the little radios again and learned about rechargeable batteries. I decided I wanted extra radios. I went online, found a couple, and not paying attention, realized they did not use a AA battery. But, instead these new radios used a AAA battery. This was not my plan, but I didn't have the knowledge to know the difference. So, now I need AA and AAA rechargeable batteries. Well, this system worked out okay. I found a place online to buy batteries that I like. And I still use this same place, by the way. So, now I have a hand full of radios, two different types of batteries and the system is working pretty good. But the three AAA batteries will not stay charged near as long as four AA batteries. So, I decided to buy more radios. That's when I started using the Midland GXT1000 and 1050. They are the same radio, one is black the other is camo. I got lucky when I bought this little radio, because it did something I didn't know it would do. It comes with a rechargeable battery pack, which looks just like three AA's put together. But it says it will take four AA's, and it will. If you take the cover off and take the battery pack out, you will see that there is an extra slot for a fourth battery. The cool part is, these four AA rechargeable batteries, will also charge in the charging cradle that the radio came with. Here's where I got lucky. Midland makes a bunch of radios that look just like this, that have the same set up with the same battery pack, but the other ones will not recharge the four rechargeable AA batteries while in the cradle. As the learning curve increased here, it was obvious that not all of these radios charge the same way. So, a bonus feature, because later on I bought some other Midland radios that looked identical, but I could not charge the four AA rechargeable batteries in the cradle. So much for that issue. I know these little radios are advertised a certain mileage. But that is under perfect conditions. So, remember, these radios are line of sight, and if you need more information about how the radios operate and their properties, go to Frank's Radio Communications page. These are good radios, high quality and they work well, and they did the job we needed around the farm. I'm still, at this time, not into ham radio. I tried to get some of my friends and neighbors to get some of these little radios so we could keep in touch. No one was interested in this form of communication, and years later, they're still not interested. That pretty much took care of the home issue. Now I wanted to be able to reach my wife by radio 30 miles away. Bigger issue. We tried CB radios with SSB and due to the properties of the CB radio, it just would not work. I live in hill country with small mountains. So one day, looking at a retail radio site, I noticed a programmable commercial radio. Did a little bit more research and realized that these radios would broadcast on the same frequency as my little walkie talkies. That is when I started to realize about different frequencies. You see, a CB radio is around 27 MHz. My littlewalkie talkies are around 460 MHz. These new little commercial radios are handheld and they would broadcast on the VHF band which includes most local police, fire and ambulance. It was also good on the ham radio frequencies, which at that time, I cared nothing about. All the ones I just mentioned, police, fire and ham, are in the VHF range, that's around 140-155 MHz. But these little radios would also work for GMRS, which is my little walkie talkie, at around 460 MHz, which is UHF. There is also another free public band called MURS, which is around 150 MHz. So, I tried these little handheld commercial radios and they worked great on this frequency. Some of these activities mentioned here, some folks will tell you that you cannot use a commercial radio for, and they are right. But as long as you are not bothering anybody, most people don't care. Also, remember that in an emergency, anyone can use any frequency if no other means is available. So, I put a couple of these little commercial radios, remember, these are handhelds, in our cars running legal power, and could talk to my wife most of her way to work. I dug out my old Radio Shack power supply, I put up an outside antenna, and used one of these little radios to talk to my wife all the way to work. The antenna outside of my house is what made the difference.
