Hello,

Anyone who thinks EMP protection is overkill should read this:

Sunflower, you make an interesting comment, and you are not the only one, about the perceived complexity of Ham radio. I say perceived, because it doesn't have to be. Although I am a programmer by trade, I do not like complex radios. I spend too much time as it is using menus and complex interfaces. I like my radios to have a volume button and tune button, and not much else! The least the better. More features does not make a radio transmit better. It does make it hear better sometimes, but bells and whistles are optional. My favorite radio, one I build myself, is the Elecraft K1. It isn't the simplest, does use menus and has a few knobs and buttons, but remains very easy to use, small, and has a very low current draw. Anything more complex, I shy away from. Let's face it, if I can't explain to someone how to use it in a few minutes, there is a potential problem there... I can't teach Morse code to someone in 5 minutes of course, but SSB (Single Side Band voice) radios can be simple too. Look at the MFJ-9440 or an old Atlas... That's the kind of simplicity I like. With the Tech exam being so accessible, why not? Sure, it's a pain to have to pass an exam and be "registered," but to practice, you need to get on the air. When the SHTF is not a good time to learn. You could use CB and learn a lot about antennas of course, but you limit yourself to one band that only allows long distance communications in the best of conditions.

By the way, other members can thank you for suggesting the "New To Radio" board, it is on.

Morse Code / Starting the Morse Code Board.
« on: September 03, 2012, 02:10:26 AM »
Hello,

I am creating this board based on my opinion that Morse Code might be the ultimate communication mode when it comes to prepping. Sure, Morse Code is hard to learn (for me anyway) and somewhat slow compared to other modes (though that can be argued..), but it has many advantages...

- Morse code can be used not only with radio but with visual signals such as light, laser, sound, touch, the detailed list would be long.
- Morse doesn't need a lot of power to cut through the ether.
- A telegraph system is easy to set-up using new or existing wire infrastructures and insures privacy.
- Is is inherently more private than voice modes.
- CW-only radios are cheap and small, with low current drain.
- With an appropriate key and earphones, it allows to transmit messages silently.

Feel free to add more...

I use two training tools to learn Morse Code: The ham Morse iOS application, and http://lcwo.net. There are many more.

In my opinion, Morse Code should not only be preserved but promoted in the prepping community at large as a great emergency communication mode.

ConfederateColonel, I agree about the importance of building communication networks in case of a "Postman" situation. The difficulty would be to establish somewhat of a standard.. II like the basic Morse radiograms. CW is after all a data mode and the availability of computers and the required software might be rather "spotty." I think that foremost, Morse should be not only preserved but promoted as the major SHTF mode. You can use it with radio, lights, banging things, visual signals, the list is endless. There should be a thread started on the subject, and I will do so when I have a minute, but if you want to beat me up to it, please do! I have a lot to do as is...

Hello Hayr,

I am new to Ham as well, but not radio or electronics. You don't need to be an electronics guru... I would suggest that you concentrate your efforts on learning about antennas, which I believe is the most important factor in getting a signal out. The rest of it will come later. As to tuber sets, I would not suggest them... First, because they use very high voltages and are dangerous to mess with if you don't know what you are doing. An unplugged radio can shock you pretty bad if you touch a charged capacitor by mistake. Second, they are very heavy, and mobility in my opinion is an important advantage in prepping. If you want to buy a cheap radio, look into old solid state rigs like the late Atlas radios, or anything between tube technology and surface-mounted components.
I personally used to be interested in the latest stuff with all the bells and whittles, but my opinion has somewhat changed. Now I value simplicity and ruggedness more. So, my best advise is to take your time in choosing. As to fixed or mobile, I prefer "portable." which is a third category. I want a radio that is simple, with a low current draw, light, small, that can be transported easily, even on foot. You have to give up other things to get all that, like power, but I think portability is more important. That's just for the minimum of course, you can always get that boat anchor later  ;)

Hello,

First I would turn on my 2m handheld on and start scanning.

Second, I would jump on 20 and 40m to check news from further away. People might not know locally or regionally about what is going on, but Ham in different states or even countries/continents might have heard news about the event...

I think both HF and VHF are a necessity.

Hello,

Do you need a license for these radios, or should we just not mention anything about that  ;)

Oh yes Scott, I agree. Emergency radio is not a profession though like being a doctor or a teacher.. It can be in some cases probably, but usually isn't. So, what is the motivation here? We have to be honest with ourselves when talking about serving a community. In many ways, of course, helping your community is beneficial to yourself and betters the world around you for everyone. I don't think however that people usually think that far. So, there are I believe two kinds of individuals that would be willing to pay to help others. Those who are smart enough to realize that they are creating a better environment for themselves and their families, or simply enjoy the hobby and want to do a little more while providing a service, but there is also the kind with an ego problem who crave recognition for their services (maybe not consciously). The later are the people I do not like. Not that they are prevalent, but they are around...

Thanks Frosty for that great link!

About CB, the problem is that a beam antenna is huge, and not everyone can or wants to set-up such a monster on their roof... A beam antenna for a 2m SSB radio is much, much smaller...

Hello,

I got a Yaesu FT-270R and I really like it. It isn't too complicated but has all the features you want. It is also waterproof, with is a nice feature for an emergency radio...

Hello,

The Ic-7000 sure looks great. 2A though is indeed way too much for battery operations. My K1 draws 55mA, K2, 220mA, and that's with the backlit LCD on, and the S-meter on as well. Even the FT-817-ND draws 450mA on receive, which is considered high..

Hello,

I am sure more experienced members will comment, but here are my thoughts... Had you mentioned 20 miles or 300, the choice would be easy. 45 miles, not so sure... If you used 2m radios, you would need some power and antennas up high. Yagi antennas would be best, but then you have to point them in the desired direction. SSB would undoubtedly work better than FM for that purpose. The problem here is that it gets a bit complex and costly for someone who isn't into Ham radio. A regular antenna at a good height might work. I would maybe get FT-2900Rs which output 75W. Not sure it would work though over that distance...
40m might be a better choice with an NVIS (Near Vertical Incidence Skywave) antenna. It might not work all the time, but mostly I think it would. A general class license is required though, but it isn't hard to get, and only one person per family needs it for the intended purpose. Of course, for real emergencies, a license wouldn't matter, but in the mean time you need to practice... For 40m on a budget, I would say MFJ-9440X.

Gil.

Well, I am glad to hear that kind of behavior isn't common in ARES. I am not saying all Hams interested in emergency communications are elitists. The attitude does exist however, and it is one thing that makes me raise an eyebrow when I see it. As to the classes, couldn't they also be administered by volunteers?
