Licensing / Re: Getting License or NOT

Hello Branko. Don't be too hard on yourself. 20wpm is not easy for me either. Try listening between 7000 and 7050 kHz, also 3560 and 14060 kHz for CW. When you go for the license test, try for both Technician and General at least, and if you pass General, and you will, try Extra.

Thanks Bob, washers are on my shopping list! I need butterfly nuts too, but can't get standard threads in France. Thankfully there is the Internet!

Joel, make sure you tell Dale P. Where you heard about it ;-) maybe he'll send me another antenna to test! I bought this one...

Hello,

You might be able to transmit under your call sign using a prefix, but the US license is VERY easy to get. I passed my Technician, General and Extra exams in the same session, for $15! I bought the three books from the ARRL and studied one chapter per day in each book. Since the chapters are on the same subjects, you study three chapters per day on the same subject from the three books. You can find the dates and locations of the exams on the ARRL web site. The people doing the exam are ham operators authorized by the FCC. The exam usually takes place at a local radio club.

When I lived in Florida there was a LOT of activity from every state, and a lot of Morse code. This was only two years ago. I am surprised you don't hear much... Maybe your antenna or you are not listening in the right places.

I'd say that you should get the US license. This way you can practice. You should be hearing lots of traffic. Make sure you listen on the right frequencies and check your equipment.

Where are you located?

Hello Rich.

I usually glue my wire to a pen cap so that I can slid it on top of the fishing pole I use. This way it can easily be removed. It's not very secure, but it works for me. You can use something a bit longer, maybe a few inches of plastic tubing... I also sometimes just use a piece of string. See this video:

Excellent Ray! :D

Learning judo, as an American boy steeped in the idea that rage and bulging muscles were everything, I soon learned that quiet, focused power, applied exactly where and when required was far more effective and very efficient.  As a result of a few years of training, back then, I could fight multiple opponents and rarely tire - because THEY were burning a lot of unnecessary energy;

It's funny how we arrive often arrive at the same conclusion via different routes. As a teenager, I practiced a few martial arts for which the abovementioned bulging muscles, tension and aggressiveness were emphasized. Fast forward a couple decades and I end-up in a small group of camo-pants wearing guys training under a former Spetsnaz. He tells us to relax and breathe, and be emotionally detached from the action. It's Systema... The Cossacks got it right...

Another example: Take a good'ol .45 Colt bullet, 285 grains of lead, and shoot it in a modern replica at 1000fps (ouch!). Now get a big Ruger revolver and try at 1400fps... Guess which bullet is going to penetrate farther? Yep, the slower one! And some people on online forums say the old .44-40 isn't enough to kill a deer ::) Same flawed reasoning... They must buy the latest "magnum," at $3/round. The darn deer isn't going to be any "deader."

While the physics are different, more force isn't always better.

I have wondered a few times if I needed an amp. The answer has always been no. I don't think I'll ever use more than 30W for SSB and 5W for CW, why? A good antenna is enough, and like Ray says, choose your battles. I am also thinking about getting better coax now...

Ray, do you think these people at the emcom event learned something? Or are they just too brainwashed to even see the elephant?

Right now I am experimenting with 2m SSB, which to my surprise also works quite well using only a few Watts! Radio will always amaze me.

I have learned a few things since 2012... Like not to use a short 3m whip on 40m, or to use verticals for 30m and up, and horizontals on 40 and below... It's a long list of learn-by-experience lessons. I have also carried by gear for weeks at a time, and OUNCES matter! Even a 2Ah SLA battery can be a no-no. Ultralight isn't always needed, but there is always a line.

As I always say, most emcom people never think that, just maybe, they'll have to carry their gear, on foot. It's one thing to arrive by car and park right next to your nice camping area, quite another to hike a mountain, even a small hill, SOTA style, with your heavy batteries and rigs. It's not practical training. Just like some martial arts where you're supposed to learn to defend yourself but you are prohibited from hitting the face of your opponent or even make real contact in some styles... What's going to happen when it really hits the fan?

Thanks again Ray, great post!

Gil.

Could the rod have anodizing that needed to be sanded/filed off?

Hi Bob, I did sand it. Either the brazing rods I got from China are crap, or it just wasn't hot enough, maybe both. I need to find someone locally who can help me out... I should have used brass or copper rods and be done with it...

That one was also made by Youkits. You'll have a lot of fun with it. We should try a contact some time.
