[K1 vs. KX1] If only they had a K1 with a DDS VFO and SWL! Or a surface-mount KX1 for even smaller size! Elecraft should combine the two radios and call it a KX2.

Morse Code / 'Morse Code as a Language'
October 28, 2015, 10:16:43 PM
https://www.youtube.com/watch?v=9Kg5FDhO6uU&list=PLdwkbjBNJkwLazdN5TqJ1y9uGnoVpsfQw&index=1

This playlist was put on YouTube last week, perhaps of use to some of those who are learning Morse Code?

QuoteHi everybody. Justin here from the Morse Code channel.

I'm doing this video to introduce this new playlist which is learning 'Morse Code as a Language'. Morse code really is its own language, with its own words, grammar, structure, conventions, slang, and so on.

I'm going to present short dialogs between two hypothetical people. I'll be sending Morse code using different tones for the different people. After the dialog, I'll break it down, what they were saying, including things to look out for, and things specific to Morse code.

The playlist is going to be geared at newbies and intermediates. I assume the listener knows at least some or all of the letters and numbers. It would be great if the listener has a Morse code key they can use as well to practice, or an app, or computer program, but one of the practical things about Morse code is that you can even just tap with your finger, say dit and dah with your voice, etc. to participate.

I would encourage people to NOT use computers or apps to decode the Morse code you hear, but rather keep it a skill, a human activity, as much as possible. I think you'll learn more Morse code this way.

And we'll go from there!

My background is I've been interested in ham radio and Morse code since about 2013, and have been doing Morse code practice on and off the air since then. I upgraded to my Extra license a few weeks ago. I love languages in general, I can speak some Espanol (Spanish) and Putonghua (Mandarin Chinese).

Thanks for having an interest in languages, Morse code specifically, and checking out this channel, and this new playlist 'Morse Code as a Language'.

I will see you next video, bye bye.

Finally, no more depending on batteries or solar power or fossil fuel generators?

Portable wind turbine has sparked a craze and lets you harvest renewable energy almost anywhere

Janulus, a company based in Minnesota seems to have nailed a need that society has been craving.  They have built a portable wind turbine/battery combo that can charge your smart phone or your electric car.

The turbines come in one of four sizes and strengths.  The smallest, weighing in at 1.4 pounds, will give you 50 watts of power.  They scale up in size from 50 to 400 to 1,000 and finally to 2,500 watts, the largest of which can still fit in the trunk of your car.  The Kickstarter for these new models exploded on day 1 and has almost reached their goal of $50,000 as of this article being written.

General Discussion / A 'magic tent' for mountaineers?
September 28, 2015, 10:02:21 PM

QuoteAn "all-in-one" shelter system has been developed for mountaineers. Inside the shelter conditions remain comfortable whatever the weather outdoors, thanks to a sophisticated dehumidifying system and a fine-tuned temperature control mechanism.

I have been waiting for something like this to replace tents and sleeping bags. Must be fine for QRP / SOTA expeditions into the mountains? Maybe also for certain other contingencies?
