We have a MAJOR Hurricane approaching (It's a CAT 5 right now)  .  If you ever wondered how difficult it is to capture weather satellite images without the internet, it's not difficult, but does require the software and a bit of practice. There are MANY YouTube posts with excellent instruction about this, so I will not repeat what they've done. 

Here is an image received within the hour using an inexpensive SDR and no automatic satellite tracking or LNA: (attached)

Excellent short article from a former Marine and his HF dilemma and solution.

Once again, I enjoyed a nice chat in Morse with AH6V who lives on Hawaii.  Listening to his previous conversation, he mentioned that he is 45 miles from the volcano, so no trouble. Electrical power is no issue for him, because he has been living off grid for decades.  His antenna is a dipole, high and in the trees and my antenna is not at all good for long range, being a full wave , horizontal 80m loop up only 5 meters at the support poles, sagging to 3 meters at some points in between.  We discussed his large solar power system, which powers even his refrigeration & etc. -vs- my small sailboat sized system and the work shop/ham shack that it powered. 

Radio is simply amazing and the BEST 'communications computer' is your brain.

When I was a boy (shortly after the Earth's crust cooled...) I had the great privilege of studying Judo and later Ju Jitsu under some very good instructors - true masters, before that term became en vogue and horribly over used.

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; not me. Now I am old, so opening a bag of coffee makes me tired, but I don't mind: I love good coffee. As I read more about the origins of Japanese martial arts, Judo in particular, I came across a quote that has stayed with me for life:

"Maximum effect, with minimal effort." - Jiguro Kano

To some people, that's an excuse for laziness : it is not.  To others, it is an 'attack' on their delicate egos, which are tied to things which they bought at great expence in an attempt to have internal peace, no matter how ineffective and/or in efficient those possessions are.  To back woods radio people, this makes perfect sense.  When away from the "FREE" electricity of city A.C. mains, you must be efficient in your use of power. For hams, this is largely seen in proper time/frequency selection and MODE.  It's a well documented FACT that Morse code (CW) is very much more energy efficient than voice, for conveying the same 'intelligence' ; 13-18dB more efficient, depending upon whos math you're using, but at the least, that's 20 times more power needed for SSB over CW. Translate that into batteries, chargers, heatsinks accessories and you'll see that Size, Weights & Power (SWAP) is huge compared to a QRP CW rig with the same relative capabilities , and much more expensive.

Simplicity: I was recently at a demonstration of emergency communication held in a pasture.  There were cafeteria tables, many laptop computers, some networked, A.C. power, cables all over the place and the list goes on.  When I left 24 hours later, the only successful comms as of that time was QRP handsent CW using my KX2 and a low dipole.  All CW skeds were achieved right on time, with very good results.  Naturally, as those laptops were also running NOT on internal batteries, but plugged-in to A.C. power, their RFI ensured that any comms were likely to be unsuccessful.  All that power, software, training experience and MONEY - very inefficient. These were intelligent, dedicated people , many of whom are experts in various professional fields. However, a single band QRP CW rig costing almost nothing, could do much more, for much less and fit into a pocket.

The lesson - do what works, and forget the colorful advertising that tells you that you must be dissatisfied with your life and buying their 'stuff' will make you content, successful and adored by the opposite sex: it's all nonsense.  Use whatever is as simple as possible (but not 'simpleR' than possible) and works reliably. for my experience, that is HF CW. If the 'necessary' accessories like computers, panadaptors, wifi routers, and more are required, then THEY must be added to your calculation s of SWAP.  That's a LOT of Size , Weight and Power to drain your recharging and to carry around, It multiplies the set-up and (trouble-shooting) time , tremendously.  I had two 'wires' coming out of my rig: coax to their antenna and my ear buds - to eliminate their constant yelling at each other.

Like judo: efficiency matters. During hobby times, it's basically stress free. During an emergency; it's essential.

I like watching Gil, Julian, Spanish QRP cw, Peter Parker with delightful videos on youtube. They go someplace, set-up a station in a few minutes and then are having fun operating and learning on the air. Enjoyment,  fresh air and into the LOW RFI outdoors: all good.

ANSWER:

As ham radio is being changed from a technical and communication service to a "radiosport" hobby, many aspects have degraded. One which is being pushed recently is to not really learn to copy Morse but rather to gain speed by quessing what the other station is about to send . I have one word for this : WRONG.  A fellow I know and enjoy his exploits was recently passing this off as good advice , with idea like "if the other station sends MALM... I know his QTH is MALMÖ." And stuff like that   Again , I say wrong.  If contest points is the only point, I suppose it does not matter, because contests are meaningless and by nature; disruptive of actual communication.

I just had a bad -partial- CW contact this morning with a code-guesser . When starting a conversation about the usual weather and plans to go to the park later, he come back with how great my signal is from the park. - uh, you're guessing ,'not copying.  Name - wrong, location -wrong most of these were similar in the first few letters. He was not copying - he was guessing. It was not a conversation .

Nobody outside of a professional telegrapher expects 100% copy.'However, this "guessing is good enough" attitude while perfectly fine in the artificial game world of contests, makes an actual conversation impossible. Fortunately , my transceiver has a button to solve this : the OFF button. I made an espresso and read my book in the sun outside.

Please - strive to copy code. Turn off the code reader "feature"'and use your mind. Morse can be very satisfying, and guessing is not the same as copying.
