Death By Microprocessor
« on: September 05, 2019, 10:51:04 PM »
Well, not 'death' actually, more like 'DEAF by microprocessor'. 

We all know that radio communication in voice is quite power hungry, so Watt-for-Watt, digital modes are more robust in tough conditions.  Of course, Morse code sent via CW is extremely robust, yielding between 13-18 dB 'system gain' compared to voice modes, depending upon who's math you're using. 

The timing with this 'deafness' is 'educational':  About the time that Hurricane Dorian , a category >5< HURRICANE was pounding Bermuda and forecast to come up the coast and do the same to us, I received a Windows update, after which my laptop would not operate.  I went to SAFE mode, and it worked for a little while, then nothing....  This is the ham shack laptop with all my cool radio gimmicks on it, including weather satellite software to download my own images - directly, WINLINK (for emergency status checks with family and friends) & etc.  Windows is still deader than a bag-of-rocks to this day, until I have time to reload Windows from disc & all the software , then reconfigure it all.  I am in no hurry.

Why am I NOT in a hurry to fix my laptop so that I can communicate? Because my straight key and my 1939 McElroy 'bug' work flawlessly, cannot be virused, dDOS'd , have no 'back-door' vulnerabilities, and never have updates and yet work well below the noise level, require ZERO power, leaving only my transceiver(s) with their many battery back-up systems, which I am well prepared for. I have to ask myself:what would I do, if I had never learned Morse, and had to DEPEND upon a computer to communicate for me? If we loose power for the long term  , and iI decide to send 'health & welfare' messages to key friends, I can easily do that in Morse code, either casually through random hams outside of the area, or as formal message traffic via the various National Traffic System / RRI Morse traffic nets. And I can do it with very little power in CW - very, very little power.

A skill like Morse code will serve you for life. Skills take-up no room in your rucksack, weigh nothing and can be enhanced with a cup of coffee,

and brother, do I love good coffee!

Fortunately, Hurricane Dorian has dropped to a -still dangerous- category 2, and it's track indicates that it will only offer this area a glancing blow as it heads-out to sea. At least, that's the forecast. I'll know more tomorrow when I'm looking at it, or not.
