Implementing a mental dit/dah decoder + lookup table is the shortest path to being able to decode written CW ` _ . ___ _ ` but it will cause you problems trying to receive faster CW since you can't count, assemble, lookup fast enough to receive at more than 5-8WPM. And even then you are generally doing "keyboard copy" where you write down the letters as you hear them and then go back to actually read the message you received later.

If your goal is to be "conversational" in CW I suggest you crank up the character speed until you are not able to count individual dits/dahs anymore. This will probably be somewhere in the 25-35WPM range. The goal is "instant character recognition" where you hear the sound/shape of the entire character rather than counting elements, assembling them in your head, and doing a mental hash lookup on the result.

If you have trouble receiving or copying down the 5letter groups at this speed resist the temptation to add "farnsworth" spacing (extra gaps between letters). Instead increase the word spacing until you have enough down time in between to get everything copied.

You have a good source for this? I see claims like this every time a discussion of this sort and they rarely come with any citations.

"The legal definition of assault is an intentional act that gives another person reasonable fear that they'll be physically harmed or offensively touched. No physical contact or injury has to actually occur, but the accused person must have intentionally acted in a way to cause that fear."

Such "Oral History" articles were quite popular for a time* and the fist time I encountered this article it still had its original title. I'm sad that it was not retained since the url now gives away the punchline.

I think a more efficient solution would be series-hybrids with small onboard generators for range extension. Minimize weight/cost of the battery pack while maintaining the ability to drive cross-country without frequent charging stops.

The US rail network also >2x longer than Europe[3] (360,000km vs 151,000km).

Most derailments are in train yards. Few cause injuries, fewer cause deaths, and only a handful involve hazardous substances. I don't say that to downplay the mess in OH/PA, but just to make sure the base-rate is understood.

And if you want to compare to europe it looks like US freight rail volume is at least 6x as large. Also no idea if/how they count "fender bender" derailments in switching yards. US standard is >$12k in damage according to TFA.

"Stationary Low-Power Reactor Number One, also known as SL-1 or the Argonne Low Power Reactor (ALPR), was a United States Army experimental nuclear reactor in the western United States at the National Reactor Testing Station (NRTS), later the Idaho National Laboratory, west of Idaho Falls, Idaho. It experienced a steam explosion on the night of January 3, 1961, killing all three of its young military operators, and pinning one of them to the ceiling of the facility with a reactor vessel plug. The event is the only reactor accident in U.S. history that resulted in immediate fatalities.

I used the hamstudy website almost exclusively for getting my license and was able to pass all three tests (General, Tech, Amateur Extra) in one sitting. I had to set for a physical test at a local club's monthly meeting, but now organizations like GLAARG are proctoring remote tests via zoomso you can gest more or less 'on demand' from home.

appending units to identifiers helps, but it relies on a developer's eyeballs to spot any errors. It would be infinitely preferable if the type system would simply enforce this for you and developers not have to expend cycles reasoning about this stuff themselves.

The decoding algorithm uses some amount of Bayesian probabilities to decide what the proper decoding of the incoming signal is: http://ag1le.blogspot.com/2013/01/towards-bayesian-morse-dec...

$1068 at 85% efficiency is $907 "effective" heating dollars. $971 at 94% efficiency is $912 so that passes a basic sanity check.

The major improvement is efficiency c es from runnimg higher volume at lower temperature differentials. This allows the "cold" side of the furnace/boiler to condense the water vapor in the combustion gasses and capture its latent heat.

I built a few units similar to this (https://i.pinimg.com/originals/43/f8/d6/43f8d64f96ae537698a4...) to hold all of them.

I settled for small "coin envelopes" labelled with pen and placed on end in a deep shelf bin.

The developer also built ExamTools which many groups use to administer remote license exams. You can find sessions here: http://hamstudy.org/sessions

Be sure to check several. Receive capability is not the same across stations or between frequency bands on the same SDR.

I'm reasonably cynical about lots of things, but I would be absolutely shocked if a pharmacist can give you 90days of pills when handed a 30day (no refills) prescription.

I don't know about "most". Current Honda[0], Toyota[1], and Chrysler[2] vans are still up to the task.
