+1 to the above. 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…

I'll put in a vote for: https://lcwo.net/ (Learn CW Online) If your goal is to be "conversational" in CW I suggest you crank up the character speed until you are not able to count …

My understanding of the system is that the plug is physically locked in the charge socket while the car is drawing current through the cable. Thus it is impossible for there to be …

More recent minivans will still fit sheet goods in the back, but they have started rounding off the lift gate (and consequently the opening it fits into) for stylistic reasons and …

A document I saw yesterday claimed that SVB had ~$160B in uninsured deposits.

PHEVs are certainly more complex, but a series hybrid like the BMW i3 only involves finding space for a small genset and some additional control software/electronics. I'm having tr…

That appears to be "road freight" not "rail freight".

I'd love to find a good number on the daily mileage of the median passenger car in the US. The average looks to be around 30-35mi/day but the median is probably a small fraction of…

Where did you find those EU-27 numbers? I am seeing something around ~400B ton-km. > "Rail freight activity in Europe, measured in tonne-kilometers, grew from 339 Billion tonne-km …

Some light googling gives me 390B kilometer-tonnes[1] in Europe and 1.6T ton-miles[2] in the US for 2019. So that is 6x the freight movement. The US rail network also >2x longer th…

Amateur radio is for 2-way communication only. No "broadcasts" allowed (with some _very narrow_ exceptions).

It isn't really clear in the video, but that is a 4 layer board and there is another ground plane layer elsewhere. The heater loop doesn't connect to any components.

My apologies. It appears Morse Expert is Android only, sorry. I tried to do a quick search on my way out the door earlier and was mistaken.

The "Morse Expert" App available for Android/iOS does a pretty good job of decoding CW 'in the wild'. It can adapt to different sending speeds and does a decent job with non-ideal …

What were you expecting to find? $1068 at 85% efficiency is $907 "effective" heating dollars. $971 at 94% efficiency is $912 so that passes a basic sanity check. The major improvem…
