Getting my technicians license has been one of those things that's been on my list since childhood.
Presenting: Amateur Radio Question Study for PropModule (PSM)
Copy the "question.txt" to your SD card, and load hamstudy.spin into the EEPROM and
you'll have study questions to go!
I'm sure I'll find ways to improve this as I go along, but here's a working version of 1.0

A. Yell as loudly as you can into the microphone
No questions regarding Number Stations?

And I also thought for sure they were going to have the trick Marconi / Tesla question ;-)
Nice job on the program.

"What instrument would you use to measure reflected power?
Had that been on the exam I took, I would have picked that answer ... just because.

I thought that the answer to that was: "Mr. Watson, come here, I need you!" said with a "spilled acid" tone.
No, wait! that is an emergency telephone call. Sorry
I just had a terrible idea - how about a 'morse code keyboard'? key in what you want in morse code and the prop translates it into PS/2 so you can type on your computer in morse code.

What a neat idea.. I could incorporate that using the single pushbutton on the PropModule.

Seems like it would be pretty easy to use any prop board w/kbd and audio.
An interesting, but not too difficult,·challenge would be to go the other way 'round: Morse audio in, text display out - all with the prop.
eh?

Looking up I see some text scrolling across screen in a red banner. I start to get nervous. Jees, has the thrid world war started? Looking closer I see the text in the banner is announcing the a bear has walked into the city of Lappeenranta, and it is warning residents to stay indoors! (The banner that is not the bear[noparse]:)[/noparse]
Quite why they were panicking me about this I don't know I'm 150Km away in Helsinki.
Some days later I get disturbed by some more another red banner and some more Morse code. This time it's "CQ" and the banner announces it's only a test message.
Some more days pass and there comes another "SOS" in Morse from the TV. Guess what. Another bear has attacked some one in Lappeenranta.
I was quite heartened to hear that Morse is still in use but did wonder how many people watching national TV now a days would recognize it. My wife was impressed that I did (It's the only Morse I know, but we won't tell here that).
Epilogue: Whenever a bear turns up in a populated area in Finland it always ends up getting shot which I think is all wrong as we are living on the edge of a wilderness and should accommodate what is out there.
How do they deal with this in, say, Canada?

When I was training for my pilot's license, the single biggest factor contributing to my quitting (other than how fazooking expensive it is) was that I could barely understand the radio. I have always wondered if getting more comfortable on the radio while not doing something else like trying to learn to fly a plane would help things, if it was just that I can't multitask very well, or my brain does not process signals very well.
On the other hand, I have no clue what I would talk about on a ham radio, maybe they're all talking about the prop chip and we don't know it. I guess tests are cheap.
wonder if that's true even years after getting a license ?
I mean, why else do you think they call it "HAM" radio ? :-P
... seriously though, as tropical storms and hurricanes begin to bear down on us here in the southern US, emergency communications start to look pretty important.

One thing that you need to consider and compensate for, is that everyone has a different hand - i.e. their keying speed, or the length of time for a dot or a dash, is different - in fact, even one specific person will have slightly different hand for each letter, that is one of the things that let's you tell whether you are listening to a real person or a machine. Every single bit of tone would need to be compared to the length of tone just before it (and maybe the tone after it) to determine whether it is a dot or dash. Actually, the spaces between dots and dashes would need to be compared to the tones and blanks before and after to determine intercharacter or interword breaks.
I have not actually written anything other than some practice programs for learning code, but I have read up on translating code to written characters.
