I absolutely agree re: the antenna comment. Gain via aluminum beats gain via electrons every time, mostly 'cause it works on xmit and recv. I've just moved and am considering a crankup tower - I used to have a 125' fixed one, and never got around to making antenna changes/adjustments - getting all set to safely climb that high is a major ordeal, not to mention tiring and dangerous. With a crankup/foldover, I can fiddle all I want, plus the neighbors (who are mostly family) won't see the tower unless I'm operating.
The other oft-forgotten part of the equation is feedline - RG-58 isn't going to cut it on 10m/6m. Those nasty dB of loss can be overcome by raw power on transmit, but add directly to the noise on receive. Unless you want to put an preamp on the tower, good coax is necessary.
I once did the calcs on my old station - to run 432 MHz at the top of the tower, I'd be using about 300' of coax - even with top-of-the-line LMR-xxxx and an amp/preamp at the base of the tower I was still looking at less than 25% of my signal making it to the antenna. In fact, it was just enough to excite that 300 W mast mount amp I was coveting. Then I had to deal with getting power up there, etc. Ugh!
Good luck keeping the magic smoke inside that Alpha 374!
The other poster is right - the broadcasters make it difficult and the QSOs seem to be piled on top of each other. I don't have a directional antenna for the low bands, so I hear it all at once. Strangely, my LotW count for 40m DXCC is tied for third with 15m.
Agreed. Those little rubber ducky antennas are closer to dummy loads than radiators. The previous poster is right - even a modest yagi will greatly increase your signal strength to and from the ISS. I've done packet to the ISS and other sats with 5W and a PVC pipe-based quadrifilar helix.
I still do satellite observation, as do many others. I remember talking to a cosmonaut of MIR while watching him go overhead. I asked him how the sunset just was, and he wondered how I knew they'd just seen a sunset. I told him I just watched him pass into the terminator. Kinda blew his mind.
You can also use raw binary if you allow lookahead. this article has the timing info. In essence each time unit is represented by a single bit value.

Step one in your bold plan is to restrict the federal government to the things it is already specifically allowed and/or mandated to do by the constitution. All of the welfare programs are unconstitutional; I don't care if you couch them in legalese called block grants. Specific welfare is forbidden at the federal level. Commerce clause abuse? gone. I could go on for hours.
What's quasilegal? You can legally convert a CB to run Uniden HR-2510 that I talked to Russia with in my car. (That's not mine for sale, but you get the idea.)
These days an all-band mobile HF rig is not that expensive. No one says you have to put anything but a 10m antenna on it.
In case you're seriously asking, the most often used letters in the English language are mapped to the shortest symbols. E = dit, T = dah, A= dit dah, N = dah dit, I = dit dit, M = dah dah, etc.
The numbers are 1=dit dah dah dah dah, 2=dit dit dah dah dah, 3=dit dit dit dah dah,... 6=dah dit dit dit dit, 7=dah dah dit dit dit,... 9=dah dah dah dah dit, 0=dah dah dah dah dah. See the pattern?
Consider it a variable length binary encoding scheme it it helps.
My advice would be to get a used, brand-name multiband 100W transceiver (yaesu, icom, etc) with a built-in power supply instead of a single band one, and especially one from MFJ. Their reputation for quality is not exactly stellar.
As for propagation, 10m and 12m have really been booming lately, but are generally only available during daylight at your location due to F layer reflection. At night the lower bands open up. I like 80m, 20m, 17m and 15m, and I loathe 40m. But that's just my opinion.
Congrats! I know you'll have fun. HF is really hopping right now with the sunspots on the rise. I worked South Africa the other day on < 100W and a really loathsome dipole antenna only 20 feet off the ground. I made 200+ contacts last weekend in the ARRL Sweepstakes contest playing at it - I worked 68 of the 80 sections and I think 45 of the 50 states, all in 24 hours or so.
Right after that, I re-purposed the radio to listen for 6m meteor scatter.
If you're into electronics, you can easily make your own equipment. These days, with the advent of ICs for DDS and I/Q Mod/demod you can do SSB/etc with a PIC and and smile.
As opposed to participating in machine-to-machine communications where the signals are not human-readable. I appreciate the joke. FYI, I have talked to non-terrestrials - one was on MIR and the other two were on the ISS.:-)
If you limit your ham experience to talking to other humans by voice, then I can see where the internet/cell phones/etc would dull your enthusiasm.
Things get quite exciting when you include using digital modes like WSPR to exchange messages half way around the Earth with less power than a nightlight, or using very high-speed digital modes like FSK441 to exchange messages using signals _reflected off of meteor trails_, or bouncing signals _off the moon_, or using PSK31 to dig signals out of the noise that human ears can't even detect, or work stations from your living room on a handheld transceiver via an amateur-built honest-to-God satellite.
There's plenty of frontier left in the hobby - you just have to be willing to 'enhance the radio art' by experimenting and learning!

Freedom of speech does not necessarily extend to the methods used for speech.
IANAL, but I disagree. You have to separate the act from the consequences of the act.
Freedom of speech does not give you an inalienable right to stand in public area speaking my mind into a 200dB sound system.
If you don't deafen anyone (for instance, doing it in an Alaskan public park), then there's no prohibition. If you did it in Times Square, you'd likely be arrested for reckless endangerment or disturbing the peace - the act of speaking your mind isn't the issue, it's the consequences of how you did it. In other words, the content of what you said is irrelevant (you aren't arrested for the words you speak - you might as well have revved a motorcycle or something), so there's no 1st amendment issue.
Freedom of speech does not give you the right to call every number in the phone book at 2am.
Why not? Again, unless you do it repeatedly (harassment) it's not illegal, no matter if you speak your mind or just call and hang up. Again, no 1st amendment issue.
At 1:20 they explain that this helicopter started as a commercial aircraft, but later was adopted for 'special operations'.
When I saw "harpoon system" mentioned in the summary my first thought was Japanese whaling. I could see these used as automated hunter/killer craft for the Japanese "research" whaling fleet. I doubt that's the special op you're talking about.:-)

Sounds like Baudot with shift-In, shift-out, nums and figs. I don't see a lowercase-start or uppercase-start.
You don't need all the rules you defined if you have one well-defined 'escape' code, although your method might result in smaller encodings.
I'm worried about midichlorians.
That's Khaaaaaaan!!!

Yes, that was my point, and the FCC doesn't care either.

Where is the logical pattern on Morse Code?

So you're ok with banning speech that doesn't agree with your world view, then?
Society should shun those that are obnoxious and rude, but there's no place for regulating speech. AT ALL.
Freedom of speech does not necessarily extend to the methods used for speech.
