Not impossible, just extremely difficult. I'm a ham and getting some contacts over moonbounce is a personal goal of mine. Historically this kind of thing has required some pretty large antenna arrays and very high power though:
Isn't there a moon bounce mode in WSJT (or one of those digital modes) that provides enough coding gain that 100W and a single large Yagi is enough? I seem to recall hearing something like that... but, yeah, on CW a monster antenna and the legal limit of 1500W seems to be the median system.
A long time ago I started collecting parts for a 432MHz EME system. Life got in the way and I never built it out. Good luck with your endeavor!
> but, yeah, on CW a monster antenna and the legal limit of 1500W seems to be the median system.
A good ten years ago or more, they used Arecibo to transmit CW moonbounce on 70cm. I was able to receive it in my back garden with a handheld and an 11-element Yagi balanced on my clothesline ;-)
Yeah... so free space path loss at legal frequencies for hams this thing can transmit on is ~283dB. Neat idea but consider me skeptical. Having said that I can see some interesting applications for this kind of gear, EME seems overly optimistic though.
At those power levels they would have to use some kind of highly error-corrected modulation and coding scheme to provide enough coding gain to overcome the path loss. I agree they are pretty optimistic, but until they detail their modulation scheme, it's hard to tell.
A few years ago I was experimenting with 900 MHz LoRa for a work project -- we had need to communicate a very small data payload from inside elevator cabs, with forgiving latency requirements. So we took a LoRa board to a hotel building 2 city blocks away from our lab and cranked the coding gain up to the max, which gave us about a 1 byte payload every second. Perfectly sufficient for our application. Astoundingly, we had great copy in our lab even when the doors of the elevator cab were closed, inside a building 2 blocks away. I can't remember the power level, 500mW I think, but I may be wrong.
It's 1 watt per antenna. They have 240, or 53.8 dbm. So assuming 39.3 and your 283 (which seems to be around what I'm seeing online) that's -283+(39.3*2)+53.8=-150.6 dbm receive power. That should be plenty.
Yeah that is what is used for moonbounce today (if not full legal power - 1500W for US amateurs) but these little panels won't put out anything remotely close to that. Hence my skepticism.
"Bubbles are good because they leave pieces for others to pick up for free" has to be one of the most completely insane and morally bankrupt economic ideas I've ever heard. This only makes sense if you take a fully individualist, zero-sum perspective and entirely disregard all other perspectives. Nevermind the opportunity cost.
As far as I'm concerned there is no daylight between this idea and someone fighting safety measures because "trainwrecks leave free parts behind for me to pick up and build my own trains out of".
I have no moral qualms with investors losing money if it means the rest of society benefits. Sam spending billions of other people's money so that chinese researchers can make chatgpt clones for cheap is a net benefit for society.
Just follow the instructions? From your linked PDF:

Feel free to imagine that I was addressing something else. It's a free country and all.
You also might want to look at the estimated average time for a non-business taxpayer to complete a 1040. If the 1040 estimate methodology is typical, then those estimates are pretty pessimistic.
Looks like the PDF is just to show what the messaging interface looks like, and what they've found as a publicly available screenshot is from the crash report involving that plane.
If they logged in, took a screenshot, and published that (even if lots of things are blurred), there's probably more attack surface for some three-letter-agency to bust down their doors and disappear them...
Respectfully, proper technique is just a matter of searching and reading for 2-3 minutes followed by a bit of practice and repetition to get fast. You can skip the getting fast part if you want. Nobody needs "training" to become proficient with a kitchen knife.
She doesn't care. It's not possible to force someone to be a gear nerd.
She cooks, she enjoys it, she does it with a medium sharp knife that doesn't slip because that's not a real thing, and isn't scaring her because it's just medium sharp.
>Might only be available in Europe & Africa though.
Yep. We just need to move Manhattan there. Problem solved.
It's crazy how some people think there's no solution when the solution is "clear as an unmuddied lake...As clear as an azure sky of deepest summer."[0]
