Well, not the dead ones, of course, if that was the "spirit" of your argument (uggh - bad pun, sorry).

But as for the living ones, yes, they do have SOME access and ability to use ham (not an acronym so no need to capitalize it) radio gear and frequencies, if they think it will help. Ham radio is also known as amateur radio.

Baofeng, or similar Cheap Chinese Radios (CCR's) sell for less than $30.00 on Amazon or eBay. You can't believe that none of the protesters have relatives or friends in other countries that could BUY the gear for them? Their main problem is they are short range and will likely require a similar radio at the other end to receive them.

For longer range communications, there are a lot of different QRP, or low power - less than 5 Watts - type of "HF" transceivers that can go much longer distances but require larger and longer antennas than walkie-talkie type radios. These are a little more expensive, usually around $100.00 or so and higher, all the way through several thousand dollars for really high-end digital (SDR) all-band, all-mode "HF" transceivers.

Also, recently there has been an emergence of "mesh network" type devices. Those are usually UHF/VHF, so a local radio IP-network type of service is established by a small fleet of walkie-talkie like devices operating in a peer-to-peer fashion as "hotspots" or portable access points, all nodes in the mesh. These are not necessarily operating on amateur radio specific frequencies, but could be.

So, the protesters should have some potential to use various amateur radio services or equipment, depending on their ability to buy or smuggle in radios that were either bought for them by confederates or family members, etc. or to access ones that were available to them prior to the crackdown.

"Cow Corn", or Field Corn, as it's properly known, mostly goes to produce a large amount of a little product you might have heard of - automotive fuel - Ethanol, or "GASOHOL" as it's sometimes called.

Plus, it's still used to feed cows as noted, so land to grow Field Corn is not a waste by any means, it's use is more important than ever.

"Cow Corn" - it's not just for dinner anymore! (moo)

The only remotely interesting thing was about Apple making them change the computer since it became evil. I had heard before that they are militant in movie productions about not letting the "Bad Guys (TM)" have an iPhone!

I thought about that and it came to me that it was a huge spoiler for a suspense movie, a double agent having an Android would be a dead giveaway!

It was caused by laser rot, or Laser Diode degradation. The early players had lasers in them running as hard and hot as they could make them at the time, and over time the power output would decrease and the players would start skipping, or only work on their side, and it would get worse over time.

I had 3 of the Sony D-5 original "Discman" players and they all did the same thing, they lasted with daily use for about a year or so then started to exhibit the problems. This was only a problem for the first few years of CDs, by the time re-writable CD's came out, the the lasers were capable of much higher power and would last much longer at the lower power (playback mode) settings.

Some "QRP" or low power experimenters as you state play with very low power (under 5W), but most of the 900 MHz activity is simple analog or digital repeaters, like APCO/P25. If they are using standard LMR (2 way radio, like public safety) repeaters, they are using power levels from 35 to 300W TX Power typically. The antenna gains used give them 1x to 10x gain (from unity to ~10dB), so that gives typical total ERP values of 35 to 3000W.

Most amateurs using this band do not use full legal power there, unless they are playing with EME (Earth-Moon-Earth) stations or other specialized point to point applications.

Also, 900 MHz ham operations are not that common, in my state they are almost exclusively only in large metro city areas, and for example there are 500 repeaters total on all the various ham bands, and of them there are only maybe 25 total 900 MHz systems, state wide. Most systems are on the 2 meter or 70 cm (440 MHz) bands, with 220 MHz as the next most popular band.

Note that there are protected "weak signal" areas of the band reserved for those "QRP" or ultra low-power operators and for things like satellite signal earth station works. There are distinct "preserves" or areas of the band that are designated for that low power use only and repeaters or any other signals exceeding 1 or 5 W max are very much prohibited in these parts of the band.

They are burning tires or other garbage in a cooling tower, from what I have gathered. They are pretty far from the main containment facility, especially the reactors, which I believe are in shutdown now. If so, the cooling towers aren't being used if the plant is in a standby state.

There's not much inside a cooling tower to damage or catch fire. If you've ever seen pictures inside one, or seen the movie Brazil, it's just a network of radial steam pipes that make up a "floor", with holes in them to let the steam out. The platform of pipes is raised about 20-30 feet from the actual ground below. Nothing particularly flammable about it.

Other than maybe a few small valves, pumps or other actuator type control equipment, there is not much that's either electronic or particularly sensitive inside them. The walls are reinforced concrete, AFAIK, and they also are not flammable.

Although Putin might be embarrassed, he won't deliberately risk an accident there. It would cause too much blowback and they would be risking nuking themselves, essentially. But, there is always the possibility of an accidental shooting or explosion that can happen, and neither side wants that.

Building a tire fire inside a cooling tower is either because the troops there are bored, or it might be their way of trying to act threatening - but anyone with a little knowledge of how the plants work will not be easily fooled.
