Imo your speculation would benefit from some numbers: just how much the price difference would be between standard transception hardware and the sort that is hardened against eavesdropping, jamming and frying. Talk about which readily-available components go into the upgrade at both ends.
That would be a useful antidote to the vagueness of saying it could be “done pretty cheaply”.
I’m not sure about this, but I remember overhearing someone with the right Ph. D. saying that hardened electronics are a controlled commodity and only available to contractors with the suitable clearances.

State Duma deputy Kartapolov: Russia creates conditions for launching a counteroffensive
Russia has launched the process of creating conditions for launching an offensive in the zone of a special military operation. This URA.RU said the head of the State Duma Defense Committee Andrey Kartapolov.
“As for the offensive, it is necessary to create conditions. This process is underway,” Andrey Kartapolov said.
Earlier, Newsweek, citing a source close to the Ukrainian government, said that Russia was preparing its offensive in Ukraine. According to him, preparations will begin in October, and in the spring of 2024 a powerful blow will be delivered to the positions of the Ukrainian armed forces.

And for what
So they will advance, then retreat, until the population is reduced.
Maybe it's time for this general to command on the front lines.
For generals up to 70 years old now, but he is not yet 60 ..
start preparing a counteroffensive, not through the territory of Donbass, but through the Belgorod, Kursk, Bryansk regions, through Belarus, in order to hit the rear of the army of the Armed Forces of Ukraine. And capture Kharkov as a result of this counteroffensive. Sumy, Chernihiv. And after that, the entire defense of the enemy can crumble. since the All-Union Force will be forced to withdraw its units from the Donbass in order to try to stop the counteroffensive in the northeast. Ukraine.
So the goals will not be achieved.
Have you already set specific goals?
Mobilization in autumn?

See if this works, "X" wants me to log in. maybe others will have more luck.
And this poster was not shaddow-banned (yet) by Mr. X.

You can harden any electronics with a Faraday cage and higher-grade components bought from digikey are more expensive than those from China. These things don't need to be EMP proof, just more resistant to jamming and EMP weapons and able to operate over more of the radio spectrum than hobbyists. It's like the commercial GPS drones use, it's not fast enough for a missile, but works fine with a drone.

Much hard data is secret, this is war after all, but as a point of reference, Moscow was GPS jammed to death and autonomous drones could not operate there. Recently however the Ukrainians appear to have overcome this and now can accurately target points in the city as we have seen on the news. There are several methods by which they could have done this and at this point we don't know how they are doing it, but they are doing it.

If the Russians have been using these to blunt the Ukrainian offensive, they have been paying for it. I wonder how many of the remaining are serviceable at any given time. Lobbing unguided missiles in clusters from a few miles out can't be very accurate and I doubt the results are worth the risk.

I’m not an EE (and I did not stay at a Holiday Inn Express) but I’m guessing that it is easier to work around jamming than EMP.
A simple but “accuracy is expensive” option is internal (inertial) guidance.
The demand on an inertial reference stage can be lowered by using optical waypoint recognition or perhaps a secure datalink outside the jammed band, handing off to internal if/when the link is broken.
EMP has a figurative plus and a minus. The plus is that generating a large pulse without a nuke is difficult.
The minus is that you either need hardened electronics, or you forgo semiconductors in your device.
Are tube circuits hard relative to ICs?

With Trump locked up and muzzled, his minions, cronies and allies will be laying low, on the run or indicted, so the Ukraine supporting faction could make some gains. Ukraine is one of the main issues dividing the GOP.

A faraday cage and pray, for lower powered directed EMP weapons, reducing their effective range would be useful. As for better drone comms, collapse the video and control into a single data stream that can be encrypted, and frequency shifted over much more of the radio spectrum. Suicide quad drones don't use GPS so jamming it is not an issue for them.
The general idea here is to cheaply adapt dual use technology that is cheap, widely available and adaptable and RC electronics fit the bill, from the control radios with JR module bays, to the several protocols the receivers can use to talk to the $100 flight control computer. Solutions for commercial DJI drones might differ or they can roll their own such drones using parts from the global marketplace and their own custom software. It is the combination of the cheap technology, global marketplace and a hobbyist/engineer community that puts it all together. A lot of this started with smartphones that contain many of the cheap mass-produced basic components like small cameras, magnetometers, accelerometers and such.

Tubes are mostly immune.
A faraday cage would be wonderful if you did not have to engage with the outside world. The problem with developing custom software is that it takes time, the more sophisticated the requirement the more time. In that time the Russians are also working to combat Ukranian advances. The Russians are no stranger to jamming and they did have a robust IT industry.

Constant innovation and adaptation are the hallmarks of war on technology, I kinda look at it like WW1 when planes were first used in combat. These things are just too damn useful on the battlefield not to put the effort into developing them. The Ukrainians were losing a lot of drones, but recently they are not losing nearly as many DJI types of drones, the battlefield FPV drones are not as subject to such jamming or EMP weapons, they fly low and fast. Likewise, GPS jamming over Moscow was an issue, but not lately it seems. Ukraine has a lot of help in this low-cost cheap drone realm from the global hobbyist and engineering community along with their own people.
I knew off the top of my head how much an FPV drone should cost when bought in bulk, around $400 USD and while not as good as a Javelin, it is a lot cheaper and has a longer reach. I didn't think they would be as effective as they are on tanks though. The main thing is they can be vastly improved mostly with the comms system, it is easy to jam the narrow bandwidth they all use by law and in Ukraine they make the law.

Over time things will develop. Your posts sometimes seem like a quick wave of the hand will deliver Ukraine the goods. But having been in the electronic industry and knowing people that developed products I have a different view as to what is possible. Like the idea of using waypoints for the drones rather than GPS. The problem is you need a good map of the territory to use to tell the drone where to go. The electronics need to detect the landmarks and determine what they are looking at. A tall order for a consumer drone at this stage. One of the reasons the US was real concerned by the Russians capturing one of their advanced drones. The hardware was one thing, the software the real prize. From what I understand they sent a command to destroy the code. I think we will see the capability in 2-5 years, maybe even swarms of drones with a shared intelligence.

It is much easier to implement these technologies today with off the shelf parts and even chunks of code found on discord servers. That's for adapted dual use commercial technology, as for the military the Ukrainians are getting a good sampling from many different sources of what is available. The number of drone companies and volunteer organizations has increased dramatically in Ukraine this past year. They, like other parts of the armed forces are preparing for a big push, now underway and word has it they have accumulated a lot of drones to do it. If they can overcome EW commercial drones offer the most economical and effective way to deal with the enemy at medium range. Having a good weapon is one thing, getting them fast in large quantities is another and that is where the global marketplace for components and parts comes into play, the rest is just money.

Now they have penetrated far enough, perhaps they will roll up the flanks of the Russian front, make them redeploy and then drive straight ahead to the sea of Azov by-passing built-up areas for the most part. They already made them redeploy with moves across the Dnieper near Crimea.
