Ukrainian EW expert Serhii “Flash” Bestkrestnov has published a guide to the military use of the TinySA frequency analyzer.
He also provides firmware to make the device with its many settings more accessible.
Below are some of the valuable capabilities of this device.
1/ Image
“The state of the air” can be monitored to determine UHF radio communication frequencies to avoid.
2/ Image
Determining the local level of EW jamming of satellite navigation frequencies for GPS or GLONASS.
Note how these systems use a number of frequency channels.
3/ Image
The presence and intensity of local EW jamming (including friendly jammers) on the control frequency of the FPV you are about to launch.
4/ Image
Detecting the presence of Russian fixed wing reconnaissance UAVs by their distinctive telemetry signals.
With directional antennas, multiple devices this can triangulate their position to cue a Ukrainian fighter FPV.
5/ Image
Detecting the presence and distance (by signal strength) of nearby Russian fixed-wing kamikazes such as the formidable Lancet.
Its distinctive telemetry signal pattern is “double-horned”.
6/ Image
And crucially, detecting the video transmission signals of nearby Russian Mavics and especially FPVs.
This is the fundamental function of a frontline drone detector.

Russian blogger Ilya Mersh (“Older than the Edda”) argues that the drone revolution will force the use of very expensive heavily armored APCs and tanks with multiple anti-FPV systems.

“The era of drones, which has currently completely changed the face of war, …
1/ Image
“…will very soon lead to the revival of heavy armored vehicles. Tanks and heavy APCs/IFVs are what will be able, if not to completely neutralize the drone threat, then at least to ensure breakthroughs and the delivery of soldiers, ammunition, and supplies to the front line.
2/
“Makeshift delivery vehicles in the form of motorcycles and cars modified in the style of Mad Max will become a thing of the past, remaining only with weak and semi-partisan armies, …

Russian blogger “Two Majors” accuses Chinese cars of being “mobile reconnaissance platforms” often with built-in drone stations that are increasingly being banned from entering or even parking near strategic facilities.

“🇨🇳🇷🇺Civil car or drone reconnaissance platform: …
1/
“…are security measures lagging behind technological development?

Videos and articles about the rapid development of Chinese automotive technology are increasingly common on the internet.
2/
“The automotive giants of the Middle Kingdom actively cooperate with leaders in other fields, such as the company DJI, which is a leader in the drone market. The result of such cooperation is an increasing number of civilian cars with built-in drone stations.

A Ukrainian primer explains how Russia gathers information from cell phone use in the grey zone and its consequences.

“Why you need to be careful when using a phone at the front line. Let's consider the issue using the example of the ELINT system (Electronic Intelligence).
1/ Image
“ELINT usually works only on group targets. Three or more phones in one place in the forest and the artillery gets the target designation. The radio intelligence complex shows the SIM card number, the phone's serial number, and the signal strength from the phone.
2/
“The front line is not just a couple of kilometers of the frontline. Do not keep phones turned on where artillery can reach. If you urgently need to call, use only one phone at a time within a 700-meter area.

Ukrainian blogger Roman Shrike quotes verified kill ratios in Ukraine's favor of 1:12–1:18 in sectors where Russia is assaulting, and predicts Russia will begin to fail in 2026.

“Every day on my news channel I post updates of the DeepState map.
1/
“And since October 2023, with rare exceptions, every day we see losses reflecting the ongoing Russian offensive.

I understand that holding every kilometer is paid for with the sweat and blood of Ukrainian soldiers.
2/
“I understand how painful it is for people who grew up in these places to see them marked in red. I understand that any of our losses are felt deeply.

Russian blogger “Military Manager” reveals the tremendous importance of the huge Ukrainian “Baba Yaga” heavy drone fleet, while the Russian's hardly have any.

“The heavy drones of the Ukrainians started causing problems literally from the moment they appeared on the front.
1/
“Today, they have become literally ubiquitous and perform a huge amount of incredibly important and complex work for the enemy. Heavy drones have become the backbone of the enemy's FPV drone operations; without their work as relays, the effectiveness of enemy strike drones…
2/
“…of enemy strike drones would be significantly lower. The enemy regularly conducts sorties with these drones as aerial motherships for strikes on our rear areas. They also supply the enemy's cut-off soldiers.

Serhii “Flash” Beskrestnov has witnessed the vast scale of the comprehensive operations of the Ukrainian SBU to track and document every Russian crime and atrocity.

“No one will go unpunished.
1/ Image
“In our country, there are many structures and agencies that perform important work, but few people talk about it.

Did you know that all crimes committed by Russians against the Ukrainian people are documented and recorded?
2/ Image
“And this is done very thoroughly because every war crime has a name.

This is handled by the Main Investigative Department of the SBU.
Where do I intersect with them? Of course, in the field of trophies. Missiles, Shaheds, other UAVs.
