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.

General Budanov was much more optimistic about 2025 in a year-end interview than he was about 2024.
However, “In the drone war, we are still winning, but the Russians have massively turned to using drones with [fiber optic] cables.
This is currently a huge problem for us…”⬇️
1/ Image
“ …because it is impossible to stop them with electronic warfare [jamming].”
“This is the know-how and trend of this year. Next year, we will all work together to find a technological solution to deal with the huge number of such devices.”
2/
“I am much more optimistic about 2025. 2025 will undoubtedly be better than this year. There are objective circumstances for this, and I hope to witness a lot of positive developments in 2025. Which will finally deliver us what we've all been waiting for.”

The Russian POM-2 is a remotely deployed fragmentation anti-personnel landmine actuated by tripwires.
It has a self-destruct and was intended for area denial in maneuver warfare.
A cascade of pyrotechnic delays and hydromechanical arming make its deployment quite interesting.
1/ Image
Image
KPOM-2 cassettes of four POM-2s are scattered by ground launchers or helicopters.
The expelling charge of the cassettes ignites the 54 s. expelling charge delay of the POM-2 canister, that holds each landmine until it reaches the ground.
2/ Image
As the mines leave the cassette, springs expel the canister cap and deploy two stabilizing streamers.
On the ground the delay completes and the expelling charge ejects the mine from the canister.
This also ignites the 2 s. fuze expelling charge delay of the landmine.

DJI Mavic drones play a crucial role in Ukraine as tactical reconnaissance assets.
Their ubiquity and high resolution cameras (including thermal) have rendered the battlefield transparent.
The Russians do upgrades to basic Mavic setups to handle harsh battlefield conditions. Image
Firmware “1001” is installed that disables ID, side lights, range and height restrictions, and GPS (so it can’t be spoofed),
“Return on Compass” allows a jammed drone to fly back until out of jamming range.
Contacts are made for a second battery, giving 50 min flight time.
2/ Image
Signal amplifiers (boosters) are added both at the controller and on the drone itself to allow operation at extended ranges, and to mitigate against jamming.
Alientech Duo 3 has a focused radiation pattern for maximum range.

There has been interest in this Russian document on Ukrainian FPV tactics, so machine translations of the interesting section on Countermeasures have been added to the post.

Russia has published a directory of Ukrainian FPV tactics with diagrams, and suggested countermeasures.
The descriptions are basic, but the 19 separate listings are a reminder of how flexible and valuable the FPV system has become.

The Russians claim they have recovered a new Ukrainian improvised anti-personnel landmine called “Gingerbread”.
When stepped on, the printed plastic casing flattens.
This drives a screw into a detonator capsule, initiating 55g of an explosive resembling C4.
1/
These devices are dropped by drones, apparently in significant numbers packed into tubes.
In comparison, the Russian PFM-1 anti-personnel landmine has 37g of explosive.
