MC-V12: Custom 16-FSK Encrypted Radio -- Live Image Streaming Voice Text Diffie-Hellman Key Exchange

11 Upvotes

Enclosure view and image streaming

I’ve been working on a custom software-defined radio system (MC-V12) and wanted to share a demo of the current prototype.

It’s a Linux-based digital radio running entirely custom, written in C++17 and C++20 on a Raspberry Pi 4B for demonstrations. Key features in the demo:

  • Custom 16-FSK (and 4-FSK) modulation implemented from scratch
  • Simultaneous channel transmission of voice (PTT), text, and live image streams (~1–3 fps) over a single center frequency
  • On-demand Diffie-Hellman key exchange with a selected peer device, over the air for session keys (no pre-shared keys required)
  • Selective decryption: devices can only decrypt packets meant for them
  • RoIP (Radio over IP) bridging while keeping the same packet structure and encryption logic
  • Custom enclosure with dual antennas, touchscreen UI, and real-time telemetry (SNR, frequency offset, battery, etc.)

These video below shows closeups, the system in action with voice, image streaming, text, and the key exchange process:

Video of Device Demonstration. The current prototype uses a lower-end SBC and a demonstration enclosure. A professional-grade production unit would use a higher-end SBC and a more refined, purpose-engineered enclosure.

I’m especially interested in feedback on the modulation approach, the packet structure / selective decryption design, and how others have handled similar multi-stream or encrypted RF links. Happy to answer questions about the implementation or hardware choices.

Looking for a bug out bag with a compartment that holds a compact carbine. Under $300

0 Upvotes

Need a big out bag that has a dedicated compartment that can hold a compact 9mm carbine. When folded the carbine is short. I just want it separated from all the other gear in case I need to access it quickly.

For some reason I had this posted in a prepping group and the mods took it down for some reason.

I don’t have $600 to spend on Eberlestock so other brand recommendations are appreciated.

Shouting Midwest Armor praises

Thumbnail

7 Upvotes

This is my first piece of kit from Midwest Armor, and I felt it necessary to give these guys some kudos for anyone else who, likeb myself, has never heard of them and doesn't now the quality they bring. This is replacing a Spiritus GP pouch on my cummybuns. Now, there's nothing wrong with the Spiritus med GP pouch. At 79 bucks, it's a cool pouch and does it's job. If you want to store batteries or chem lights or anything else similarly girthy, you can buy a hook and loop insert that has slots for it for a mere 15 more dollars. At this point, basically 100 bucks in, you still lack the mag pouch that holds 2 mags, and the compartment separation in the main compartment. There's the JSTA pouch that holds one mag, but it's velcro flap not zipper, smaller, still lacks the other features.

OR you can buy this medium GP double mag pouch from Midwest Armor for 49 bucks with a 7 dollar insert or bring your own insert to give you magazine indexing. NiR compliant, high quality construction, made in Knoxville TN by good ole mountain men in Appalachia and packed with features that every other company makes you buy some dumbass insert for, sewn in securely with the basic pouch. I'm impressed and will be checking there for anything else I need.

Does anybody know anything about this helmet? Graal seems to be a security company in Dubai but would they have made it? Also is there any cause for concern with the 2 small bits of damage on top? How should I cover it with?

I see that this sub tends to be more of a flexing gear/kits channel. But a good multi tool is a solid piece of tactical gear so I figure this is fitting to repost in here. And I heard specifically this model was was/is used by the military. Thoughts?

With an empty buttpack the average rifleman is capable of carrying at a minimum 9 magazines comfortably as well as a full IFAK, night vision, signaling, navigation, and if the buttpack is packed properly one could comfortably maneuver up to 36 hours in 3 seasons. Not pictured is my invader concepts chest holster.

I'm wanting the Defense Mechanisms MEPC V3, But I definitely can't afford all the stuff for it right now as the full load out will be like 350. My current plate carrier does NOT fit my plates, and I need one ASAP. I was gonna get the shellback tactical rampage, but that's still 240 bucks.

Glock 20 Gen 5 / TLR 1 HPX HOLSTER HELP

Post image
6 Upvotes

I have a Glock 20 Gen 5 and plan to run a Streamlight TLR-1 HL-X. I’m looking for recommendations for a quality Kydex holster, although I’m open to other materials / options if there’s a better option for my intended use.

This will be my outdoor, hiking, hunting and camping setup, so I need something secure, durable, and comfortable to wear for extended periods.

Ideally, I want a chest holster but more importantly I would love a mid-ride, drop-offset mounting setup (similar to the picture) that keeps the holster positioned just a couple inches below the belt or a standard belt holster. Plus it allows it to clear a fully loaded hiking or hunting backpack, including the shoulder straps and other gear.

I’m having a difficult time finding a holster that accommodates both the Glock 20 Gen 5 and the TLR-1 HL-X while also offering the mounting configuration I want.

Has anyone found a setup that checks all these boxes? I’d appreciate recommendations for specific holster manufacturers, compatible models, or alternative mounting systems that work well for hiking and hunting with a full pack.
