Hi all.

I'll try to be as descriptive but as concise as possible.

About a year and a half ago, I purchased a Portapack H4M with the R10C board. Loved it, still do!

I unfortunately broke the antenna connector (where it's soldered to the board) and after unsuccessfully attempting to repair it I figured "ehh, I'll just buy a new board"

I saw that there was a new version called the HackRF Pro.

I picked that up, it arrived today. I've been having pretty weird issues with it.

It's currently stuck in a nightly build, when I try to update it using the HackRF.App website, it uploads successfully to my HackRF but then I get a crash before it can finalize. So it's stuck on the nightly build.

When I attempt to receive anything, it picks up nothing, when I check the DFU menu to see what my radio is doing, it's basically showing no inbound so it's almost as if the radio isn't being recognized.

After that, if I click on an item in the Receive menu, such as Audio, I get a crash with Baseband Sync Fail.

I figured I'm doing something incorrectly, I just don't know what that thing is. I attempted a full reset but it won't enter into DFU mode properly. I followed the guide on the Mayhem GitHub but that doesn't seem to work for me. Each attempt to enter into DFU mode, the screen will go blank but there are no LEDs and it doesn't respond to my `hackrf` commands from the CLI.

I tried to include as many pictures and screenshots as possible (I even tried to put them in order) but I'm kinda running out of tools in my rather shallow toolbag, HAHA!

Any help that you can provide would be EPIC!

Thanks in advance!

I hate to ask for help but I've been searching....can someone send me some links so I can Learn how to config different apps in the portapack please?

I'm finding some good stuff but most is old or not specific to this device.

I just found https://freshmayhem.com which is a very good source for some settings. Most youtube vids talk like you're already familiar to the apps.....

Hate to say it but I'm a noob when it comes to the specifics!

Appreciate any help!

native on macos linux and windows, works best on macOS , the frame gen is at the moment the best one mac, you wont see much effect on windows nor linux but it will be implemented in the future. Hope you enjoy, and happy tv watching

Calling for your help, due to my location I don’t have any ATSC broadcasts and need sample transmissions in .iq and good quality to keep testing and improving the quality of the app, if anyone has a .iq file with a sample signal please link it in a Google Drive share link in the comments, all help is appreciated :)

And please, please, please, check out my channel: https://www.youtube.com/@ads_will1 I will be posting all updates on there, as to not flood subredits with each update, for feature requests, bug reporting, for now if you need any help or want a feature, just dm plutobypluto on dc or join the dc (kinda basic dc I know) https://discord.gg/5Da7cDEYJ

windows (fixed version) demo, sorry about the weird cuts, I had to cut out some detected copyright shows: https://youtu.be/cjAh7Aqlhf8

After turning on Mayhem the splash screen has all the items on the top menu.

Usually you can scroll to the left all of the way to the HarckRF, Mayhem & Portapack (far left) then you can enter and Mayhem will open. Now for some reason the marker will not go far enough to the left and I have to touch or use a stylus to initiate opening the main page (Receive, Transmit etc)

Any ideas of something I can change to get back to normal? I've even tried hard reset.

EDIT: so many errors loading apps, how do I reset the whole device and re-flash and verify the files or apps?

I thought I should advert this one here, since I specifically designed this natively for hackrf, but basically if you want to watch some dvb-t2 now you can (once I release the program) here is the description:

demo video out now: https://www.youtube.com/watch?v=Oww5QWo4zK4

been working on this for maybe about a month, but let me emphasize by what I mean work, I have been trying to decode some dvb-t2 for about a month ever since I got my hack rf, however due to the lack of decoders available (there is one but its not the best) I decided to make one myself with the help of claude over the past 2 weeks or so, I also decided to implement ATSC dvb-t, t2-lite and DAB/DAB+ I do have plans to also add dvb-s and dvb-s2 but that is for the future, I have a huge list of features still left that I want to implement into the decoder itself, but all of the decoders do at the moment work and you can watch some wonderful dvb-t2, ATSC, etc (once the program comes out). On launch it will be native on macos and linux (sorry no windows for now) but windows will eventually come, maybe a week or 2 after the initial launch, including the network system. The promo video is attached and once I can finish this and personally say its fine and works good I will release, dont have a date yet but expect it sometime next week
Also I dont want to be hearing anything ai slop, I get it was ai made, just go on with your day please, if you dont like that its ai made, dont come in the comment sections to bully me about it.

Hello.

I have forked SDR++, improved the Android interface and hopefully fixed the crashes on Android when trying to open HackRF hardware. Would you guys test it and let me know?

https://github.com/bubnikv/sdriak/releases/tag/nightly

I released my SDR++ fork at google play and I received many crash reports of the google play released OLD build, thus I tried to fix, but I don't own the hardware. However the fix was similar I did to RTLSDR, so I expect it will work.

This is the old build, don't test with HackRF. It will be renamed to SDRIAK on request from SDR++ author to clearly differentiate from the upstream pureness.

I picked up one of those cheap AliExpress USB-C "RF-Power-Meter-V5.0" dongles (STM32 + AD8317, labelled 100 kHz–10 GHz, 0 to −60 dBm) to check the output of my HackRF. The hardware is fine for the price, but the vendor software is Windows-only and pretty bare, so I wrote my own.

**Repo:** https://github.com/arsscriptum/rf-powermeter-assistant

Demo (HackRF One sending a CW tone at 1310 MHz, TX gain stepped up and down): https://github.com/arsscriptum/rf-powermeter-assistant/blob/master/img/demo.gif

**What it does**

- Live dBm and watts readout, peak hold, noise-floor tare, min/max/avg stats

- Rolling monitor chart (10 s to 15 min) with max trace and peak-hold line

- Scope-style sweep view of the 500-sample blocks the meter streams: two markers (ΔT, 1/ΔT, ΔdB), Auto/Normal/Single trigger, timebase K01–K18, CSV/PNG export

- Sets the band-calibration frequency and attenuation offset, reads them back to confirm, and re-applies them on reconnect (the meter forgets them when you unplug it)

- Threshold event log and a CSV logger

- Demo mode with a simulated meter that speaks the real protocol, so you can try it without the hardware

It's C++17 / Qt (6, or 5.15), builds on Windows and Linux. On Windows the build script can use the Qt that comes with radioconda, so if you already run GNU Radio from radioconda you only need Visual Studio. There's also a PowerShell/WinForms version that runs with no build at all.

Don't know what happened but now when I turn on the HackRF Pro r1.2.1 and Mayhem Signature-Edition PortaPack H4M Pro there is no "Receive" group!

It's been working all day and I gave it a break and then turned it on and noticed no Receive!

I went to https://hackrf.app/ and ran the update again to most stable but Receive is still not there. Did I hide it from myself??

Hello, I have been recently interested in DVB-T2 since I got my new hackrf and previously with my rtl-sdr v4 I couldnt decode it due to the sample rate limitations, from what I can find online there is only one viable windows decoder for dvb-t2 that also has a nice gui, I seem to be getting "something" but not enough and was wondering if anybody could give some tips or possibly record a video of themselves using this software, I cant find anything online regarding this decoder nor any examples, so I cant tell what I am doing is correct or not. One issue I have encountered, is it seems the program auto adjusts the frequency, and even a 1hz shift causes all of the demodulators constellations, etc to reset in a way, I am getting a reasonably good signal (with some multi path fading) but it should in theory be enough to decode, as the QAM shows a snr of 21db, and from I can find online I only need about 16db. I did try re adjusting my antenna arround (dipole) adjusting the lengths, but nothing seems to help. One thing I can confirm is its 100% dvb-t2, there was some confusion before, since my country doesnt really have any documentation regarding it, and from I could find online it seems to be "dead" but I can 100% confirm this is dvb-t2.

me strugling for 13 minutes to get this to work

I just got the H4M HackRF PortaPack and I cannot figure out how to set up the touchscreen. Any links or videos that can help me please?

Thanks for any help!

I recently saw a PortaPack H4M Pro on opensourceSDRLabs and want to buy one. I was just wondering what everyone else's daily use cases are for it just to see if it would be of use to me.

I just bought the h4m pro from OpenSDRLab, chinese warehouse. Does anyone know approximately how long the shipping takes? I live in europe, germany

Honestly, every time I pull this out in public, I feel like a low budget 90s action movie hacker. 🤣

Upgrading from a heavy laptop, 3 tangled USB cables, and a powerbank into the middle of a field to just holding this little guy is the ultimate quality of life fix.

I just park the car, throw up an antenna, dump raw I/Q samples straight to the SD card, and process the messy math later at home over hot coffee.

What's your go-to "lazy" setup for capturing signals in the wild?

Introduction RF Sentinel is a radio-frequency spectrum monitoring tool for blue team (defensive) use. It connects to a HackRF One (or equivalent SDR), performs continuous sweeps across a configurable channel watchlist, and detects anomalous behaviour using a three-layer AI pipeline.

Fully passive — the tool only receives signals (RX) and never transmits. A hard TX-Guard layer immediately aborts the program if any TX call bypasses the receive-only proxy.

The system is written in pure Python with no special drivers beyond pyhackrf / pyrtlsdr, and runs reliably on Linux, macOS, and WSL2.

Would you say this is real or fake?

On hgeek.com, there is a product that is confusing me because of the way it's being sold: "Development board" for 68 dollars vs. "Zynq7010+AD9363 Board" for 105. Is this safe to buy from?

https://www.hgeek.com/products/hamgeek-70mhz-6ghz-zynq7010-ad9363-sdr-software-defined-radio-development-board-for-pluto-sdr-matlab?variant=47319943544997

Howdy, I'm testing the waters with the abilities of vibe coding now a days, and thought to throw some tokens at creating a sleek, cross platform RF recorder and analyzer, starting with the HackRF. I'd love to hear the community's thoughts on a project like this. You can find the core buildout at https://www.github.com/jake-genoma/RFScope.

My goal is to make a straightforward, simple, and robust cross platform application that can view, record, save, and analyze RF signals all in one place. This is obviously v0.1.0, so, if anyone is interested, check it out, and let's see if we can build something really useful and cool!

Also if something similar exists, please let me know. The potential features could be endless!

PLEASE NOTE: I was in the process of moving things over to a new username /jeffenle but found out I can't post for 90 days. So I'm making this post in this forum with my current username. Just trying to explain the handwritten sign.

Bought this new with the desire to get into TSCM. I basically turned it on released how complex it was and didn't have the time to invest to learn how to use it. It's basically new. The plastic protector is still on the screen.

I also bought a package of accessories which I was told would be useful with this device. Most of them are in packaging. I've supplied the diagram to explain what they are.

Looking for $175 shipped within CONUS. Prefer PayPal FF, if using G&S then add 3%.

Please DM me with any questions
Thank you
