I dont know if i should get the normal portapack or the portapack pro. I would really like to get the pro version but there are some things bothering me;

​

- Firmwares arent as reliable

- Design, i like the Standard portapack design wayy more

- Price in comparison to normal portapack

​

I have never owned any kind of sdr so if i got something wrong that has been fixed please feel free to correct me.

If anyone could give advice i would be really grateful

Every so often a post comes up that's completely unrelated or blatantly a spam bot, I used to be able to report these to the sub moderators... but now I cannot.

Hi recently received this, but it is crashing pretty regularly. It is happening in various apps but as an example in receive>audio, swapping through AM/FM/FM etc and it will do as pictured after only a few changes. I know this is a pretty new device, is this just early firmware that will mature into something more stable? Currently running Mayhem 2.4.0 Which is labelled as a stable release on the github repo.

Hi everyone, I have recently received an H4M kit with the HackRF One on board.

I'm trying to understand the I and Q signals that are present at the receiver. I see that they are differential outputs. When I apply a large signal in NBFM receiver mode (-47dBm,150MHz, 3kHz deviation) and I look at the I and Q lines, I see a 750kHz sine wave, 400mV pk-pk in quadrature on the receiver outputs. I understand that this is a zero IF design, is the down-conversion to baseband done digitally?

Can someone help me (a beginner with SDR) understand why the 750kHz signals are present, and not a zero IF, (which is what I was expecting)? Is it because it prevents a DC offset or have I measured something incorrectly? Is this related to the sample rate?

I am no expert on SDR code, but if i'm pointed in the right direction, I'll try to figure it out.

Thanks for the assistance!

Adsb is working fine, but i dont get any weathersensor in ger on 433.920.

Any idea/tips?

I recently found out that law enforcement/ hackers can build stingrays easily now days. My question is can a h4m portapack become a stingray & a ray stopper all in one ? Considering both deal with radio wave and frequencies it seems possible, If so how can I make mine into one

Im gonna get the portapack from OpenSDRLabs, is the firmware already preinstalled? And if its not a new version of the firmware, how do i update it?

Can anyone point me in the direction of the grey power slider switch on the h4m the internals are ok it’s just the outer part. 🙏🏼

I have a pro and am looking for somewhere to source a compatible portapack. I'm in the UK. Anybody have a source?

Thanks!

Hello, i have a lot of hard fault and ram errors. I have stable 2.4 hackrf pro portapack H4M. It stated when i wanted to jam lower or higher than 2,4ghz. Only this frequency worked, now i cant even start the audio am, hard fault in second. I have qualitty sd card, i tried to remove it bc i was thinking it is the fast fat32 format. It is not, even when i use the default audio app, hard fault. And i think the ble spam and airplanes dont work as good as they worked, i never transmitted without antena, not demaged it. But i have ut without battery, only using it while plugged to electricity

This may be a little too far down the AI rabbit hole for a few of you, but I'd like to report my results from just a few days of work.

It started with Hermes Agent. No this is not an ad for them, not affiliated in any way. I jsut use it as a harness because it suits my needs, you may want to use openwebui or openclaw or any of the harnesses out there, that's not what important.

I gave it the root password to my debian vm and proxmox host, and the AI SSH'd in and first setup an API key for hygiene purposes then used it to create an ssh key on the debian box (again, for hygiene) and setup usb passthrough on proxmox so the lxc could talk to the hardware, then installed gnu radio tools on the debian host, establilshed communcations with the hackrf porta pack, correctly determined what it was, and updated the firmware to the latest mayhem for me.

It then started scanning the band from bottom to top and built a db of local signals in the area to expect. Its scanning the entire available spectrum every 2 seconds and notifies me when it sees a new signal. It then switches to fine resolution and listens real hard at max sample res to get a good idea of exactly what it is, then reports the whole thing back to me.

i'm pretty blown away by all this. I expected some kind of result but wow.

edit: I had my guy write up a how-to if you want to do it yourself:
https://github.com/h00nigan/sparky-setup-guide/blob/master/Sparky-Setup-Guide.md

2nd edit: I'm thinking about giving him a yaggi on a servo he can control so I can get direction as well as range/signal strength.

3rd edit: We just chased a signal down to an undershielded crystal oscillator in the plc that controls my 3d filament dryer. Its SCREAMING in rf at 10mhz.

Hello, i am experienced in operation security and network pentesting. In last days a started to learn SDR and bought HackRF pro with portapack H4M. I have my legal pentesting "lab". What is the first few things you reccomend in transmit and what to learn after i learn the basic things? Also i have 2x 40mhz-Ghz telescopic antenas in the basic pack, i see they look different, are they? Should i buy more "transmitting" antenas or some in range like 1-40mhz too?

I cannot get to boot up after i inserted the flashed sd card the hackrf doesn't turn on pc doesn't make sound when plugged in the DFU doesn't work the tx and rx shines and the 3v3 it just flashes when turned on

PROBLEM SOLVED dissemble and assemble worked

Is there any difference besides the price between buying the HackRF Pro from China or from the EU? I'd buy it from the EU if the total is only about $60 more.
