Dont know exactly, i just want to play around a little bit.
Maybe locating a weather station transmitter or something like that.
Or wifi signals...
So mainly 433 MHz and 2,4 Ghz.
The only logper antenna which goes down to 400 MHz i found is quite large, understandably :)

Guess i will stick to my telescopic antenna.

I ordered a HackRF too...  it will take a while until its here.
Meanwhile i watched a lot of videos and in one of the videos someone showed how to receive and decode the signals from a weather station sensor on 433 MHz.
It was on a HackRF with Portapack and it was done via the device itself.
Unfortunately i cant find the video again, so i looked at the firmware features and it looks for me that it is not possible to receive and decode those weather station signals without using a computer and specific software.
Does anyone know if it is possible to do this with a standalone HackRF + Portapack ?
And if, how ?

No, as a PC is used in the video.
I saw someone using only the HackRF plus Portapack to read and also send those Weather Sensor packets.
