HackRF One

Recently picked up a HackRF One. I have a few rtl-sdr dongles which seemed okay but I wanted to experiment with some RX and TX with the hackrf. I've used it with SDR# and gqrx. Normally with any sdr I setup and tune to the local weather station. With the hackrf I can't seem to RX something even close to clear.

I've swapped out known good antenna and usb cable. I've tinkered with the gain and setting within the software to attempt to boost the signal but it really raises the noise as well. I've come across a few mentions of the poor RX of the hackrf. This was after I had it sitting in my living room paid for mind you.

FM radio comes in but seems significantly weaker. I'm curious as to what others have experienced and if they have identified settings that work better. The performance seems bad enough to wonder if it's a dud.

Comment on The Open Source OVI-40 SDR Transceiver by Arthur Ripple

on the pre order web page there are many options available but I can not see enough info to decide what to order no links to description of each item ?
I ordered a OVI-40 UI and a large display soldered partially, but not so sure I ordered the biggest one ?
and all parts needed to get it running?

Is Astra 1f, the same as Astra 1L 1N?

I am not sure if I am asking the right subreddit but I try to connect to Astra 1L 1N but the receiver only shows me Astra 1f-1l satelite. Their angles are the same (19.2E). But I couldnt quite work it out. Please, someone help.

P.S. There are no problems in the satelite, I have watched Astra on it before but it was like 5 years ago.

We have just had our Thames Water (London UK) smart meter installed. After a few hours of searching I think I have found some info. Does anyone know if it transmits on 433 or 868 Mhz. It seems to transmit to another unit just under the cover which according to the installer is the unit that transmits it out to the world. That says FlexNet550M ESAAP Smart Point.

How do I get to see the info about what actually is for sale a description of each item on the pre order list what is included in each item for sale there?

Comment on Noise Cancellation using Linrad and the Phase Coherent Capabilities of an RSPduo by Ian Bennett

Why not record the interference (repetitive man-made coherent noise e.g. 50/60Hz switching noise) and play it back subtracting it from the signal during a qso using software algorithm and adjusting phase/timing manually or automatically to remove 50/60hz components???

Trying to activate bias t through raspberry pi to run spyserver with upconverter but it gives me an error :(

Hi, I successfully set up a spyserver and now I want it to work with the spyverter that I just bought. I can't activate rtl_biast with the comand rtl_biast -b 1. It gives me this error rtl_biast: symbol lookup error. rtl_biast: undefined symbol: rtlsdr_set_bias_tee

So obviously if I run the spyserver it doesn't work because the upconverter is not on. It does work if I unplug the upconverter and I can hear vhf/uhf no problems what so ever though.

I'm pretty new to raspberry pi and linux overall, and I have installed stuff and I don't know exactly what I've done... If somebody could give me basic guidelines on how to make the bias t work or check if it's installed correctly I would greatly appreciate it.

I know this is somewhat more appropriate for a linux help subreddit but since this is probably something a lot of people here have done I figured out it would be better to ask over here. I just read too many tutorials and done too many things and I can't get it working. Would have been great to note down everything that I tried but I didn't so yeah... Help me plase. Thanks

Other SDR Devices • Re: RSP1A with SDR# v1668

That is Yousef's intent..
I have all the Airspy stuff except the HF+ but I have no use for SDR#, just SpectrumSpy.
Otherwise I use HDSDR and SDR-Console or SDRUno.. I do have an RSP1 and RSP2
