when i bought a Realistic DX-440 in the 1990s, the manual had a chart of known birdies. that radio had a first IF of 55Mhz, and a second IF of 455khz, so there wasn't a big potential for birdies, but a few did exist. i never actually tried to find them, and local noise sources probably masked them p...

i've been experiencing a minor problem with both SDRPlay -1 and -2 radios when running them on GQRX. occasionally they will start to "warble" once every 2 seconds. it looks as if the LO is being frequency modulated, and when there are signals being received (on all frequencies, meaning i can tune to...

i know this is an old thread, but if you still haven't got an answer elsewhere, you should be able to find a Pi version of multimon-ng in kali linux. https://www.offensive-security.com/kali-linux-arm-images/ if you are using Raspbian, it's possible (although i've never tried this, maybe somebody els...

i don't have this problem as much with my sdrplay, as i do with my hackrf... but, there are a couple of things you can try, first, use only the amount of gain that you need (both on the RF and the IF settings). second (and i'm not sure if this is particular to the rsp1 or on the rsp2 as well) using ...

you didn't happen to mention what operating system you are using, but it sounds like linux. xterm is a linux program that opens a command line window. xterm, or another terminal window program like it should be found in the /usr/bin folder. other similar programs will also work, but you need to set ...

DEC = decimation SR =? maybe left out a letter? SR = signal report, SNR= signal to noise ratio, SDR= software defined radio there are some acronyms that get re-used depending on what technology you are talking about: USB = upper sideband (radio), universal serial bus (computers) LSB = lower sideband...

how do i build this and specify the particular version of libusb to use? ever since i installed the latest API (2.09), i am limited to 2Mhz sample rate on both the RSP1 and RSP2, and the RSP2 has a fixed 0.200Mhz baseband filter (no matter what settings i use in gqrx or gnuradio). if i go over 2Mhz ...

i've been looking for a low profile antenna system for HF. i live in an apartment building and HF antennas are a bit problematic because of the large lengths of wire required. so i've been searching for something that's an ok antenna (doesn't have to be perfect, but has to be better than a dipole ma...

after a couple months playing around with the sdrplay and mostly gqrx, here's a few things i have found that might benefit new users. first, for most of this i was using a sample rate of 2Mhz, and a bandwidth of 1Mhz which is the default in gqrx images... there have been a few times i have found ima...

i just used my SDRplay to identify a noisy SMPS in my apartment.... turns out it's the charger brick for my 2 meter HT.... i was running a 10 hour waterfall of the digi portion of 20 meters (14000-14150 khz), and i noticed on the waterfall that one of the annoying noise sources i've been putting up ...
