Hi technic masters, When I connect to the SDR, I see that it is consuming about 130kB/s of bandwidth. Some of the settings on the SpyServer configuration affect the bandwidth used. Here are some of the settings I have that may help bring the bandwidth down: force_8bit = 1 fft_fps = 30 fft_bin_bits = 16 While some of my settings are higher than the defaults, this would add more bandwidth rather than reduce it. Its always a trade off between bandwidth and performance of the UI. In the spyserver.conf file provided out of the box by Airspy, they do a pretty good job at leaving comments for you to follow and they let you know what each of the parameters do (and how they would affect bandwidth consumption). My config file is relatively standard other than the settings I mentioned above. I hope this helps you with both of your questions.
I'll also add that if you are using radio modes in SDR Sharp that are like WFM, you bandwidth consumption will also go up noticeably. You can use the maximum_bandwidth = 15000 setting for most "narrow" modes like NFM, AM, USB, etc. You would not be able to listen to broadcast FM (WFM) stations like this, but it certainly would limit and lower the bandwidth consumption.

Hi deltaPath, I'm using SDR# (SDRSharp) revision 1811 (2021-03-29) on my PC to connect to the server and it is working just fine. Maybe you are using an older version of software or are entering the URL incorrectly. The url for the SpyServer Network should be sdr://sdr.kd0bqs.com:5555 Maybe one of these two suggestions will help you out.
It depends on the specific Airspy device and what sampling modes you are using. If I connect a dummy load to the SDR to eliminate signals, the floor I see is often over -120dBFS. Yes, the Airspy devices have better sensitivity than the RTL based devices. But, the Airspy devices also cost quite a bit more. Everything is a trade off! ;-)
I like this! Can you tell me how to choose the Airspy hardware so I can set one up for myself? Also, is their loop antenna a good choice to use indoors for someone who doesn't have any yard space?
The best way to choose a particular device is to start off by selecting a frequency range you would like to monitor. The Airspy HF+ and Discovery devices are particularly suited for lower frequency (aka HF) reception. About 30MHz and lower. AM radio would be received by these devices. he HF+ does have a 2nd port that can receive higher frequencies, but the device is best suited for HF. The R2 and Mini start at 24MHz and go up from there. FM radio would be received by these devices. There is another device called the SpyVerter that allows the R2 and Mini to receive signals lower than 24MHz, but you need to have another device and the cost goes up. Yes, a loop antenna is one of the better choices for an indoor antenna. You will have to re-tune the loop when you change frequency of interest, but if its indoor, this should be pretty easy to do.
😊woow amazing,i was interesting how that works for the militairy practice now here in the Netherlands Frisian Flag for 2 weeks in Leeuwarden.2022 .F 16 planes and more.thanks for the vido.greetz:🍐Peer.
@@mplmpl7780 yes once a second person or more connects then it locks down. If you are the only user, you can change the frequency to anything you like.
I would like to know how you get all the options listed on the left side of the application. It would make using AIRSPY easier and more efficient. Thank You Steve
sdr dongles are the gateway drug to ham radio. these things are game changers.
Brilliant. Thanks helping me get over the first set of learning curves.
Thanks for the video. I did not know that SDR# did this.
You're quite welcome!
Did you say "OLF" key of the keyboard
Very helpful. Thanks!
Any idea why i cant connect this airspy to my own rtl sdr dongle ?
Every thing looks good. But software says no device connected
I'm having trouble connecting to multiple SDRs...
even though they are green i get the error message ( airspy could not connect to sdr )
Nice Video, Thanks
Please how can i get the network bandwidth as low as you have it? arround 60kB/s, i have it at arround 600kB/s

i got the sdr but its hard asf the only thing i made to listen was am fm at the moment
It can recieve remote neural monitoring signals
This has been part of the narrative. Don’t you have to physically be outfitted with equipment in order to transmit?
I can't connect from Windows machine, getting: unsupported protocol version.. :/

Hi! Thank you for your video! Is it possible to scan a range of frequency (from..to)?
Can you please send me your already pre-setuped SpyServer? iam having some problems with mine...
Thanks for the video. What's the Airspy's noise floor? Do Airspy have better sensitivity than RTL (the blue dongle)?

Hi with your own sdr how many people can access how control the sdr at the same time? Thanks
It's currently configured to allow 5 connections.
