Instal SDR++ on your Mac. It supports SpyServer. I used MacPorts to install it. Fantastic software.

Thanks, Martin. Yes, I've successfully tested SDR++ with a Spyserver node and it does work great on macOS. There's still a gap for iPhone for me, though.

SDR++ ( https://github.com/AlexandreRouma/SDRPlusPlus ) includes support for the SpyServer protocol, runs on OSX (The readme.md explicitly mentions test builds using Big Sur 11.5), and android support is currently in development.
(ref: There is a "backend_abstraction" branch, last updated 3 days ago, looks to be where android support is being created. And it was mentioned on twitter that android support will be added if the current problems can be solved https://twitter.com/ryzerth/status/1496248402329354246 )

Neither of the clients mentioned are very specific about the server requirements, but it's worth a try ...perhaps with hfp_tcp and spyserver,

Did you really put the file where the software expects it to be?

Good day...

I just upgraded my installation to the latest version (1854) and see that the BandPlan.xml is not getting read properly.  I have confirmed that there are no typos in the file, and that it works fine with the earlier version I had installed (1840, I believe).

Has anyone else seen this behavior?  I confirmed that I disabled SDRSharp from writing out the file again on exit.  Looking for a solution.

Thanks!

In theory here, I think. Prog may be a bit preoccupied with an unspecified good thing at the moment.

Thanks, G3TDJ for the reply!

Do you need to run hfp_tcp server on Raspberry Pi in order to see it from the SDR Receiver iPhone app, Or does it have native Spyserver support?

Thanks!

Re: SDR# IF-Spectrum

Edward MacDonald
 

This is actually a plugin I made. It is not compatible with the current version of SDR# but I am working on this and many other plugins. However I have no time frame as to when I will be releasing an update but once my new website is functioning I wl let you know.

But the new IF-Filter display is only a flat curve without the possibility to see the carrier.

I added two screenshots:
The 1st shows the reception of a VOR station at 115,2 MHz with SDR# 1732. It is very easy to adjust the peak in the IF-Spectrum to tune into the exact frequency. In addition I can move the sliders L and R to change the IF-Spectrum bandwidth.
The 2nd shows the same carrier with SDR# 1842 with the activated "IF-Filter - Notch Processor" app. This is only a flat curve without sharp peak (seems to be very low bandwidth, but cannot be changed).

My question is:
How can I get a similar IF-Spectrum display like with 1732 also with the newer versions?
Is there a simple way I don't see actually?

Or is the new "IF-Filter - Notch Processor" not the same as the "IF-Spectrum" of the older versions? If yes: can I add an app "IF-Spectrum" to the new versions?
Or is there a way other than over the IF-Spectrum to exactly tune to a known frequency e.g. for frequency calibration purposes?

Emmanuel,

Thanks for the reply. I have also submitted a request to PA3FWM for the WebSDR files, but never got a response, unfortunately.

I would use Spyserver, but I would like to be able to do monitoring from my MacBook and iPhone, and, as far as I understand, SDR# is required on the client side to monitor an Airspy with Spyserver, which is why I was looking for a web-based solution. 


OpenWebRX is promising, but lacks some required functionality such as configurable tuning steps and has other issues that likely will not be resolved in the near future.

I can’t understand why WebSDR is so closely guarded.

Re: My BandPlan.xml not being read properly #bandplan

Correct, the location of the 'BandPlan.xml' file to edit is:  /SDRSharp/Instances/Profile1 or /Profile2.  Editing the file in /Profile1 worked for me.

Re: My BandPlan.xml not being read properly #bandplan

bgaphoto@...
 

After a few more hours of poking around, it looks like the latest version of SDR# has a couple 'BandPlan.xml' files down through the install directory.  Previously, the files in /SDRSharp/bin was the one that you would edit.  This was confirmed in the 'Big Book' documentation.

However, I found an /SDRSharp/Profiles directory, and within there was another subdirectory that also had 'BandPlan.xml'.  Editing that file and restarting the software addressed my issue.

Happy to pass along what I learned, especially if it helps even one person.  Awesome software, and love all the features!

Re: Airspy HF+ Discovery & WebSDR on Raspberry Pi

 

Hello is there a way I can get a copy of the websdr files?

the developer flat out refuses to give me a copy

it is the most blind friendlyness web sdr out there

I tried explaining this to him and he still refuses

thanks

A working test server is here : WebSDR on SV1BTL in Athens, GR  (the server is occasionally available only for test purpose). The server is working with "bands", because of 768KHz bandwidth limits of Airspy HF+ and Discovery receivers. This fact causes a mess when more than one user is connected, specially when there is a user who wishes to QSY. That's why I don't advice sharing your server to public.
Special thanks to OH5HB for modified driver - GitHub - ON5HB/hfp_tcp: Rtl_tcp-server for the Airspy HF+ and Discovery for websdr.org software. and SV2AMK for his help with band operation.

P.S. Although it possible to work with WebSDR and Airspy Discovery / HF+ using Rasspberry Pi 3 or 4, I think that SDR# and Spyserver is rather the best solution for sharing your receiver.

Thanks Al, bias tee power from the Pi is no more noisy than battery. None of the built in smoke has leaked out yet.
