Spyserver setup?

[dave3825]

Followed this guide and all went well. RTL-SDR Tutorial: Setting up and using the SpyServer Remote Streaming Server with an RTL-SDR and went with the SPY Server – SDR Server for Linux x64 download

But when I try to run, I get

pi@raspberrypi:~/spyserver $ ./spyserver
bash: ./spyserver: cannot execute binary file: Exec format error
pi@raspberrypi:~/spyserver $

Installed on Raspberry pi 3b+ running Raspbian.

What does this error mean?

Thanks

NOTE: That you will need to download the correct version for the platform that you are using (e.g. 32 or 64-bit, ARM or x86). Go to airspy.com/download, and find the links for the SpyServer download that matches your platform.

Yes, seems I downloaded linux 64 bit and not 32bit for arm boards ie:raspberry pi. Another reason I hate doing things from remote location. Got her up and running. Was looking to do for personal use but may make it public.

Next is to edit the port forwarding on router after I see how to increase the default bandwidth. When I run a p25 cc in fmp24, it works best at 12.5khz without any errors. But I can't get sdr any higher than 11,718 ...More reading after dinner.. Turkey taco time... Thanks @slicerwizard

I posted to airspy forum as I cant get any higher than 11718. Also can't get use full iq to be available. Stays greyed out.

Not looked at it for a couple of years but from memory I had to alter the maximum sample rate and possibly also maximum bandwidth settings in the config file before I got it running as though it was 'local'

 

[dave3825]

I played with maximum_bandwidth = 200000 and had it up to 400000 and still can't get nfm above 11718 and wfm 187500 .

I think it's hard limited somewhere. I can't go beyond that even after modding the file.

Read that back in 2017, a new sdr version came out and people were complaining that bw would not get up to 12500. Found a site with older versions and 1583 allows even higher than 12500. So since my raspberry is running SPY Server v2.0.1700, something changed in sdr's config or in the code itself after release 1583. After dinner I might try to compare configs for 1700 and 1583. Still cant enable the use full iq. Still greyed out.

There was some other limitation I found with the older one though. I think it was the overall bandwidth/throughput maybe. I wish we could tailor it to whatever...

I have an Airspy mini co-located with a BCD536HP at a tower on a scantenna up at 100ft. It's so nice to be able to access it remotely via spyserver but would be nice to get a full 12.5/25.
