Phantom SDR Plus & RX888 - setup

[Martin G8JNJ]

Already done that several times, but I'm assuming it requires a manual Cypress driver install.

However, the new PC has just arrived, as per Bas's suggestion.

HP Elitedesk 800 G2 Mini PC i5-6500T 3.1Ghz 8GB RAM 240GB SSD

So I'll abandon the Gigabyte Brix, and spend the morning loading Ubuntu 22.04 and Phantom Web Plus onto it and see if I can make any further progress.

All of this is making the WEB-888 seem like a bargain, as the RX888 cooling modifications and the need for a higher spec (and physically larger) PC are all eating up my funds. I just hope the eventual outcome will be worth it.

Martin

Try different usb ports and double check all connections to the sdr

Martin,
just a reminder:
install first opencl and than PhantomSDR. You should do the PhantomSDR installation as "root".

good luck

John

[Martin G8JNJ]

OK, I have now got the basics running and lsusb reports the device as being present.

All installed as root. I have not installed opencl separately as I wasn't ware it was a prerequisite

I enabled and tried the various .sh files without luck then ran the https://github.com/Steven9101/PhantomSDR-Plus/wiki/Config-examples as suggested.

This was marginally more successful, but it gets stuck looking for the json marker file, and still no sign of the webservice running on the browser.

Thank you for using PhantomSDR+, you are supporting the Development of an Open-Source WebSDR Project ♥
Unable to open marker.json file.
No FFTW wisdom file found. Planning from scratch. This may take long on the first time but will then be fast.
Waterfall is sent every 2 FFTs

clinfo reports

root@phantom:/home/wessex# clinfo
Number of platforms                               0

After it says waterfall is sent every 2 ffts the website should be available on the port given in the config

[magicint1337]

After installing opencl you have to reboot to get proper clinfo output

[Martin G8JNJ]

OK some progress.

Tried installing OpenCL but even after several reboots Number of platforms 0

ran ./start-rx888mk2.sh

I can now see the web interface and tune to signals.

However, a signal on 198kHz is appearing on 211.22kHz the audio is choppy and agc seems to be pumping.

Should it all start automatically on reboot ? At the moment I'm having to manually do this.

[Martin G8JNJ]

Can anyone point me to a list of the rx888_stream parameters ?

e.g.

-s
-g
-m
-p

ect. ?

[magicint1337]

Well reduce the sample rate to 48mhz for now to reduce the stuttering, if you get opencl working then you can do 64mhz (which means 32mhz)

The signal should not appear at the wrong location.

For the agc a future update which i will provide this weekend will fix it.

It wont start on boot for now, you have to create a custom service for this.

[Martin G8JNJ]

OK, I found the help file.

OK I'll try reducing the sample rate.

[Martin G8JNJ]

Do I change the sample rate in the .sh file or the .toml file of both ?

[Martin G8JNJ]

OK, OpenCL now installed

root@phantom:/home/wessex/PhantomSDR-Plus# clinfo -l
Platform #0: Intel(R) OpenCL HD Graphics
 `-- Device #0: Intel(R) HD Graphics 530 [0x1912]

What config parameters do I need to change ?

[Martin G8JNJ]

You can now connect (on a temporary basis) at http://g8jnj.zapto.org:8090

BBC R4 which should be on 198kHz is actually on 211.2kHz

post your command and config file please
