Howto Run ADS-B Receiver + AIS Receiver on Same RPi

[Taxom]

Ok, I will try to do it myself, thanks anyway for the script, I constantly use it.

[Taxom]

Here is the first testing of the SAW filter.

But, something strange happened during the day, perhaps some kind of base station turned off.

@Taxom

How can I change the script so that after the update it will return the file with the settings back and restart the ais-cather

@Taxom

I just would like to automate updates so as not to wait for the completion of the update

 

DONE

Digi-Key sells only saw filter chip.

From where you purchased above assembled filter board?

Yep, you have 23+dB LNA build in the blue dongle.

@abcd567 you have any idea why spektrum will only show 1 dongle on my RPI when using virtualhere USB, I need to use the UHIDIR one as that’s my 162mhz dongle AS I want to do a spectrum scan between 100-220mhz to see what’s about.

@abcd567 you have any idea why spektrum will only show 1 dongle on my RPI when using virtualhere USB, I need to use the UHIDIR one as that’s my 162mhz dongle AS I want to do a spectrum scan between 100-220mhz to see what’s about.

The free-of-cost version allows to use only one usb device at a time. You have to choose which one you want to be used by Spektrum from “Vrtual Here Client” interface at Windows as shown in screenshot below.

To test both dongles, first select AIS dongle in the VH Client, and run the Spektrum scan. Next select ADSB dongle in VH Client, and run the Spektrum scan again.

[Jonseyt23]

I had the one I wanted to use selected in virtualhere client before I opened spektrum but would only show the one for adsb

[abcd567]

Both the dongle in “Virtual Here Client” on Windows are shown as RTL2838UHIDR, and their serial numbers 00000162 and 00001090 are not shown in “Virtual Here Client”.

To make it easy to identify, change product name of both dongles as follows:

(1) First stop piaware, dump1989-fa, and Aiscatcher

sudo systemctl stop piaware dump1090-fa aiscatcher

(2) Next insert only ADS-B 1090 dongle, and unplug AIS 00000162 dongle. Then issue following command

sudo rtl_eeprom -p RTL2838U-ADSB

When prompted, say yes

(3) Next unplug ADSB dongle and plugin AIS dongle and give following command:

sudo rtl_eeprom -p RTL2838U-AIS

When prompted, say yes

(4) Now plug out the AIS dongle. After 30 seconds, plug-in both dongles, and REBOOT

 

AIS and ADSB added to product name RTL2838U

[Jonseyt23]

@abcd567 so I have renamed both dongles as per your guide, but still spektrum does not list them after putting the AIS one in use on virtualhere client.

Hub has the IP of the RPI

[abcd567]

@Jonseyt23

Spektrum will list only ONE dongle, becsuse the “Virtual Here Client” makes available only ONE dongle at a time, the one shown as (In use by you). The Spektrum may not display same product name as the “Virtual Here Client” displays

[Jonseyt23]

That’s strange as when I click on the dongle in spektrum it just says cannot connect to sdr.

[abcd567]

Seems strange.
Restart Windows, and try again.

[Jonseyt23]

Nothing I have done will get it to work. Rebooted win pc, uninstalled from rpi, rebooted pi, reinstalled on pi, changed from WiFi to ethernet, still refused to open sdr on spektrum.

[Jonseyt23]

Think I’m going to have to reinstall win 10 as I can’t even run SDR++ without dll file errors

[abcd567]

@Jonseyt23

I’m going to have to reinstall win 10 as I can’t even run SDR++ without dll file error

It seems you hav an old version of Spektrum.

Download latest version 2.1.0 and try it

Figured it out, I had a brainwave and tried reinstalling zdiag drivers, and that got it working, im just hoping the biast is on as its the uputronics amp, it looks like it is, but dunno!

This is the scan between 152 &170mhz
