What does your setup look like?

That howto is for Raspbian x86, and when Piaware version was 3.6.3. That is why you ran into dependency issue.

For latest version of Piaware 3.8.0 on Ubuntu 18.04 / 19.10, here are the instructions:

Howto Install Piaware ver 3.8.0 on Ubuntu & Debian amd64

Hi @abcd567…that makes sense. Thanks for clarifying and pointing out the new instructions.

Upgraded from a small magnetic base whip antenna to the FA indoor/outdoor unit. Already seeing an increasing trend in aircraft tracked and a decent increase in range. :+1:


Why are so many users using the additional FA filter behind the blue pro plus stick?

What are the advantages of doing it?

I’m not sure you are asking the right question, but the advantage of cascaded filters is, as you would expect - it will filter stronger out-of-band noise.

Technically i was able to imagine the answer by myself, but i wanted to know more some practical results showing the improvement :wink:

Please see this Nov 2016 post:

OK, but what if you’re already at the max with the Stick only? Does a filter improve this as well?

The 1090 MHz filter and LNA with its power supply are in a weather-tight metal box near the antenna. Power via the coaxial cable and a bias tee.

Nice setup.
The cavity filter is your design?

I’ll have to drop my system down to sort out some lower loss cabling before and after my filter.
At present it has a stack of SMA 90 degree and male to female adapters to connect it all.

I really should have taken a picture…

I deliberately didn’t when I rebuilt mine because people would laugh! It’s like my radio shack, untidy and messy but it works.


Talk with the tip floor neighbor. Maybe he’ll let you put the antenna on his balcony. A beer a month should be an appropriate rent :smile:

Did you grounded that metallic pole? Just in case of a lightning strike… You don’t want a flash to your house roof.

My indoor setup is: An older Dell laptop E6420 with an i7-2640M CPU, running Ubuntu 19.10, Airspy R2 receiver dongle, bias tee fed from an step-adjustable power supply, gas lightning arrester, RG6 cable to antenna outside (45 meter of cable).

My antenna setup is FA antenna, RTL-Blog LNA, grounding electrode pounded in the soil (only 4 ft long) and ground wire. I was concerned about bringing a lightning strike in the house.

I call that creative chaos. I’m a fellow practitioner :grimacing: :grin:
