Pro Stick Orange v1.2 issue

Again, please accept my apologies. We will get you sorted out as fast as we can.

I’ve been told you have 100’s en-route to Amazon to replenish their stock. Are these problematic v1.2 units?

Some of the v1.2 Pro Sticks did go to Amazon. Please keep in mind they are only problematic if you want to use two of them on one Raspberry Pi. They are otherwise superior to the previous version.

Still waiting to hear how this is going to be resolved. Request 347027.

in what way are they “They are otherwise superior to the previous version.”??

@W6cz I just replied to your request.

@G6CMG our testing indicates that the Pro Stick v1.2 sees 10-15% more message traffic than the v1.1.


Sweet! Send me one…LOL What was changed on the hardware side to capture those results - and also will the 1.2.1+ also incorporate those changes?

What if a V1.2 orange is paired with a blue stick? Is this a problem too? That’s what I’m looking to do. And is the V1.2 orange a better performer than the blue stick for 1090 use?

That’s covered in the OP
(it’s not a problem)

It’s an entirely new PCB layout (and some component changes) which should, in theory, reduce noise and generally behave better. The prototypes seem to bear that out, though we only have limited results so far - the boards that went astray were meant to be for our next round of testing!

I appreciate the response from the FlightAware team. I got my orange stick from eBay today, looks like it is v1.2. Since I’m running with a Plus stick I’m not personally bothered by the serial issue, and I’ll happily take a small performance increase. Is there anything I can do from my end to assist with testing if that’s what these were meant for? Running it on piaware on the UAT side and feeding to FA, though it is only connected to my discone with no filter atm.

Worst combination.

  • A very wide-band antenna (discone) which picks much less of the desired signal, and a lot of undesired signals.
  • No filter to remove undesired signals picked by discone.

A simple 1/4 wavelength (76 mm at 978 Mhz, and 68 mm at 1090 Mhz) ground plane antenna like Spider will perform much better.

I know it’s nowhere close to ideal, it’s just what I already had up on my mast other than a 2m/70cm antenna and an FA 1090MHz one. I’ll be adding a proper antenna for UAT soon.

Sorry for the ‘detour’.

@obj…is there a new and improved Pro+ in the works, or is the Orange stick it?

We have updated designs for both the Pro Stick and Pro Stick Plus in the works.

We are also working on what we are internally referring to as the Pro Stick v2.0 which will offer significantly better performance than any of our other SDRs. Our second round of prototypes for those will be ordered in the next couple weeks and we hope to have those ready for sale by Q4 2020.

I promise we won’t accidentally ship those prototypes anywhere they shouldn’t go.


That’s good news, @esmathews, thank you.

I would not mind ‘accidentally’ receiving a Pro Stick v2.0 to test. I promise I won’t raise a ‘stink’ if you make such a ‘mistake’. :wink:

I’m becoming ‘lazier’ and ‘cheaper’, so the more you can ‘pack’ inside the new stick the better. :rofl:

My guess:
Among other improvements, changes include either an additional saw filter or relocation of saw filter immediately after the input sma connector.

Call me crazy, but what about a stick with bias tee and a new antenna with built-in LNA/filter combo powered by the stick?

This is off topic, but as it has already started, let me complete it.
Till you get a regular 978 antenna, you can add an indoor temporary DIY Quick Spider. It is made of Coax, an F-male connector, and requires an F-male to SMA-male adapter/pigtail to connect it to ProStick.

Even when located indoors near a window or attic, the Quick Spider will perform better than your discone on mast/roof .

For 978 MHz use radials and whip 76 mm. The 69 mmshown in the how-to are for 1090 Mhz
