Hope to get the samples to test soon.

Adi,

Keith is (of course) correct that the thicker ‘back end’ of the SMA on the type of splitter where both pigtails originate at the SMA (as opposed to being spliced in part way along the cable) won’t fit into the cutout in the Rosetta Bridge. I suppose we should refer to this type as a ‘V’ splitter rather than a ‘Y’ splitter.

It does however fit perfectly in the antenna cutout underneath the Raspberry Pi, with the pigtails routed out through the small cutouts beneath the USB / Ethernet Ports at the other end to the SDRs.

Apart from the extra dongle reporting in the USB devices section at the bottom of the Home Screen, there is no other indication until 978MHz data is received, when this will be reported in the ‘ADSB’ row of the Homescreen (see screenshot). (On that occasion BTW, I didn’t get enough data to give me a full weather picture and haven’t been back south since).

Regards

Peter

Well, my cables arrived today for my Pilotaware and that of a friend.

I found they seemed to fit ok so long as you have the cables parallel to the board.

So that's two more Pilotaware's that can receive weather now to fly somewhere that transmits it! guess the cost and ability to join the transmission of weather trial as a ground station is costly?

Hi Adi,

Well done. Just a minor point - I notice your Homepage is indicating ‘Throttled=0x50005’, which indicates a power supply issue possibly due to adding the extra SDR. I take it you are using the standard power cable. Just check your supply is rated to supply a minimum of 2Amps at 5 Volts.

Regards

Peter

I wondered what that was! I’m using a 20swg short cable and a 2.1A battery pack!

Strange, that should be ok with 2x low power SDRs - mine runs that and a fan! If it’s running, keep an eye on it and let us know what happens.

Ok so here are my non scientific findings!
I have two battery packs one states 2.4A out the other 2.1 cpu shows throttled hex 50005 under voltage.

Plug pilotaware into a pi mains supply OxO so all ok

Plug the Pi into a 3A mains usb supply using the same cable as with the battery packs 0x0

Using a different 20awg cable with original battery 0x50005

So looks like only certain battery packs will do and my Rav packs are not good enough 😭

Peter, which battery pack do you use?

Also where are you picking up the 5v for your fan?

Last question :)
Do you think the more efficient power supply in in the 3B+ will overcome some of these issues when it’s suppoted?

Hi Adi,

1). In the plane, I use a Charge 4 power supply https://charge4.harkwood.co.uk

A cheaper alternative I have also used is the Anker PowerDrive 5 https://www.amazon.co.uk/PowerDrive-5-Port-Charging-iPhone-Galaxy/dp/B00OUK0N26/ref=sr_1_1?s=electronics&ie=UTF8&qid=1530569809&sr=1-1&keywords=anker+powerdrive+5

For testing, I normally use a couple of Anker 20100 packs - have a read at this thread, especially the recent posts... http://forum.pilotaware.com/index.php/topic,9.msg15362.html#msg15362

2). The Rosetta Bridge has a 5v Out supply, (marked on the board) to which I have connected a small fan, though this is not an ‘official’ mod, so if you decide to do so, be careful.

3). I can’t say yet whether the Pi3B+ Board is more efficient as I haven’t had time to test that yet. I’ll let you know if/when I do.

Regards

Peter

 N.B. for the benefit of anyone else reading this we have (as you would expect) done some preliminary testing with the newer Raspberry Pi3B+, but the current PAW software won’t run on it.

Did somebody recommend this type of powerpack ?
I am unfamiliar with this, we only recommend Anker and Charge2/4

Thx

Hi Lee
Can you tell me a bit more about the throttling procedure.....Does the display throttling only remain while there is an under power condition..... I have just noticed I also have this condition albeit with the twin SDR's (low power), a juicebitz 20 AWG cable......and anker 20000mAH battery.....I have also run it from a known 2.4a mains power supply and can't remove the condition....what effect does it have on the processor...? And once triggered does it remain on the home page or disappear once the correct voltage is reestablished.
Kind regards
Brinsley

from here: https://www.raspberrypi.org/forums/viewtopic.php?f=63&t=147781&start=50#p972790

Code: [Select]
0: under-voltage
1: arm frequency capped
2: currently throttled
16: under-voltage has occurred
17: arm frequency capped has occurred
18: throttling has occurred

Brinz - do you get the same effect if you boot with a single SDR ?
Which Low Power SDR have you obtained ?
I recall there is a v1 and a v2, we supply the newer version.

Thx
Lee
