To do next: either find somebody with a balloon, or a mountain to take it up. The former is probably easier in Suffolk. Meantime, if anybody has a transponder with altitude display it would be interesting to hear how this compares at height with the QNE figure on the PAW homepage (it’s in the pressure sensor data).

I'll take a look tomorrow - all our's have Garmin GTX 3xx's with ALT displayed ,...

Wifi Dongles don't have any battery backup

I assume you're referring to the GPS ..?

They take a note of their location when starting - if the GPS isn't where it's expecting to be after its last start up then it can take longer to get a fix and download the ephemeris /almanac data …

Have a read here … it interesting!! https://en.wikipedia.org/wiki/Global_Positioning_System

Evening

As has been mentioned on a recent post, what protocol are you using to connect SkyDemon to your PAW .? (when you select 'Go Flying', what options do you have ..?)

If you're using the GLD90 method then you'll not get bearingless targets - ie, Mode C/S

The RAM sucker is held onto the PAW with the 1/4 thread screw and a small adapter to hold it to the sucker

I'll snap more pics of the components I used to do this and add later

Power wise, ditto what Peter said, but if you're looking for a GOOD cable, Juice Bitz do a short one with a right angle on the micro USB end - I use these (with a guard protecting the exposed micro USB plug) and they work as well as the supplied PAW cable - they are still 20AWG and available in a few colours (I use the purple for Micro USB and light blue for Apple / Lightning)

Hi all.

As mentioned above, a few more pics showing the PAW mounted in the left side of a R22 (it's the same for a R44) along with a pic showing the mount with 4 holes on the rear of the PAW (the GoPro style one) …

Hi Ryan

From your post ….

"I've been using this mount for now, while I am trying it out, as recommended elsewhere on the forum:
https://www.amazon.co.uk/gp/product/B0725H9JY4/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1

I'm using a dual-suction proper RAM mount for the iPad but that was expensive so wanted to see how things went first. I have the Rosetta which looks a lot bigger than the one you are using and has two aerials so I definitely need to find a slimmer mount. I notice there are a group of 4 slots that look like they could be a better way to secure it (as the thread kept getting loose) but I haven't seen an attachment for the RAM suction for anything like this. "

My case is the same size as your Rosetta (it's the same case but clear - it just gets pulled apart frequently due to different parts being tested), and the antenna setup is the same too ...

I have one of the mounts you've linked to - its fine but I went with a slightly modified RAM sucker and a 1/4 thread adapter to mount to the case (again, pics tomorrow) - it ends up slightly closer to the canopy , and has less tendancy to wobble...

With a battery strapped on I'd not use the 4 slot style mounts due to the extra weight but your mileage may vary ... there isn't a stock RAM adapter for the 4 slots as far as I know ..

Power wise, the recommended ones are from Anker (Powercore) as they provide sufficient current to power the PAW - they are avaiable in different sizes and therefore different run-times - I use the Dell Power Companions and they work well for me ... they usualy run all day (12000 mah) with the 18000mah one going for around 18 hours ...

Cheers

Hi Ryan

I use PAW in a variety of different heli's depending on what's in the schedule on a given day.

I spend a lot of time in Robinsons, both the R44 and R22, and here's my take on mounting ...

My PAW is in the same style case as yours, with a battery pack strapped to it, and a RAM sucker mount fixed to the other side

If I'm flying from the left seat, or there is a passenger in the left seat with the dual controls removed, I mount the PAW on the canopy , low down and above the pedals using the sucker mount. keeping it close to the instrument binnacle reduces any 'blocking of the view. If in the right seat I sometimes put it on the canopy on the right side, just above my shin (again low down) with the ipad mini in front of it, closer to me … Using these positions I still have plenty of 'view' available ….

I then mount my ipad (I use a mini in  Robinsons, and an Air in other stuff), again on a RAM cradle with sucker mount,  on the canopy, above my knees and as close to the door as possible (it's well away from the controls)

Keeping the PAW at the front of the aircraft minimises the signal blocking from the engine (there will always be some blocking from the 540 / firewall / MRGB behind you)

I've attached a couple of pics (one from outside, one from inside) showing the PAW in a R22 (I use the same place in the R44), and will add a shot of the ipad / PAW when back at the heliport tomorrow so you can see what I'm getting at ..

One thing you don't mention is the type of suction mount you're using - a pic would be handy....

I've just received an updated Rosetta case from one of the engineering team with suckers that are more closely integrated into the case (and they're smaller), making the whole unit a lot smaller (than mine anyway ..) and I've just started to test it to see how it fits on a heli canopy, and also how the suckers stand up to the vibration - I'll carry on with the test for another week or so and report my findings …

Regarding the GA traffic that you saw, but PAW didn't, what are you're settings for distance / heights / modes etc etc from your config page ..? there may be something that needs a tweak in there, but do remember that Mode C traffic will only be picked up if it's been painted/interrogated by radar and is therefore broadcasting … I see a fair bit of GA from time to time that PAW doesn't spot - some I know don't have a transponder, and others have been out of sight / range of a radar installation.

Hope this helps

Cheers

I think Stodge may be referring to the SD Card adapter for the Micros SD Card that's in the Rosetta

The Micros SD card as Ian has said can be thought of as a small hard drive - if you look on the Rosetta you'll see a finger sized dimple on the case between the two antenna's - this is where the Micro SD card is (it's plugged into the Raspberry Pi and can be removed if necessary) . A Micro SD card is about the size of a fingernail.

The full sized SD Card is actall the adapter for the Micro SD card and this allows you to connect the Micro SD card to a PC etc assuming you have a slot for it or a SD card reader.

Hope this makes sense

Cheers

Hi

If your Zulu control box looks like the attached then it's Bluetooth …(see the 3rd button up with the Bluetooth symbol on it)

I use two of the Low Powered ones in the main PAW setup - the work perfectly, reasonably cool too !

And regarding the no traffic display - it might just be that there isn't anything out there that's detectable at that time ? …

Ditto to the above …

Make sure both ends of the power cable (Micro and normal USB) are snug …

I have several mounts depending on the aircraft in use (all Helicopters) and they do move around (some of the egg beaters are not the smoothest on start up / shutdown..) Even the sucker mounts stay put, but I do check the power connections now and then to ensure that they're all tight...

In theory, not that tricky  from a pure left / right point of view.

Front to back adds extra layers of complexity that the Pi may well object to !!

I've spotted this as a potential problem and have added a guard to the top of my test unit to prevent the Powercable being knocked when moving the unit around from machine to machine

I've changed the straight PAW power cable to a JuiceBitz angled one (at the micro USB end) - it's still rated the same as the stock cable supplied with a PAW (20 AWG) and doesn't cause any power problems.

The guard is held on with Velcro so can be removed if necessary to access the cable and port.

It's not pretty, but it does work.  The power cable is shown removed in the pic as I've been using it with desk power whilst working on it
