Would it be a problem to fix the GPS antenna of the EW MicroRecorder next
to the FLARM antenna?

It could be. You can get interferance between the two.

In answer to an earlier question, it you put any antenna in your pocket, it
could be masked by your body and inhibit receiving from some directions. A
clear view if the sky is always the ideal.

Would it be a problem to fix the GPS antenna of the EW MicroRecorder
next to the FLARM antenna?

What Tim said. I modified my battery box lid which, in a Libelle is a
convenient place to mount the Microrecorder and its GPS antenna. Here's a
pictu

https://www.gregorie.org/gliding/lib...ttery_lid.html

The battery box lid is a sandwich of 1.6mm epoxy-glass plate and 3mm
balsa sheet. The GPS antenna is on a 50mm high support: its a V-pylon
made from two pieces of 1.6mm epoxy-glass plate glued at 90 degrees to
each other with another piece of epoxy plate glued on the top. I use
Velcro patches to mount the GPS antenna on the pylon and heavy duty
Velcro patches to hold the Microrecorder in place on the battery box lid.
The enclosed structure to the right of the Microrecorder contains wiring
that powers my panel and the Microrecorder:

- The two SLA 7Ah batteries in the battery box are fitted with short
(150mm, 6") cables and XLR plugs. These go to XLR sockets under the
right edge of the box lid which connect the batteries to the fuses
marked A(vionics) and R(adio). Connections from them go to the XLR
socket (top front) which feeds my panel via a three wire cable.

- A diode connects to each battery to the left-most fuse. This supplies
external power to the Microrecorder via the rocker switch behind the
tiedown bolt and the socket that connects to it.

This arrangement lets the Microrecorder draw from the either or
both batteries depending on which has the most charge. The diodes
prevent the strongest battery from trying the charge the weaker
one.

The rocker switch is needed because of the way the Microrecorder's push-
on - push-off switch works:

- if external power is NOT connected the switch works as you'd expect and
turns the logger on and off

- if external power IS connected, the Microrecorder is automatically
powered on and running. It will automatically top up its internal
battery from the external power if needed.

If you disconnect the external power the Microrecorder will continue to
run until you turn it off using its power switch.

This is both a blessing and a curse. The good point is that the
Microrecorder will have a complete log of your flight even if your
electrical system has a total failure. The downside is that, if you land,
derig, put the glider away and drive off home without turning the
Microrecorder off, it will still be running and will continue to do so
until either you notice and turn it off or its battery goes flat.

The Flarm manual advises you not to install the Flarm GPS within 30cm of the Flarm Antenna. It would be the same for your EW Antenna

I have an EW myself. It is connected to my Android phone via a IOIO box. I run XCSoar. I can declare a task to the EW with this setup but cannot download a file.

The Nanos can connect via bluetooth which is a bit easier. You can declare a task with bluetooth but cannot download a file.

Having used both, there is not a big difference other than the Nano has bluetooth.

The nano config app allows downloading of flights over bluetooth. I've
done this with the android version. See section 5.3 of the nano manual
which describes the process.

I used an old EW MicroRecorder (pre-SD card version) for a number of years. Always a bit of a hassle to have to do the declaration from a PC and having to have a laptop at the airfield etc. The aerial is also separate and so has to be stuck somewhere and then plugged into the unit prior to the flight. But the unit was generally reliable and easy to use.

I have just purchased a Nano4. Was looking at the Nano and Nano3 too - but liked the airspace warnings as well as final glide and climb optimiser which are now part of the Nano4. The NanoConfig App and Bluetooth connectivity mean declarations can be done from an android cellphone saving the hassle of having to connect any of the Nano units to a laptop for the declarations. Flights can also be downloaded using Bluetooth. I hate cables generally. The battery life is also far longer than the EW and its a far smaller unit overall. I personally think the extra Euro100 is worth the expense considering it is a far more modern unit. Both types are approved for all flights.

Hmm, good points. I always used FLARM in our club's gliders to record flights and used my phone as a GPS, maybe the Nano4 would be a good replacement for both. Do you need any other connections to the Nano/Nano4? Vario for example, or can the GPS register the differences in altitude automatically? Thanks!

I have just found the apps, they look very easy and I'm able to use my phone as well. Getting the regular Nano without display, would that be possible to mount it to the side of my instrument panel? Does it require to be put in direct view of the sky?

The Nanos' are all totally self-contained. Have built-in antenna, battery, pressure sensor, GPS and noise sensors. Can literally slip it into a pocket and forget about it. Very long battery lives. They look like great little units.

Does it matter where you place the Nano? For example, just like you said, in a pocket (side bag for example)?

Well - I plan to mount the Nono4 where it can be observed and have a suction-cup mount for it already (a suitable generic cellphone mount). However, my understanding of the Nano is it can be put into the pocket. That can be confirmed with LX Nav.
