I realise you are just trying to recruit disgruntled
pilots to the COTS cause. They will be disgruntled
because their NAC will have rejected their claim.

I'll say it again, clearer this time and using shorter
words. The EW will log with any GPS but it will only
make an IGC file valid for a badge claim with one of
the approved GPS's, your NAC will reject a claim made
with an EW and any non approved GPS. You could, in
theory, build a circuit to inject valid datum sentences
into the EW, but any OO who let you get away with it
shouldn't be an OO and it's more effort than just using
an approved GPS.

Hehe, if there is no datum change from the GPS (like
in case of most
of the mouse type GPS) the final igc file will be the
same as if it were
from an approved Garmin. This is what I said. Yes,
it's against the
current rules, but who cares. Let's have their fun
with the valid igc file

Don't be misleading.

If someone tries to claim a badge using an EW and
a
'mouse type GPS' it will be rejected. The IGC approval
of the EW barographs requires the use of a GPS off
an approved list. The approved list GPS's output a
proprietary NMEA sentence for selected map datum which
is recorded by the logger to stop people displacing
turnpoints by changing map datum in flight.

I'm not saying this is the way it should be, there
is an argument for COTS loggers, but this is the way
it is, you can't claim a badge with an EW and just
any old GPS.

Or any other cheap mouse type GPS. The final igc
file will be fine
This badge&cheap GPS issue come up year by year.
Few enthusiastic
pilot joined and created COTS proposal to IGC but nothing
has changed so
far
