*The FLARM defaults to 19200 baud and
the SN10 defaults to 4800 baud. *If you have somewhat recent software in
your SN10 you can set the baud rate to 19200.

That did it! So,if you want to drive the SN-10 with FLARM GPS, you
need to select 19200 baud on the NMEA (SN-10 page about 3 from the end
in setup mode). Now, I can leave the Garmin GPS off and only use it if
the FLARM GPS fails, saving about 100 m/a. I still have 2 GPS's and 2
flight recorders working all the time.
Thanks Paul

I read the amps as I turned on all equipment and got the following.
Dittle radio---.09
Alt encoder----.25
Becker Tnspdr--.2
Model 20 GPS---.11
FLARM (tracking).1
SN-10----------.17
B-400----------.1
With all the above on, GPS tracking and FLARM showing a target, I read
1.02 amps total. When I transmitted on the radio---------2.3 total
amps.

Cheers,
JJ
