  1. Hi Mark:

    I just bought a SE2 and applied for the rebate. But I'm not sure what to do with it now. I already have a Mode S transponder coded with an official code. I really only bought the SE2 for the ADSB in feature.

    I heard that you can't have two ADSB devices transmitting from one aircraft, but I read on the ADSB grant thread that someone programmed their SE2 with their nickname. If I did that and it was transmitting, I'd have two transmissions going but with different IDs. Is that illegal?

    Also, if my transponder is transmitting, will the SE2 pick that up? Ibelieve the SE2 can be set to receive only and just used as ADSB in. Are there other apps beside OzRunway that can interact with the SE2?
    Thanks for your help.

      I think there is confusion here -----

      . Mode S - SSR interrogation is  not to be confused with Mode S Extended squitter (protocol used for ADSB)- they are independent and simultaneous functions.

       

      1) if you have a Mode S transponder that ALSO has ADSB OUT - . Leave the Mode S transponder On and ADSB OUT  'ON', and disable the ADSB out (disable transmit on the sky echo) .  Why - becauset the transponder has 200W output on ADSB and will provide superior range (if you want superior range) . So yoru Sky echo does the ADSB-IN only to present traffic...
       

      2) If you have a Mode S transponder that DOES NOT have ADSB OUT (most of them unless it was upgraded or purchased recently, or built in), then you must leave the Mode S transponder ON,---- AND you run your SKy echo in ADSB Transmit and ADSB receive mode.  

       

      3) If you have a Mode A/C transponder - same as (2) , leave it on and operate Skyecho in  transmit and receive mode. 

       

      AN example of a Mode S transponder without ADSB is an GTX330. With ADSB that is a GTX330ES (which stands for "Extended Squitter- which is ADSB protocol)
      IMPORTANT NOTE : some transponders that support Mode S - ES MAY REQUIRE a software update to be fully compliant with ADSB formats.  You need to contact the manufacturer to figure out exactly what you have in the software installed to find out if you need a software upgrade .
      Note : some  mfrs provide a ADSB/ES upgrade to their Mode S transponders free of charge.

      No issue with Mode S transponder responding  to SSR  interrogations, and  ADSB broadcasts  from your skyecho. system copes with that.

  3. Thanks, might have to get a closer cut, I normally get a #2.

      as ya know , alot of these earcups- seal depends heavily on head shape, bones etc.....

       

      I have some colleagues who are using custom moulded silicon ear buds. they seal well in the ear canal.
