I was wrong. TIS-B and ADS-R are available on 1090 frequency. However, older boxes, like the Garmin 330ES only receive TIS-A. The Garmin 335 does not receive any TIS. Apparently some of the newer boxes will receive TIS-B on 1090. None of the 1090 boxes can receive FIS-B. (weather) without a 978 receiver. Some of the boxes like the L3 Lynx 9000 and Garmin 345 contain both the out and a dual frequency In receiver to allow receiving all ADS-B equipped traffic directly, aircraft to aircraft, but still need the ground stations to see non-equipped aircraft. To quote from Garmin: "Will the GTX 330 ES, GTX 33 ES or GTX 23 ES transponders display traffic via the FAAs TIS-B ADS-B uplink? The ES transponders currently have the capability to uplink the FAAs TIS-A traffic (consult the question below regarding differences between TIS-A and TIS-B traffic). There are currently no plans to update the transponder to uplink from TIS-B." Basically I'm not seeing many 1090ES transponders that include a TIS-B or any other form of traffic receiver, except as an optional extra, and it makes more sense to get a dual band receiver if you are concerned about traffic when you are out of sight of a ground station. Dual band is only showing up in the newest units. Having a portable receiver that displays on a tablet is nice, but isn't the same as having traffic and weather on the instrument panel.

There are portable receivers that will interface with an EFIS mounted in the panel. GRT, for example, will interface with multiple portable ADS-B receivers, including the Raspberry Pi based Stratux system, while at the same time being able to display the ADS-B information on a tablet. -Dj -- Dj Merrill - N1JOV - EAA Chapter 87 Sportsman 2+2 Builder #7118 N421DJ - https://deej.net/sportsman/ Glastar Flyer N866RH - https://deej.net/glastar/ ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message aeroelectric-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/AeroElectric-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/aeroelectric-list Browse Digests http://www.matronics.com/digest/aeroelectric-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
