Rich is correct. That is why Roger got in trouble. They couldn't sell the portable in the US so he bought one out of England

I have it, I bought it from a vendor in England, for around $500. I used it for a year and it worked well. The FAA sent me an email telling me my transponder isn’t working. I don’t have a transponder and told him what I was doing. He politely told me to stop broadcasting. I’ve use it as an ADS/b in since then. I did set it up with my correct mode S code and tail number. I was honest and I bit me. I figured they’d be able to figure it out using tower tapes and adsb info.

Roger was passionate about being seen in the electronic aviation world.

Richard in OH who found using ads-b at 500 to 1000 AGL too distracting my obligations to see and avoid.

[Don Harvie]

If it’s to deal with drones etc. you might be thinking of this.

In the UK, Australia and New Zealand we’re allowed to use the uAvionix Skyecho 2 (an EC - Electronic Conspicuity device) which is a portable ADSB in & out solution. It doesn’t replace a transponder with the full mode C reply, but it does transmit the ADSB out for other aircraft to see. (ATC here filter out EC devices so its no good for controlled airspace). I have one that I move from aircraft to aircraft and my EFB software automatically connects to it and updates the hex code for the ADSB identity based on the aircraft I’ve selected in the EFB app.

The skyecho is a 1080MHz ADSB and it doesn’t do the UAT978 ADSB which I think is what is used in the US.

Don,

The SkyEcho is what I have. FAA won’t let us use them. I assume, because it’s using GPS altitude and not pressure altitude.

Duane,

I always thought that the ADSB signal referenced gps altitude. It’s the transponder that has the pressure altitude which is missing unless you have a mode C transponder and the SkyEcho together.

The SkyEcho is a 1090MHz ES device only, which I understand, in the USA is only used by airliners above 18000 feet. For GA below that altitude low ADSB uses 978MHz UAT which means using a SkyEcho in the US, all the other GA ADSB-in users wouldn’t see you anyway. Our ADSB here in Australia and I guess the UK and NZ only uses 1090MHz ES irrespective of Altitude.

I’d say it’s likely the latter reason the FAA don’t want you using them, because you could potentially use and have an older Mode C transponder and the an EC device in which case you would be sending pressure Alt from the transponder, and thinking you had adsb capability by virtue of the EC device, but in actuality weren’t visible to the the other 978MHz UAT ADSB users below 18000’

While were allowed to use EC ADSB in/out devices here in Aus, it doesn’t get us any access to controlled airspace in our bug smashers. Their primary value lies in having aircraft to aircraft visibility.

After I read all this. Can we use a portable adsb or not!! I been wanting to be seen for 5 years now.  I brought it up at a big wings meeting Many years ago. Even if it is off a little another plane will know we are there. Better than nothing. I told the FAA I am willing to buy a portable device. I own 3 aircraft... 2 experimental a Pietenpol, a Super Baby Great Lakes and a Aeronca Chief.. I have 2 Stratux in adsb's with I-fly. Works great..

[Duane Fey]

As I understand it, it’s against regulations to use a portable ADSb.

[Mark Peterson]

My understanding, regardless of sailplanes in local areas, is that the portable isn't approved do to concerns over power source failure, calibration and the ability of them to be put in a car trunk and driven off.  ATC really doesn't want to chase down those targets, even though they aren't used as a primary in my understanding.   Might change, but I do agree with Richard that even having a Stratux in the cab directs your scan inside rather than outside - and half the targets that show up are much closer on the screen than they are in the real world.   About half the time, that big dot on the screen is a 1/16" at arms length target in the windshield.  Good to know, good to keep it in balance in the scan.  Fly like a feral cat.

Us older pilots would rather “see” and avoid.  Kids, today, that grew up with devices, rely, too heavily, on their iPad and ADSb.  My main issue is I’m flying an invisible, non-electric, airplane, often under the mode C veil.  Most pilots don’t realize that non-electric aircraft are allowed under the veil without ADSb out.  I want to be seen.

I hear ya. . .

Flying under Seattle B in the mode C veil, my first comment to any pilot is "you know, there are lot of us flying that aren't required to have ADSb and it's still VFR rules regardless of the electronics in the cockpit."  Most know, but you do get surprised looks.  Don't know what CFIs are teaching people, but there is a knowledge gap.

A receiver, Yes.

[alan miller]

The knowledge gap is huge.  As a DPE I have about 2 percent of the applicants that understand no transponder is required in the Mode C veil.  It’s scary.

Correct me but no transponder is required only it your aircraft doesn't have an electrical system and you need a generator or alternator to be considered an electrical system 

Richard in OH who flys 500 to 1000 AGL without an electrical system 

[Duane Fey]

That’s my understanding.

That's my understanding too.  No engine driven electrical, no transponder.

Yes that is correct Richard.  South of Atlanta in the mode c veil we have about 500 air parks with a couple million Cubs, Champs etc with no electrical- yet the pilots that fly the Cessnas and Cirrus’s believe that they are GUARANTEED to see the other planes on their gizmos while flying in the Mode c Veil.  

It is amazing we do not have more midair’s than we do….

[Mark Peterson]

Yes, I really think that the whole thing with newer pilots is an added risk.  I'd have them start all flight instruction without it, for the first 10 or 15 hours. Flying among the Microsoft people, they are so screen oriented and want to fly now that they can afford it, it's really feeling more risky than it was 15 years ago.  Add to the mix factory CFIs who barely know more than the minimums and it's just disheartening.   Used to be a point of pride to do VFR and enjoy it.

It's true... And the 'any traffic in the vicinity advise' travesty is the same deal: aircraft without radios? Not possible.

I would really like to have a portable xponder + adsb dohickey just so I show up on the screens of these people who aren't using their eyeballs other than for their screens.

In their defense, of course, some of the electronics packages are so complicated that it takes pilot plus copilot to handle the load. A friend of mine recently paid several hundred dollars for an hour in a Cirrus, and was struck by how all the work of managing the flight through the electronic devices made the flying much less enjoyable.

A Cirrus to me is a tool to get there. Unless I did a lot of flying for work, I think I’ll stick to my simple airplane and have fun getting somewhere or nowhere.

I live in the DC area. There is a flight school here ( Welcome to Aviation Adventures -- The Flight School Pilots Love )  that has locations both inside and outside the DC SFRA. They had (have?) a 65 hp 7AC Champ that had ADS-B running off a battery so they could fly it in and out of the SFRA. I'm not sure how they got it done. I believe they either had a 1090 transponder replacement ADS-B solution or they had a separate transponder installed as well, which would also have had to be running off the battery. Their Champ was crashed on a training flight, so it is out of commission right now. Not sure where they are in the process of getting it back together.

Amen John.

When I soloed in a Cessna 150 58 years ago all I wanted to do was feed the wind beneath my wings and appreciate the endless vistas that I was privileged to witness. Today I still fly for the same reason; getting someplace is an added benefit. TAA are great if you are going x-c into high traffic areas or busy airports, but my joy of flying is low and slow looking at all earth below and in front. Much has been written about instrument scans as well windscreen scans. One is for IFR flight while the other is for VFR and the two should not be confused for their intended purpose.

I always carry a handheld for x-c trips and rarely use it at my home airport. Without a radio, I enter the pattern at 700-800 AGL upwind, crosswind, or downwind which affords enough time in a 70 knot Chief or Champ. My downwind leg is close-in and opposite where I want to land I close the throttle and dead stick it on the runway. From the time I turn base until I clear I live in fear of those five-mile-final flyers who believe that since they declared final they don't have anything in front of then.
