I have had an ADS 600B for several years and do love it. I have a question however for those in the know. The normal situation is to have the barometric altitude input to the Navworx unit. Now they offer on the EXP as an alternative, the Transmon unit that "reads" the transponder output. But transponders don't transmit baro altitude; they transmit pressure altitude (IE QNE 2992). How does this work? The Navworx box with the transmon sensor would not know the QNH (local altimeter) setting. Can't figure this one out! Can someone explain this please?

That being said, the next person who speaks with Bill Moffitt at Navworx needs to suggest that Bill place some real communication on his website. I would bet that most people will understand production delays if only Navworx would post in writing just what is going on! Silence is very frustrating to all who are awaiting delivery. I am waiting for the software change that will make me 2020 compliant that I was told about in April. Haven't seen it yet either.

FAR91.227 (3)(c) says you must transmit out pressure altitude. And your gps position source provides true altitude.

Pressure altitude (29.92) is provided from a seperate altitude encoder or air data source to the ADS-B unit, this must be the same source that is used by your transponder.

The Transpon unit only sniffs squawk code, not altitude.

The conversion to local altimeter setting is accomplished by ATC computers. All transponders and ADS-B equipment broadcast altitude ref'd to 29.92.

To the best of my knowledge GPS altitude is not used by ATC.

According to Bill, the Transmod unit gets squawk code AND pressure altitude from the transponder antenna cable.

I stand corrected, apparently the Navworx can get altitude data either from an encoder or the transmon (unlike all other ADS-B units).

Default update

I received an email moments ago, looks like another price increase.
here is a copy of the email.

ADS600-EXP Status
This email is for those customers who have yet to receive their units.

First, I want to apologize for the amount of time that has transpired without getting you the products you ordered and paid for. After years of AOPA and others telling their members (of which I am one of) not to equip with ADS-B, just this spring they had a change of heart and advised their members to equip. That brought on a huge demand for both our certified product as well as the brand new ADS600-EXP. We had several problems with the -EXP in the early stage as well, which didn't help our initial production run. Combined demand then quickly exceeded our capability to produce so we made a decision to stop all production to invest in new and (much) faster production equipment. Unfortunately this required us to sustain a down-time of nearly two months. I'm now able to report that we're now back up and in full production and starting to fill the current backlog of orders. THANK YOU for being so patient for all of this time.

Of course for those who don't wish to wait any longer; our offer of a full non-conditional refund is cornerstone to our business philosophy, so please contact us if you need to cancel your order.

Currently we are looking to fulfill all back orders in the next 3-5 weeks. For those of you who have early orders but can wait a little longer, please let us know; there are some customers that ordered after you but have flying aircraft they wish to install now. We will reward you with a NavWorx baseball cap for your sacrifice

If referring our products to a friend, please be aware that we'll be raising prices on all products at the end of this month.

Thank you again for your patience and support.

Default RESTATE earlier request - -

PLEASE - if an RV-12 owner with a D-180, I ask that you take pictures of your install, and instructions also for a successful installation. I am waiting for an EXP unit. We can help each other get these working properly and save each other time. I will do so, but if you get yours done first and know it is working properly, please share to save us all time.

THANKS !

Default 600 EXP shiping Update

Just got a response from Navworx on their next projected delivery date.

Looks like at position 22 it will now be Mid November or 10 months since ordering. My TransmonSPE, both antennas and wiring harness have been installed in my 2005 RV7a since April.
