Mike,
Yes, I have an MGL system and their latest GPS, the SP-12
<http://www.mglavionics.co.za/sp12.html>, has the necessary certifications
to be an ADS-B source. Rainier has posted the details but they were so
detailed that my eyes glazed over while reading them. The bottom line is
that the SP-12 is certified but the GPS which is integrated into the EFIS
is significantly more accurate. Go figure.
I am seeking a navigation radio with a GPS receiver that I can use for
flying IFR so I want both the necessary certifications *and* the database
with approaches, SIDs, STARs, etc. And I want a proven user interface that
someone else has already designed and debugged. I am willing to do a lot of
experimenting but, when I am in the clouds, I want to minimize my risk and
workload.
The MGL SP-12 is only GPS receiver, though. It lacks a front panel display,
database, etc etc etc, so it won't meet my needs.

Thanks Bob; the trim.pdf is a good starting point for me. Unfortunately, I

| Subject: | ADS-B Preflight Requirements updated for GA |
Just saw this on AVWeb...
The FAA will issue a Notam
<https://www.faa.gov/nextgen/equipadsb/resources/media/guidance_adsb_out_operations.pdf>
on Thursday that will essentially exempt general aviation aircraft
operators from an ADS-B preflight requirement when the ADS-B mandate
kicks in next January. The Notam specifically exempts ADS-B Out
transmitters that use WAAS GPS receivers as a position source from the
preflight requirement described in an FAA policy statement that was
released earlier this month. The Notam reads: It is not necessary for
operators of aircraft equipped with the Wide Area Augmentation System
(WAAS) (TSOC145 or TSOC146) receivers to conduct a preflight
availability prediction.
Garmin spokesman Bill Stone told /AVweb/ the preflight requirement was
always intended for airliners, most of which have early-generation GPS
systems that are not as reliably precise as those with WAAS. All ADS-B
units certified for GA aircraft for the 2020 mandate must use a WAAS GPS
receiver as a position source. There are currently zero non-WAAS based
ADS-B Out GPS solutions for general aviation aircraft, he said. For
GA, its a non-issue. Stone said he suspects the WAAS exemption got
lost in the extensive vetting process that policy statements like the
preflight requirements included in the recent Federal Register Notice go
through. The original intent of the policy statement was to codify
exemptions from sanctions for airlines when GPS signals degrade after
theyve done the preflight checks and the subsequent lack of compliance
is beyond their control.

Got a VNA up and running on a laptop.
Will try to get a Jim Wier ELT antenna
fabricated over the next few days to
see if a common mode choke is really
effective/necessary.
I'll also look at an exemplar
Pawsey Stub and a legacy 'Aviation
BALUN' featured in so many anointed
documents over the past 50 or so
years.
By the way, I was curious about how
well those little VHF/UHF 'rubber duck'
antennas worked on contemporary VHF/UHF
hand-helds. Screwed an antenna off my EMS
talkie to the VNA and ran a 100 to 500 MHz scan
which yielded the following plot:
Emacs!
Sho 'nuf . . . the little critter has SWR
'dips' that span the frequencies of interest.
Pretty cool . . .

I had the IFR GPS from GRT but they didn't have the software updated. So I went
looking for a GNS400W (or 400 that I would upgrade). For the same price I was
finding them, Tim and Approach FastStack got me a brand new GTN625.
Took me a while to get used to the different UI, but it's pretty nice.

As Art points out, there are radical differences between a 'WAAS certified
GPS' as a position source for ADSB, and an IFR certified GPS navigation
radio. As far as I know, there are no experimental EFIS systems that are
approved for IFR *navigation*. Perfectly fine to use them as flight
instruments in IFR conditions, but until the FAA modifies their rules, you
still need an IFR certified GPS navigator (complete with certified, up to
date databases, approaches, etc) for IFR GPS navigation in the USA. I've
seen some rumors that FAA might be considering an easing on that rule, so
that non-certified GPS could be used for IFR, similar to non-TSO VOR/ILS
receivers, but haven't heard of any official change.

Hey Art,
Don't know your budget, but an IFR rated friend replaced his Garmin 430
with an Avidyne 440. Slide-in replacement for the 430, and he says that
it's got a much better user interface and some really nice features that
'anticipate' the next segment when flying a procedure.
At the time, they were offering a very attractive trade-in deal for
430s, which I suppose won't help you much. :-)

Charlie,
I am definitely considering the Avidyne IFD 440. I have a friend with one
in his RV10 and he really likes it.
I am also considering the new Garmin GPS 175 and then add a second comm
radio and call it done. (I already have a VOR/ILS/GS nav radio.)

Hello,
I am about to cut my antenna to final length and want to confirm:
a: if there is an optimal antenna length and
b: if there is a minimum distance between radio and antenna.
The radio is a MGL V16 remote mount
I have 2 possible antenna position and want to test both, at the moment one
is +/- 2 feet from the radio and the other +/- 8ft
Thanks
