Looks like Casey Curtis' Catalina, which I tried to buy in 2011 with a bucket of cash and my Piper Clipper.  That's a beautiful Catalina, maybe the best ever. Glad to see someone is enjoying it in lake country.

Here's a KT76A in Skyraider II panel. That's a narrower panel since seating is tandem rather than side by side.  You can lay out your panel any way you like. My KT76A tray is bolted to the panel face by two screws on each side, and is supported in the rear by a stiff rubber bungee around the top frame attaching to each rear corner.

Hi DH, yes, I use those lift rings to hoist the SRII up to the rafters in my hanger, which gives me room for one more toy, and will come in handy for switching out tires and floats.  I'm designing float rigging that will have 4 fixed attach points mating to the axle and main strut float fitting so I'll be able to just pull off the tires and set it down and attach with 2 pins and 2 axle saddle caps. I'm attracted to the idea of flying off of water, and I've read just enough Jimmy Buffet to be enamored of the Widgeon--lucky you.

Yep, I recall. I still intend to make it to Madelia after I get my Cozy out of Phase 1.

I have a KT-76A mode C in my SkyRaider II and in my Cozy, and I fly out of an airport near my home underlying Class B, so I'll need to get compliant in both for 2020.I've had my eye on the NavWorx-EXP unit as the lowest entry cost, but I'm glad I didn't pull the trigger since they are now battling the FAA and could crater. I'm now waiting to see how things shape up for the uAvionix Echo ATU 20, which was exhibited at Oshkosh last summer. http://www.uavionix.com/products/echo-atu-20/ This is from a Palo Alto based company primarily going after ADS-B for the UAV / Drone market which stands to have greater volumes and cost efficiencies. It is a very small and light unit, and they expect to price this version for the experimental aircraft market at around $1200 (I could see that going up if NavWorx craters, but hopefully competitors will proliferate to keep prices in check).  It has built in WAAS GPS and receives on both 1090 and 978, and transmits on UAT 978 MHz, so it doesn't need the Mode C coax coupler that the NavWorx required; it picks up your (1090) Mode C from its single dipole (ADSB needs to use the same squawk code as your Mode C transmitter so must monitor and duplicate).  It has only WIFI for delivering ADSB-In Wx/traffic for tablet display unlike the serial port NavWorx provides but I can probably accommodate that.  uAvionix is still working towards FAA approval for this unit. They have recently received approval for similar units from the UK Civil Aviation Authority and expect FAA approval in 2017. Don't jump too soon if you don't have to.
