I'm running one Dynon comm and one Avidyne, and I can't tell any difference at all in transmit/receive range between the two. I've never had any trouble reaching out 60+ miles.
Depends on which one is suffering the problem. If ATC is saying they cannot see your ADSB, then your transponder is the problem. If you cannot receive ADSB IN (traffic and weather) then it's your ADSB receiver antenna.
If you have a good antenna and coax, that extra wattage really is meaningless. If you need that extra wattage to gain acceptable performance, antenna and coax is a much easier fix than a new radio.
Dynon will be at Sun and Fun next week with a display, drop by and ask.
Two different issues here - ATC saying your ADSB is having an issue means you need to look at your transponder, the issue is there. They are seeing the "output" of your airplane from your transponder carrying your ADSB information out to the world.
Traffic cutting out is on the "inbound" side...
If it's sheared, it may well move with the stick until/unless force is applied to the control surfaces, resulting in torque at the shaft which the shear screw normally resists. Try turning on the autopilot (sitting on the ground) in "level" mode and try to move the control surfaces yourself - or...
Emphasized portion there - not an ATC clearance, but an operations standard, and apparently only applicable on oceanic tracks.
Makes good sense in that scenario I guess, the aircraft is off-radar anyway, more freedom to "operate as appropriate".
Agreed on all points. I'm running an Avidyne 440 for IFR, but the Dynon approach plates from Seattle Avionics with georeferenced positioning would allow in a pinch to fly the lateral limits, and just fly step-down altitudes. Wouldn't be pretty but it would work.
This is a slippery slope, providing the ability to shoot an approach without a certified receiver. I get it that people want it, and the device is capable of doing it, but I also see this is ripe for abuse. Barring a ramp check, which is pretty uncommon, nothing stops a pilot from flying...
Caution on the cable splitter for the glideslope - the device you want to use there is actually a DIPLEXER, not a generic splitter. It's a band-pass filter combined with a splitter that increases the signal-to-noise ratio of each output stream for better long-range reception.
You can load the charts from a USB to display on the HDX, with your aircraft geo-referenced over the top of the chart and "fly" the airplane along the charted path by using the autopilot and TRK function, but there is not a way to automatically load the waypoints of an approach into the HDX and...
