    Directional gyro

    Carry out the ground and in-flight compass calibration. It's in the installation manual, and quite easy.

    Transponder & ADSB antenna location?

    Should be fine under the fibreglass body in the aft fuselage, Glassairs do a similar thing.. You will need a ground plane of about 100mm x 100mm, make it from a sheet of thin aluminium. Transponder and ADSB antennas need to be at least 2 ft apart, further if you can. Antennas obviously need to...

    Supply Chain Update: How the current crisis is affecting Dynon

    Yes, through the Australian distributer. They got them in for me (I think they had 4 coming)

    Frequency specific background noise on Dynon com radio.

    Amazingly, I've seen this happen with a USB charge port, like the one you would put in to charge your iPad or phone. Pulled the wire off it, and the problem went away. Yes, it was frequency specific as well. Might be prudent to try depowering everything else one by one to see if it is...

    HDX Audio Alerts - Only Very Faint

    Did you upgrade to HDX from the Dynon classic screens or something else? Go into the setup menus, and check the audio output, make sure it's not just set way too low SETUP MENU > SYSTEM SETUP > AUDIO SETUP. There's also a test mode in that menu to help you with fault finding. There are three...

    HDX Audio Alerts - Only Very Faint

    Has this only just started happening, or has it been like it from the start?

    D10A discontinued?

    It is, and it is. Even has autotrim 👌

    D10A discontinued?

    Ah OK, I misunderstood that you wanted a front removal. I agree it's a strange way to mount instruments. A clamp mount that can be loosened from the front would be a good design idea, like the old Sperry HSI's in King-Airs

    D10A discontinued?

    You assemble the D10A onto the flush mount first. You see the outer groups of 3 holes? they are to install nut plates / anchor nuts into, and you attach the flush mount to the panel with screws from the front of the panel. Yes, you have to physically hold the unit up to the back of the panel...

    D10A discontinued?

    You install it in the $20 flush mount bracket, then you can remove it from the front no worries.

    HDX Audio Alerts - Only Very Faint

    The audio from your Skyview goes into the ACM module via the EFIS PFD connector, comes out on the Audio Panel DB25 connector (labelled "audio panel"), and then to your PDA360 unswitched audio #1. Unswitched audio #2 is from your IFD, are the NAV alert sounds also muted? The reason you still get...

    New Install - Comm and Intercom issue

    Good stuff mate! What are you building?

    New Install - Comm and Intercom issue

    Yeah, putting the mic output from the IC straight into the audio input (your headset) won't work due to the impedance mismatch between the microphone, and the headset speakers. Try the mic audio from the jack straight into the radio input pin 23, and listen to your normal headset output as...

    New Install - Comm and Intercom issue

    Since your wiring is all good, it's either going to be the intercom isn't switching audio through to the radio when PTT is active, or the radio isn't outputting sidetone. You could make up a small harness from your mic jack ring terminal (mic hi), straight to the radio input pin 23, this would...

    New Install - Comm and Intercom issue

    Yeah, you should hear yourself on transmit (sidetone). Push it outside if you can and try for a radio check to another aircraft if possible, or borrow a handheld. Yes, it's a simple connection, check your mic hi and lo twisted pair aren't reversed at the radio (23 and 9), and you have...

    New Install - Comm and Intercom issue

    Sidetone generally comes out of the radio on the audio lines. If you break squelch, can you hear the radio? If you can, then I would suspect that microphone input to the radio from the intercom. Are you sure the radio is transmitting voice?

    Rpm jumping about and reading very high on take off

    I had this initially on a C210 install. I had installed the 30Kohm resistors where I picked up the RPM from the P-Leads, but I had to install another two to stop the RPM from jumping around. It was especially bad at full throttle. No more problems after that. The install manual details it...

    Rotax 912 ULS/HDX EMS jumpy oil pressure & high fuel pressure

    I don't have Rotax diagrams, but for a Lycoming, the oil pressure, fuel pressure and manifold pressure all share the same 5 volt source and ground from the EMS, pins 18 and 17 of the sensor harness. Might be the same in your installation.
