Flying on a North-Easterly heading the PAI-700 panel mount compass informed me I was heading West. This is a new problem and the photo taken some years ago shows the relative positions of the instruments with reasonable agreement between the panel mount compass and the Dynon EFIS. Taxiing around a circle without the Dynon EFIS D100 in the panel gives good compass readings. With the EFIS in place the compass reading remains between South and West. I took the compass and EFIS to the compass manufacturer, Precision Aviation, where they confirmed that the compass is OK and the EFIS magnetization too strong for a mu-metal shield to help. The next photo below shows a compass correctly pointing North and the second shows it after rotating to point to the EFIS display, folded out from the box of electronics and sensors. The magnetization appears to be concentrated halfway up the left side of the display. Dynon Technical Support deny there is anything wrong and my eventual request to buy a replacement display went unanswered. This led to a google search for a demagnetizer that found many plausible devices for up to a few hundred dollars that's no doubt less than a new display. Can anyone advise if it's feasible to demagnetize a display screen and offer any tips, or ideas as to how the display became magnetized? I understand that a standalone magnetic compass isn't required if you have an remote electronic magnetometer but I appreciate the redundancy and the units did after all coexist harmoniously for some years. Thanks in advance!!

Copper tape can be used to create an antenna, the more of the antenna that is vertical the better the performance. A BNC connector can be soldered on to the foot, not sure how the ground plane would work, perhaps it needs to be a dipole? I haven't been very close to anyone who has used a tape antenna, but my impression was always that they required more maintenance, and often have worse performance, than installed antennas. How important is a reliable radio against saving weight? Peter, Thank you for your advice. Indeed the main point is having a reliable radio, so the antenna (Bob Archer) will be in the glass fiber fin, as originally intended.

(The compass on your iPhone (if that is what you have) is apparently not affected by a nearby magnet!). Did you move it around and rotate it to see if the apparent magnetism is localized at some point in the D100? Is it possible that you had a steel screw or nut to secure the unit in place? What would happen if you removed both units from the panel and positioned them in various arrangements in magnetically benign area? Just thinking out loud!
