Has anyone had any problems with their ACK E-04 ELT going off when the avionics is turned on? RV14a getting close to maiden flight, however the ELT unit does not like all our radios being turned on. We disconnected the remote cable and the GPS info cable, leaving the ACK E-04 ELT unit with only the coax, static suppression device, and its antenna connected, yet the ACK E-04 falsely triggers. The coax cable does not run with any other cables and has good integrity with no shorts to ground. Coax does end up going to ground at the antenna mount (by design). The closest antenna is on the bottom side about 4 feet forward of the ACK E-04 ELT. We disconnected the antenna from the coax, unit still false trips. It appears the energy from our radios is getting thru the plastic casing of the ACK E-04 ELT.
We can keep this from happening if we wrap the ACK E-04 ELT in aluminum foil. We are using the heavy-duty Reynolds wrap, aviation grade (2 layers). I would prefer a more professional solution than Reynold’s wrap. We are using the Dynon AFS AF-5600 in a dual EFIS configuration with SKYVIEW SV-COM-X25/H, Skyview SV-ADSB-472, Skyview SV-XPNDR-261, Avidyne IFD-440. We don’t even have to transmit on com to have the ELT false trip, which likely means this is triggering from the ADSB out.
