just flew from WMC to SVE with one radio tuned to 121.5 and looking for a wreckage . . . . nothing . . .
anybody have any news?
This is a good time to remind everyone that when monitoring 121.5 for an ELT be SURE to turn your squelch OFF!
Many radios will consider even a full strength ELT signal to be static and squelch it out. This includes the radios in our 1900s (we have the original style Collins units found in many King Airs). I've turned it on and off a few times while recieving strong ELT signals to verify this. With squelch on you may fly directly by an ELT and never know it. At best you may miss out on weaker signals.
Also noteworthy is that there can be a "dead zone" for an ELT just like a VOR's zone of confusion. If you pass directly overhead an ELT the signal may dissapear. An immediate drop off and then return of signal can signify you have passed over the transmitting device.
If monitoring for ELT signals, try to note your position as soon as you hear any signal (fade in) and then when you lose the signal (fade out). This is mostly useful when triangulating an ELT position, but can give SAR personel a better starting point (gives a better reference on where you would have received your strongest signal at). There are more procedures regarding ELTs and monitoring you can find in the AIM, but I believe this covers the important aspects.
Unfortunately, at this point the ELT batteries will have ran out, if the ELT was actually operating in the first place.
