you're an idiot, see I said it simpler that Avboog

I'm an idiot? Yeah.... better than switchbitch? Hmmm. Not sure but I am sure the terms are equally inappropriate.

You choose metro: Your incapacitated in the heat. 406 or 121.5? 20k resolution or 100meter? Over 60% of the earth or full earth coverage?

Let the idiot know please. I'm curious what such an accomplished, experienced aviatior such as yourself has to bring to the table in terms of an intelligent opinion.

From Wiki:
Traditional ELT, unregistered

The oldest, cheapest (US$ 139) beacons send an anonymous warble at 121.5 MHz. They can be detected by satellite over only 60% of the earth, require up to 6 hours for notification, locate within 20 km (search area of 1214 km²) and are anonymous. Coverage is partial because the satellite has to be in view of both the beacon and a ground station at the same time - the satellites do not store and forward the beacon's position. Coverage in polar and south-hemisphere areas is poor. The frequency is the standard aviation emergency frequency, and there is interference from other electronic and electrical systems, so false alarms are common. To reduce false alarms, a beacon is confirmed by a second satellite pass, which can easily slows confirmation of a 'case' of distress to up to about 4 hours (although in rare circumstances the satellites could be position such that immediate detection becomes possible.) Also, the beacons can't be located as well because their frequency is only accurate to 50 parts per million, and they send only 75-100 milliwatts of power.

With a 121.5 MHz beacon, only one alert out of every 50 alerts is a genuine distress situation. This has a significant effect on the resources of search and rescue (SAR) services. With 406 MHz beacons, false alerts have been considerably reduced (about one alert in 17 is genuine) and when properly registered can normally be resolved with a telephone call to the beacon owner using the encoded beacon identification. Consequently, real alerts can receive the attention they deserve.
When a 406 MHz beacon signal is received, SAR authorities can retrieve information from a registration database. This includes beacon owner contact information, emergency contact information, and vessel/aircraft identifying characteristics. Having this information allows SAR services to respond appropriately. Make sure your 406 MHz beacon is properly and accurately registered!
 
You're too busy trying to be smart...too busy to note that nobody here has suggested that 406 MHz isn't an improvement. Nobody has decried it or put it down...your argueing an arguement that doesn't exist...one you've made up.

What you did do was make a stupid, erroneous statement that ELT's operating on 121.5 MHz are worthless. They're not.
 
The new radios don't have a squelch override so need a strong signal to receive it.

I could obviously be wrong, actually I'm a little overdue for it, but what new radios don't have squelch?

This is what I wrote word for word:

Compared to a 406 beacon with a GPS a 121.5 ELT is worthless...

Anyhow I seems your missing the first 7 words of this phrase. "Compared to" sort of sticks out in my mind as important.

I'll go back to "trying" to be smart now.

I was refering to the watch ELT (how powerful can the transmitter be inside of a watch with no antenna!?) but to be fair I didn't make myself perfectly clear. Of course we all need impressive watches that can save our lives.


com·pare –verb (used with object) 1.to examine (two or more objects, ideas, people, etc.) in order to note similarities and differences: to compare two pieces of cloth; to compare the governments of two nations. 2.to consider or describe as similar; liken: Shall I compare thee to a summer's day? 3.Grammar. to form or display the degrees of comparison of (an adjective or adverb). –verb (used without object) 4.to be worthy of comparison; be held equal: Dekker's plays cannot compare with Shakespeare's. 5.to appear in a similar standing: His recital certainly compares with the one he gave last year. 6.to differ in quality or accomplishment as specified: Their development compares poorly with that of neighbor nations. 7.to vie; rival. 8.to make a comparison: The only way we can say which product is better is to compare. –noun 9.comparison: Her beauty is beyond compare. —Idiom 10.compare notes. note (def. 32).
 
Weirdly enough, I think those Breitlings actually have some sort of pull-out (like a wire or something) antenna to help the transmitting power. Still gimmicky though...I can't imagine that an ELT in any Breitling has helped someone in a genuine emergency situation, but I could be wrong.

:cool:
 
I was blessed from birth being able to make the exact same sound as an ELT, and if I clench a metal fork in my teeth it transmits the ELT sound I am able to make on 121.500.

Kind of like the raptor voice box the dude blows in on Jurassic Park III.
 
Avweb.com has some interesting links that you can use to "help" find Mr. Fossett. Seems they are using spy satellites to take pix of the area. You can then look at the images to see if you can spot anything of potential interest. You can then mark the spot, and someone with the search effort will look over what you've marked. Most interesting, as Spock would say.

I could obviously be wrong, actually I'm a little overdue for it, but what new radios don't have squelch? by svcta
I believe bubbers44 was speaking of a way to turn off the squelch, like some old radios that had a very small button to push, new radios in Boeing's have automatic squelch, no feature to adjust or turn off.
 
SAO, Yes we used the manual squelch to let even the most marginal signals to come through at Aircal talking to company in fringe areas. We always heard ELT's when United couldn't because they had the newer auto squelch airplanes. Steve would probably have been found if that "Do you copy" message was from him and airliners could still use manual squelch. Also the Brazil midair might have not happened if they had the ability to hear weak transmissions. Over the Carribean I have wished for manual squelch many times having to get relays from closer in flights. GPS precision and auto squelch had a lot to do with the results of the Brazil midair. Legacy almost heard them but they were exactly on course. Sometimes progress makes the situation worse.

That's why there is SLOP, lost comm procedures, and TCAS.

Hopefully nobody will be flying right down the airway in non-radar with no comms.

Unfortunately TCAS went inop that day, lost comm procedures were not ignored and SLOP is not a standard procedure so few pilots use it.

406 with Built In GPS and Reg Here http://www.beaconregistration.noaa.gov

I know my Beacon ID is Reg'd Lots of phone Numbers listed.

I think if you are in aviation, mountian climbing, Hiking, Etc a 406 EPIRB should be required or you pay sars fees.....If they have to come find you!

The Climbers on MT Hood last winter did not have one not even a 121.5 and rentals were available on the mountain either one would have saved their Life and tax payers lots of money.

I know 3 people saved by elt & epirbs 1 by 121.5 other 2 by 406.....

I understood the point, I just used an abbreviated term to ask the question, so my fault.

I didn't know, and just confirmed it, that Boeing radios(or the radios in Boeings) don't have a manual squelch function. I'm told that it works very well, but it seems like I open the squelch on a radio a lot to get an ATIS a little early, or listen for an ELT(at center's request) or something. I can't adjust it from the RTUs that I've used, but it can at least be turned off.

Thanks for the info! Learn something new every day......
 
Any word on Mr. Fossett? With the search going on this long, it really makes you wonder what's going on.
