Distress Calling

[ScanPEI]

Anyone know the frequency or frequencies for distress calling? All I could find was 121.5.

Any input would be appreciated!

That's it. 243.0 for military.

Also 243.000am military UHF guard.

156.8 MHz Ch.16 for marine.

Here they are;

121.5000mhz. am,243.000mhz. am/fm,406.000mhz. fm,156.8000mhz. fm

There are a few others,but not widely used.

Hey N9ZAS, check this out: Distress radiobeacon - Wikipedia, the free encyclopedia Scroll down & click on: "406.0 MHz beacon performance review", then scroll down & click on: "background & supporting information" then scroll down & click on: "manufacturers sales material for beacons tested" & read the operating frequencies on some of the epirbs. 406.0 MHz 406.025 MHz & 406.028 MHz, I then Googled "What are the new epirb frequencies on" I couldn't transfer the two FCC websites so click on: "{doc} Wireless Telecommunications Bureau" & the site directly below it: "{pdf} Federal Communications Commission DA-OO 2845 Before" & they both confirm this.It appears that there never was a 406.0 Mhz epirb but a 406.025 MHz one & now they are transitioning to 406.028 MHz, So much for consistincy.

Right! I guess we better hope we're never in distress...we might never be found!

As I recall, that is 2182 kHz and it is not monitored nearly as much as it once was.

JOAN7XXX is not entirely wrong, I have on occasion heard emergency (Not life threatening) traffic on non-distress hf marine frequencies & it could be so in his case or maybe it was a typo. This type of communication may not be as common as it is on aviation frequencies as if an IFE occurs on an aircraft, they don't switch to 121.5 MHz as many people are led to believe, the pilot just announces his problem to whatever ground controller he is in contact with on that particular frequency. Until 9/11 I never ever heard any distress call on 121.5 MHz The only traffic I hear now are very infrequent "A.C.C. air combat patrols" warning small aircraft who have strayed off course. The frequency 2182 KHz is being phased out by the U.S.C.G. & being replaced by 2187.5 KHz however 2182 KHz is still alive & will be used for quite some time.
