    Default Hey all. Appreciate some input on a strange frequency

    Hi everybody, I'm pretty new to the field and I came across a strange frequency. https://soundcloud.com/user-13-87780...on-freq-454080


    While scanning my Ham Radio I came across this strange transmission on 454.080 in NYC. This frequency transmits randomly but frequently. *I don't really know what to make of this. *Is it an emergency station that people use only during national disasters? *Do they use the tones to make sure the station is functioning properly? *If anybody knows I'd appreciate some help. Thanks!

    It sounds like a pager, maybe 9600 Baud...

    Hey, thanks for your reply. I'm pretty new to Ham Radios, is this something that people come across frequently?

    Well, the 70cm Amateur band ends at 440MHz (in the U.K at least) so we don't really have much business "up there".
    Saying that, they do cause some problems for us and we would usually hunt around adjacent frequencies for the culprits.

    There is an older pager system down around 153MHz, which gives us 2m "bleedover".

    Have a look at this video, it should give you some idea of how the system works...

    You could try some Pager Decoding Software from here http://www.discriminator.nl/pdw/index-en.html that might decode it, and then send you off down a different track of listening.
    I'm leaving now to go find myself....if I arrive before I get back, please ask me to wait!

    In the US, 70 CM goes all the way up to 450mhz.

    454 is a commercial band. Probably some taxi paging service / dispatch.

    I don't think that software supports Com5 ports. It does't work for me. It looks like an interesting bit of software though.
