4885 khz USB bizarre Spanish voice scramble
« on: December 07, 2012, 0057 UTC »
Spanish voice 12:44UTC YL now OM: "romero, romero (unintelligible) primero" again and again- preceded by some odd voice scrambler sounded like a speeded up record. OM again calling "romero, romero (something something) primero"

pardon me if I am posting in wrong forum area- I'm not that familiar with the band plans I had to google it and still not so sure about them. Seems odd to hear what sounded like amateur on this frequency. Can someone clarify- or at least point to a site where I can find exact allocations for certain frequencies? I have the ARRL color band plan, seems like this frequency is not a "ham" one. If I am mistaken please reply or mod relocate this into the right forum. Thanks.

That's not in a ham band. Very likely a spy numbers or utility station.

The ham bands (in the USA) are:
1800-2000 kHz
3500-4000 kHz
5332, 5348, 5358.5, 5373, 5405 kHz (five frequencies in the 60-meter band)
7000-7300 kHz
10100-10150 kHz
14000-14350 kHz
18068-18168 kHz
21000-21450 kHz
24890-24990 kHz
28000-29700 kHz

Sometimes you will hear anomalies in the ham bands that are not amateur signals. There are also segments of the ham bands used for various digital modes, so if you hear strange signals around e.g. 14070 you're probably hearing PSK31, Hellschreiber, MFSK16, Olivia, etc.

Outside the ham bands there are always strange and curious things to hear!
East Central Illinois
TS-850S, 40 meter full-wave loop, various dipoles

Thank you I thought so. I am a relative noob, so I doubt some of my catches as I am merely a casual listener not a ham. I appreciate your info

Hello. The activity you hear on 4885 is from the Mexican Navy

yes thank you solarix you probably have several audio files on your site as well. It would be wise to check your site first before asking... but I'm not so wise sometimes//
