Peskies? Military? Other? 6920 USB 0106 UTC 5 Oct 2018
« on: October 05, 2018, 1200 UTC »
I noticed a few transmissions like this around this time, starting with alternating beeping tones, then into a SS OM, here is a recording of one transmission: http://radiohobbyist.org/blog/mypics/6920usb-0106z-5Oct2018.mp3

My Spanish is rusty, I think I heard some numbers and maybe a mention of a frequency?

Sounds like military or other land mobile traffic out of Latin America - its pretty noisy but I distinctly heard "frequency" and several series of numbers mentioned

EDIT: listened to it a couple more times

almost sounds like an alert or emergency type "broadcast" - the tones at the beginning aren't like anything I've heard the freebanders or peskies use before...."15" "frequency" "45", "75" and a possible mention of "la plata" (literally "silver" but a better translation is "money" or "cash" - could have been another similar sounding term though, perhaps "la playa" [the beach] or "la plaza" the plaza which is a term used by Mexican drug cartels to indicate areas of operation or influence of a particular cartel...) - heard "45" a couple times, could be a numerical ID for a station or a frequency/channel.  Difficult to make out what else is being said.  This could be related to the tropical storm developing in the Gulf of Mexico

Thanks for your insights, R4002.

I don't recall hearing this before, not recently anyway. It stood out on the SDR recording vs random peskies due to the tones.

The tones remind of me of a marine weather broadcast or something like that...or could be part of a land-based fixed/mobile network.  Maybe oil rigs in the Gulf?  I think I recall 6920 kHz USB being one of the frequencies they've been heard on in the past.  Some sort of alerting system to get an operator's attention I would guess, or maybe some obscure selective calling system.

This doesn't have the characteristics of freebanders or the rural radiotelephone link systems that are often heard closer to 6700-6800 kHz which leads me to be believe its a more traditional "professional" HF radio network that you've stumbled upon.  It could be net control "waking up" a net on the frequency or a reminder to switch to "frequency 15" at a certain time....something like that.  So much of what's said is impossible to make out for sure though (and my Spanish is nowhere near perfect, especially if slang terms are used).

Yet another mysterious HF radio transmission out of Latin America :D

There's a tremendous number of them. While other parts of the world are cutting back on HF use, it seems to be constant if not growing there. Lots of things to listen to!

Their usage of 11 meters is insane too.  Mexican taxicabs with Superstar 3900 export radios and 600 watt amplifiers to talk to their dispatcher 10 miles away. Latin America and Oceania are both still heavy users of HF.  I imagine certain parts of Asia and Africa are too.

6920 USB is active again at 1221 UTC Oct 8th not sure if this is the same group heard on the 5th but it sounds like it could be.  Several mentions of two and three digit numbers....there are several other Spanish language QSOs going on in the 6765-7000 kHz range right now...

I noticed this again last night, around the same time, 0103 UTC on 6920 USB.  Hey - 7 days later. Is this a weekly net ???

Sounds like it could be!  We might have stumbled upon civil defense or another type of emergency service net (maybe the Latin American version of the FEMA SHARES network?)

Hopefully somebody can keep an ear on or near 6920 kHz USB tonight and see if this is indeed a weekly net...would be further proof of organized HF-SSB networks mixed in with the fishing fleets and land-based freebanders/outbanders.

It will be on my regular 43m SDR recording.

Heard again at 0057 UTC on 20 Oct 2018 on 6920 USB, weaker signal this time, but the warbling tones are distinctive.
