Peskies / Re: 6962 USB 0413 UTC 22 Apr 2017
« on: April 24, 2017, 0432 UTC »
These guys are back again at 0430 UTC on 6962 kHz USB.  At least two stations talking (pretty sure its Portuguese).

2432
6.930 MHz LSB 6930 kHz LSB fishing fleets pescadores peskies 6930 LSB

These guys have been chatting for hours and hours.  It's now 0430 UTC and I first noticed them around 0000 UTC.  Portuguese, likely fishing fleets with stations talking over each other and single operators talking nonstop for 5-10 minutes at once.  Even though the band is mostly quiet (but still full of static crashes, etc) and the Spanish-speaking nets on 6900 kHz LSB and 6905 kHz LSB are long gone...even 6925 kHz LSB is quiet...this frequency remains very busy.

Very weak chatter heard, possibly Portuguese. 

2434
With some minor QRM from Unknown Name Radio Network on 6880 kHz AM.  Spanish language chatter 6.875 MHz LSB mode. 

Two OMs talking with noisy band conditions.  SIO 222 at best.  Still chatting away at 0425 UTC.

Special Ops using SELCAL?  Interesting. 

They are in the fixed/mobile band where mysteries abound...and if you're not finding the frequency on any lists online, chances are its military.  Not sure why they're using English though? 

2436
Likely an NGO or mission-based organization (this fits in with them operating in the "fixed/mobile" band) - interesting that they're using the same frequency for marine transmissions as well.  Chances are they have all the radios in their network programmed with the same set of frequencies (which likely makes everything easier for everybody involved - especially if they're not radio-savvy and/or don't really care about ITU band allocations).

In addition to 6707 USB, put a note to monitor 6900 USB from 2200-0400 UTC.   I just made a very long log of a net heard on 6900 LSB [see here: https://www.hfunderground.com/board/index.php/topic,34426.0.html] (I speak Spanish - and the stations are Spanish-speakers - but several of them stated they were transmitting from Central America and California, which means there's a possibility if you hearing them).  If you don't speak Spanish it's all good - I'm just interested to see if you can hear them.

Around what time(s) did/do you hear the 8076 kHz USB traffic?  I bet they have a 4 MHz frequency for nighttime check-ins.  It seems like most NGO, military and "fixed/mobile" user has a "day frequency" and a "night frequency" and going by the fact that they're using 8 MHz leads me to believe they should also have a lower frequency for nighttime operations...well, nighttime in your hemisphere.   ;D


2437
Similar to traffic heard on 6900 LSB, 6950 USB, and several other frequencies.

Signal reports and general chatter.  OM complimenting other operator for a very "rich" signal (literal translation).  Enrique, Carlos in Matamoros, Semprano in Tejas (Texas), Julio and other stations talking.  Likely same group heard on 6900 kHz LSB.  Similar "net-like" traffic net QSO roundtable ragchew fashion

---------------

At 0327 UTC, I tuned from 6900 LSB back up to 6905 LSB and started listing to this net:

Very similar format to net on primary frequency (6900 LSB)

43 meters, roughly defined as 6765 kHz to 7000 kHz, or 6.765 MHz to 7.000 MHz is an interesting piece of frequency spectrum.  In addition to military and government users, these frequencies are home to various types of "pirate" radio activity.  Some of it is pirate broadcasting, and some of it is "bootleg" two-way radio communications chatter, often in Spanish or Portuguese.  Today I'm focusing on the Spanish voices heard in this area, specifically on 6900 kHz, or 6.900 MHz, LSB mode.  My theory is that these operators are not actually fishermen (Spanish for "fishermen" is pescadores, which is where the popular SWL and shortwave pirate listener term "peskies" or "peskys" comes from).  While the Spanish language traffic on 6900 LSB and other frequencies may indeed be an annoyance, chances are they're land-based transmitters operating in a "freeband" manner similar to the way freeband 11 meters is done. 

6900 kHz LSB - 6.900 MHz LSB is one of the busier "peskie" frequencies on 43 meters.  The indications are, however, that the operators heard on 6900 (and nearby frequencies, especially 6905 LSB and 6895 LSB) are actually "freebanders" or "outbanders" radio operators, both unlicensed and those who hold radio licenses (probably ham licenses) but prefer to operate out of band, that are operating from land-based stations.  Below is an extensive analysis of one of their evening nets on 6900 kHz LSB.  Most of what I say about these guys applies to traffic heard in USB mode as well.  Often I'll hear 6900 USB active at the same time as 6900 LSB.  Since they're using modified amateur radio equipment, its simply a question of flipping the mode switch, I have a feeling this is done as a way to find another clear channel / frequency.

Disclaimer before you read this whole thing:  I know I've made a lot of posts about these guys, but this is one of the first times I've actually sat down and listened to their chatter for longer than 5-10 minutes.  My Spanish is a "conversational level", that is, I have ~2 years university-level Spanish language study plus extensive real-life practice speaking and writing it and am familiar with the terms used in two-way radio by Spanish speakers.  I don't speak it fluently, but I understand enough to understand what is being said and carry on a conversation with a native speaker without trouble.  On to the logs...

------------------


Strong stations chatting on 6900 kHz LSB.  Station taking check-ins for Jalisco, Matamoros, Texas, "el centro de Mexico", California, Costa Rica, Puerto Rico, etc.  Stations exchanging signal reports and talking about equipment.  Long-winded ragchew-like chatter.  Extended QSO about 11 meter band conditions earlier today, about "Carlos de Matamoros", conditions on 15 meter band (likely indicating that these stations are in fact licensed ham operators - or they're operating around 15 meters illegally as well).  Changed to political banter, talking about Facebook, and other long-winded "ragchew" like talk.  Several references to Matamoros, cities in Texas, Mexico City (Federal District), Costa Rica, and other places in Latin America.

New stations checking into net following similar procedures.  "Hola!" "CQ 43 metros" "estas llamando" (Hello CQ 43 meters! I am calling!")  followed by discussion about transceiver (un Alinco!, "tiene un yagi de tres elementos" ["I'm running an Alinco radio with a three element Yagi antenna"] etc) and antenna equipment and signal reports.  Once a new station is introduced into net, other stations give him signal reports, and he is entered into the rotation.  Several instances of stations calling "HOLA!" over each other, but generally more civilized than Portuguese-speaking traffic heard on 6925 LSB, 6919 LSB, etc. Specifically calling net control stations "Carlos en Matamoros" or "Juan en Tejas" which means Carlos (or Juan?) is possibly net control...Juan likely secondary or backup net control station.  Carlos (I think) mentioned this as "the frequency of North America" which backs up my theory that 6900 LSB is the "primary" 43 meter freebander frequency (for Spanish speakers anyway).

At 0256 UTC, mention of interference from boats (likely a reference to the "real" pescadores).  Radio check 1, 2, 3, 4...followed by "Echo Mike Sierra" (possibly a radio club identifier).  0304, more QRM from another net on frequency (stations in California).   

0308 UTC - Carlos requested a new station identify his name, his location, and his equipment.  Repeated back name "Martin" but could not hear location due to QRM.  0309 UTC, Carlos introduces Martin to other stations on frequency.  Then all hell broke loose (5-6 stations all replied to Martin at once).  0310-0311 UTC, Martin thanked stations for the good wishes and made several comments about the quality DX contacts he made earlier today on 11 meters. 

0313-0314 UTC - Juan called Carlos back about Javier, made some comment about Costa Rica.  Around this time, 6905 kHz LSB became active again.  Possible stations moved from 6900 LSB up to 6905 LSB due to heavy use of 6900 LSB. 

0316-0317 UTC - Two QSOs going at once.  Carlos working another, much weaker station while an UNID station talked over Carlos.  Carlos repeated request to "change" (meaning "change your frequency" or a request to QSY due to QRM).

0318-0319 UTC - new station on frequency asking for signal reports.  Net control answered and requested location information, etc.  New station calling from Costa Rica with a Yaesu, then requested if Carlos could hear him in Matamoros....followed by silence and new station saying "negativo" (meaning negative contact with Carlos in Matamoros).  New station then called Juan, who replied with signal report.  New station requested "repeat" (likely so other stations, or at least Carlos, could hear).   Very professional net control/traffic handling procedures going on at this point.

0321 UTC - Comments made about FT-757GX HF radio and another piece of equipment that I couldn't identify (read: translate).  Long winded chatter about equipment/antennas, at 0322, another station called CQ over this.  Chatter about 11 meter equipment "Superstar 3900" and comments about the excellent performance of the Yaesu FT-757 radio on 11 meters and 43 meters as well as his Superstar 11 meter radio. 

0323 UTC - station IDed as "Jalisco" answered by net control (not sure which one) who requested "more information" (net control severely fading at this point).  Clarification about where Jalisco is, more chatter [then heavy QRM].  At 0325 UTC, station said hello to Javier, mentioned something about his cellular phone, then more unreadable chatter.

0326 UTC - "El Centro de Mexico" and "Jalisco" signal reports, mention of Manuel and propagation conditions. 

0328 UTC - switching back and forth between 6900 LSB and 6905 LSB.  0328 UTC - very strong station came on and said "GOOD CONDITIONS, GOOD EVENING!" followed by reply by a half dozen stations (reminded me of a HF ham band pileup).  0329, more signal reports (likely a new station checking in to net).  Station identified as being in Costa Rica and complimented stations on frequency on good signals and mentioned hearing Mexico, California, general chatter about "good people on frequency".

0331 UTC - another strong station came on and said "hey what's up frequency 6900?!", followed by more stations checking in.  Band must be going long as I'm having trouble copying stations that were earlier SIO 444/SIO 555. 

0333 UTC - Much weaker station now talking to another [unheard] station.  Strong net control stations have either disappeared, QSYed or the band has gone long enough that I can no longer hear them. 
 
0336 UTC - After several minutes of silence, a station from Costa Rica called CQ and did the usual "good evening everyone" greetings but was not replied to (or at least I couldn't hear anybody reply to him).  Either the band has gone very long, everybody has gone QRT and/or they've QSYed up to 6905 LSB (the alternate frequency).

See also the thread regarding Spanish language chatter on 6905 kHz LSB.  Seems like the same group of stations. 

2439
8076 kHz falls outside the 8195 kHz - 8815 kHz 8 MHz HF marine SSB band (shared 8MHz band frequencies with fixed and mobile service start at 8101 kHz and go up to 8191 kHz in 3 kHz steps...8101 kHz, 8104 kHz, 8107 kHz, etc.  The 8101-8191 kHz channels are simplex only.  Duplex channeling starts with ITU channel 801 at 8195 (ship TX)/8719 (shore TX) and goes up to 8288 kHz/8812 kHz. 

7300 kHz to 8195 kHz is another "fixed and mobile" band (that is, everything and anything) so the traffic you were hearing wasn't in the legal 8 MHz HF maritime allocation.  Sounded official though, could have been anything else (or a yacht club operating out of band - I have logged several yacht nets in the 4000-4063 kHz range, although this is a fixed/mobile band it is legally shared with marine HF per ITU regulations. 

Seems to me like you've found another out-of-band marine user :D

Pink Floyd - Several Species of Small Furry Animals Gathered Together In a Cave and Grooving with a Pict with lots of QRM from 6900 kHz LSB, 6900 kHz USB and 6905 kHz LSB.

Sounds like several stations at once - or one station playing several audio tracks at once.  Either an attempt at jamming the pescadores on 6900 LSB, 6900 USB and 6905 LSB or two stations on 6900 kHz AM on top of each other.  Not sure.  At 0227 UTC, it's clear that there's one station on 6900 AM playing music, and several strong stations on 6900 LSB mixing in on top of the 6900 AM station's modulation, making it sound like multiple AM stations.  S9 level signals for both 6900 AM and 6900 LSB. 

Interesting frequency choice, whoever you are - but thanks for the show!   ;D

6970 kHz LSB - Portuguese
6995 kHz LSB - Portuguese

Unknown Name Radio Network 6900 kHz AM getting mauled by SSB two way voice comms traffic (peskies) Spanish language 6900 LSB and 6905 LSB both getting stronger at 0059 UTC making listening to 6900 kHz AM very difficult.

2443
6900 kHz AM - Spanish language traffic on 6900 LSB and 6905 LSB causing QRM
6912.5 kHz AM - Spanish language traffic on 6915 LSB and 6910 USB causing QRM

very busy band tonight

2444
Electronic dance music, S5-S7 signal with decent modulation and peskie QRM

0056 UTC - remix of "Pump Up The Jam" by Technotronic

Off suddenly at 0100 UTC.  Suffering from peskie QRM on 6910 kHz LSB

2445
Rap music 6900 kHz AM with very strong Spanish language two way traffic on 6900 LSB (and 6900 USB from time to time).
