While tuning through the bands last night and this morning looking for freebanders, peskies, etc, I noticed 6739 USB is a lot busier than it has been in recent memory.  No doubt this has to do with the activity in the Mediterranean Sea.  Heard "Guidepost" and "Andrews" making long alphanumeric broadcasts, mostly with the prefix "All Stations All Stations" and the ominous "Skyking Skyking Do Not Answer"  After a several minute long string, heard "disregard this transmission, this is Guidepost out" followed by 5 or so seconds of silence and then another alphanumeric string. 

Strong Spanish language traffic has been going on and off for nearly an hour (started listening around 0500 UTC) on 6999 kHz USB.  Some CW QRM from 7002 kHz and 7002.5 kHz (possibly intentional QRM/hams jamming the voice traffic that's most definitely intruding on 40 meters). 

Interesting frequency choice.  I listed 6999 kHz USB in my previous logging thread that contains a bunch of frequencies but 6999 is, well, I suppose I shouldn't be surprised

Other / HF Marine Net 4149 kHz USB 0500+ UTC 10 April 2017

Several English-speaking stations talking to each other about boating, unemployment in Florida, crews from Cuba, working in Lake Charles, Louisiana, etc.  Callsigns are either numerical or simply the other stations' first name (Cicil, 7508, Janine, etc).  Talking trash about other boaters, crews etc ("any of y'all been sailing with Andrews lately?")  Several instances of stations talking over each other.  

I'm calling this a net but there's no net control station.  No actual callsigns heard after ~15 minutes of listening.  Very informal conversation, likely a regular net.  4149 kHz USB is one of the 4 MHz marine HF-SSB simplex frequencies, designated "channel 4B".  

Starting at 0400 UTC April 9th 2017

6 MHz marine band 6200 kHz to 6525 kHz
6 MHz aeronautical band 6525 kHz to 6765 kHz
6 MHz super fun do whatever you want pirate military government pescadore band aka "fixed and mobile" 6765 kHz to 7000 kHz

Only a couple of these in the legal HF marine bands.  WLO marine broadcast at 0700 UTC 6519 kHz USB shows that the Spanish traffic on 6521 USB wasn't on a one of the channelized marine frequencies (channels), 6200 kHz, 6203 kHz....6519 kHz, 6522 kHz, 6525 kHz [3 kHz steps].  6521 and 6524 kHz are 3 kHz away from each other but don't follow the ITU HF SSB marine channel plan.  I tried listening to 6519 kHz and the Spanish language traffic on 6521 was making it impossible.

Lots of stations using the aircraft frequencies


6412 kHz USB - Asian language, very busy after 0500 UTC

6838 kHz USB - Spanish, active after 0545-0555 UTC
6840 kHz USB - Spanish, active after 6838 went quiet
6876 kHz LSB - Unknown language
6885 kHz LSB - Spanish, active after 0440 UTC
6899 kHz LSB - Spanish, then QSYed back up to 6900 LSB
6900 kHz AM carrier  - Station tuning up, then switched to 6900 LSB and said "Hola! Hola! Hola!" several times S9+30 signal!
6900 kHz LSB - Spanish
6900 kHz USB - Spanish (strong)
6907.5 kHz USB - Spanish (I think) with extremely strong QRM from data signal on 6909 USB
6910 kHz LSB - Portuguese (QRMing 6907.5 USB and getting QRM from 6909 USB)
6919 kHz LSB - Portuguese
6923 kHz USB - Spanish - active after 0645 UTC
6930 kHz LSB - Portuguese (very strong and busy)
6930 kHz USB - Spanish
6940 kHz LSB - Portuguese (busy after 0500 UTC)
6950 kHz USB - Spanish, sporadic signal
6957 kHz USB - Portuguese
6966 kHz LSB - Portuguese, weak signals but readable
6985 kHz USB - Portuguese, followed by Spanish traffic at ~0430 UTC
6988 kHz USB - Spanish
6999 kHz USB - Spanish, active at 0530-0545 UTC and 0705-0710 UTC with [possibly intentional] QRM from CW on 7002 kHz.

More Spanish-speaking traffic popping up this afternoon.  Interesting frequency choice (appears to be closer to 6699.45 kHz USB), but 6699.5 USB is another easy to remember frequency to that checks.

Strong data carriers on 6700 and 6701.9 making listening to these guys very annoying.  Sounds similar to the traffic heard on 6905 LSB earlier.  Radio-related discussion, including one op whistling into their mic.

I imagine its a mixture of modern "modern" communications methods (such as the Internet, encrypted cellular/mobile devices, satphones, etc) and HF/VHF/UHF. 

I know drug runners (in the past) made extensive use of HF marine frequency bands (and the "traditional" freeband spectrum, that is, the areas above and below the regular ham bands) so I'm sure there's still some of that going on, especially in more remote areas where even a hopped up 10 meter export radio wouldn't be enough. 

When you think about the flood of open-banded Chinese VHF/UHF gear, its surprising that a lot of the comms you're talking about are for "local business" communications still.

Two OMs talking about antenna tuning, radios and various other "ham-like" QSO stuff "el antena tuner AT-180" [assuming they're making reference to the Icom AT-180] "un Yaesu" and other recognizable equipment names/model numbers. Long-winded discussion regarding antenna tuners. One station is considerably stronger than the other (peaking at S6 with good audio).  No names or callsigns heard so far (at 2023 UTC).

The rest of the 6700-7000 kHz region looks quiet right now (afternoon on US East Coast).  Checked a couple remote SDRs and they're showing the same - that is, the guys talking on 6905 LSB are the only stations on 43 meters right now.  

Appear to have gone QRT at 2032 UTC.

6900 USB and 6919 LSB seemed to be the most active stations last night (US East Coast night time anyway).

6750 USB was also very very active (I know I made another thread about this logging, mainly because I haven't heard "peskie" traffic on 6750 kHz before).

New frequency logged.  Two OMs chatting away on 6750 kHz USB.  I've logged traffic on 6755.5 USB, but not 6750 USB.  Frequency is clear at this time (0310 UTC).  Perhaps this is the "net" that was previously on 6755.5 USB (Trenton VOLMET is going strong on 6754 USB but this frequency is far enough away to avoid QRM). Stronger station is peaking at S9 and weaker station is considerably weaker (S2-S3).  Stations are Spanish speaking with Mexican accents.  No location information clues or names/callsigns heard in ~10 minutes of listening.  

Thanks for this video, KK7.  Crazy 30 kHz wide signal and local FM station level audio quality. 

Interesting frequency choice as well.

News broadcast relay talking about American airstrike on Syria with Donald Trump audio clips and pescadore QRM.  S4-S5 signal with some fading, sounds like a possible CNN relay?

Signal dropped significantly at 0245 UTC, but is still going at 0249 UTC

I like the idea of putting multiple frequencies on a single logging thread, Chris.

On nights like tonight where I look at a handful of different SDR waterfalls and I can confirm several of the frequencies you've listed have been active and are active right now.  

I'm assuming you're sticking to 6800-7000 kHz range since that's what you're listening to anyway (in regards to the SDR recording)

A quick look at the band (at 0200-0300 UTC April 7th) shows me the following active frequencies:

6750 USB - Spanish (very very strong - Mexican accents)
6780 USB - Portuguese (weak)
6845 LSB - Spanish
6868 LSB - Portuguese
6888 LSB - Portuguese - strong
6888.5 USB - Portuguese - weak
6900 LSB - Spanish - VERY strong
6900 USB - Spanish
6915 LSB - Portuguese
6919 LSB - Portuguese
6925 LSB - Portuguese
6960 LSB - weak, likely Portuguese

Very strong Trenton Military VOLMET transmission on 6754 USB making copy of the weaker two-way traffic on 6755.5 USB very difficult.  I'm 95% sure that its Portuguese but the weather forecast traffic 1.5 kHz down combined with storm static QRN makes making what these guys are saying out very frustrating.

They're using another "cute frequency" - like the operators I heard on 6777.5 kHz USB (and 6777.7 kHz USB) earlier today. 

Peskies / UNID Spanish Language 6835 kHz LSB 0330 UTC 6 April 2017

More Spanish language traffic on 6835 LSB (previously unlogged frequency) late this evening.  Similar to traffic heard on 6915 kHz (except this is in Spanish!). 

Very heavy storm noise / lightning static making copy very difficult at 0330-0338 UTC

Very loud two-way "pescadore" traffic coming in late this Wednesday evening.  Reminds me of the guys usually heard on 6925 LSB, lots of chatter, basically nonstop, stations talking over each other, etc.

Lots and lots of storm static tonight making copy difficult even with stronger signals.
