Peskies / UNID Portuguese Language 6666.6 kHz USB 0600+ UTC 13 April 2017
« on: April 13, 2017, 0658 UTC »
SIO 122 overall.  Weak signals but relatively quiet band at the moment.  Pescadores for sure (typical peskie behavior, stations talking over each other, people singing etc

...and, of course, an easy-to-remember frequency  ::) ;D

Peskies / UNID Portuguese Language 6985 kHz USB 0630+ UTC 13 April 2017
« on: April 13, 2017, 0632 UTC »
Very heavy fading making confirmation of language difficult.  Sounds like Portuguese but could be Spanish.  Several stations talking over each other at once with rapid QSB. 

at 0632, signal faded up nicely to confirm that it is in fact Portuguese.

Peskies / UNID Spanish Speaking Pescadores 6999 kHz USB 0600+ UTC 13 April 2017
« on: April 13, 2017, 0628 UTC »
The 6999 kHz crowd is back and much stronger than they were last time I heard them. 

OM talking about his Honda engine on his boat.  SIO 444 at peaks.  Both stations peaking nicely at S5-S6.  Frequent references to "barca" (boat).  One of the two stations has large amounts of wind noise and background engine noise in his mic.  Sounds like fishermen - pescadores!  But instead of half a dozen stations talking at once a la 6925 kHz LSB...there are only two stations on this frequency (at least right now). 

Since they're using 6999 USB, the peaks of their SSB signals easily make it past 7000 kHz to 7002 kHz...making them official intruders on 40 meters [dramatic music] lucky for them the closest CW signal (at least during the time the fishing boats were chatting on 6999 kHz) was at 7006 kHz.

Peskies / UNID French or Portuguese 6683 kHz USB 0611 UTC 13 April 2017
« on: April 13, 2017, 0617 UTC »
Weak signal on 6683 USB heard around 0610-0612 UTC 13 APR 2017

Too weak to tell language for sure but sounded like French to me.  Possibly Portuguese with some minor QRM from a nearby digital signal.

Peskies / 6728 USB vs 6731.5 LSB vs. 6731.6 AM Messy 0600 UTC 13 April 2017
« on: April 13, 2017, 0607 UTC »
Two QSOs going on at once and causing terrible QRM, both appear to be in Portuguese but its hard to tell for sure. One on 6728 USB is slightly stronger. Another QSO going on at the same time on 6731.5 LSB, and further complicating matters is a carrier sitting on 6731.57 kHz (rounding up to 6731.6 kHz).  The carrier has very weak modulation, with progressively weaker tones showing up on the waterfall at 200 Hz intervals.  That is, a strong carrier with 5 weaker "carriers" on either side of it.  Going up from center, 6731.8 kHz, 6732.0 kHz, 6732.2 kHz, etc.  Going down from center, 6731.4 kHz, 6731.2 kHz, 6731.0 kHz, etc.  The lower side band of this odd AM signal is making listening to this already very messy frequency that much more, well, messy.

Peskies / UNID Spanish Language 6705 kHz LSB 0550 UTC 13 April 2017
« on: April 13, 2017, 0555 UTC »
Spanish language traffic with some very deep fading/QSB.  S2-S3 signal strength, speaking to S4 at some points but clear frequency so easy copy.

Peskies / UNID Spanish Language 6887 kHz USB 0530+ UTC 13 April 2017
« on: April 13, 2017, 0553 UTC »
Two OMs chatting away, strong signals with nice audio...SIO 444 (which is rare for these types of stations).  Strong data signal 2-3 kHz down on 6885 or so.  Good frequency choice on the part of the pescadores/freebanders (for a change).

Peskies / UNID Spanish Language 6543.2 kHz LSB 0640++ UTC 12 April 2017
« on: April 12, 2017, 0647 UTC »
Strong Spanish language traffic on another interesting frequency.  6 5 4 3 2...now that's easy to remember.  Just like 6777.7 kHz or 6888 kHz, etc.  6543.2 kHz is another case of fishing fleets using HF aircraft bands (in this case, the 6 MHz aeronautical band 6525-6765 kHz), not to mention their use of LSB instead of USB. 

Two OMs talking rapidly with long breaks of silence.  Appears to only be two stations (as opposed to many peskie loggings, where there's 3+ stations, often with several stations transmitting at once. 

I tuned away at 0647 UTC and the frequency was clear when I tuned away.

Peskies / UNID Portuguese Language 5540 kHz USB 0635+ UTC 12 April 2017
« on: April 12, 2017, 0639 UTC »
Yet another 5 MHz aeronautical band pirate/peskie/who knows logging.  This time its 5540 kHz (compare to previous logs for 5510 kHz USB and 5534 kHz USB).  Googled 5540 kHz and 5540 USB and found nothing but information on shortwave broadcasters who use (or have used) 5540 kHz.  Nothing about aircraft or military users of this frequency. 

The 136th edition of the Spooks Newsletter NSNL 136 lists the frequency 5540 kHz as being used by station S30.

Peskie-like chatter in Portuguese with some sort of faint data signal underneath the voice traffic.  Very long winded transmissions (also typical for peskies) with very little to no radio discipline, which leads me to believe that its not aircraft stations using a different language or military/government/diplomatic traffic.

Two romance language stations (I put Spanish in the title but after listening for a bit I think it may actually be Italian) chatting away.  Another unlisted HF aircraft frequency being pirated by non-aircraft users.  SIO 333 at best with static crashing and very minor fading.  One of the stations has some sort of background chatter, possibility indicating it being a marine-based transmitter. 

Falls within the 5450 kHz - 5730 kHz 5MHz HF aircraft band.  Quite close to the 5505 kHz USB MWARA frequency for New York Radio.

Peskies / UNID Portuguese Language 5534 kHz USB 0620+ UTC 12 April 2017
« on: April 12, 2017, 0627 UTC »
Doing some late night (er...early morning) band scanning and came across another "pescadore net" on 5534 USB.  5534 kHz lies within the 5450 kHz to 5730 kHz aeronautical band but 5534 does not appear to be an assigned on-route HF aircraft frequency. 

Radio traffic is similar to the standard peskie two-way traffic heard in the 6-7 MHz region and on other frequencies.  Heavy static crashes and relatively weak signals gives these stations a SIO 222.

Other / HF Marine Nets 6230 kHz USB and 6270 kHz USB 0330+ UTC 11 April 2017
« on: April 12, 2017, 0336 UTC »
Two groups of marine stations chatting away on 6230 kHz USB and 6270 kHz USB.  6230 kHz is one of the few 6 MHz marine band [6200 kHz - 6525 kHz] simplex only channels (according to the ITU channel plan anyway). 

6230 kHz USB - Spanish language
6270 kHz USB - Italian language

Both nets are coming in nice and strong late this evening (US East Coast).  Nice to see marine users actually using legal HF marine frequencies within the legal HF marine bands!

Other / HF SSB Marine ITU Channel 601 6200 kHz USB 0300+ UTC 12 April 2017
« on: April 12, 2017, 0332 UTC »
Tuning around the 3-8 MHz region this evening, right at the bottom of the 6 MHz marine band and I came across a simplex QSO on 6200 kHz USB.  Per the ITU HF SSB maritime frequency channel plan, 6200 kHz is ITU channel 601 and is a "duplex" channel (split-frequency) paired with 6501 kHz.  6200 kHz USB is the ship transmit frequency and 6501 is the coast transmit frequency.  6200/6501 is listed as one of the "USCG Calling" channels which makes sense given the fact that the US Coast Guard uses 6501 kHz USB for marine weather transmissions.  

The users are speaking Spanish and are operating in single-frequency only (nothing heard on 6501 kHz).  Per ITU channel plan, only 6224 kHz, 6227 kHz and 6230 kHz may be used for simplex operation.  

Maybe I've stumbled upon some fishermen actually using real legit MF/HF marine radio with the pre-programmed ITU channels!  [gasp!]

Still going strong at 0332 UTC.

North American Shortwave Pirate / Old Time Radio OTR 6770 kHz AM 0130 UTC + 12 April 2017
« on: April 12, 2017, 0141 UTC »
Hearing bits and pieces of Old Time Radio pirate on 6770.0 kHz AM.  Pescadore QRM from two-way traffic on 6771 kHz USB making reception difficult.  SIO 333 at best.
