10/11 meters / 11 meters is active 2045 UTC 10 July 2019
« on: July 10, 2019, 2058 UTC »
Via COMMSIGMA KiwiSDR, from 2045 UTC to 2055 UTC (1645 to 1655 local time)

26.065 MHz AM - two OMs talking, "nearing 100 mile there" "closer to the city" - sound like truckers, southern accents
26.105 MHz AM - similar traffic to traffic heard the other day, truckers or similar traffic
26.405 MHz AM - weak AM carriers fading in and out
26.565 MHz AM - OM doing radio checks
26.775 MHz AM - southern-accented OMs
26.885 MHz AM - similar to 26.915 MHz AM, heard the frequency referred to as "885"
26.905 MHz AM - central US stations heard, Illinois mentioned
26.915 MHz AM - very busy, several stations talking at once, heard a station ID'ed as "Jailbird"

not all 40 legal CB channels were active, the usual AM and SSB activity centers were busy, including 27.385 LSB

27.465 MHz LSB - active with DXing stations, general rag-chewing
27.575 MHz AM - "you going down to where? 700?" "you must have lots of spray"

Not as busy as it was yesterday, but still a considerable amount of DX rolling in this afternoon

Hearing two truckers chatting on 26.405 MHz AM / 26405 kHz AM, both with good signals.  Talking about trucking related topics (company drama, weigh scales, several mentions of "Toledo" and "75" - presuming that's a reference to I-75 or route 75).  At one point it became clear the two operators were within eyesight of each other, likely a "company channel" or "side channel" used by truckers from a particular location or company...several other 26 MHz frequencies are waking up early this afternoon.  Hearing two OMs chatting on 25.925 MHz AM / 25925 kHz AM, both of them seem to be local to each other as well.

Foul-mouthed Spanish speaking fishermen (or freebanders, both, I suppose) on oddball frequency 9161.3 kHz 9.161.3 MHz USB 9161.3 USB.  At least two different stations involved, all the usual Spanish language curse words heard. 

Peskies / 6925 kHz LSB - The Usual Suspects 2112 UTC 8 July 2019

6.925 MHz LSB 6925 kHz LSB 6925 LSB Portuguese chatter - several stations going nearly non-stop.  SIO 222 or so.  Lots of thunderstorm crashes and static this afternoon. 

Radio Free USA pirate station 6931 kHz USB 6.931 MHz USB July 5th, 2019

Audio clips about impeachment - Radio Free USA ID at 1607 UTC

1608 UTC - "Keep America Great"
1611 UTC - Radio Free USA ID

"Keeping my SWRs down" at 1415 UTC.  "I'd say everything looks fine" 

Two OMs chatting about radio-related topics with some minor QRM from 27.125 MHz (channel 14) and 27.135 MHz (channel 15).  Very weak data bursts noted underneath one of the stations.  AM voice on 27.145 MHz - R/C frequency A channel +10 kHz channel.  27145 AM.

"Star Spangled Banner" by Jimi Hendrix coming in nice and loud on the COMMSIGMA KiwiSDR on the CT/MA border this morning.  CB CH 32 music on CB radio channel 32 27.325 MHz 27325 kHz AM mode.

10/11 meters / 11 meters is active 1400 UTC 5 July 2019

July 5th, 2019.  Lots of 11m activity, both within, above and below the legal 40 CB channels.  Lots of AM activity on the usual AM DX channels, but activity noted below channel 1 and lots of SSB activity above channel 40. 

The usual Spanish language chatter active this morning on 6900 kHz LSB 6.900 MHz LSB "The Home Channel" - freebanders on 43 meters SS OMs chatting away.  CB-like talking on 6900 LSB. 

Via the Westminster, MD KiwiSDR.  Two OMs chatting away about la calle ("the street" literally).  At 2024 UTC, a third station joined in.  Seems like freebanders or maybe fishing boats.  One of the stations has some background noise.  Considerable fading. 

10/11 meters / 11 meters is active 2030 UTC 25 June 2019

26.915 MHz, lots of in-band frequencies, 27.390 MHz LSB, 27.425 MHz LSB, 27.475 MHz AM (then switched to LSB) and several other out of band frequencies active at 2030 UTC.  26915 AM is quite busy.  27.385 LSB/Channel 38 LSB as well as 27.025 MHz AM/Channel 6 AM going non-stop. 


Too much of a coincidence that it occurred on Argentina's election day and right after the New York Times reported on US Cyber Command's installation of sit-and-wait malware in the Russian power grid (in response to the Russians doing the same thing to us for years now - cf. https://www.us-cert.gov/ncas/alerts/TA18-074A)? 

While the various governments (Argentina mostly, but also parts of Uruguay, Paraguay, Chile, etc.) seem to be willing to rule out cyberattack as the reason for the massive blackout that affected more than 40 million people (!!) it seems like somebody is doing another test, proof of concept, whatever you want to call it.  Combine with the recent airnav GPS issues. 

Time to buy more solar panels, batteries, and, of course, can openers.  Also ammunition.  Battery-powered HF and VHF/UHF capability.

Would have been nice to have a before/after waterfall image for MF/HF/VHF/UHF in Buenos Aires when the lights went out.  See how much the noise floor drops (and see which broadcast stations, etc. went off the air).

This is becoming almost a daily thing now - another North American 11-meter opening this afternoon (east coast time).  Noted activity on 26.105 MHz, 26.685 MHz, 26.905 MHz, 26.915 MHz (all AM), basically every one of the legal 40 CB channels too...and several above CB band frequencies including 27.415 MHz LSB, 27.430 MHz LSB, 27.445 MHz LSB, 27.465 MHz LSB, 27.525 MHz LSB, 27.665 MHz AM (hearing some weak SSB underneath the AM chatter), 27.725 MHz AM and others...

Did some quick 11m band scanning this morning on the way to work (receiver is a Superstar 3900, older style version with Hustler IC-100 mag-mount antenna).  Noticed the usual in-band activity as well as what appeared to be semi-local two-way comms on 25.835 MHz AM (channel 19 on band A, or channel 19 down three bands on the de facto standard 6-band export frequency or channel plan).


Hearing some trucker communications / truck to truck chatter on 25835 AM this morning.  Talking about moving loads up to a meeting point or distribution point.  Two OMs with roger beeps.  No echo noted, but strong AM modulation and rapid fading up and down (indicating that they're moving). 

De facto standard 6 band export 11 meter (10 meter) radio channel plan.  Band D is the CB band (or the mid band 26.965 MHz to 27.405 MHz), Band C is the low band (26.515 MHz to 26.955 MHz), band E is the high band (27.415 MHz to 27.855 MHz).  Band B is the low-low band (26.065 MHz to 26.505 MHz) and Band A is the super-low band (25.615 MHz to 26.055 MHz).  So if the CB band is band D, channel 19 is 27.185 MHz, down one band is 26.735 MHz (band C), down two bands is 26.285 MHz (band B), down three bands is 25.835 MHz (band A).    This is the standard 6-band / 240 channel export radio channel plan.  Up one band would be 27.635 MHz (band E) and up to bands would be 28.085 MHz (band F).  One "band" is 0.450 MHz / 450 kHz.  Truckers love to flip the band switch up or down to find a clear frequency, instead of touching the channel knob, its easier to leave the channel setting where it is, and simply flip the band switch.  Because of this, the common trucker channels on the various A-B-C-D-E-F bands are popular places for AM activity during band openings.  Channel 19 is the obvious starting point, but channels 14, 15, 16, 17, 18, 20, 21, 22, 23, etc. are also popular.  I've noted trucker comms on 26.775 MHz (channel 22 down one band), 27.535 MHz (channel 11 up one band), 27.605 MHz (channel 15 up one band), but 27.615 MHz, 27.625 MHz and 27.635 MHz are all very popular (channels 17, 18 and 19 up one band).

Maybe this is the beginning of another band opening (yesterday I heard what sounded like several different business or trucking company comms on various 26 MHz frequencies in Band B (26.065 MHz to 26.505 MHz) and on the high channels (Band E), including 26.325 MHz, 26.365 MHz, 26.375 MHz, 26.405 MHz, as well as 27.585 MHz, 27.655 MHz, 27.755 MHz and 27.775 MHz, all AM mode.
