Hearing very weak Portuguese chatter on 6965 kHz LSB.  Several stations talking over each other, classic "peskie" chatter. 

2252
At around the same time 6900 kHz LSB started showing signs of activity, I noticed nearby frequency 6905 kHz LSB is also active.  Hearing two or three Spanish speaking stations chatting on 6905 LSB at 2155 UTC / 2156 UTC.  SIO 222 - SIO 333 right now, but its still relatively early for activity on these frequencies.

Considering the fact that 6900 LSB is also active earlier than usual, hopefully these frequencies will stay busy later on and I'll be able to do some more in-depth monitoring of the freebanding radio operators that hang around below 40 meters.

Noticing traffic on 6900 kHz LSB / 6.900 MHz LSB a bit earlier than usual this afternoon (U.S. east coast time anyway).  Tuned in to 6900 kHz after seeing voice traffic on the waterfall while listening to 6880 kHz. 

Sporadic signals, not like the frequency is (will be?) later on in the evening.  Possibly an indicator of a busy night to come.

Equipment / Re: 11 meter rig
« on: May 10, 2017, 2151 UTC »
I've had exceptional results with a regular old half wave dipole on 11 meters.  I agree with the posters who have recommended a vertical antenna (if you have the space to put one up - it doesn't have to be anything crazy like an Antron 99, IMAX 2000, etc - a 1/2 wave or 1/4 vertical do well, a 5/8 wave vertical will do better).

Likely Unknown Name Radio Network UNRN.  Hearing music with some fading on 6880 kHz / 6.880 MHz this afternoon on the Ohio remote SDR.  S4-S5 signal with decent modulation.  

At around 2146 UTC or so, a data signal appeared on the lower side band, 6878 kHz.  Signal strength has decreased a bit, carrier easily visible on the waterfall but modulation noticeably weaker.  Hopefully that will reverse itself in the next little bit.

Looks like flexoman also emailed them (twice!) about their 6070 kHz transmitter audio problems.  Looks like 11775 kHz has the same audio distortion problems.  They've been broadcasting for a while with these issues. 

2257
I'm listening to 11775 kHz AM right now (1850 UTC) May 10th, 2017 and the audio is extremely distorted, more or less impossible to understand what's being said.  Signal itself is strong, but there's something seriously wrong with the audio.

Awesome story, Pigmeat. 

It seems like this sort of thing is found pretty much everywhere truckstops are found.  Since nearly all over the road trucks have CB equipment of some kind or another, channel 19 is the logical place for a truckstop whore to advertise her services.  There's a truckstop north of the city I live in that has a CB shop advertising itself on channel 19, on top of truckers asking each other for things like TVs, potato chips (which makes your story that much better), CB equipment, and other random things the trucker may or may not have swiped from the load he's carrying. 

Wouldn't surprise me if methamphetamine, ephedrine and other "trucker speed" stimulants are sold via CB.

Peskie Relay Service?

Utility / Re: For the CW buffs...22MHz JA Marine.
« on: May 09, 2017, 2341 UTC »
Interesting. I find the Japanese fishery radio systems fascinating. It's a mixture of HF, VHF low band, 26-27 MHz AM, SSB, data systems on 27MHz, UHF-FM, and of course VHF-FM marine band.  They use CW, and all sorts of data formats. I would love to hear some of the 26-27 MHz AM/SSB traffic related to the weird 26760-27988 kHz / 26.760-27.988 MHz 1 watt DSB fishery radio service or the 27.3-27.5 MHz 25 watt SSB fishery radio service.

Looks like Russian UNID traffic has been monitored on this frequency as well:

Huh? / Re: A North Korean Nuclear EMP Attack? … Unlikely
« on: May 09, 2017, 1919 UTC »
http://www.wnd.com is not exactly... reliable  ;D

I would not be surprised if the US/Russia/China have undeclared orbiting nuclear weapons for EMP purposes (even though it violates treaties), but this is a bit beyond NK's capabilities at present.

Wasn't there a James Bond film with that being a major part of the plot?

Josh makes an interesting point re: Russia/China "hiring" North Korea/DPRK to do their dirty work for them, but I don't think NK would do such a thing.

Hearing Radio Saudi (BSKSA Holy Qur`an Riyadh transmitter, 500kw) on 11820 SIO 555 with S9+10 signal strength and WRMI (Overcomer Ministry / Brother Stair USA Okeechobee Florida transmitter, 100kW) on 11825 kHz SIO 555 with S9+20 signal strength heterodyning the hell out of each other. 

Interesting to hear two powerhouse religious broadcasters going neck-and-neck on adjacent frequencies.  Listening to 11825 kHz shows considerably worse interference from 11820 kHz, indicating that Radio Saudi is transmitting a wider signal.  I'm sure the 400 extra kilowatts helps too. 

I checked several remote SDRs around the USA and on the East Coast of the US.  One can watch the WRMI signals match up on the waterfall - easy to compare 11580 kHz (another strong WRMI signal) and 11825 kHz.

Looking-Glass, I continue to be impressed by your monitoring and logging efforts, especially the focus you make on aircraft, utility, marine and unidentified / UNID transmissions.  Of course, that focus is the focus of HF Underground.  Your location in Australia provides a unique perspective on activity that a lot of listeners can't hear.  I recently added a Japanese remote WebSDR (technically a KiwiSDR) to my "International SDRs" bookmark folder, with the plan that I can use it to listen to the frequencies you've posted if I'm up in the middle of the night/early morning.

You mention that the callsigns/stations you've heard are alphanumeric references (A-338, D-676, etc).  Are they identifying using a phonetic alphabet?

So now we know they're using 8076 kHz / 8.076 MHz USB as their primary frequency (daytime frequency?) and 2840 kHz / 2.840 MHz USB as their alternate frequency (maybe nighttime frequency?)  - seems like most of these HF nets have at least two frequencies, at least in my experience and research but there's always exceptions.  Thanks again for continuing to monitor this interesting net.

It wouldn't surprise me if they were using different transmitters and/or different antennas (which would explain some signals and some times being cleaner/stronger than others).

I'm listening to HM01 on 11635 kHz / 11.635 MHz at 1830 UTC 9 May 2017.  Voice and data bursts with YL reading numbers in Spanish.  S9 to S9+10db signal SIO555 with very little noise, even when the carrier isn't modulated.
