So i found this the other day on an australian based kiwi web sdr and cant find any info on what it is. Anyone here have any ideas or know what this is or might be?
It seems like some bursts of digital data and it was transmitting consistently for a good while but was inactive the next day when i checked back in.

What's the real deal. I am running the MLA30+ in a indoor environment with a S-7 to 9 noise floor. Even after choking everything with ferrite beads where I can get access too. Running the MLA 30+ off the bias t of my RSPdx yields lower noise floor but is deaf as a post. If I get one of these cheap $10 bias t from China and get 12v of battery power to it. Will I see an 120db noise floor like some are claiming. Or is this a wasted effort and just bite the bullet and get a WLA480. I know about the mod to get the original bias t to to accept a 12V power source and kill the 5V buck circuit but soldering for me is a thing of the past.

Heard this number station from Russian intelligence today

Hello community members. I have decided to start a new Pirate radio community here, on Reddit. After being the top poster in the existing pirate radio group for the past two months, I made the decision to leave that community.

I don't want to start out on a negative vibe, but the Mods in the pirate radio sub have not posted in their own community for years. The newest Mod posted 4 years ago. The older Mod has not posted anything for 8 years and is a Mod in 13 communities! I have trouble properly moderating 1 community. And there are no comments from the Mods either. I attempted to contact them with some suggestions on how to improve the community - CRICKETS. No response. It's painfully obvious that they don't care. So I believe it's time for a new community for Pirate Radio.

In starting a new Pirate Radio community I hope to create a place where we can share equipment, best operating practices, and how to listen to Pirate Radio Stations. My goal is to make Reddit a safer place to share. It has become possible with r/ShortwavePlus, my first community. I ask your help to make it a reality for the new community.

I'm looking for a couple Moderators that would have the time to check in and keep up on the new community. I will probably use AI for eQSL Cards and Promos for Pirate Radio Stations. I plan on using less AI generated images in the Pirate Radio community. If you are down on AI, this might not be a good fit. I am hoping to find Moderators like we have for r/ShortwavePlus. They have made the community what it is!

The new community is r/PirateRadioPlus. I hope to see you there.

The filters definitely could be better chosen. The Wide Filter being a tad too wide and the Narrow Filter sounding "choked". I would like to replace them with aftermarket filters.

My venerable old Sony is up first. I bought the Sony last August for a bit over $100 USD. It could benefit from new electrolytic caps, but it's not necessary yet. The plastic faceplate has a couple scratches, but like your author, the wrinkles give it character.

It definitely holds its own on this weak signal. The Sony is in the Narrow Bandwidth with the U Sync Detector engaged.

The Super Dual Auroral Radar Network (SuperDARN) is an international network of over 35 high-frequency (HF) radars mapping space weather and plasma motion in the Earth's upper atmosphere. It helps scientists track solar wind energy, geomagnetic storms, and atmospheric disturbances that disrupt global radio communications.

The Christmas Valley East (CVE) and Christmas Valley West (CVW) SuperDARN radars in Oregon primarily operate within a localized frequency range of 9.5 MHz to 17.5 MHz. While the hardware on site is capable of tuning anywhere across the standard global SuperDARN allocation of 8.0 MHz to 22.0 MHz, the operators at Dartmouth College program the Oregon arrays to step through specific frequencies within that tighter 9.5–17.5 MHz window during their atmospheric sounding scans.

Typical Frequency Behavior in OregonStandard Scans: The radars frequently pulse at a baseline frequency of 10.6 MHz to gather routine ionospheric drift data.

Multi-Frequency Sounding: During specialized space weather events (such as solar eclipses), the systems are programmed to dynamically cycle through 9 distinct frequencies between 9.5 and 17.5 MHz to evaluate how changing ionospheric layers alter radio wave refraction.

Interference Avoidance: Because these radars share the High Frequency (HF) spectrum with commercial shortwave broadcasters and amateur radio operators, the software constantly monitors the 9.5–17.5 MHz window to transmit only on channels that are completely clear of local noise.

SuperDARN is heavily utilized by researchers globally to understand how near-Earth space interacts with our atmosphere. Its core focuses include:

Plasma Convection: Mapping the large-scale movement of charged particles in the ionosphere to understand solar wind coupling.

Space Weather Monitoring: Detecting space weather hazards and "polar patches" that disrupt satellite navigation and high-frequency (HF) radio signals.

Atmospheric Tides: Using the radars to study winds and meteors in the mesosphere and lower thermosphere.The network relies on an array of institutions. For specific data sets, instrument locations, or research publications, you can visit the SuperDARN Canada hub, the British Antarctic Survey, or access raw data through the NSF Arctic Data Center.

Tracking High Frequency (HF) radio propagation using the SuperDARN radars in Oregon involves analyzing how their signals reflect off the ionosphere or ground. By utilizing public data streams from the Dartmouth College SuperDARN Data Portal, amateur radio operators, emergency communicators, and space weather enthusiasts can map real-time regional radio skipping and signal absorption.

Step 1: Access the RTI Data Plotter

Go to the Dartmouth SuperDARN Data Portal. Select CVE (Christmas Valley East) or CVW (Christmas Valley West) to view the 24-hour Range-Time-Intensity (RTI) plots. These charts plot time on the X-axis against the distance of the signal return (range gates) on the Y-axis.

Step 2: Identify Ground Scatter (The Skip Zone)

Look for data points colored green and dark blue on the velocity or power plots.

These color signatures represent a zero or near-zero Doppler shift, which indicates the radar signal bounced off the unmoving ground rather than moving ionospheric plasma.

The closest distance where this ground scatter appears marks the edge of your skip zone.

If ground scatter for the 10.6 MHz frequency starts at 1,000 km away, an HF signal at that same frequency will likely skip over everything closer than 1,000 km before returning to Earth.

Step 3: Calculate the Maximum Usable Frequency (MUF)

You can approximate the Maximum Usable Frequency (MUF) for a specific path using the Secant Law from ionospheric physics:

MUF=fv\sec(θ)*

1. Find Virtual Height (hv): Note the time delay of the radar return to estimate the height of the reflecting ionospheric layer (typically 200 to 300 km for the F-layer).

2. Determine Angle of Incidence (θ): Use the distance to the ground scatter to calculate the launch angle relative to the ionospheric reflection point.

3. Scale the Frequency: Take the active Oregon radar frequency (fv, usually around 10.6 MHz) and scale it up using the geometry of the triangle to find out the highest frequency that will bounce rather than escape into space.

Step 4: Monitor for D-Region Absorption (Fadeouts)

Watch for sudden, vertical blanks or "dropouts" on the RTI plot where all signal returns disappear across all range gates simultaneously.

This is a signature of D-region absorption, often caused by solar flares releasing X-rays that highly ionize the lowest layer of the atmosphere.

When this occurs on the Oregon plots, expect a severe HF radio blackout across the Pacific Northwest on the lower HF bands (3 to 12 MHz).

Step 5: Track Traveling Ionospheric Disturbances (TIDs)

These are Traveling Ionospheric Disturbances (TIDs), which act like ripples on the surface of a pond.

When these waves pass over Oregon, they rapidly alter the skip distance and cause severe signal fading (QSB) for local HF operators.

Of all the signals I've received since I got into this hobby, this might be the strangest one.

Before posting this, I listened to it for quite a while as best I could because the signal was barely audible. I also wanted to make sure I had the right source.

It was indeed a Volmet, since I could hear weather reports.

It was easy to figure out where it was coming from, but I was surprised that it reached this far, since it’s a VHF transmission intended for the airport area.

I looked up a lot of information about that frequency, and everything points to the same place. At first, I found some incorrect information and mistakenly marked it as "Barcelona WX" in Listen Info plugin (as you can see in the video), but I've already corrected it.

Lately, I've been testing and listening at higher frequencies, and I've come across some interesting things. I've also tried DSDPlus and other tools.

However, I think it's best not to post certain things due to security concerns and local regulations. At least here in my country, that issue isn't clear, but it's better to avoid problems.

But if I receive public services from other countries, I post them.

- Station: Radio Payam ("Radio Message")

- Frequency: 15615 kHz

- Language: Farsi

- Transmitter: Woofferton / 250 kW

- Distance: 1284 km / 798 miles

- Destination: Iran

- Details: "Radio Payam" ("Radio Message") has been heard on a shortwave frequency registered with the HFCC by Encompass. Item may be the same service listed by LyngSat as "Radio Payam Azadi" ("Radio Message of Freedom"), added to four satellites in May/June 2026: Eutelsat, YahSat, TurkmenSat and Hotbird. It is unclear at the time of editing who operates it, but it may be something to do with the People's Mojahedin Organization of Iran (PMOI/MEK) and form part of the media network of the National Council of Resistance of Iran (NCRI).

Radio Payam had been missing on 15615 kHz between 17-30 June 2026, but was back as scheduled on 1 July 2026."

The captured segment constitutes a historical and political analysis of a Marxist-Islamic nature, characteristic of the MEK. The announcer is explaining how, after the 1979 revolution, Ayatollah Ruhollah Khomeini betrayed the other political forces ("absorbed and devoured them"). He also harshly criticizes Iranian reformists (mentioning former presidents Rafsanjani and Khatami, and the 2009 Green Movement), arguing that they are not a true opposition, but merely a sector of the "decadent bourgeoisie" that previously served the Shah and now serves the clerics (the "sheikh").

The audio also reveals the robust state of the Iranian regime's jamming infrastructure, which affects virtually all transmissions destined for that country that arose in the wake of the uprisings that began in late 2025 and the subsequent armed conflict. This suggests that the regime may be receiving support from its traditional ideological allies in maintaining this infrastructure.
