Brazilian MilSat Pirates

Not Shortwave but definitely an oddity. Brazilian MilSat Pirates on 253.850 MHz FM (UHF Military Band). From the past 19 SEP 2015 at 16:32 UTC from the Pacific Northwest, USA. Receiver is an AOR-3000A using a discone antenna and a 15 dB preamplifier.

While communications using the US's Fleetsatcom Network of satellites was being migrated to a newer system, the older satellites were still operable. The Brazilian Pirates took full advantage of the unused satellites. These guys are in the Amazon and are most likely Truckers delivering supplies to remote villages. A lot of these villages were similar to the 1890's "Gold Rush" towns in the US. Built in a hurry to take advantage of the resources that the Amazon Basin had to offer.

Most Truck Stops were able to modify commercial amateur radio FM 2 meter transceivers to operate on the MilSat frequencies so there was no shortage of radios. Since there were no cell phone networks in this area, the pirated MilSats were perfect for their use. Several times US Agents and Brazilian Police raided the Pirates, especially those residences that sported UHF antenna on their roofs!

Best External Antenna Retekess TR110

I just bought a Retekess TR110. I'm a newbie and not an expert. I want to buy a good portable external antenna that directly connects to the port. I know there are antennas with crocodile clip attachments, but that's not what I want. Any suggestions? I'm based in the UK.

Indonesian "Horse Races"

6965 KHz LSB at 11:30 UTC on 30 OCT 2024. Received in the Pacific Northwest, USA with an AirSpy HF+ Discovery and 20 meters length end fed random wire antenna.

Now here's something you might not hear very often. These are Indonesian Radio Pirates that engage in unlicensed communication just below the 40 meter amateur radio band. They operate on multiples of 5 or 10 KHz, 6965, 6975, 6985, or 6970, 6980, KHz etc. I can hear them most Fall mornings from 04:00 - 07:00 Pacific Daylight Time. These gentlemen can be carrying on a conversation amongst themselves, and then break out into a chant. The chanting is known as Horse Racing and the winner is the operator that chants the longest and the loudest! Hope you all enjoy this radio oddity.

GRUNDIG Satellit Q

I have a few. My fave is 6001 for the audio quality and insane number of controls -- I was was attracted to complexity in various apparatae at the tender age.

Which one is yours?

AC power adapter causes lot of static noise

I recently bought an AC adapter from Amazon for my Sony SW7600G and found that it injected so much noise that shortwave listening was impossible. Even for FM reception, there was still lot of noise out of the speaker. So I returned it and bought another from a local BestBuy store, that gave much cleaner power. FM reception much improved, some improvement with SW reception. Nevertheless, when the radio is powered with 4 AA batteries, receptions are crystal clear on FM and 100% improvement on SW. 

Is there a way to reduce noise from AC adapter? The one I use now has range 3-12V that I set to 6V for my radio. From my experience, the quality of the AC adapters matter. However can I use a power line noise/EMI filter between the wall outlet and a better quality AC adapter to deliver cleaner power to the radio?

Advice Please For Best Multi Band Portable Receiver

It all started with me seeing an ad for the Retekess TR112, I really liked it. I'm new to this and now I have an itch to buy a portable radio with as many bands as possible, i.e., SSB, CB Band, Airband, etc., purely to eavesdrop and listen to random stuff. My budget is $100 ish (flexible). I have been watching numerous YouTube videos on Raddy, Retekess, Tecsun, and similar. I guess I have information overload and am overwhelmed with choices now. What are some opinions from the experts out there? Your advice would be very welcome in helping me make my choice. Thanks.

UPDATE: OK, so I'm now looking at a Raddy RF919 (I've increased my budget). Do you have any comments, pros, or cons from you experts out there?

ATS-20+ POS DEVICE

Title for attention but some truth, I recently had a friend suggest I get a ats-20+ because of my interest in shortwave ssb radio frequencies. I got the device hooked it up and…… can’t hear jack shit besides fm radio and some shitty local am stations, what am I doing wrong? Did I just waste $35? Do I really need to get a giant ass antenna? I Live in central Colorado.

Edit- thank you to everyone who has some input, as a green sw guy I really appreciate it.

China Radio International ATS-909

China Radio International's English language service on 9645 KHz at 12:15 UTC 28 OCT 2024, from Beijing, China. 500 kw station received in the Pacific Northwest, USA using a Sangean ATS-909 with a 20 meter length end fed random wire antenna and homebrew passive preselector. This is Sangean's second version of the ATS-909. I also own the initial version, which has a gold case, and the Radio Shack Version DX-398. I have modified this ATS-909 by replacing the weak dial illumination LEDs with brighter LEDs. Note: obviously this is not the X or X2 version.

FEBC Philippines Kaito KA1103

FEBC Radio Liangyou on 9400 KHz at 10:55 UTC 28 OCT 2024, from Iba, Philippines. Cantonese language service 100 kw received in the Pacific Northwest, 19,650 km (6,618 mi), using an original Kaito KA1103 and a 20 meter length end fed random wire antenna. I'm also using my homebrew passive preselector. The Kaito was purchased in 2014 and is not the new DSP version. Please don't purchase the new version. It's a poor performer. The following photos show how to tell the radios apart. The older version has "PLL" in the logo on the front. The Degen DE1103 is the same radio as the Kaito KA1103.

New to SWL and not fonding anything

As the title says here I’m new to SWL. I’m using a Tecsun pl-990 and the an-48 antenna. I’m currently in Utah. I have scrolled and scrolled and tried all the frequencies identified from the helpful websites. I’ve heard a lot of different static, but no voice yet. Any tips or suggestions?

Choyong A8W USB-C Headphones

Just purchased one - very fun radio. However it didn't come with USB-C headphones. All USB-C headphones I've found include a microphone and are intended for phones.

I bought one of these wired earbuds anyway and I'm not getting any sound from the radio. I checked all the radio config settings and didn't see anything specific to turning on headphone sound. I adjusted the volume to high. Still no sound until I pulled the USB-C plug out and the speaker was blaring.

The headphones work fine with my phone. Not sure if the existence of the microphone is the problem, but I haven't found any of these without a microphone.

I haven't heard back from Choyong Support yet. Any ideas? Thank you.
