Microtelecom announces next-gen SDR - Perseus22 receiver


https://microtelecom.it/en

The Perseus22 SDR is a 4-channel, direct sampling receiver with continuous frequency coverage from 10 kHz to 225 MHz and a typical image rejection larger than 70 dB.

All channels are synchronously sampled by a high SNR, 14 bits A/D converter and processed by a software-defined digital down converter, implemented on an FPGA, which outputs are routed to the host PC by a USB 3.0 controller, allowing wide-bandwidth IF applications.

The frequency coverage is split up in 2 groups of channels (two for the VLF-HF frequency range, the others for VHF), each one capable of diversity, which can reduce noise in order of tens dB. All channels include an analog RF frontend equipped with attenuators, preselection filters, and amplifiers.
The receiver enclosure is machined from solid aluminum and finished with a fine, non-reflecting, black surface treatment. 

At the present time, the unit is awaiting FCC-type acceptance and no definitive pricing is available. The target date for release is October 2022.

Familiar players and familiar places. 

Familiar fears pushed by familiar voices.

The world has held its breath during the Russian invasion of Ukraine as images of the human suffering of war have brought back old memories and old fears from years gone by.

Just like these events have brought up once buried feelings, it has also brought what many thought to be “old” technology back to the forefront.  While internet access is one of the first targets of invading regimes intent on controlling the narrative, the vast reach of shortwave radio transcends borders and other forms of connectivity.

It is déjà vu with a front-row view.

For those who want to be on the front lines of the action, Gayle Van Horn’s (W4GVH) 18th Edition of her Amazon bestselling Global Radio Guide (Summer 2022) has all of the details you need to catch up with the latest from the front lines.

As one of the only remaining publications available with international broadcast frequencies and schedules, the Global Radio Guide (GRG) puts everything a radio enthusiast needs to navigate the action right in their hands.

In this completely updated edition, regular GRG contributors Ken Reitz, KS4ZR, and Fred Waterer (both also of The Spectrum Monitor) post feature on monitoring the international broadcasters at the very forefront of the events.  Larry Van Horn, N5FPW, adds his detailed information on monitoring of utilities on the shortwave bands, including military communications. 

With the help of the GRG, you can tune in to shortwave broadcast stations from additional hotspots such as China, Cuba, India, Iran, North/South Korea, Taiwan, and many other counties. If you have a shortwave radio receiver, SDR or Internet connection, pair it with this unique radio resource to know when and where to listen to the world.

This newest edition of the GRG carries on the tradition of those before it with an in-depth, 24-hour station/frequency guide with schedules for selected AM band, longwave, and shortwave radio stations. This unique resource is the only radio publication that lists by-hour schedules that include all language services, frequencies, and world target areas for over 500 stations worldwide.

The GRG includes listings of DX radio programs and Internet website addresses for many of the stations in the book. There are also entries for time and frequency stations as well as some of the more “intriguing” transmissions one can find on the shortwave radio bands.

In addition to the global hotspots, the GRG brings the world to you from other places on the radio dial.

Gayle Van Horn brings us into the tropics with her regular stroll through the tropical bands – one of the most challenging and rewarding pursuits for the shortwave listener.

Not only are the bands heating up with world events, but the HF bands themselves are becoming more alive as our sun wakes up from its slumber.  What impact will this renewed solar activity have on listening?  Tad Cook, K7RA, shares his atmospheric expertise with a primer on radio propagation while maintaining an eye on the ever-evolving Solar Cycle 25. 

A bit lower on your radio dial, DX Central’s Loyd Van Horn, W4LVH, breaks down the basics of getting started with mediumwave DX and even gives us a fun summer project by diving into the powerful KAZ antenna that listeners can use to pull in elusive mediumwave signals from far beyond their home.

Whether you monitor shortwave radio broadcasts, mediumwave, amateur radio operators, or aeronautical, maritime, government, or military communications in the HF radio spectrum, this book has the information you need to help you to hear it all. Teak Publishing’s Global Radio Guide "brings the world to you."

17th Edition of the Global Radio Guide (Winter 2021-22) Now Available

 


Press Release:                                                                         
Teak Publishing Company 
P.O. Box 297
Brasstown NC 28902

For Immediate Release                                                                       Thursday, December 2, 2021

On any given day, the People’s Republic of China (PRC) fueled by a meteoric rise in the country's economics, politics, the covid pandemic, cyber security and human rights issues, Beijing Winter 2022 Olympics, and a strident expansion of the country’s military forces dominates global news headlines and news cycles. These headlines include China’s recent tensions with Taiwan, which are said to be the worst in forty years, and its other neighbors in the South China Sea region.

As China’s influence continues to expand worldwide, so have the country’s huge radio broadcast services. Local, regional, and international mediumwave and shortwave networks carry news and programming to audiences around the world. Since these services are government-sponsored you are hearing China’s Communist Party’s (CCP) perspective of worldwide events as they unfold. Topping the list of the country’s media outlets is China Radio International (CRI) the largest and most widely heard station in China.

For those who want to follow all the ongoing storylines originating from the PRC, Gayle Van Horn’s 17th Edition of her Amazon bestselling Global Radio Guide (Winter 2021-22) has all the details you need to monitor all the radio services from the Land of the Red Dragon.

Her feature is one of the most comprehensive articles ever written on the Chinese radio broadcast system. Complete schedules for all China radio services, a section of how to ID national stations broadcasting in Chinese, and links to videos with CRI IDs in 45 languages on the author’s YouTube channel that are just some of the materials you will find in this all-important cover story in the GRG. This is an indispensable guide for the radio listener to hear China as tensions in the region continue to heat up.

China’s broadcasters are not the only focus of this completely updated edition of the GRG, though. Worldwide, tensions are continuing to escalate, and – in another case of what is old becoming new – people around the world are once again turning to shortwave radio to place themselves on the front lines.

With the help of the GRG, you can tune in to shortwave broadcast stations from other hotspots such as Cuba, India, Iran, North/South Korea, Taiwan, Hong Kong, and many other counties. If you have a shortwave radio receiver, SDR, or Internet connection, pair it with this unique radio resource to know when and where to listen to the world.

This newest edition of the GRG carries on the tradition of those before it with an in-depth, 24-hour station/frequency guide with schedules for selected AM band, longwave, and shortwave radio stations. This unique resource is the only radio publication that lists by-hour schedules that include all language services, frequencies, and world target areas for over 500 stations worldwide. The schedules included in this edition of the GRG are valid from 31 October 2021 until 26 March 2022, the B21 broadcast schedule period.

The GRG includes listings of DX radio programs and Internet website addresses for many of the stations in the book. There are also entries for time and frequency stations as well as some of the more “intriguing” transmissions one can find on the shortwave radio bands.

Gayle has also updated her now-famous SDR Buyer’s Guide, a must-have compendium that helps you navigate through the revolutionary world of software-defined radios (SDRs), the new digital frontier of the radio hobby.

Also new in this 17th edition, James Careless, in an article that originally appeared in Radio World, looks at the current state of shortwave receiver technology. Dr. Adrian Peterson of AWR looks back at the early days of Philippine broadcasting. David Harris has written a review of the bhi NES10-2MK4 Noise Cancelling Speaker. Spectrum Monitor columnist Fred Waterer will take you on a guided tour of shortwave music programs from around the world.

There are updated columns including the latest radio news in Bits & Bytes, current radio QSL information and addresses, the Best of the Best DX shortwave program listings, and a listing of radio station Internet websites.

This edition also has introductory articles for beginners on Traveling the World via Shortwave Radio Broadcasts, Monitoring the Shortwave Action Bands, and Teak’s latest greatly expanded frequency list of HF non-broadcast radio stations worldwide.

Global Radio listeners are routinely entertained with unique perspectives to events, music, culture, history, and news from other countries that you will not see or hear on your local or national broadcast channels. Global Radio broadcasts are not restricted by country borders or oceans and can travel thousands of miles, reaching millions of listeners worldwide, now in over 300 different languages and dialects.

Whether you monitor shortwave radio broadcasts, amateur radio operators, or aeronautical, maritime, government, or military communications in the HF radio spectrum, this book has the frequencies to help you to hear it all. Teak Publishing’s Global Radio Guide "brings the world to you."

Pacific Aero HF/VHF Coverage

 


Mode is USB for all frequencies below unless otherwise indicated.

North Pacific (NP) MWARA
San Francisco 5628  6655  8951  10048  13339  17946  21925 kHz

The North Pacific is considered to be above 37N and west of 150W, west to the Tokyo FIR at 165E, and includes the Anchorage FIR and Russian Airspace. Some checkpoints along the Aleutian chain are in  HF range of remote relay stations; therefore, Anchorage controllers communicate directly with flights along much of their route. Tokyo Radio is the only other radio station using the North Pacific frequency  groups

NP/Polar Routes: Anchorage ARTCC’s current radio voice capabilities in the Arctic CTA do not extend past N75°. Lack of satellite coverage in the polar region affects CPDLC coverage as well. Because of the lack of ATC communications available in the Polar region, SFO provides communications using the NP1 HF family as primary and the Barrow, Alaska LDOCF as a secondary means for these aircraft.

Central East Pacific (CEP) – 2/3 MWARA
San Francisco 2869  3452  5547  6673  10057  11282  13288  21964 kHz
 
Central East Pacific (CEP) – 1/2/3 MWARA
San Francisco  2869  3413  3452  5547  5574  6673  8843  8915  10057  11282  13288  13354  21964 kHz

CEP (Central East Pacific): The Central East Pacific has composite route structures which primarily cover the areas between the Continental United States and Hawaii. It also covers the route structures between Canada and Hawaii. When assuming radio guard on CEP flights, flights will monitor the  primary and secondary HF assignment and set the aircraft transponder unit on code 2000 (also called  squawk Code)
 
South Pacific (SP) MWARA
San Francisco  3467  5643  8867  13261  17904 kHz

SP (South Pacific): Most flights traveling to and from the South Pacific operate during the mid-shift. Generally, the lower frequencies of the SP family are reliable during these hours. Several ground stations share this group: Brisbane, Auckland, Nadi, Tahiti, and San Francisco. Station interference is not normally a problem. Most flights leave SFO radio guard and enter Nadi’s guard. Nadi radio operators (ROs) occasionally work traffic well into the SFO guard area when atmospheric conditions make reading the flights difficult.
 
Central West Pacific (CWP) -1 MWARA
San Francisco 2998  3455  4666  6532  8903  11384  13300  17904 kHz

Central West Pacific (CWP) -2 MWARA
San Francisco 2998  5652  6532  8870  11384  13300  17904  21985 kHz

CWP (Central West Pacific): The frequencies of the Central West Pacific family cover a vast amount of territory. The boundaries of the Oakland FIR have neighboring control authorities and radio stations.  San Francisco shares this frequency group with Tokyo, Manila, and Port Moresby. The West Pacific frequencies are divided into 2 groups. CWP- 1 generally works flights east of 170E and flights traveling between Honolulu and the Orient, and CWP-2 works flights in the Guam area, west of 170E.

San Francisco LDOC (Asia, Pacific, Polar)  3494  6640   8933  11342  13348  17925  21964 kHz

Pacific (PAC) Air/Air (AM) 123.450 MHz
