KNL Networks is developing shortwave-powered global Internet access

Earth

Many thanks to SWLing Post contributor, Steve T, for sharing the following news from Business Insider:

KNL Networks, based in Oulu, Finland, has been in stealth mode during the past four years while developing a revolutionizing system that enables internet connection anywhere in the world – even in the middle of the Pacific Ocean – without using expensive satellite systems.
Today, KNL announced the completion of its series A funding round. The funding amounted to more than $10 million making it one of the biggest Nordic series A rounds. Creandum is the biggest investor.

[…]Facebook and Google have been exploring the possibility of bringing internet to remote locations by relaying data through a network of balloons. KNL’s technology, on the other hand, proposes the opposite: incredibly long range signals, by sending internet protocol over the radio.

KNL’s technology is already being used to provide robust internet connections to ships on the Atlantic and Pacific Oceans, but can be used anywhere on the globe for many different applications.

[…]KNL’s technology relies on shortwave radio transmissions, which can transmit data for thousands of kilometers, for a fraction of the cost of a satellite system. Accomplishing this has required the innovation of long-distance high frequency radio systems. In comparison with satellite internet, the radio technology offers the additional advantages of being easier to use, always on.

This is very exciting news, Steve!

I’ve always had confidence that inherent HF bandwidth and data integrity issues could be addressed with time as our receivers, codecs and digital signal processing improve with each iteration.

As I wrote in, Does Shortwave Radio Have a Future?, I’ve always believed that the shortwave medium could be leveraged for international digital/data communications, and should be. In my article, I focused on Radio Canada International (RCI), which was then dismantling their shortwave transmitter site:

[B]roadcasters should not dismantle their transmission sites as Canada is currently doing. Not only is the current service originating from these sites a more reliable form of emergency communications than the Internet, should a national disaster befall us; not only do they continue to provide a broad-spectrum mode of diplomacy; but should future digital communication modes find a way to take advantage of the HF spectrum as is now under discussion, this would be most unfortunate.

Imagine a wi-fi signal with a footprint as large as several countries, digital devices with tiny fractal antennas that receive this signal containing rich media (e.g., audio and video)––these are not science fiction, but highly plausible uses of these transmission sites, even within the next decade…

We’ll be watching developments at KNL Networks and reporting updates here on the Post. Follow the tag: Shortwave Internet

FlexRadio PowerSDR now incorporates SWLing features!

flexradio-1500Many thanks to SWLing Post contributor, John (AE5X), who writes:

Hi Thomas – I thought you might be interested to know that KE9NS has updated PowerSDR software for Flex 1500, 3000 and 5000 series radios with the following features:

  • SWL BANDS: 14 standard Shortwave Listening bands, each with their own Bandstacking memories.
  • SWL SPOTTER: SWL.CSV database file (from eibispace.de) provides over 11000 shortwave broadcast, utility, and government frequencies all displayed directly on the Panadapter. Right Click on a station to open up a google search.
  • SWL Listing screen: Displays currently operating SWL stations by Frequency and is
  • SEARCHABLE by Station Name. Left Click to go to frequency. Attempts to determine the mode (AM, DIGU, USB, CW).

Here’s a YouTube video demonstrating:

Thank you for sharing this info, John!

I know a number of Flex owners that will be happy with this added functionality. At one point in the past, I considered purchasing a Flex 1500 and using it as both a QRP transceiver and shortwave listening SDR. I’ve held off, though, mainly because so many other affordable receive-only SDRs have hit the market. Someday, I may take the plunge and add an SDR transceiver to the shack, though. Nice to know KE9NS has SWLs in mind.

Post readers: Any SWLs out there using their FlexRadio SDR for SWLing?  I’m curious if you can record spectrum and, if so, how wide the bandwidth can be set. Please comment!

This weekend: MARS communication exercise

Hammarlund-HQ-120X-DialLightMany thanks to SWLing Post contributor, Dan (K2DLS), who writes:

There is a MARS communication exercise taking place this weekend. As
part of the exercise, a MARS station on the east and west coasts will
broadcast a bulletin which will be verified by a QSL.

Please see the notice below:
A HIGH POWER 60 METER BROADCAST WILL BE MADE TO THE AMATEUR RADIO
COMMUNITY THIS SUNDAY 30 OCT AT 2300 HOURS ON 5330.5 USB (60 M). IT
WILL REPEATEDLY RUN A 5 MINUTE BROADCAST FOR AN HOUR ALTERNATING
BETWEEN AN EAST COAST AND WEST COAST STATION. THE BROADCAST WILL
INSTRUCT AMATEUR RADIO STATIONS TO MAKE CONTACT WITH A MARS STATIONS ON
60 METER CHANNELS (INCLUDING 5330.5 USB) AND REPORT LOCAL CONDITIONS.
AMATEUR RADIO OPERATORS WHO RECEIVE THE HIGH POWER 60 METER BROADCAST
WILL ALSO RECEIVE A QSL CARD BY ENTERING A RECEPTION REPORT ON THE
WWW.USARMYMARS.ORG WEBSITE.

VEry cool! Thank you, Dan!

Aeronautical SDR: Ivan’s in-flight FM spectrum captures

Aircraft-Jet-Boeing-VOLMET

Many thanks to SWLing Post contributor, Ivan Cholakov (NO2CW), who writes:

Thomas, not sure if this is something relevant but airlines now state it is OK to use an am/fm radio on board aircraft.

Not much possibilities for AM unfortunately but on a recent flight from Ft Lauderdale to Dallas and Albuquerque I hooked up an SDRPlay receiver to a 3 inch stick antenna and recorded a few stations I was able to pick up along the way.

The first video is posted here:

I did take a few more videos flying between JFK and MIA as well.

I used the following equipment:

fm_dx

1. 13 inch laptop that I also use for work
2. SDRPlay receiver
3. Old scanner antenna that I happened to have
4. SDRUno software to drive the radio
5. Screen recorder that comes with the Win 10 Xbox app
6. Windows movie maker to stitch the individual clips together and annotate

If needed, the size of the setup above can shrink further if a smaller laptop/tablet is used and an RTL dongle instead of SDRPlay.

You will also need to equip yourself with a window seat. Otherwise, signals are significantly weaker.

I did not place the antenna in a special position, just next to me on the seat where it could not be noticed by other passengers. I uploaded a few more videos from my weekly shuttle flights between MIA an JFK.

Wow!  Thanks so much, for sharing this, Ivan.

I’ve always packed a simple FM-capable radio in my one, compact carry on bag and typically try a little FM DX travel while in flight. I was never aware there was a restriction on using an FM receiver in flight, but I’ve always kept my radio listening very discrete so it’s never been a problem.

I love the idea of doing in-flight FM spectrum captures! It would be fun to watch signals on the spectrum shift and change as the flight progresses. Very cool, Ivan!

Post readers: Have you ever made in-flight FM spectrum captures like Ivan?  Please comment!

DRMNA: Interview with Mike of PantronX, maker of the Titus II

titus 2 big

Those of you following the upcoming Titus II receiver will enjoy reading this interview with Mike of Pantronix. Here’s a short excerpt taken from DRMNA.info:

[DRMNA] Can you tell us a little about the process taken to develop the new receiver?

[Mike] We became aware of the need for a digital capable receiver by a visit from TWR representatives about three years ago. Having designed RF products and receivers in the past, it intrigued me that there were no low cost method to receive DRM. This began research into the problem. Initially we envisioned and designed what we call an ATU (Antenna Tuner Unit) that plugged into a ‘standard’ Android tablet. Unfortunately as time and testing proved, ready made tablets had varying problems from vendor to vendor, model to model. The decision was made about a year ago that we had to do our own Android ‘tablet’ and integrate the ATU into it. Hence the Titus II was developed.[…]
