Is there an efficient and secure way to transmit bitcoins over shortwave radio?

1

Although I am not qualified enough to suggest a protocol for over-the-air, I can still get some technical pointers. You may want to ask at the ham radio SE community.

Yes you can easily send Bitcoins over shortwave radio using encryption but radio encryption is not a topic of this community. It's also severely illegal in the U.S. for a HAM operator to use any kind of encryption when transmitting.

The Bitcoin network over-the-air

This is what I think you are asking, the Bitcoin protocol does not send private keys of bitcoins around as its main technique as this is risky and dangerous inherently. The Bitcoin protocol moves bitcoin without the need to exchange private keys of any bitcoin so it be better to just implement the network over radio.

Bitcoin can practically be agnostic to the protocol you are using, as long as communication is possible Bitcoin will work. There are many protocols for shortwave radio available that can move data from a transmitter...

Shortwave radios were first developed in the early 20th century. What began as little more than an experiment ended up changing the way the world communicated. In 1920, almost all long-distance communication was conducted via transoceanic cables - but by 1928, shortwave radio communications had grown exponentially, accounting for more than 50% of long-distance communications.

Today, the popularity of shortwave radios has been largely reduced by invention of functional cell phones and the Internet, but the technology is still widely used around the world. Various international broadcasting organizations still use the technology, and shortwave radios are a staple of the survivalist community because of their ability to receive emergency transmissions over long distances.

So, what are shortwave radios, and how can you use them to your advantage? Technically speaking, a shortwave radio is a receiver that can receive radio transmission on frequencies up to 30 MHz,...

[This post on Bitcoin: Fake Asset or Security? was originally published on The Institutional Risk Analyst from R. Christopher Whalen.]

“I came of age on Wall Street when the Chairman of the Federal Reserve Board—he was William McChesney Martin — condemned even trace amounts of inflation as an economic and moral evil. In the interval of 1960-65, there was not one year in which the CPI registered a year over year rise of as much as 2%.”

Below is my latest commentary on housing finance reform in American Banker, “Fannie, Freddie are irrelevant to a government-backed mortgage system.” I’ll be participating at the CoreLogic Risk Summit next week in Dana Point, California. Come say hello!

We’ve all heard of fake news, but consider the growing possibility of fake or at least virtual assets. Investors face a deliberately orchestrated shortage of real investments c/o global central banks in markets such as stocks and real...

The vast majority of Bitcoin speculation occurs through long and short positions across trading platforms. Longing and shorting has been a more favorable solution for most national currencies and assets over the past few years. Bitcoin speculators rely on these same tools to guesstimate how the price will evolve in the coming hours, days, and weeks. Given the current BTC price trend, shorting Bitcoin becomes quite appealing. Below is a brief list of ways to short Bitcoin and – hopefully – make a profit while doing so.

#7 Bitcoin Margin Trading

One of the most common ways to short Bitcoin is by using a cryptocurrency margin trading platform. A lot of major Bitcoin exchanges give users this opportunity, albeit some specialized trading platforms are worth checking out. By using margin trading, one essentially “borrows” money from a broker to make a trade. Do keep in mind there is also a leverage factor, which can exponentially increase your profits – and losses.

A new project that transmits bitcoin payments over the radio is up and running in Finland – and it’s also transmitting a national Finnish cryptocurrency at the same time.

Kryptoradio is a data transmission protocol designed to transmit low-bandwidth information over one-way digital broadcast networks.

Joel Lehtonen, the project’s founder, said he is focused on using Kryptoradio to transmit block chain information. The project is currently halfway through a two-month pilot phase in conjunction with Finnish broadcaster Digita, which allows the system to transmit bitcoin transaction information across its digital radio network.

Bitcoins via radio

The project transmits the data over the DVB-T network, which is a digital audio and video broadcast network used by TV and radio broadcasters around the world.

Kryptoradio’s back-end computers connect to the block chain and turn the latest block’s transactions into a data stream. This is then...

To successfully manage your wireless network, you don’t need to understand all the details of signal processing. When sending data over radio frequencies (RF), however, remember these details:

A lot of other traffic is out there, as well as natural phenomena such as atmospheric disturbances and electrical storms (you have to love a good lightning storm) that can cause interference with these signals. Either data sent on the same frequencies or blocked signals can interfere with your wireless communications.

You need to modify a standard signal to transmit data. There are many standard methods to perform this task.

RF bands are only so wide and can therefore only handle so many discrete sessions or channels at a time. The entire FM radio spectrum has been broken up into 100kHz channels used to assign frequencies to radio stations. This means that there are only so many possible FM channels available for use.

Managing a wireless network does require...

Shortwave radio has been around since the early 20th century, but it is arguably still one of the most simple and effective means of communication around. With a shortwave radio, you can tune into international broadcasts, listen to AM/FM radio in remote locations using relays broadcasts, participate in the ham radio community, and pick up emergency broadcasts. Any one of these applications would make shortwave radio a worthy purchase. The fact that you can do all of this with just one device is incredible.

If you are thinking about buying a shortwave radio, but you are not sure where to start, the product comparison table below can help you out.

If you still are not sure what you need in a shortwave radio, read on to learn more about features as well as questions you should ask while shopping.

What is a Shortwave Radio?

A shortwave radio is a receiver which can pick up transmissions on frequencies up to 30 MHz, usually ranging between 1.6 and 30 MHz....
