Here is the inventor with a huge loop antenna designed for LOWFER's texting communications. A
new hobby is about to emerge in LOWFER's communications. This is greatly recommended for people living under a rock during "hard times" and finding shelter and communicating with the world.


There was an article on the net I found that would be good for a great achievement is survival communications. A 16 year old teenager at Feb 1, 2010 has invented a longwave radio transmitter that uses texting technology that is powered by some kind of, maybe a potato or 4 AA batteries that uses a radio transmitter and receiver that is possibly set on 160 kHz to 190 kHz LOWFERS band. It's a neat concept that the project he did was very basic, but there is no schematic diagram for this. Many hams and hobbyists will start designing a 2 way texting circuit and digital voice communication device to use in caves and in RF underground attenuated areas that MF, HF, VHF, and UHF communications cannot go through rock and debris.

The computer he used is probably something very basic that is takes text pulses to analog signal, but since this communications was very basic, no encryption was used in the experiment. This communication might replace plain old voice communications and morse code (CW). Soon there will be a kit an d antenna for this operating in the LOWFER's band while other communication will be implemented on lower frequencies.

Here is the down fall for this, First it's an invention, an invention that just shows that digital signals using long wave frequencies can be sent and received under a huge rock. There is no schematic diagram, no block diagram, 16 year old was just experimenting, but is or is not going all out to release the "blue" prints of the project to anybody. He won 1st prize, a new computer with Windows 7, and $12,000

What I have read he used a algorithm in basic programming to intercept digital signals from noise mostly like PSK31 digital mode in electromagnetic noise. The range could be 30 kHz to 190 kHz or 1 kHz to 30 kHz. But his loop antenna looks like it's a Lowfers type of antenna. They had to put the antenna together, get the turning the wire around the loop right, but it was not that hard connect it to the transmitter and fine tune it.

When the crew tuned up the antenna and the 2 way communications or likely 1 way communication device, his father was the receiver of the 1st digital cave text message "appy" which means happy in abbreviation via long wave that is when was documented and logged.

We are hoping that he will share this with hobbyists around the world as the time comes. It's only the middle of the road of digital long wave communications. Soon there will be endless possibilities for this earth to underground communication using sophisticated radio communications equipment. Long wave radio is a great way to communicate under a rock even in the rubble not all transceivers have to be high powered to achieve far distances. This communication could be used in small wrist watches since they are able to receive WWVB from Fort Collins CO on 60 kHz, and some claim that it may work in subway and underground areas where there is no cell phone towers. AM digital long wave radio is possible for HD radio national broadcasting, but since the bandwidth is limited, transmitters have to spread apart far from each other and not interfere with existing longwave broadcasters of the world from 150 kHz to 290 kHz. If NDB goes all digital then broadcasting will be possible on the LW bands just it was in Europe, Asia, and North Africa Back to the 2 way communcations, this theory and idea would be helpful, but will be kept for future reference. And also save lifes underground. There are various projects out there and if you know about L/C tuning circuits you could build a long wave transmitter for 160 kHz to 190 kHz.
