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 to a receiver.As an interesting example, you could totally set up a node that communicated via Morse code as long as it has other nodes to talk to.You'd run into problems with bandwidth as some tx/rx modes are slow.You can possibly use a modified version of Bitcoin-qt and use the same handshakes and messaging it does over tcp/ip.The HAM radio community has interesting an P2P by itself which you can look into.APRS is a packet-based network which relies on peers to rebroadcast messages, it's really cool and is readily documented and has many tutorials.
They will anyway once it's in the blockchain.My best guess is this would not break the obscurity rule in the US.The rule I think that might be in play is not using amateur radio for commercial purposes.Buying an item through packet radio would most likely trigger this limitation.What I wonder, though, is if maybe it could be used to send some sort of humanitarian aid, for instance if one person with bitcoins does not have Internet access, and wishes to send money to someone who does, via radio.I can't think of a way a person could 'receive' bitcoin without being connected to the Internet (since receiving is really only recording the transaction in the blockchain) Your Answer Sign up or log in Sign up using Google Sign up using Email and Password Post as a guest Name Email discard By posting your answer, you agree to the privacy policy and terms of service.Browse other questions tagged protocol network offline-transactions or ask your own question.
Location: Topics: Field day.Upcoming topics (Subject to change): T.B.D.We needed to re-validate our Echolink account.When Echolink goes through the validation process it automatically issues you a new node number.The new node number is: 845553 The name still K2JJI-R, but if you need to connect via DTMF from a remote node, please use the new node number.Capacitive Touch morse code paddle using an ATTiny4 – (126 Bytes) Introduction: I (Edgar/KC2UEZ) am a ham radio operator.I like building antennas, experimenting with digital modes, and operating SDRs.Like many no-code operators, after being on the air for a while, I developed an interest and appreciation for Morse Code.I started to learn CW by using http://LCWO.net.I purchased a cheap paddle, but I found the clicking noise a little bit annoying.At this moment, I decided that I wanted to create a noise-free way to send Morse Code.While I was able to find a few touch paddles (without moving parts) that I could purchase, I ultimately decided to make my own.
I saw this project as an opportunity to do some hacking and to learn something new along the way.While researching capacitive touch online, I came across this Arduino playground post: http://playground.arduino.cc/Code/CapacitiveSensor.To get my project underway I modified the code to implement the paddle logic and loaded it into an Arduino.The code reads two input pins.If touch is detected by the micro-controller, the Arduino outputs two signals to toggle the transistors, which simulates a closed circuit, similar to that of a mechanical paddle.The closed circuit enables the radio to create the DIT and DAH tones.The under 1kB binary code worked well and without error.This made me wonder how small I could make this code.After optimizing the code, I managed to shrink it to under 512 bytes.Read more… Tryon ARC has created a list of suggested frequencies for the 2m band.Feel free to program these frequencies and use them.Those frequencies have good coverage for the Fulton and Montgomery counties.
If you have any corrections or have other frequency suggestions feel free to post it below or on our facebook page.The frequency list can also be found on the ARES/RACES page with the manuals for the radios FT2800 and IC718 which are the radios in the EOC radio room.The Tryon ARC would like to let all our members know about the NY QSO Party.Here is the bulletin sent by Dean, NW2K regarding this event: It’s all about NY on October 15 as radio amateurs from around the world get on the air to work all 62 NY counties, Chautauqua to Clinton, Niagara to Suffolk.A dozen or more mobile operators will take to the mean streets of NYC or the bucolic surrounds of the Southern Tier and North Country.Brave souls will sneak out to the woodlands to activate a rare county, Field Day style, as temps may dip into the 30’s.And good, solid Elmers will open up their shacks to new hams and build excitement as the spotlight is on US!Read more… Here is the net script to use on our monthly HF net.
