Ham Radio as a replacement for the Internet

My interest in HamSphere flows out of my concern for the future of the Internet. You may already be awareof some fairly dire predictions regarding the world economy and the loss of cheap oil. We are seeing the impacts of these emerging constraints now from bankrupt American cities to near record levels of unemployment to rising prices for basic essentials and the increasing US military action around the world.
I don't wish to debate the future here, rather I'd like to get your opinion on the feasability of using HamSphere as a replacement for the Internet should the need arrise. I know close to nothing about ham radio so please keep you comments simple enough for an 8-year old to understand. I'm happy to share what I know abouut Internet comunications but I suspect most folks are pretty familiar with it already. Thanks, - Deck Hazen |

Dear Deck Hazen,
I understand that the Hamsphere is working on internet and it is a simulated activity of HAM radio. It is a virtual HAM activity and no radio transmission goes on the air. If internet is not there then there is no hamsphere also. So hamsphere cannot be a replacement for the HAM radio. HAM radio is the most basic form of radio communication and it is a saviour when all other forms of communication fails. That is why HAMs have a greater role during the natural calamities, due to which the infrastructure for other types of communication would have got destroyed.

Hi Jayaraj,
You're quite right and I apologize for getting it wrong in the body of my message. As the subject of that post states (but is then contradicted in the body of the post) my interest is in using ham radio as a replacement for the internet. I was hoping for replies on the feasibility of such an effort - is it possible to send email (text) over a ham radio? Do ham users constitute a network? If I wanted to send a message to someone out of the range of my transmitter is it possible to send that message through another party that could then transmit the message to its intended recipient? Is it possible to send data with a ham radio? I know very close to nothing about radio technology (as must be evident) but I know a little about IP (Internet Protocol) and I'm sure there must be many in this group who know far more about both. I'd like to get some knowledgeable feed-back if anyone is interested. Thanks very much for the reply and the chance to once again raise the topic. -- Deck 57HS3941 Wrote: ------------------------------------------------------- > Dear Deck Hazen, > > I understand that the Hamsphere is working on > internet and it is a simulated activity of HAM > radio.

If yconnect at my Facebook timeline, you will see that I have been rather vigorously promoting the "hobby"!
Not onCan y would I bet my life onCall the radio, especially either 40 meter CW or packet radio in emergency, also if you are a students of the Bible there is this little thing called 666 ! Without it you may find keeping your ISP or Mobile phone company 's bill paid! It's always free to use amateur radio if you own your own equipment. By that time I doubt you will be greatly concerned about having a government license. You mentioned Packet Radio, it uses TCP-IP over amateur radio exclusively. Forget about Multimedia, the bandwidth is only suitable for text and still photos and uses ASCII and Binary to transfer data. It uses two tones around 1990-2100 hzjust like a phone modem (obsolete dial up connection ) And you can specify a "path" for digipeating or "connect" to a "Node" then connect to the city And then the stations there. Or you can send email .Examples; C LAX [return] C NYC [rereturn] then > C w1aw-7 [return ] in about 30 seconds you will receive ***connected to w1aw-7*** > now everything you type will be relayed to w1aw-7 by whatever paths are open and for x number of retries, depending on how you set that "parameter" it's fun if you want to see what goes on behind the scenes of TCP-IP. Like the internet, It's designed to survive local outage and acts of God. To send email over packet you must be connected to a "PBBS" Then just like gmail adressee ( ke6yb-3@n6gpp-5) or all@Ohio or all@usa or even an internet address like jimbo.ke6yb@gmail.com. The big thing today is APRS a different way of doing packet radio that is gateways to the Internet. I will let you check that out on your own. But remember it's NOT pure amateur radio. Reply if you have more questions. 73, Jim. |

Dear Deck,
You said "My interest in HamSphere flows out of my concern for the future of the Internet", the Internet is a distributed network of networks, there is no central point of failure. Its architecture was designed in order that if one part fails due to an attack information could simply be re-routed around the effected area and information could continue on as normal. The Internet will always be here, if lets say the electrical grid went down, you would start to see networks come back on line within days or weeks because hackers or technicians exist. The military are very well trained individuals, they would also have networks up and running asap for defence purposes. We have things like backup generators, the ability to transform solar energy from the sun into usable power for use in electrical devices. We have people working on free energy devices, we even have dynamo devices "The dynamo uses rotating coils of wire and magnetic fields to convert mechanical rotation into a pulsing direct electric current through Faraday's law of induction". See https://en.wikipedia.org/wiki/Dynamo#Rotary_converters. Lets not forget water power, wind power and nuclear power as well as the secret energy technology the Americans, British and Russians got from the Germans after world war 2. "You may already be awareof some fairly dire predictions regarding the world economy and the loss of cheap oil" you said. Those bankers, crooks, we need to remove the bankers out of the formula, companies should give people other options to be paid so we don't have to even use a bank if we don't want to. You said "We are seeing the impacts of these emerging constraints now from bankrupt American cities to near record levels of unemployment to rising prices for basic essentials and the increasing US military action around the world", the New World Order my friend, what the Bush family talked about or 666 as 2HS129 put it. "I don't wish to debate the future here, rather I'd like to get your opinion on the feasability of using HamSphere as a replacement for the Internet should the need arrise" you added. As mentioned Hamsphere works on top of TCP/IP using VOIP to simulate HAM radio, you corrected yourself with "my interest is in using ham radio as a replacement for the internet". You continued on asking multiple very important questions; 1) "is it possible to send email (text) over a ham radio?". 2) "Do ham users constitute a network?". 3) "If I wanted to send a message to someone out of the range of my transmitter is it possible to send that message through another party that could then transmit the message to its intended recipient?". 4) "Is it possible to send data with a ham radio?". I am not an expert, but I looked up your questions, the answer to your first question is yes. ASCII encoded data can be sent over amateur radio frequencies using homebuilt equipment, see https://en.wikipedia.org/wiki/Packet_radio#Amateur_Packet_Radio_and_the_AMPRNet and http://www.aprs.org/aprs-messaging.html. Also see morse code http://www.arrl.org/learning-morse-code. The answer to your second question is yes. Any group of people who communicate together constitute a network regardless of the medium they use to communicate. The answer to your third question is yes. "An amateur radio repeater is an electronic device that receives a weak or low-level amateur radio signal and retransmits it at a higher level or higher power, so that the signal can cover longer distances without degradation. Many repeaters are located on hilltops or on tall buildings as the higher location increases their coverage area, sometimes referred to as the radio horizon, or "footprint." Amateur radio repeaters are similar in concept to those used by public safety entities (police, fire department, etc.), businesses, government, military, and more. Amateur radio repeaters may even use commercially packaged repeater systems that have been adjusted to operate within amateur radio frequency bands, but more often amateur repeaters are assembled from receivers, transmitters, controllers, power supplies, antennas, and other components, from various sources" (Wikipedia, 2015). See https://en.wikipedia.org/wiki/Amateur_radio_repeater. The answer to your fourth question is yes. "Packet radio is a form of packet switching technology used to transmit digital data via radio or wireless communications links. It uses the same concepts of data transmission via Datagram that are fundamental to communications via the Internet, as opposed to the older techniques used by dedicated or switched circuits" (Wikipedia, 2015). See https://en.wikipedia.org/wiki/Packet_radio. You said "I know close to nothing about ham radio so please keep you comments simple enough for an 8-year old to understand", we are both in the same boat dear friend, hopefully the information above may shed a little light in dark places as it did for me. "I'm happy to share what I know abouut Internet comunications but I suspect most folks are pretty familiar with it already", you added. "HamSphere is a subscription-based internet service which simulates amateur radio communication using VOIP connections over the Internet. The simulator allows licensed radio amateurs and unlicensed enthusiasts to communicate with one another using a simulated ionosphere. It was designed by Kelly Lindman, a radio amateur with call sign 5B4AIT. The system allows realistic worldwide connections between amateur radio operators as well as radio enthusiasts. In general it is similar to other VoIP applications (such as Skype), but with the unique addition of characteristics such as channel selection by tuning, modulation, noise effects and shortwave propagation simulation" (Wikipedia, 2015). I hope the information provided may help in some way, I know very little about HAM currently but I am learning more and more by the day. Kind Regards, 26HS8638 Cerca Trova |
