Proxies | Free Public Proxy List. Amateur Radio Website - Nightly. Galaxy SIII Robust Communications - Nightly. This page is written for people using the Samsung Galaxy SIII mobile phone who would like enhanced privacy, unblocked internet, and the ability to communicate without normal mobile telephony infrastructure. If you happen to dislike the stock software installed by the manufacturer or local vendors, you can change the system to a customized version that is more suitable. Concerned about surveillance "backdoors" in phones sold in countries with oppressive governments? Erase the phone's software and replace it with a trustworthy and high performance system featuring the best encryption, SMS, and telephony applications! This guide focuses on the Galaxy SIII GSM phone, but the method is applicable to other Android phones or tablet computers.
CAUTION and DISCLAIMER: Unlocking / Rooting the Galaxy SIII will erase your present settings, pictures, music, contacts, and applications! It is most convenient to root the phone immediately after purchase - before large amounts of data are saved. OpenVPN Cloaking - Nightly. An Effective Defense Against Deep Packet Inspection Given here are two methods of maintaining OpenVPN service against filtering attacks by governments opposed to anonymity, security, and freedom of access on the internet. Both methods have come about due to the deployment of advanced surveillance technologiy, known as "deep packet inspection (DPI)," which identifies and enables blocking of VPN connections. OpenVPN connections are high priority targets due to the protocol's speed, security, and high popularity among internet users.
Stunnel and Obfsproxy both conceal the VPN packets within an encrypted shell and make them resistant to deep packet inspection "find and block" activities. Note: The instructions given here for cloaking OpenVPN with Stunnel or Obfsproxy were accomplished on a system running Debian Sid Gnu/Linux. Configuring an OpenVPN System for Stunnel Stunnel will sit between the server and the internet. Stunnel on the OpenVPN Server Install Stunnel: apt-get install stunnel4. Galaxy Nexus Robust Communications.

Why NASA Created the Apollo Unified S Band System Launch, in-space operation, and re-entry, of any spacecraft require tightly coordinated actions on the ground and on the spacecraft. Information must be passed both ways, and use radio links to accomplish it all. Voice communications connect the people involved: covering the moment to moment status of the flight, experiences and decision making that are part of manned spaceflight.
Data communications carry data from spacecraft elctrical, guidance, life support, and other systems back to earth, while comand and control data are sent to the spacecraft for the purpose of updating spacecraft systems with essential data, configuring the spacecraft apropriately for its phase of flight, and accomplishing various tasks that are impractical or unsafe for astronauts to attempt. The Mercury and Gemini programs, used a growing kludge of radio systems on VHF and UHF for voice and telemetry. Signal Characteristics Non - Unified S Band System Signals. MOFO Linux. Have you grown tired of being muzzled by your internet service provider - not allowed to visit websites for political reasons? Are you in an oppressive country that blocks your access to free and open discussion of important social issues? Would you like to use computers at public internet cafes without being subject to internet filters, surveillance, spyware, or malware? Would you like to use your own operating system on public computers and leave no usage tracks and block surveillance of your activities?
If yes, then "MOFO Linux" is your solution. MOFO Linux is secure, free (as in freedom and beer), and effective in penetrating "national firewalls" designed to inhibit freedom of speech. Download MOFO Linux version 2.0: MD5SUM: dd431c88b5d4d7aac84c632660611d92 SHA1 : 97c2b460961a8a974473665097d1bb8ba8e13f37 MOFO Linux is a specialized version of Porteus Linux, designed for overcoming internet filtering and surveillance imposed by service providers, governments, or other entities.
High Gain Air Band Antennas. Many radio hobbyists monitor the VHF air band and are satisfied with the results using discone or vertical antennas. For local and moderate distances, such antennas will deliver signals well above the noise level. If one has an interest in distant or low altitude aircraft, basic air band antennas are not satisfactory. Weak signal air band reception requires a combination of optimized antennas, low loss feedlines, and mast-mounted preamplification.
Preamplifiers should not be the first choice for air band signal enhancement, because the gain often comes at the sacrifice of bandwidth and dynamic range. At best, a well made filter and low noise preamplifier combination will improve the station noise figure and provide high gain over a 2 to 3 MHz bandwidth, and reject out of band signals.
Strong signals in the passband may cause desensitization or intermodulation problems in the receiver. A better solution is to install a high gain antenna and use the best possible low loss feedline. Long Range Wi-fi Dish Antenna. Presented here is a project showing how to convert common satellite TV antennas into high performance wi-fi dish antennas. If you intend to make multi kilometer wi-fi connections, this is the antenna type to use. With a high power wi fi adapter this kind of antenna is fantastic. Such a large 2 or 3 meter diameter wi-fi dish can provide 802.11 connections to access points dozens of kilometers away (if the path is line of sight). Satellite dishes are easy to convert into wi fi dish antennas.
The essential change is replacing the satellite TV feedhorn with a modest directional wi fi antenna. Obtain a parabolic reflector designed for C or Ku band satellite television service. Satellite TV reflector + WiFi antenna = LONG range connections! For very long range wireless networking, I have used a short 5 turn version of the helical wi-fi antenna, left hand polarized, with an 80 cm parabolic reflector. Installing a wi fi dish antenna is more complex than it seems. High Gain Yagi Wi-Fi Antenna. Build this wi-fi antenna to build when you want results FAST and have just a few inexpensive tools and supplies available. It will greatly extend your wi-fi range - well beyond the limits of the dipoles that accompany most routers and some wireless adapters. When connected to a USB wireless adapter the performance is excellent. When connected to a high powered wi-fi adapter, the performance is astounding!
Forget about building those overly hyped wi-fi cantennas - they don't perform anywhere close to the yagi antennas depicted here. Read more below for instructions and a narrative of how they were designed. The yagi wi-fi antenna design depicted here can be built in just an hour or two, and it works great! It is computer designed, made of wood and wire, and provides high gain and directivity.
Yagi wi-fi antennas can be rather difficult to build, but it can be done if you measure precisely and cut precisely. Print and use this plan view when building the 15 element yagi wi-fi antenna.
Getting started. High Gain Wi-fi Helical Antenna. Protect yourselves with: Anonymous Email Presented here is a versatile, durable, and rather unique wi fi antenna that can greatly extend your wireless networking range and speed. When built with ten or more turns, this helical wi fi antenna vastly outperforms the cantennas and wi fi wok tops often seen on the internet. A short five turn helical makes a very good feeder for a wi fi parabolic dish antenna. A special quality of this antenna is that it radiates and receives a circularly polarized signal. It does not favor vertically or horizontally polarized signals. Thus, this antenna works well with wi fi signals reflecting off of buildings, moving vehicles, or antennas oriented at odd angles.
Circularly polarized signals are less affected by rain, so you can reach distant access points in stormy weather. Design parameters for this helical wi fi antenna were calculated using the online helical antenna calculator and was inspired by similar designs used for the AMSAT OSCAR 40 satellite.
