General Overview

FREEnet (the network For Research, Education, and Engineering), a corporate noncommercial computer network, connects the academic and research computer networks of the Russian Academy of Sciences research institutes, universities, higher education institutions and other scientific, educational, and research organizations.

History

FREEnet was established on 20 June 1991 by N. D. Zelinsky Institute of Organic Chemistry (ZIOC) of the Russian Academy of Sciences (RAS) with the Network Operation Center at Computer Assistance to Chemical Research of RAS. In nineties, when research and educational community in fSU countries lacked the Internet services, FREEnet has developed infrastructure integrated 15 Russian regional RENs as well as some NRENs abroad. The total number of universities and research institution using FREEnet services at those time overcome 350. Later, in accordance with both academic community changing needs, and with general trends of Russian research and educational networking, FREEnet concentrated mostly on providing network infrastructure and advanced services, which users need especially for their research projects, rather than providing just basic Internet services.

FREEnet participated in numerous national and international projects, including those supported by the Ministry of Sciences, Russian Foundation for Basic Research, etc.

Services

Currently, FREEnet provides the following services to its users:

  1. High-speed Internet access via a dedicated line. Both IPv4 and IPv6 protocols are available on each access link. The choice of the protocol stack used is up to each user.
  2. Creation of fault-tolerant systems
  3. Remote management of the user's network infrastructure
  4. Traffic classification and assured forwarding services (Class Based QoS)
  5. VPNs over MPLS network infrastructure
  6. Collocation of user's equipment at FREEnet PoPs
  7. IPTV broadcasting over multicast IPv4 and routing of multicast streams among users.
  8. Dark fiber and L2 channels via Ethernet infrastructure.

Deutsche Technologies Rv3 Digital Satellite Finder Manual ((full)) File

The Deutsche Technologies RV3 is a digital satellite finder designed for mobile use, particularly in RVs and caravans. It is specifically pre-programmed for the Optus C1 satellite, making it ready for VAST and Foxtel systems in Australia. 1. Getting Started

Power On: Move the power switch to the "I" position. The meter takes roughly 6–7 seconds to boot to the main menu.

Initial Charging: For the first use, charge the 1950mAh Lithium-ion battery for approximately 8 hours. Standard subsequent charges take about 4 hours. 2. Setup and Wiring

LNB Connection: Connect a jumper cable from your satellite dish's LNB to the port labeled "LNB IN" on the meter.

Receiver Connection (Optional): If you are not using the internal battery, connect the cable from your satellite receiver to the "Receiver" port to provide power.

Signal Source: Ensure there is a clear line of sight to the sky, avoiding trees or buildings that may block the signal. 3. Aligning the Satellite Dish DIGITAL SATELLITE METER - Satking

The Deutsche Technologies RV3 Digital Satellite Finder is a high-definition meter designed for mobile users (caravans, RVs) to quickly align satellite dishes for services like VAST and Foxtel. It allows you to view actual channels on a built-in color screen to verify stability. Core Features & Specifications

is specialized for ease of use in remote areas with the following technical profile:

Display: 3.5-inch LCD color screen with live picture and sound. Frequency Range: 950MHz to 2150MHz. Battery: Rechargeable 1950mA Lithium-ion battery. deutsche technologies rv3 digital satellite finder manual

Measurement Tools: Reads Bit Error Rate (BER), Signal-to-Noise Ratio (SNR), and dBuV signal levels.

Smart Functions: Automatically calculates dish angles (Azimuth/Elevation) based on your GPS coordinates (Longitude/Latitude).

Auto-Calibration: Uniquely re-calibrates every time it boots up for maximum accuracy. Quick Setup Guide (Common Manual Steps)

Based on standard operation for this class of meter, follow these steps to align your dish:

Initial Connection: Connect your satellite dish LNB to the "LNB IN" port on the top of the meter using a coaxial jumper cable.

Power On: Press and hold the Power button for 2 seconds. The meter will self-calibrate upon startup. Satellite Selection: Navigate to the Satellite Finding menu.

Select the target satellite (typically Optus C1/D3 for Australian services). Dish Alignment:

Use the meter's calculated angle settings for your location. The Deutsche Technologies RV3 is a digital satellite

Slowly rotate the dish. The meter will provide an audio tone that increases in pitch as you get closer to the signal.

Fine-Tuning: Once locked, monitor the Signal Quality (Q) and BER bars. Adjust the LNB skew and dish elevation until these values are maximized on the screen.

Channel Verification: Exit to the main menu and select the Channel List or TV Channel to view the live broadcast, confirming the signal is correct. Included Accessories The unit typically ships with: Carrying case and neck strap. Both 240V mains and 12V cigarette lighter power chargers. AV cables for connecting to external screens. Using a SatFinder satellite meter to align your dish

The Deutsche Technologies RV3 Digital Satellite Finder is a signal alignment tool used to peak satellite signals by connecting between the LNB and the receiver. While specific scanned manuals for "Deutsche Technologies" can be difficult to locate, the RV3 follows the standard operational procedure for digital "Satfinder" meters. Standard Operating Procedures Connection Setup:

LNB Port: Connect a jumper cable from the satellite dish LNB to the port labeled "TO LNB" on the finder.

REC Port: Connect the cable coming from your satellite receiver to the port labeled "TO REC". The receiver must be powered on to provide the 13-18V DC required to light up the meter. Initial Configuration:

Power on your receiver and ensure it is set to the correct satellite and transponder. The RV3 display should light up once connected.

Adjust the sensitivity knob (if applicable) or use the buttons to set the signal level to roughly 20% or until the audio tone is steady but not peaking. Alignment & Peaking: Tips for Best Results

Azimuth (Left/Right): Slowly rotate the dish horizontally. When the meter shows a spike in signal strength or the pitch of the buzzer increases, you are near a satellite.

Elevation (Up/Down): Once a signal is found, adjust the vertical tilt of the dish to maximize the reading.

Attenuating: If the meter reaches 100% (full scale), use the control knob to reduce the level back down to 50% and continue fine-tuning until you reach the highest possible reading. Troubleshooting Tips

No Power: Check that the receiver is plugged in and the coaxial cable is securely connected to the "TO REC" port.

False Positive: If you have a high reading but no "Lock" on the TV, you may be pointing at the wrong satellite. Use a Satellite Finder App to verify the correct direction for your specific location.

Compass Interference: Ensure you are 4–6 feet away from the house or metal structures when using a physical compass for initial alignment.

Since physical manuals for specific budget-brand satellite meters are often brief or difficult to find, this guide compiles the standard operational procedures, specifications, and troubleshooting steps specific to the RV3 model series.

Problem 3: Signal jumps erratically.

What the RV3 Does

The RV3 is a compact digital satellite finder that helps you align a satellite dish quickly by measuring signal strength and lock parameters. It supports DVB‑S/DVB‑S2 signals, displays signal strength and quality, and typically includes an LCD, audio tone, and a built‑in LNB power supply (13/18 V) with 22 kHz switching for single‑LNB or tone‑burst control.
