Re: Advanced Receiver Research MSP144VDG-160 mast mount cover removal question

AMSAT-BB comes through again! Thanks to everyone for chiming in with encouragement to be a bit more enthusiastic with cover removal. I got a last minute request to use this preamp after US East Coast close of business on Friday, so I figured I would ask here first. This preamp was used to support some kids in their weather balloon experiments on Saturday, and through a complicated series of events far too difficult to explain required a ridiculously long coax run. Advanced Receiver Research has historically taken good care of me, including building custom preamps on short notice to support the WB4APR's NO-60 satellite mission. de KM1P

We are very fortunate to have access to MANY sources of information here. I do not watch ABC, CBC, CNN (or its groups of channels) or NBC to get news - I choose other News services . Likewise I dont really like much "social media" sites. I have not had a Twitter account, but due to the changes, I will more than likely be getting one this week. But those I dont like, I simply dont watch. AND believe it or not, there are some aspects of amateur radio that are simply not my cup of tea - so I dont do them. I know not all hams are into listening to satellites or ISS, but that IS my cup of tea. Find your "cup of tea" and focus on that.

It’s the same product with the addition of Bluetooth. RFinder bought the design from Portable Rotation, which had discontinued it.

Can you run an AC rotor on an small inverter? Maybe a true sine inverter. Or would the inverter be too electrically noisy?I also wonder if a brushed DC motor would be noisy too. Right up there with the antennas.Maybe they use a brushless or stepper motor. ???

I have begun building a 12vdc Az /El rotor for portable operation. The target use is moving lightweight EME antennas. The rotor has good torque and accurate incremental encoders mounted directly to each rotation axis. The rotor is slow but still fast enough to track the ISS. The rotor weighs 16 lbs. I don’t provide a controller but I list several compatible controllers including the open source K3NG controller.

The satellite will be equipped with a 24/7 digipeater on two different bands, as well as experimental SSDV transmissions. The satellite also has an education and outreach mission in that it is planned to involve Slovak grammar and high schools and to transmit special CW and AX.25 messages on several special occasions. From a platform perspective, the satellite will be equipped with a novel ADCS subsystem, including electromagnetic actuators and a GNSS receiver. This will also help to identify the satellite during the first days and weeks. The satellite will communicate o using Spacemanic's well-known Murgas transceivers (BDSat-1, BDSat-2, Planetum-1). Altogether, Veronika will provide: AX.25 telemetry; a CW beacon; a digipeater; AX.25 & CW messages on special occasions for community engagement; Experimental SSDV transmissions; and SATNOGS integration, decoder and dashboard. A downlink on 436.680 MHz has been coordinated and will use 9k6 G3RUH AX.25 and a CW beacon. Planning a SpaceX launch on Transporter 9 mission in Q4 2023 to a 500/600km polar orbit .

Its primary mission is to act as a digital amateur radio repeater. Its secondary mission is to transmit low-resolution SSDV images in a GFSK Mode. The tertiary mission is to transmit a CW beacon that will help amateur radio operators detect the presence of the satellite and measure basic properties of the signals such as its strength, fading due to spin, Doppler to measure speed, etc. A downlink on 436.235 MHz has been coordinated for 20 wpm CW, 500bps GFSK telemetry and 5kbps GFSK SSDV.

The triple-core rocket lifted off from Kennedy Space Center's pad 39A with the Jupiter 3/EchoStar 24 satellite at 11:04 p.m. EDT. The booster carried EchoStar's Jupiter-3 (EchoStar-24) communications satellite, which weighs in at over 9,000 kg (198,416 lb.). It is the largest communication satellite ever launched to geostationary orbit. Jupiter-3, which was built by Maxar Technologies, will support Internet connectivity across North and South America, in-flight Wi-Fi, community Wi-Fi services, maritime connections, enterprise networks, and backhaul for mobile network operators.

NASA's long-running Voyager 2 mission, which launched from Earth in 1977 and is currently about 12.4 billion miles from Earth, lost contact with our planet after a set of commands accidentally moved Voyager 2's antenna two degrees away from Earth on July 28. A "heartbeat" signal was picked up on Tuesday, August 1. according to NASA's Jet Propulsion Laboratory (JPL), letting mission controllers know the probe was still healthy despite being unable to communicate fully with it. Voyager 2 is programmed to automatically reset its orientation a few times a year in case of troubles like this, but the next window would have been in October. On Friday, August 4, JPL announced in a mission update that NASA's Deep Space Network facility in Canberra, Australia was able to send a command into interstellar space that reoriented the spacecraft and pointed its antenna back towards Earth. Mission controllers had to wait 37 hours to learn if the command was successful. And it was. "The spacecraft began returning science and telemetry data, indicating it is operating normally and that it remains on its expected trajectory," JPL said in the statement. [ANS thanks space.com for the above information.] + The ISS briefly lost communication with ground control due to a power outage at Johnson Space Center and had to use its backup control systems for the first time. A power outage at NASA's building in Houston disrupted communication between mission control and the International Space Station (ISS) on Tuesday, July 25. Space station program manager Joel Montalbano said neither the astronauts nor station were ever in any danger and that backup control systems took over to restore normal communications within 90 minutes. "It wasn't an issue on board. That was purely a ground problem," he said. "At no time was the crew or the vehicle in any danger."

Would explain why the product photo looked exactly the same Peter.

That is interesting. How does the cost compare to that other company who used to sell portable 12v rotor?
