Dollar-for-Dollar Match on your ARISS Donation Thru June 17, 2019
During the ARISS Forum at the Hamvention, it was announced, that between now and June 17, that an anonymous donor will equally match one dollar for each dollar donated up to $10,000.
Here is an excellent opportunity to get the most from your donations to the ARISS FundRazr. The FundRazr Project was initiated to raise $150,000 towards the ARISS Radio Upgrade on ISS. To date 90 contributors have donated $24,840 to the campaign, about 17% of the goal. $10,000 of your dollars, donated now, will raise that total to $44,840, including the matching funds. It would be great if we could actually achieve one-third of our goal ($50,000) by mid-June. Please donate today at https://fundrazr.com/arissnextgen?ref=ab_6ruVeeeNzOa6ruVeeeNzOa

AMSAT Field Day on the Satellites
The weekend of June 22-23, 2019 is Field Day! Each year the Ameri- can Radio Relay League (ARRL) sponsors Field Day. The Radio Amateur Satellite Corporation (AMSAT) promotes our own version of Field Day focused on operation via the amateur satellites, held concurrently with the ARRL event.
The AMSAT Field Day 2019 event is open to all Amateur Radio opera- tors. Amateurs are to use the exchange as specified in ARRL rules for Field Day. The AMSAT competition is to encourage the use of all amateur satellites, both analog and digital.
The congestion on FM LEO satellites is always so intense that we must continue to limit their use to one-QSO-per-FM-satellite. This includes the International Space Station. You will be allowed one QSO if the ISS is operating Voice.

Lightsail-2 Scheduled for Launch June 22 - Beacon on 437.025 MHz
LightSail is a citizen-funded project from The Planetary Society. This cubesat will be propelled solely by sunlight, to Earth orbit. LightSail 2 is scheduled to launch aboard a SpaceX Falcon Heavy on June 22, 2019, and we will attempt the first, controlled solar sail flight in Earth orbit.
LightSail 2 will ride to space aboard the Department of Defense Space Test Program-2 (STP-2) mission which will send 24 spacecraft to 3 different orbits. LightSail 2 itself will be enclosed within Prox-1, a Georgia Tech-designed spacecraft originally built to demon- strate close-encounter operations with other spacecraft. Prox-1 will deploy LightSail 2 seven days after launch.
After a few days of health and status checks, LightSail 2's four dual-sided solar panels will swing open. Roughly a day later, four metallic booms will unfurl four triangular Mylar sails from storage. The sails, which have a combined area of 32 square meters [344 square feet], will turn towards the sun for half of each orbit, giving the spacecraft a tiny push no stronger than the weight of a paperclip. For about a month after sail deployment, this continual thrust should raise LightSail 2's orbit by a measurable amount.
LightSail 2 will fly in a 24-degree inclination, 720 km, circular orbit. At latitudes of 42 degrees north it will reach a maximum elevation of 10 degrees above the horizon.
Lightsail-2 has been issued an experimental radio license WM9XPA and transmit on 437.025 MHz. A morse beacon will transmit the callsign every 45 seconds. A packet beacon will transmit AX.25, FSK 9K6 bps data. Beacon information is available at: http://tinyurl.com/ANS-153-Lightsail-Morse-Beacon Documentation of the downlink telemetry data structure is posted at: http://tinyurl.com/ANS-153-Lightsail-Telemetry

AMSAT-EA FossaSat-1 Receives IARU Coordination
The IARU reported that AMSAT-EA FossaSat-1 satellite has received a downlink coordination to operate on 436.700 MHz with LoRa 125kHz, Chirp Spread Spectrum Modulation, 180 bps, 100mW; and, FSK RTTY 45 baud ITA2, 100mW 183hz Shift.
The planned mission objectives for the 5x5x5cm 250gram satellite are:
+ General development of miniaturized and inexpensive satellite systems for space applications using off the shelf components.
+ Testing a new solar panel mechanism, making this satellite the smallest to have deployable solar arrays. These solar arrays will additionally increase the radar reflectivity significantly to that of a standard cubesat.
+ The promotion & involvement of students in aerospace development on an international level, giving them the opportunity to test their hardware and software experiments on the satellite. AMSAT-EA will be hosting STEM workshops & competitions for secondary stu- dents to participate in, a full section of the satellite is dedi- cated to these experiments for educational research.
+ The main mission of the satellite is the testing of a new experi- mental RF chirp modulation called LoRa, this new modulation hugely increases the link budget, reduces the power consumed and reduces the cost of receivers.
Students & Amateurs will be able to receive telemetry from the satel- lite with inexpensive hardware, expanding & promoting the amateur satellite community among youth.
Uplink challenges will also be carried out with rewards for amateurs. AMSAT-EA will provide decoding software for SDR use in order to allow anyone to decode LoRa using common existing hardware & host software for users to submit telemetry data, making all data public and reward- ing users with certificates & awards.

Send Your Name (and callsign) to Mars NASA Press Release May 21, 2019
NASA is giving the public an opportunity to send their names — etched on microchips — to the Red Planet with NASA's Mars 2020 rover, which represents the initial leg of humanity’s first round trip to another planet. The rover is scheduled to launch as early as July 2020, with the spacecraft expected to touch down on Mars in February 2021.
The opportunity to send your name to Mars comes with a souvenir board- ing pass and "frequent flyer" points. From now until Sept. 30, you can add your name to the list and obtain a souvenir boarding pass to Mars here: https://go.nasa.gov/Mars2020Pass
The Microdevices Laboratory at NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California, will use an electron beam to etch the submit- ted names onto a silicon chip with lines of text smaller than one- thousandth the width of a human hair (75 nanometers). At that size, more than a million names can be inscribed on a single dime-size microchip. The chip (or chips) will ride on the rover under a glass cover.

RS-10 Downlink Provides Unique Troubleshooting Solution
Terry Osborne, ZL2BAC, recalls a troubleshooting solution utilizing the downlink from the RS-10 satellite as he was resolving an HF noise problem in the radio system of New Zealand's Maritime Radio Network. (http://tinyurl.com/ANS-153-NZ-Maritime-Radio)
The New Zealand network consists of a chain of VHF base stations, an HF Transmitter site and an HF Receiving site. These are all linked back to an Operations Centre in Lower Hutt (near Wellington).
During commissioning, Terry was visiting the Operations Centre where the operators mentioned that the HF receivers were very noisy. This didn't sound right since the receiving site had been chosen because it was in a remote area well away from any man made noise.
Terry said, "To check how well the receivers were working I gave the operators the frequency and a week of pass times for RS-10. This was on a Friday. On Saturday I turned on my receiver at home on RS-10. My receiver was a TenTec Argonaut 505 with DGFet preamp and a half wave dipole at about 10 feet. RS-10's downlink boomed in at about 5x7. The Maritime operators heard nothing on their receivers. I fed the audio down the phone line to convince them it was working."
The four HF receivers are fed from a Multicoupler that has a "Low Noise" amplifier feeding a splitter. On the following Monday, the technicians from the maintenance base visited the site and at AOS of RS-10, turned off the power supply to the multicoupler. The Oper- ations Centre reported down went the HF noise and up came the signal from RS-10.
Terry reported on the solution, "There were many options for the 'Low Noise' amplifier in the multicoupler ranging from a 2dB noise figure 10 dB gain version up to a 30dB gain 15dB noise figure version. Upon removing the lid from the multicoupler it revealed that the 30dB gain 15dB noise figure version had been supplied rather than the 2dB noise figure 10dB gainversion specified. It turned out that the manufacturers of the Multicoupler hadn't actually made one with a 2dB NF/10dB Gain amp before and had just supplied their standard version. Putting in the right amplifier solved the problem."
In closing, Terry wrote, "Satellite operators who have worked with preamps will recognise this problem."
