434 MHz balloon launch from Goonhilly

søn, 08/07/2018 - 13:23
Goonhilly GHY-1 "Arthur"

Goonhilly GHY-1 “Arthur”

Phil M0DNY is planning to launch a high altitude balloon or two on Tuesday, July 10 from the Goonhilly Earth Station on the Lizard in Cornwall, nearby to the Marconi Wireless Testing Station.

Any help with tracking would be greatly appreciated!

We’re currently undecided between morning or late-afternoon. If we go for morning then we may also launch a second later near-identical balloon later in the day. 5m/s ascent, ~35km burst.

Two Trackers:

• Callsign: 1900 (year of construction of the Marconi Wireless Station)
– Calling Beacon: 433.650MHz.100 LoRa Mode 5
– Telemetry: 434.300 MHz LoRa 20.8K SF10 4/5 Explicit

• Callsign: 1901 (year of first over-the-horizon transmission received at the Wireless Station, from the Isle of Wight)
– 434.100 MHz USB RTTY 50bd 7n2 480Hz

I’ll post updates in #highaltitude on the day when I can.

For tuning in on the pi-in-the-sky LoRa gateway, the config you need is:

CallingTimeout=60
frequency_<x>=433.650
mode_<x>=5
AFC_<x>=y

Thanks, Phil M0DNY

The 434.100 MHz FSK RTTY balloon signal should be receivable across most of the British Isles using a radio capable of SSB reception in 434 MHz. Online tracking at https://tracker.habhub.org/

No radio? Use the SUWS online radio to receive signals from 434 MHz High Altitude Balloons when they are range of London (select USB mode) http://farnham-sdr.com/

Receive SSTV from Space June 29-July 1

ARISS Russia is planning a special Slow Scan Television (SSTV) event  from the International Space Station Station around 09:00 GMT on Friday, June 29 and continuing until 18:30 GMT Sunday, July 1.

Supporting this event is a computer on the ISS Russian Segment, which stores images that are then transmitted to Earth using amateur radio, specifically the onboard Kenwood TM-D710E transceiver.

These images will commemorate the various satellites that were hand-deployed from the ISS. These will include the first satellite deployment from ISS: Suitsat-1/Radioskaf-1 which was developed by ARISS and deployed in February 2006.

The transmissions will be made on 145.800 MHz FM using the PD-120 SSTV mode.

Note the ISS transmissions use the 5 kHz deviation FM standard rather than the narrow 2.5 kHz used in Europe. If your transceiver has selectable FM filters try using the wider filter. Handheld transceivers generally have a single wide filter fitted as standard and you should get good results outdoors using just a 1/4 wave whip antenna.

The ISS Fan Club site will show you when the space station is in range http://www.issfanclub.com/

ISS SSTV information and links at https://amsat-uk.org/beginners/iss-sstv/

Post your images on the ARISS-SSTV gallery at http://www.spaceflightsoftware.com/ARISS_SSTV/

If you don’t have an amateur radio receiver you can still listen to the ISS by using an Online Radio, also known as a WebSDR. Select a Frequency of 145800.0 kHz and Mode FM:
• Farnham WebSDR when ISS is in range of London http://farnham-sdr.com/
• R4UAB WebSDR when ISS is over Russia

Please note that the event is dependent on other activities, schedules and crew responsibilities on the ISS and subject to change at any time. You can check for updates regarding planned operation at:

ARISS-Russia FM transmissions from Space Station

tir, 19/06/2018 - 19:01

A Tanusha CubeSat

On June 20 and 21, the Tanusha satellites will be connected to an antenna on the ISS Russian Service Module and transmit voice messages on 437.050 MHz FM with 145.800 MHz FM relay.

The AMSAT-NA website says:

ARISS-Russia, in collaboration with the Southwest State University in Kursk, Russia, are developing a series of educational CubeSat satellites called Tanusha.

Two Tanusha CubeSats were developed by students at Southwest State University and were hand-deployed by cosmonauts during an August 2017 extravehicular activity. These two CubeSats are performing cluster flight experiments through communications links.

A second set of CubeSats, Tanusha 3 & 4 were launched earlier this year and are currently on-board ISS. Tanusha 3 & 4 are planned to be hand deployed by Cosmonauts in August. They will perform even more comprehensive cluster flight objectives than Tanusha 1 & 2.

On June 20, Tanusha 3 will be connected to one of the ARISS Service Module antennas and will transmit from 0730-1200 UTC on 437.05 MHz. These FM transmissions will include greetings from students in several languages, including Russian, English, Spanish and Chinese.

On June 21, Tanusha 4 will be connected to one of the ARISS Service Module antennas and will transmit from 0730-1200 UTC on the same frequency: 437.050 MHz.

The ARISS-Russia team plan to also retransmit these signals on the standard ARISS 2-meter downlink, 145.80 MHz using the JVC Kenwood D700 radio that is still on-board ISS. All are invited to listen to the CubeSats from ISS on 437.050 and/or 145.800 MHz FM.

Note: the Doppler shift for the 437.050 MHz signal will be +/-10 kHz.

In episode 21 of the TX Factor show Bob McCreadie G0FGX and Mike Marsh G1IAR discuss the linear (SSB/CW) amateur radio satellites and give a demonstration with the CAMSAT XW-2F satellite.

They also review the new Icom IC-7610 transceiver, and look at programming your SDR handie and running a SharkRF openSPOT digital radio IP gateway.

As always, in their free-to-enter draw, there’s a chance to win two great amateur radio-related items – a Prism dust cover for your rig, and a copy of the book “Amsats and HamSats”.

Bob and Mike discuss satellites near the start of the show and towards the end at 48:08 they give a live demonstration of the CAMSAT XW-2F SSB transponder satellite.

Bulgarian CubeSat EnduroSat on ISS awaiting deployment

EnduroSat One

EnduroSat One

Bulgaria’s first CubeSat, EnduroSat One, was launched to the International Space Station on the cargo resupply OA-9 mission on May 21, 2018 from the Mid-Atlantic Regional Spaceport in Virginia, USA. On May 24 the Cygnus capsule docked to the Station and the satellite was taken onboard the ISS.

The satellite will be deployed from the ISS in the coming weeks.

The mission aims to popularize the Radio Amateur activities in Bulgaria and it will include cooperation with Bulgarian Federation of Radio Amateurs (BFRA), including workshops and additional educational activities.

The spacecraft has been completely build in Bulgaria. This first educational mission aims to inspire young Bulgarians and give them the chance to participate in a real space program!

The Space Challenges and EnduroSat teams have invested considerable resources, time and effort in preparing the Bulgarian CubeSat. In order to support the Radio Amateur community, the satellite emits in frequencies which are readily available for receiving by anyone with basic communication skills and radio equipment.

It is hoped the mission will help more young Bulgarians learn the basics of satellite communications through practical exercises empowered by the orbiting satellite.

Radio amateurs from around the Globe will be able to listen to the satellite beacon and to receive telemetry data from the satellite on a regular basis. They will be able to connect to the satellite, receive detailed telemetry information and receive a confirmation from the satellite for every established connection which will serve as QSL card.

Beacon: 437.050 MHz CW and 9600 bps GMSK AX.25

IARU R1 highlights threat to higher ham radio bands

man, 28/05/2018 - 12:35

In issue 77 of the free IARU Region 1 VHF newsletter the Chair of VHF-UHF-uW committee Jacques Verleijen ON4AVJ highlights the threats to vital amateur radio spectrum at VHF, UHF and Microwaves.

In less than a year we will have our interim meeting about the use of the spectrum above 30 MHz. We have to face some challenges. I want to invite all Member Societies to think about how to promote, defend and use our frequencies.

They are wanted by others, both government and commercial, users. So this is a wake-up call to be aware that if we not are using those bands we will lose them. Such a setback will not be the responsibility of IARU(R1), if we lose them, but from the amateur community who often have more commitment to HF, than VHF&up.

I know that this statement will shock some of you, but it is true. Our survey on the use of VHF&up made this clear. So I want to invite all Member Societies to think creatively (out of the box, as we say now) to think how to improve activity on our dear bands.

Like some have said: “use them or lose them” and “HF is not the only bands for ham radio, but they are the easiest to use”.
