qo-100 POTA more MX0MXO portable in the part / Bob makes his first qo-100 contact

Saturday, 7 May 2022

MX0MXO was portable in Laleham Park working satellites and HF

 

Base camp for the night, HF, VHF and UHF

Boby this is not the way to detect RF current



Good to speak to Simon on XW2A satellite from the park

K3WW on 15 meters


 

Radio Romania International (SWL)

And the Europeans are active e on 14Mhz 20 meters giving away points for @arrl contest

First time using @Icom_UK 9300 built in RTTY doing a good job on 7Mhz / 40 meters

21Mhz full of US stations @arrl contest great to work so many over the weekend

Chertsey out portable in the park, Peru on 20 meters and several Satellite contcts



 

MX0MXO portable laleham park

Last night out in the park again. Best contact Peru on 20 meters, Big French contest on all bands, lots of points given away. Satellites XW-2A and RS-44 into Spain too. Can't complain good evening.

prepare for ISS Xband repeater carnage

 




Current Status of ISS Stations

as of Feb 17, 2022
​Columbus Module radios:
  • IORS (Kenwood D710GA) – STATUS - ConfiguredCurrent mode set to cross band repeater (145.990 MHz up {PL 67} & 437.800 MHz down).  Next mode change to support packet operation (145.825 MHz up & down) is currently TBD.​​
    • Radio will be used for ARISS Digital SSTV experiment on Feb 20 from 05:00 UTC until 12:00 UTC while ISS is in range of Europe. Please give a clear channel.


ARISS Europe to Perform Special Digital SSTV Experiment

Amateur Radio on the International Space Station (ARISS) is planning for a special SSTV experiment. ARISS is the group that puts together special amateur radio contacts between students around the globe and crew members with ham radio licenses on the International Space Station (ISS) and develops and operates the amateur radio equipment on ISS.

As part of its ARISS 2.0 initiative, the ARISS International team is expanding its educational and life-long learning opportunities for youth and ham radio operators around the world.  ARISS Slow Scan Television (SSTV), which is the transmission of images from ISS using amateur radio, is a very popular ARISS mode of operation.  To expand ARISS SSTV capabilities, the ARISS Europe and ARISS USA teams plan to perform special SSTV Experiments using a new SSTV digital coding scheme. For the signal reception, the software "KG-STV" is required, as available on internet.
We kindly request that the amateur radio community refrain from the use of the voice repeater thin this SSTV experiment on 20th of February 2022 over Europe.

 
This is a unique and official ARISS experiment. We kindly request keeping the voice repeater uplink free from other voice transmissions during the experiment time period.  Also note that ARISS is temporarily employing the voice repeater to expedite these experiments and make a more permanent, more expansive SSTV capability fully operational on other downlink frequencies.
The first experiment in the series will utilize ARISS approved ground stations in Europe that will transmit these digital SSTV signals.  These will be available for all in the ISS footprint when SSTV transmissions occur.  The first SSTV experiment is planned for 20 February 2022 between 05:10 UTC and 12:00 UTC for five ISS passes over Europe.  Please be aware that this event depends on ARISS IORS radio availabilities and ISS crew support, so last-minute changes may occur.


To promote quick experimental SSTV investigations—to learn and improve--the ARISS team will employ the ISS Kenwood radio in its cross-band repeater mode.  The crossband repeater operates on a downlink of 437.800 MHz.  Each transmission sequence will consist of 1:40 minute transmission, followed by 1:20 minute pause and will be repeated several times within an ISS pass over Europe. 
The used modulation is MSK w/o error correction. For the decoding of the 320 x 240 px image, the software KG-STV is required.  The KG-STV software can be downloaded from the following link: "http://amsat-nl.org/wordpress/wp-content/uploads/2022/02/kgstv_ISS.zip"
The ZIP file contains the KG-STV program, an installation and setup manual, some images and MP3 audio samples for your first tests as well as links for additional technical information about the KG-STV use.
The members of the ham radio community youth and the public are invited to receive and decode these special SSTV signals.
Experiment reports are welcome and should be uploaded to "sstvtest@amsat-on.be"
More information will be available on the AMSAT-NL.org web page: "https://amsat-nl.org/?page_id=568"
