Transponder is only active during night passes and at weekends Passband may be up to 15 kHz higher depending on on-board temperaturesĮducational Telemetry beacon is 300 mW during day and 30 mW at night. Inverting SSB/CW transponder 300 mW PEP.145.935 MHz BPSK Telemetry 30 or 300 mW.Further information on the courses is available from the CARS Training Coordinator, Christopher G0IPU Richard took the amateur radio courses run by the Chelmsford Amateur Radio Society (CARS) at Danbury in Essex. Many thanks to everyone who attempts to track these. The dl-fldigi release can be found here: You’ll need dl-fldigi release 3.2 and slightly modified LoRa gateway, as explained on the site. Hence receivers should upload to instead, please read the instructions on this site. This is experimental, and doesn’t support it just yet.

Rather than the usual JPEG SSDV, this payload is transmitting Better Portable Graphics (BPG) images. Many thanks to Dave Akerman M0RPI for making his work on LoRa available for us to use, including the lora gateway. – 869.85 MHZ LoRa ‘Mode 3’ (250kHz / SF7 / EC4:6, explicit header), transmitting SSDV with the callsign ‘UBSEDL’. If you are listening to the RTTY, remember to turn off the ‘RxID’ button on the top right of dl-fldigi. There is also Contestia 16/1000 with RSID on this frequency. – 434.610 MHz USB: 300 baud RTTY, 850Hz shift, 8N2 transmitting telemetry and SSDV. This is powered from solar panels only, and hence is only expected to operate continously after about 0830 BST (before this it may transmit without a GPS lock, as the Raspberry Pi and GPS are powered down). Next is UBSEDS20, which is the experimental Raspberry Pi Zero board. The battery is expected to last a few days. It transmits Contestia 16/1000 with pips and RSID on 434.615 MHz USB, once per minute below 8km altitude and every two minutes otherwise. This is our first launch of this setup, so it seems unlikely that everything will go to plan!įirst is the UBSEDS19 backup tracker, which is powered from a single AAA Lithium Energiser battery. The combined payload mass will be about 70 grams, and the attempted float altitude will be about 13 km.

There’s more information about the tracker itself here: This launch is using a 1.9m envelope and longer payload train, and so we have a NOTAM in place.

We’re planning the first launch of ‘pico-pi’, our Raspberry Pi Zero based tracker, from Bristol this Bank Holiday Monday, August 29 between 05 BST. Online real-time tracking of UBSEDS balloons !mt=roadmap&mz=8&qm=3_days&q=UBSED*&f=UBSEDS20 There will be Slow Scan Digital Video (SSDV) transmissions. Richard Meadows M0SBU reports two high altitude balloons carrying 434 MHz payloads will launch from Bristol on Monday, August 29.
