PS-23 is planned for release on 18\/10\/2014<\/p>\n

Solar powered 25mW TX
\nHF payload will transmit on 30m and 20m using Olivia, JT65 and WSPR.=<\/p>\n

WSJTX software has been modified to assist with automatic software tracking and uploading to spacenear.us<\/p>\n

Windows install file:
\nwsjtx-1.5.0-devel-win32.exe<\/a>
\nSource files:
\nwsjtx_src_1.5_devel.zip<\/a><\/p>\n

\"PastedGraphic<\/p>\n

The new “Telemetry” Option in WSJTX will enable uploading of received JT65 packets to a server on the internet where the packets are correlated, processed and uploaded to spacenear.us
\nThis is the only change in the software, ie. with the option turned off it behaves like a normal WSJTX application.<\/p>\n

– WSPR on 30m (dial 10.138700Mhz) and 20m (dial 14.095600Mhz)
\n– Olivia on 14.075000Mhz centre (dial 14.074000Mhz)
\n– JT65 on 10.142000Mhz and 14.075000Mhz centre (dial 10.141000Mhz and 14.074000Mhz);<\/p>\n

Update #1 10:50pm 18\/10<\/p>\n

The balloon was tracked all the way until it landed near Tamworth, by VK1, VK2, VK3, VK5, VK6, VK7, ZL1 stations, using Olivia and JT65 on 30m and 20m.<\/p>\n

We had WSPR spots for the balloon from as far as the US, 15,000km away.<\/p>\n

Payload #2 of PS-23 will be released tomorrow.
\nInitially planned for a multi balloon tracking test, it will do WSPR, Olivia and JT9.<\/p>\n
