PS-25 and PS-26 PICO balloons were released on Sat 22 Nov 2014, testing out multiple balloon tracking with JT9 and WSPR.
Solar powered 10mW TX HF payloads transmitting JT9 and WSPR with frequency offset of 400Hz for JT9 and 100Hz for WSPR, they could be tracked simultaneously with the modified WSJTX software.
Tracked on SNUS as PS-25 and PS-26.
Callsign on JT9 is VK3YT, and callsigns on WSPR are VK3YT and VK3ANH
TX time and frequency schedule:
0 30m // Mandatory JT9 and WSPR, two per hour
6 30m // Optional JT9 – bat full
10 20m // Optional JT9 and WSPR – batt low
16 20m // Optional JT9 – bat full
20 30m // Optional JT9 and WSPR – batt low
26 30m // Optional JT9 – bat full
30 20m // Mandatory JT9 and WSPR, two per hour
36 20m // Optional JT9 – bat full
40 30m // optional JT9 and WSPR – batt low
46 30m // Optional JT9 – bat full
50 20m // Optional JT9 and WSPR – batt low
Update #1 6:30pm
Multi tracking was working well, but PS-26 landed in the Tasman sea shortly after leaving the coastline.
PS-25 is still heading East towards NZ. SNUS callsign is PS-25, and WSPR callsign is VK3ANH.
