Hi Ian,

WIDE2-1 is a globally acceptable path for balloons, recommended by Bob Bruninga WB4APR, the founder of APRS.

Int the early days of APRS pico balloon flights over the eastern states, some effort was made to check for impact to the network from a high altitude balloon using WIDE2-1, and no issues were observed with a 5 minute TX interval.

PS-61 transmits one compressed APRS packet every 5 minutes in full sun, and every 10 minute at night.

Regards,
Andy VK3YT
