I just added IO-86 to my APRS Satellite page: http://aprs.org/sats.html Its telemetry is in standard APRS format and users should also show up on the user link page on FINDU. With a 5W output this should be the strongest APRS satellite on 145.825 MHz. Did I get all the links right?
But you have to be below 30 deg latitude to ever be in the footprint. But if you were on the equatior you would get 14 passes a day every 110 minutes all day long!!
Are there any other APRS digipeating satellites that I have overlooked?
It looks like a standard APRS digipeater, but I don’t see the usual generic ARISS or APRSAT digipeat aliases... So I guess this means you have to user the YB0X-1 callsign to digipeat?

Since I also added a telemetry counter, it looks like (IO-86) Resets the telemetry counter about every 20 minuites or so and then has big gaps up to 12 hours or so. Since an equatorial orbit should have maybe a 65 minutes in the sun and 35 minutes in eclipse, does this mean it takes almost 40 minutes in the sun on each orbit to have enough power to transmit, and then only lasts until the next eclipse?
Or is there a better explasnation?

Bob,
Possibly because IO-86 operates on a schedule and the digipeater is only on for certain periods.
The team just posted the latest weekly schedule at https://twitter.com/lapansat/status/1170807973272158208?s=21

APRS on IO-86 has aliases of ARISS and YBSAT
The APRS is active on a schedule alternating with the FM repeater and the other primary payload of LAPAN A2/ORARI. Typically one in the morning and another one in the evening.
Please check twitter @lapansat for the weekly schedule.
Next weekend will be the 4th anniversary of IO-86 satellite . Currently we have not observe any reduction of performance of this relatively “high power” (5 watt on both FM Repeater or APRS).
