Actually, BLT 3 as above means send it every hour starting 20 mins
after the hour, and BLT 4 means every hour starting at 50 mins after the
hour. Between the BLT 1 /2 / 3 / 4, it will be sending its own beacon
out every 10 minutes, but they will go out direct 30 and 40 mins after
the hour, with a one hop path 20 mins after the hour, and with a two hop
path once an hour at 50 mins after the hour. See for an example of the

I didn't spot it before, but Andy AB9FX hit the nail on the head...
there is a digit missing from your longitude. The beacon text should

;145.11-AR*111111z3413.15N/09305.26WrT088 R25m Meet1StThur at EOC

It may or may not show up on the APRS-IS depending on whether it hits an
IGate direct or not. The important thing is that the beacon text for the
repeater object goes out every 10 mins direct with no path. Get some
sleep, and merry Christmas to you!
