Hi Moneo,
Took so data from our old friend FO-29 this afternoon. 17:10 Saturday.
The satellite was over Greenland and in sunlight.
I was surprised to see such a low power for the TX. 376mW rising to
only 499.9mW in the other data frames.I don't think I have ever seen
it so low. The beacon was easily copied almost down the horizon.
If you have a few minutes I would be interested in your comments.
