Well quite right as Andrew and others pointed out ..
Its Mic-E .. I realised that after sending the mail and reading a few other
replies .. Flame on ..
Its just that Ive never seen it plot on a map in Ui-view and I dont go
looking at 0 0 very often .. Its all been explained .. I am used to seeing
Mic -E frames starting with S so it never clicked into place ..

The APRS Protocol Reference Document, chapter 10, page 42: Mic-E Data Format
explains that. For mic-e the destination field get a different use.
In the case of the ISS beacon, P0PPP0 is allowable and decodable.
As previously pointed out, UI-View has a lock out for any beacon that has
both 00 N/S and 00 E/W. Most other programs, and the Kenwood TH-D7 and
TM-D700 pair, will decode it. It is a D700 sending it down to us. If only
they would hook up a GPS to it!
