RE: [amsat-bb] ISS: How does the D700 switch uplink freqs ?

["RANSOM, KENNETH G. (JSC-OC) (BAR)" <kenneth.g.ransom1@xxxxxxxxxxxx>]

 The crew switches it manually. No automatic system is used for knowing
which region the ISS is currently over.

Most likely Bob has the answer to my qustion, but since I 
thought more of us would be interested I post it here:

Onboard the ISS the Kenwood D700 is used.
Region 1 uplink is 145.200
Region 2&3 uplink is 144.490

Assuming the D700 switches automatically, how is
that done, using GPS information that triggers the
correct channel to be used ?
