Re: [amsat-bb] subaudible tones on FT-847 in satellite mode

[Jeff Griffin <kb2m@xxxxxxxxxxx>]

 Hmmmm. I just put my 847 in sat (full duplex) mode, with the input of a
local repeater in VFO B with the proper tone encoded to bring up the
repeater. Then listening to the output of the repeater on another rig, Guess
what, it worked. So you can set a PL on the uplink! I must of screwed up the
PL, Wayne didn't mention the PL tone magically changes sometimes  after you
program  a repeater in Memory. But I don't use my 847 for repeaters anyway
so that doesn't present a problem here. I will try some more SaudiSat test's
tomorrow.
