Re: problems with "The Station"



Hi Kevin -

To use The Station on fm birds what I do is first setup a narrow frequency
range around the birds uplink and down link.  For example on uo-14 I put in
an uplink of 145.965 to 145.985 and downlink of 435.090 to 145.050.  This is
in the full duplex setup screen.  Then when I open the full-duplex window, I
click TX fix and "tune" the RX TRANSPONDER frequency to the transponder
downlink - nominally 435.070 which works fine although I think I've seen
some more accurate numbers on the reflector (I think its WB6QIS).  It is
kind of hitting a moving target cuz the transponder frequency moves in this
mode - but when I get close I click on FDT and it locks in.  Then I'm all
set.  It works just fine - you see the rig frequencies both changing for
doppler, but the transponder frequencies stay stable.  I don't have to touch
a knob.  Unfortunately, you have to redo this every time you close the
window or "The Station" because it doesn't retain the FDT settings.

I assume you are right on the delay in ms.

Hope this helps.
