[amsat-bb] SatPC32 Doppler Correction/Calibration?

[David Rush]

I'm trying to get the doppler correction/calibration set up for the 
various birds before Field Day, but I'm just not making any tangible 
progress.

I've got a pair of Yaesu FT-817ND rigs, and can successfully tune both 
of them with SatPC32's CAT controls.

Following the directions for a two-rig calibration process, I've been 
catching the XW-2* birds and can occasionally get the downlink 
correction set to where I can hear myself on the downlink.

In a couple of cases I've made note of where that downlink calibration 
was near mid-pass (the necessary correction changed constantly across 
the pass).

Then I go into the CAT menu, set the downlink correction to zero and the 
uplink calibration to the opposite sign of the previously found downlink 
correction at mid-pass.

For example on a recent pass of XW-2C I found a downlink correction of 
-160 Hz was working well near mid-pass (I could hear myself) so I set 
the uplink calibration to 160 Hz.

The "Upl. Calibr." window in the CAT pop-up says "160", and the grey box 
above the uplink frequency in the main window also says "160".

I click on the "Change/Store Dataf File" button, then click on the 
"Store" "Uplink Calibration" button on the next pop-up.

It says "The changings have been stored!" but the uplink calibration in 
both the first popup and the main window are back to zero.

I click the X to close both pop-ups, and uplink correction in the main 
window is still 0.  I exit the program, restart it, select XW-2C, enable 
CAT (C+) and the uplink calibration is still on zero.

What am I missing?
