Hi Koss and Paul,
I do not think that the "normal" center frequency is 436.795 MHz.
I use two frequencies for the downlink in SatPC32:
436.791 and 436.788 MHz.
I have heard it suddenly jump about 5 kHz during a pass - but that is some time ago.
The two frequencies above are not always spot on but close enough.
Have a nice weekend all.
