Hi all,

On the one good pass over ZL so far I had to use a +6kHz offset on my uplink
to receive on the nominal downlink frequency.
i.e. satellite input frequency of 535.556 (nominal 435.550) to hit the
145.900 satellite output frequency.

Hi all,
The transponder was working at the pass with AOS at 
0926 UTC here in Copenhagen.
Had a couple of QSOs with HA2RD and PE1ITR.

As far as I can make out the frequencies are different 
from the published ones.

Just after the transponder was turned on I har to go 
to an uplink of 435.565 MHz to get 145.900 MHz down.
This is the nominal pair I used in SatPC32.

After some time had to adjust the uplink down to 
435.563 MHz.

Can someone confirm this ?
