[amsat-bb] SO-50 jumped 5 kHz up in downlink frequency

Hi all, I listened yesterday to SO-50 and it appeared to be 5 kHz higher in frequency than normal on the downlink - approximately. Tested it right now and got it confirmed. Did anybody else hear it ? The pass had AOS at 1840 UTC here in Copenhagen.

I have heard this before - but it is a long time ago. 73 OZ1MY Ib
