Weak downlink packet signal !!

A fluctuation on downlink packet signal strength noticed at
Ho-68 on Orbit #706 time 19.42 UTC, Max El 47 .
Firing up my Preamp and changing the antennas polarization didn't help!
The average efficiency was 20 % for that good pass!!
For sure there were several factors for this weakness!!
I I've noticed this twice.
