Hi Chris and Roy,
... we can't see a difference in the received signal strength on the ground, but any independent validation of that is greatfully received.
Subjective observation is that my received signal seemed weaker for the past 2 or so days. The antenna I'm using is a 7 element yagi on 435.800 at 20 degrees fixed elevation on a TV rotor. I've only been able to capture fewer than 50% of the packets compared with reception earlier in the week.
I live on a 100% wooded lot (no leaves since its winter) but all the trees are frosted ala winter wonderland style from passing weather systems since last Thursday. The trees introduce a lot of variability in my received signal depending on which tree I'm pointed at. But my received signal on 435.800 has been noticeably lower even at the "good" patches of sky.
My HuskySat telemetry at 2125Z said Forward Power = 13.4 mW.
