Signal quality degraded over the pandemic.

Sutro Tower engineering done for time being.

I maybe now experiencing cellular interference.
T-Mobile LTE service officially available in my area.
T-Mobile tower between me and Sutro antennas.

SiliconDust support confirmed my tuner showed " very big spike of cellular phone activity at about 623MHz".

Big hourly and daily changes in signal quality.

(see tvfool.txt)


So could be something external to my antennas/amp/tuner.

I plan to order LTE filter which will block above 608 MHz.
Place filter after antennas and before RCA mast amp.
Will report back after experiment.
