K3 with MFJ Bias Tee

Franki ON5ZO
Hello folks

I want to switch an A/B relay remotely by applying 12V through the coax. I
have a pair of MFJ bias tees for that, never used before.

When I apply the 12V and measure with my DVM on the 'RF only' coax terminal,
there is some diminishing DC voltage for a brief period, say about 2 seconds
(DVM not really fast). I assume this is the DC blocking (series) capacitor
loading or discharging (when removing the 12V).

Should I worry about this? Can this hurt the K3 in any way? Or can I just go
along? Better safe than sorry...
