RF on the power supply line? I would wrap a couple of turns of the power lead through a 31 mix ferrite.

I have an ATU-100 in auto mode, remotely mounted with a 4:1 balun for a Doublet.
With 10 watts continuous carrier into the ATU it finds a 1.1:1 match and then about 5 seconds later retunes to the 1.1:1 match, it cycles this continuously while there is rf present.
Any ideas why.

I want to setup my ATU-100 in a waterproof box at the base of my 111ft (34mtrs) Inverted "L" Long Wire.
I gather that if I momentarily ground RB1 just once to will push it into Automatic mode and save to memory.?
Question . . . Is RB1 the pad on the underside of the PCB, marked B1 alongside B2, A7 and A6 ?
Hopefully, that simple.
Many thanks
