K3 T/R relay making poor contact on receive


Started about a month ago and I thought it was a loose connection, but SWR was fine but both the RF S meter and the P3 display would be down several S units. Keyying the PTT a couple of times clears the fault. Went though the manual and could not spot the relay but figured it was on the KANT3 PCB.  If so what is the best way to trouble shoot the problem or just replace the relay??
