Jim, I don't understand your terminology. In most common usage, positive and negative have nothing that relates to continuity - a continuity measurement is usually expressed as an amount of resistance (usually low) between two points. Alternately, the conductivity can be expressed in mhos, the inverse of resistance, but that is not normally used except in engineering.
As for making relay measurements in the Low Pass Filter area, every point will have a very low DC resistance to ground because T4 lead 3 is permanently connected to the LPF and the other lead of that winding (lead 4) is connected to ground. One must lift either lead 3 or 4 of T4 in order to make meaningful resistance or continuity measurements in the LPF. 73, Don W3FPR Jim Giercyk wrote: > All, > > I seem to have lost receive on 40m on my K2 (rev A, no 60m), and I am > thinking that I have a bad relay in the LPF stage.
