Probably a different length ground lead would help. Other better options
are to series resonate the gnd lead on 15m or attach one or more 1/4
wave radial wires to your rig. MFJ sells a device to series tune your
gnd. I believe it is a series resonant tunable LC and a sensitive
current meter to tell when max gnd lead I is found. 73, Dan, N5AR
