In this case, the primary is in the tuned circuit. The secondary appears to be a step down, probably to match the lower impedance of the RF amp input. If I touch the primary of the antenna on the tuning cap, it is a little better. If I touch the secondary at the base terminal of the RF amp it is somewhat better. I've used my signal tracer with RF probe before on other front ends with no results. I think I will use my scope and generator and see what I come up with, probably after the holidays. I appreciate all your input, thanks
