Hey Terry--hope you're okay first off. Speed wobbles are scary as heck. Second off, just as a courtesy to other readers, accidental caps lock (given the things you seem to want to capitalize are lower case) comes across as you using a megaphone directly into the side of someones ear. Not so pleasant. :)
(pretty sure tridork covered this but to reiterate)
First thing to check is that your front end is assembled and appropriately tight. Loosen that top-cap a smidge, loosen your stem/steer tube clamp bolts, snug up the top cap until it barely starts binding (steering gets a bit "tight") then back off an 1/8 of a turn or so, and tighten up your stem clamp bolts again.
Second, make sure your wheels are squarely mounted in the dropouts and the brakes are centered on the wheels. Yes, I've seen this happen, especially with zealous skewer clampers.
Third, wheels are true? Tires are installed nicely and in good shape? (deflate, walk around the rim pinching it inwards making sure that no tube accidentally snuck under the bead?)
Lastly, while riding, at good thing to do is unweight the saddle and pinch the top tube between your knees when going down hills (feet at 3 and 9 on the crank). This completely changes the resonance of the bike.
Hope these help!
The question of who is right and who is wrong has seemed to me always too small to be worth a moment's thought, while the question of what is right and what is wrong has seemed all-important.
