does anyone here have any suggestions?

Bring it down? You mean bring it up. It's resonant about 6 mhz or so.
To tune it for 30 mhz, you would need to cut about 28 ft or so off of
it. If you are severely overloading, cutting off a few ft would be a
good place to start anyway.. You probably can't handle more than 5-10
ft by the sound of it... MK

Here's an idea: Instead of alligator clipping the wire to the antenna,
loosely wrap about 6 - 8 turns of the wire around the whip so it
inductively couples to the antenna. If the radio is indeed
overloading this could solve the problem; not as much signal is
transferred to the whip as with a direct connection. I've done this
with portables and have had success, your mileage may vary.
