Chk. for a poor connection wear entenna plugs into radio, it could have corrosion or it could just be loose.

How do I "test the antenna ground"?
Thanks, just tried that and the ohm meter stayed at didn't change at all. It started at 1 and didn't move.
Sorry, my mistake. Thought I would try this again and use a better ground source, this time I got about an 8 on the ohm meter. What now?
Pull the anteena lead out of the back of the radio, use a ohm meter and touch the sheet metal of the car u should not have more than 3 ohm's on the outside of the metal antenna plug that goes into the radio.
test the antenna ground.
clean the mounting of the antenna and retest, if it improves try the radio, do u have poor reception on both AM and FM? if so the radio is most likely the problem but a better antenna ground is essential for quality reception, u are testing the part of the connector that surrounds the inner plug? often the problem can be the connector end is not making good connection to the coax cable ground, new plugs can be had at Radio Shack.
