I must have a bad ground since I'm getting 0 activity on 6 and 10
If you mean a bad connection somewhere, I'd agree. Check all connections for proper continuity and no shorts. If you can substitute feedline with known good, that's another way to check.
Don't put a lot of time into the magic earth ground, though. No matter what some other guy tries to tell you, that is not it.
A quick and dirty way to test any receiver is to simply attach a random length of wire to the center pin of the antenna connect and see if you hear more rush noise, even may hear a station. If you do, suspect feedline and/or antenna. This kind of test antenna can be a few feet to 30 feet or more of any gauge wire, stretched out across the floor. If the rush immediately is a higher level than what you get with the antenna, that's a pretty good clue that there's something wrong in the antenna system.
AND -- DO NOT EVER ATTEMPT TO TRANSMIT INTO THAT RANDOM WIRE. If the radio is the type that can still receive with mic disconnected, good idea to disconnect the mic first and don't reconnect until you are on a proper antenna again!
