    I had a similar situation on a AL-811 and solved it with retuning the input coils.But you have to pay attention
    as you have to `devide ┬┤the tuning on the same coil between the two bands.In other words,max input on one
    band is not nessecarely max input on the other so you must devide carefully as well choose your most ususal
    operating frequencie.
