Have a SB 104A was working fine. Moved the unit across town and now when I turn it on it is stuck on a frequency. On the 40 meter setting it is on 6.603, on 20 meters it is 16.603, on 15 meters it is on 16.603 and on 10 meters it is on 16.603 Note the freq will not change when I turn the dial. Any input appreciated. Kevin k8su at adelphia.net
