Thanks for the information Terry. I searched the Phorum one more time and found someone else had the same problem with the RF choke opening up. Their solution to the problem was melting the wax off of the choke and repairing the break in the wiring. I tried the same thing and was also lucky in that the break in the choke wire was located where it could be repaired. After making the repair and recoating the choke with wax I reinstalled the choke and now the radio is playing perfectly on the FM band. Thanks again for responding.
