Liepa Research Scientist University of Michigan August 3, 2001 Re: Certification for Davis Derby EV16 Transceiver Model: EV16 FCC ID: O7WEV16US CANADA: to be provided by IC STATEMENT OF MODIFICATIONS As submitted for testing, the emissions were about 2 dB over the limit at the fundamental. This was traced to radiation of ground currents from the antenna outer shield. These currents were suppressed by placing a ferrite bead on the antenna cable connector at the PCB. Bead used: Fair-Rite #5961000201 (or equivalent). (Also see Section 3.1 of the attached Test Report). _____________________ Valdis V.
