September 29, 2000 Federal Communications Commission Equipment Approval Services 7435 Oakland Mills Road Columbia, MD 21046 Attn: Ms. Katie Hawkins SUBJECT: Wittsburg Enterprises Ltd. FCC ID: O5I-200 731 Confirmation No.: EA98488 Correspondence Reference No.: 16377 Request for Tech. Info.: 9/28/00 Dear Katie: Transmitted herewith, on behalf of Wittsburg Enterprises Ltd. is an amendment provided in response to the request for technical information dated September 28, 2000. 1. We confirmed that the WD-2000T contains a switch SW 1 on the schematic diagram that automatically deactivates the final amplifier (by removing all of its bias voltages) so no output is generated by the transmitter 3 milliseconds after the switch is released. We trust this information is sufficient to issue the grant ASAP. If you have any further questions, please do not hesitate to contact us. cc: Wittsburg Enterprises Ltd.
