JOE DICHOSO FCC SUBJECT: FCCID: K66HX292UT REFERENCE: EA94052 1. Attached you will find new schematics and block diagrams that have been enlarged to make them more readable. 2. Also I have enclosed new necessary bandwidth calculations based on the modulation plots for both the 25KHz channel spacing & the 12.5KHz channel spacing sent with the 22 July 1999 informa- tion. 3. The necessary bandwidth have been corrected so that the emis- sion designator can be 16K0F3E & 11K0F3E accordingly. 4. Additionally I have been instructed to add FCC rules Parts 22,74,90, & 90.210 to the 731 form. 5. I have also enclosed a letter from the applicant that should cover the 90.203(g) requirements. If you have any questions or require any further information, please advise. Regards, Sid Sanders SAH/hs F:\CUS\Y\YAE\YAE145\YAE145X9.RPT TABLE OF CONTENTS LIST APPLICANT: YAESU MUSEN CO., LTD.
