T-2350 Emission Designators Analog Transmission Emission Designator – Transmission Characteristics Per FCC rule Chapter 47 Subpart C Part 2.201 Section (c) (3) - F Section (d) (4) - 3 Section (e) (6) - E Emission Designator – Necessary Bandwidth Relevant FCC rules: Chapter 47 Subpart C Part 2.202 section (c) (1) Section (g) Table III-A 3: Bn = 2 (M+DK) Section (e) Bn - the necessary bandwidth M - the maximum modulating frequency in Hertz D - the peak deviation in Hertz K - the specified constant for FM sound broadcasting, in this case K =1 For the T-2350 Narrow Band Mode – M = 3000 D = 2500 Therefore Bn = 2(3000 + (2500*1)) = 11KHz The Emissions Designator for the T-2350 Narrow Band Analog mode is 11K0F3E For the T-2350 Wide Band Mode – M = 3000 D = 5000 Therefore Bn = 2(3000 + (2500*1)) = 16KHz The Emissions Designator for the T-2350 Wide Band Analog mode is 16K0F3E

Digital Transmission Emission Designator – Transmission Characteristics Per FCC rule Chapter 47 Subpart C Part 2.201 Section (c) (3) - F Section (d) (2) - 1 Section (e) (6) - E Emission Designator – Necessary Bandwidth Relevant FCC rules: Chapter 47 Subpart C Part 2.202 section (c) (4) Measurements per Rule Part 2.202 Section C (4) were done because Part 2.202 Section g Table III A 1 formulation produces an excessive result using the value of K recommended in the Table. Therefore the 99% energy rule (title 47CFR 2.989) was used for digital mode. A representative T-2350 was tested using the same setup as in the Occupied Bandwidth findings of this submission. The results are presented in the following figure: Therefore, the Emissions Designator for T-2350 Digital mode shall be 10K0F1E
