Deer Mr. Lyls:
        As requested, we are providing the respanses to the supplementalquestions fr e
equipment autorization applcation for VHF—2100E (FCC ID: AJKB222168). This infomation is
provided in e atteched documents. Attechment one contains the responsesto the
supplemental questions and the secand attechment is the FAA coorcination later. If you have
any further questions, please feelfree to contact me

Responses to Supplemental Questions from Office of Engineering Technology oursuant to
Aplication for FCC Certiiation, RGC ID: AJKB227168 (Correspondence Reference
Number: 30553

1.) This device does not meet the definition of a Software Defined Radio pursuant to
Section 2.1(c)Please confirm that this radio was not filed underthe Software Defined
Radio Rules. SDR only permits one class II permissive change. More than one class II
permissive change requires a new applieation and a newFCC ID. For SDR you will
address security issues.
The device is not a Software Defined Radio. As a result, the application should not be
filed under the Software Defined Radio rules.

2.) The A3E, A3D and D7D modulation on form 731 does not lis the bandwidth for the
emission designator. What is the necessary bandwidth forthe three emission designstors?

The necessary bandwidth for the three emission designators are: A3E (SKOA3E), A3D
(IOKOA3D), and D7D (I4KOD7D). Also, could you make the following changes to the
Equipment Specifications section?

3.) Please explain the difference in output power for the occupied bandwidth
measurements on pages 19, 20, and 22 oftest report.
The output power (carrier power) varies because the different modes have independent
levels of adjustments.
