This frequency range is regarded as usual and customary by Public Safety Users including Police, Fire, Emergency Services, and their various departments. The BKR9000 Portable 2-Way Multiband Land Mobile two-way radio was designed to operate on frequencies that are in the frequency bands as shown in Table 1. To aid equipment authorization in other countries that accept the United States FCC Grant for Certification, BK Technologies, Inc. is requesting that the FCC list the frequencies 136-869 MHz for Rule Part 90 on the Grant. Also, for the FCC’s Rule Parts 90 applications, this radio is used in systems by Federal and Public Safety agencies including Police, Fire, and Emergency Medical Services, etc. as indicated in the table on the next page. Equipment programming is the responsibility of Authorized Service Personnel. It is important to note that the radio complies with 47 CFR Part 90.203(e); in which, the operator cannot directly program the transmit frequencies using the normally accessible external controls. Per “FCC-OET KDB Publication 634817” guidance, the grantee, BK Technologies, Inc., acknowledges that device operations on unauthorized frequencies are a violation of FCC Rules. Notes Emission Designators: Rule Part 90: 11K0F3E, 16K0F3E, 8K10F1E, 8K10F1D, 8K10F1W. BK Technologies, Inc. 7100 Technology Dr. W.

Introduction This Calibration Report has been produced in line with the SSI Dipole Calibration Procedure SSI-TP-018-ALSAS. The results contained within this report are for Dipole 1068. The calibration routine consisted of a three-step process. Step 1 was a mechanical verification of the dipole to ensure that it meets the mechanical specifications. Step 2 was an Electrical Calibration for the Validation Dipole, where the SWR, Impedance, and the Return loss were assessed. Step 3 involved a System Validation using the ALSAS-10U, along with APREL E- 020 30 MHz to 6 GHz E-Field Probe Serial Number 225.
