(c)(13) Description of all circuitry and devices provided for determining and stabilizing frequency. Description of any circuits or devices employed for suppression of spurious radiation, for limit- ing modulation, and for limiting power. This circuitry is described on page 10. Limiting Modulation: The transmitter audio circuitry is contained in IC101, IC102 and IC103. Limiting Power: There is no provision for limiting power. (13) Digital modulation. This unit does not use digital modulation. 2.1033(c)(14) The data required by 2.1046 through 2.1057 is sub- mitted below. 2.1046 RF power output. RF power is measured by the substitution ERP METHOD. With a nominal battery voltage of 9.0V, and the transmitter properly adjusted the RF output measures: MAXIMUM OUTPUT POWER: .030 WATTS ERP R.F.

From 100 to 250% of the authorized band- width they are attenuated by at least 35dB and beyond 250% 43 log(Po) dB. The plot shows the transmitter modulated with 15000 Hz(the highest modulation frequen- cy), adjusted for 50% modulation plus 16 dB. The spectrum analyzer was set with the un-modulated carrier at the top of the screen. The test procedure diagram and occupied bandwidth plots follow.
