INTRODUCTION The following data has been taken in support of an Application for Type Certificate for the Eagle Wireless International Extend-A-Page VHF Exciter (FCC ID: LOK150-TX-UHS- 2) in accordance with Part 90 of the Federal Communications Rules and Regulations. The equipment under test (EUT) is a VHF Exciter which operates between 150 - 174 MHz. This particular unit performs digital and analog modulation, and is tested as such. Bands 150 – 174 MHz are covered under Part 90.205 abd evaluation of the ERP must be done at the time of installation with a power amplifier. This unit is not to be used without that power amplifier. 1.1 Test Facility: Noted and Complies. This test site is located adjacent to the building in League City, Texas, 77573. All equipment is calibrated and traceable to NIST. Calibration period is 1 year. Wayne Langston, Inc. has received NVLAP Accreditation, Certificate No. 200021-0. 1.2 Test Samples: A representative sample of the Equipment Under Test (EUT), was tested and the test results for this sample provided are located in Appendix. 1.3 Test Results: The results from this testing apply only to the sample that was tested. The findings do not make any suggestions about how the product is to be used nor does Wayne Langston, Incorporated make any recommendations regarding the product's usage. 2.

Data are presented in tabular and/or graphical form. Measurement procedures are described within the text of each reported test. All bandwidth measurements were made using ± 2.4 KHz deviation . 2.1046 Power Output The following power measurements were made at 150, and 174 MHZ. The test setup is as follows: EUT-----------Power Meter -------------50μ/500 watt load 50 dB pad ---------------8567 The amplifier’s RF output power was measured using a Boonton Model 42B Micro watt meter. External attenuation was added to prevent overloading the equipment. The input of the micro watt meter presented a resistive load of 50 ohms to the amplifier which precisely matched the exciters output characteristics. The meter measured an output power …
