| Notes: | 1) Power measurements taken at 4.5 watts to allow 3/4 scale deflection of analog Telewave meter. | ||||||||
| 2) Current measurements rounded to 5 mA and averaged where multiple measurements available. | |||||||||
| 3) Receive current during TX measurements was 120 mA by K2 display, 127 mA by Fluke 87. | |||||||||
