should be 0 ohms.</div></div><div><div class="yiv486387508MsoNormal"> </div></div><div><div class="yiv486387508MsoNormal">2) Have ypu checked both the center conductor and shield of the antenna cable for 0 ohms resistance, and infinite resistance between the center conductor and shield?</div></div><div><div class="yiv486387508MsoNormal"> </div></div><div><div class="yiv486387508MsoNormal">3) Have you checked the antenna to make sure it is resonant at or near the frequency you are transmitting at using an antenna analyzer?</div></div><div><div class="yiv486387508MsoNormal"> </div></div><div><div class="yiv486387508MsoNormal">4) Have you verified the radio's output power using an external power meter?</div></div><div><div class="yiv486387508MsoNormal"> </div></div><div><div class="yiv486387508MsoNormal">Other, more obscure things to check are mic gain and transmit modulation percentage.</div></div><div><div
