r Even if the Automatic Antenna Tuner successfully normalizes the impedance presented to the radio, feedline losses will escalate rapidly with increasing SWR at the higher operating frequencies, especially 28 MHz. r Although high SWR itself does not cause feedline radiation, the sudden onset of ...
In cooperation with the FCC,illegal radios and amplifiers will be deleted from the system. This includes all uncertified HF amplifiers manufactured for use on CB frequencies -- even if they are disguised as ham radio amplifiers. Please seehttp://swap.qth.com/fccfor important information regarding...
