<div class="yiv3200863572MsoNormal"><span style="">I decided to do my own research beyond the reference sent. The first article below from Mar 28<sup>th</sup> seems to be all sunshine and lollypops about Ligado not interfering with GPS receivers.
Evidently the other articles all cast doubt on the state of testing for interference. I have read enough to be convinced to support the proposed statement to the FCC.</span></div>
