With a GPS, a small display could provide all the details of nearby repeaters and for radios with computer controlled programming, the radio could be tuned to frequency and other operating parameters by touch selection. </div><div><br></div><div>The RTL-SDR could also look for active repeaters (and simplex) nearby and provide similar programming.</div><div><br></div><div><br></div><div><br><div class="gmail_extra"><div class="gmail_quote">On Wed, Nov 29, 2017 at 8:09 AM, Robert Bruninga <span dir="ltr"><<a href="mailto:bruninga@usna.edu" target="_blank">bruninga@usna.edu</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div lang="EN-US"><div class="gmail-m_70346193248509615WordSection1"><p class="MsoNormal"><span style="font-size:11pt;font-family:Calibri,sans-serif;color:rgb(31,73,125)">APRSSIG thoughts about Mobile TRAVEL operations.</span></p><p class="MsoNormal"><span style="font-size:11pt;font-family:Calibri,sans-serif;color:rgb(31,73,125)"> </span></p><p class="MsoNormal"><br></p></div></div></blockquote></div><div class="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div dir="ltr"><div dir="ltr"><br><hr><div style="float:left;padding-left:1em"><font><font><font color="#0000ff">John D.
