This is the same technique we have used (except without the HTs) when we are setting up a dish on a tripod, but I was really hoping that there was a better way. And it is quite possible that the tower climber will have experience with this. At this point, we don't know who the tower climber will be, since KOIN requires that we use climbers approved by them.<div><br></div><div>I agree that scan sucks. Also, for aiming, an analog display really would work better than a digital display. That is why I was hoping that I could get Aim Master to work. (If anyone can tell me what some suitable SNMP OIDs for aiming an antenna, I will try to update Aim Master. Perhaps this would be a better solution.)</div><div><br></div><div>Herb<br><div><br><blockquote type="cite"><div>On Jan 29, 2020, at 4:32 PM, Kenny Richards <<a href="mailto:richark@gmail.com" target="_blank">richark@gmail.com</a>> wrote:</div><br><div><div dir="ltr"><div class="gmail_default" style="font-family:arial,helvetica,sans-serif;font-size:small">Herb,</div><div class="gmail_default" style="font-family:arial,helvetica,sans-serif;font-size:small"><br></div><div class="gmail_default" style="font-family:arial,helvetica,sans-serif;font-size:small">The approach which has always been used when I have been involved uses the output of /interface wireless scan 0, but it really requires two people. </div><div class="gmail_default" style="font-family:arial,helvetica,sans-serif;font-size:small"><br></div><div class="gmail_default" style="font-family:arial,helvetica,sans-serif;font-size:small">1) person on tower preps the dish and does their best to aim it in the right direction.
