Quick follow up. Climb resolved it. Hung a P10 and we saw a 7db change on those customers having issues. They dropped into 2x and are running well. I did not compare the numbers on the closer customers.

Ok so to answer Steve's question. No filter on this I have never seen one of the filters but have heard of them. I should point out that this AP is deployed now. The test as a SM was done a few weeks ago along with a bunch of other equipment most SMs came in around -72 a few came in around -80. We tested a couple APs and they both were -80ish. We assumed at the time that it was normal. Now I am doubting that assumption. This deployed AP is having some issues with far out SMs in the 8 and 9 mile range. The AP it replaced was not having these issues although this one is higher in elevation than the last one so not everything is identical. At this point a climb is planned for the AM to put in a p10 AP.

So 2 different Canopy units can in the exact same situation and signal can show a difference up to about 10db. The calibration setting affects what signal level the SM shows but don't play with that as you can fry the radio as Paul found out. _____ From: "Brandon Yuchasz" <li...@gogebicrange.net> Sender: "Af" <af-boun...@afmug.com> Date: Tue, 30 Jun 2015 17:04:43 +0000 To: <af@afmug.com> ReplyTo: af@afmug.com Subject: [AFMUG] FSK 900mhz AP to SM should it read the same as a SM? So I am trying to trouble shoot some APs. FSK 900mhz. I have a P9 AP when I set it to run as an SM it reads a -80 but when I put an actual SM in its place it reads -72. Should there be a difference between these two units or do I just have a crap AP? Best regards, Brandon Yuchasz GogebicRange.net www.gogebicrange.net <http://www.gogebicrange.net/>
