After years of installing FSK radios, we never had one fail that wasn't due to some kind of external factors (tree falls on SM, bolt slips and SM flips upside-down and fills with water, Power company voltage doubles (with old-style transformer PS), etc.

The very first PMP450 SM we installed had a weird problem where it would link up, test near 100%, but when it came to passing actual customer traffic, it would fall flat on its face. I was convinced that I had some router or other problem, tried about a dozen things before I just swapped the SM. Problem solved, but it did not give me a warm and fuzzy feeling about the new platform. Haven't had one fail since though...

It would be interesting to know what if any radios go through any functional testing before they ship. Years ago, all electronic devices went through 100% testing, I’m guessing today very few are even powered up at the end of the production line. I know I’ve seen a few routerboards with 1 bad Ethernet port out of the box, and radios that power up with some kind of warning notice like not calibrated. I do remember a plant tour video from the Orthogon guys on the testing, burn-in and calibration they do (or at least did at the time) on every PTP radio. Maybe licensed radios all get tested before shipment, I don’t know. Maybe airFibers.

I had a bad SM already. We believe a defective AP as well. I have 8 installed.

        Couldn't get it to stay connected long enough to run one tried
        running a speed test a couple of times and it would vary
        anywhere from two mag to 30 meg before it would drop

Ok so I go to the tower today replace the Epmp AP with a Rocket M2 on the same antenna (Dual slant) and test with
            a Nano M2 at the same place I tested yesterday.  I get
            -44 signal 95% Quality and 96% capacity and speedtests as
pictured. What is the problem with the EPMP equipment. So far I am not impressed. IF the EPMP thinks the noise
            floor is -60 ish and a UBNT has no problem getting great
            thoughput I guess we will stick with the UBNT

            Ok  so as an experiment I moved my 2.4 FSK omni to the
            same channel that this EPMP sector was on at the same
            height on the same tower.  All 41 customers reconnected
            to the fsk omni and all link tests are in the upper 95%
            and better on all customers
            So why would this spectrum be so dirty for the 90 degree
            EPMP sector but usable and great link tests for the FSK
            omni  at the same height.?

            Cant use 5Ghz  All my BH links are in 5ghz and I cant get
            though trees with 5ghz. 90% of my customer base is behind
trees. This is not the tower I plan on leaving it on. But I dont understand why the noise floor would be that
            high here.  It is 3 miles from any town and sits in the

                        Have Java installed, run that program.
                        Connect to that radio.

                        So I switch the AP to Spectrum analyzer mode

                        Monitor wireless might have a scan what
                        you're after.  I think that's only compatible
                        (ie TDD OR wifi not both) networks seen.

                        Uplink issue, noise and all that basic rf stuff?
