This is really beginning to irritate me, Now the guy who replaced the gear is still blaming us for the problems here, I moved the ubnt gear clear down to like 5.1 or whatever the lowest channel is, the spectrum at this and the remote site are deplorable. The Signal/Noise ratio is moving around on the ptp650 and the Vector Errors are off the chart, but he still wants to blame our equipment.
I can tell you it boils down to an improper system repair post disaster. I pulled screen shots, both before and after I moved our channels, showed them the issue with their own colocated radios, turned on assymetric channels, yes, they were running symmetric in a high noise environment, nothing could go wrong there, right? Now tomorrow, my boss is going there to unplug our radio, taking our customers down. Im betting some utter nonsense like capacitant power or our antenna shape ends up being to blame here. I know ubnt is shit and bleeds noise allover, this particular radio is a rocket m5 with the 30db dish and the shield kit. The link is 90 degrees off both of theirs (ours is west, they have one north and one south) I believe we have 30 foot vertical sep between it and their closest radio. I can see how a rocket would magically destroy the whole 5ghz spectrum and not have performance issues itself.I even cycled the UBNT radios to make sure that they actually did change channels. ATPC power ranging not matching current TX output and RX doesnt make any sense to me. Interference alone will not alter RX power unless its very very notable. And then to top it off its said it would be better to move completely off the band to 3ghz since it cant interfere. Yeah, great fucking idea, lets take the only semi clean spectrum left and burn it on a backhaul thats performing as it should because other people dont know how to troubleshoot their own damn gear. But the kicker to that would be "oh, you must still be interfering, that m365 is actually a 5ghz radio downconverted how bout this, climb the damn tower and fix the fuckup fucking meh On Tue, Sep 23, 2014 at 5:04 PM, That One Guy via Af <af@afmug.com> wrote: > Im not doing anything, this is a not my chair not my problem issue. > > This strike blew everything on the tower, if it was electronic, it cooked, > the switch was sitting on back of the APC and welded to it even tripped the > breaker > > Im just curious with these if theres any issue with the ATPC on these bas > boys > > On Tue, Sep 23, 2014 at 4:42 PM, David via Af <af@afmug.com> wrote: > >> Inspect the cables or at lease switch one or both out at one end and see >> if a prevalent change is made. >> Could be a feed horn but unlikely I would shoot for pigtails first. >> >> >> On 09/23/2014 02:38 PM, That One Guy via Af wrote: >> >> I just got done troubleshooting a 650 link for our landlord we are coloed >> with on a couple towers.
