Change frequency and see if CCQ improves, you have i assume no fresnel zone issues http://www.afar.net/fresnel-zone-calculator/Could this be interference? The beam passes over a harbour with ferries coming and going at intervals - tho' there would have been a 4.00 am one.
Ha! I presently have a collection of 7 (seven) Ubiquity SR5 cards that have failed on this link in the course of two years and am half expecting the current problem to be down to the pending failure of the eighth after an impressive three months service. Forgive me if I have some reservation in trying an XR5. That's one of the reasons I tried a R52Hn, tho' I won't be trying any more as even the small print neglected to point out that I needed a minimum of RouterOS v4.03 to run the thing. Many of my RBs aren't upgradeable to v4 and I'm damned if I'm going to fork out US$45 for another licence just for the privilege - Toyota marketing again.As your using Ver3.30 i would recommend 2 X Ubiquiti XR5 radio cards there are the business I have a link running at 96-100% CCQ,
XR5 cards are the most stable cards out there I think. 100% ccq on every single one of ours, same links with anything else and its horrible.Forgive me if I have some reservation in trying an XR5.
Routerboards always can be upgraded (so far). If it says you can't just go as high as it lets you, and then it will let you upgrade again to the next higher. Even the 1xx series boards can be upgraded to 5.x if I remember right.Many of my RBs aren't upgradeable to v4 and I'm damned if I'm going to fork out US$45 for another licence just for the privilege - Toyota marketing again.
Not my understanding, and not what the Wiki section on licensing implies, vis:Routerboards always can be upgraded (so far). If it says you can't just go as high as it lets you, and then it will let you upgrade again to the next higher. Even the 1xx series boards can be upgraded to 5.x if I remember right.
Damn well ought to be at the price - Mikrotik R52Hn=NZ$104. Ubiquity XR5=NZ$179.XR5 cards are the most stable cards out there I think.Forgive me if I have some reservation in trying an XR5.
I have never had a failure of a XR5 this probably due to I being extra cautious when installing them (yeah I agree they are costly) and as you have mentioned 7 SR5 failed on just one link?Ha!

For the most part the failures were sudden - the link just stopped working. Part of my problem is that one end of the link is at the end of a difficult forty-minute quad-bike wrestle up a mountain and the other end a two-and-a-half hour drive away, and I'm not aware of any easy way of telling which end has failed. So I replace the mountain-top end first and if the link stays down replace the other end and assume the moutaintop one was OK and can be re-installed at a later date.(1) I forgot to ask at first was this link working OK and just deteriorated over a period of time or just not good from the start?
Difficult to say, as I'm beginning to suspect the problem was interference all along.(2) Has the SR5 failure happened just at one or both locations of this link,
In the absence of obvious damage I tend to leave well alone - and we're a very small, not-for-profit community organisation which can't afford to carry much in the way of spares, and certainly can't afford to replace things for the sake of it.(3) Any radio card (and more so higher power cards) are very intolerant to poor RF load/connections and will blow, have you replaced pigtails, redone N connectors, replaced any link lead to antenna, checked antenna/leads for moisture ingress , checked connectors.
The mountaintop is solar, with voltage drawn directly from the batteries. The far end has 18v pushed 60m up a hill from a UPS.Note - I had a 2 X AP's using XR5 but had low signal turned out to be caused by pigtails mmcx connector not making a good connection onto the XR5 replaced the pigtails and signal increased , i was lucky the XR5's were not damaged.
(4) Is the voltage good and clean at both locations, have you UPS,
To be equally blunt we have neither the resources nor the facilities to pursue a policy of perfection - anything better than dial-up at 2kbps is a bonus. However I take the point that assuming pigtails, cables, etc. will do properly what they are supposed to do and what we paid good money for them to do might be foolish.To be blunt you don’t simply replace a costly component the second time and let it go faulty in that configuration, you load the radio card with a dummy load to ensure it’s working ok then replace with the cheapest radio card at hand, and start a process of elimination-note signal at other end (if you cannot get a signal from the other end at 18kms then setup a temp link a short distance away) and start replacing leads (pigtail, link lead, even antenna) if there is increase in signal level that speaks for itself?
I would have thought there were clues enough in the screenshots to tell you that.Where in NZ are you?
Ducting?what are the altitudes of each point? You could be seeing ducting - we see this a lot in Northland when we have very pronounced temperature changes (hot day, clear cold night) and also when humidity is high (over summer)
The R532s were Mikrotik's latest and greatest when we began the network - and none of MT's replacements for the 532 fit the enclosures we bought for them so replacing a 532 with eg a 433 means replacing an enclosure as well which is just throwing away good money. So we'll run the 532s for as long as they last, and if we can't upgrade them because of licencing problems it will be because Mikrotik don't put enough thought into their clients needs.Also R532's are getting a bit old now - we have one or two in production but both of them give us weird results from time to time (especially with ROS4 and newer radio cards)
