[AFMUG] What LICENSED radios have you had fail?

[TJ Trout]

Kind of a curious question to the operators on the list, if you have had a
licensed radio fail, what brand and model was it?

[Forrest Christian (List Account)]

You need to further clarify 'fail'. Do you mean a software failure (aka
stop passing traffic, lock up, needs reboot, etc.), or out and out die?

Im curious also, but am curious what the vendor/manufacturer response was,
both in and out of warranty

Failures could be anything, 3rd party radio head issues, failure due to
lightning, i think the better relationship you have with your vendor the
more apt they are to work with you on out of warranty products. So if you
buy a dozen links you will get better response than if you buy 1 a year or
less. If you have advance replacement, then that is a different story
because you are paying for insurance. Just my opinion...

All parts should go together without forcing. You must remember that the
parts you are reassembling were disassembled by you. Therefore, if you
can't get them together again, there must be a reason. By all means, do not
use a hammer. -- IBM maintenance manual, 1925

So far the only failure has been a Dragonwave Airpair 100 that would drop link in high temperatures. Replaced it with a Dragonwave Duo since I needed more bandwidth anyway.

I did have an issue with the replacement Duo - the internal power supply for the radio can’t handle a short in the outside LMR and it blows out the power supply requiring a factory repair. The LMR400 jumper that Dragonwave supplied was defective and internally shorted. We blew out 2 units before figuring out what was wrong. Since it’s been installed it’s working fine.

I recall a Trango Giga Plus that mysteriously failed on the day it was
moved from one building to another. It was working before it was moved,
so it seems like the installer must have done something
wrong......though it's not clear what. I wish I could remember it
better, but I seem to think the IDU was not transmitting to the ODU. I
also remember wondering if he powered up the IDU without having the ODU
connected, and whether that would hurt it....but I wasn't going to try
and duplicate the problem :)

I also recall a power supply failure on the same product. It was the
Trango brand 1U rackmount power supply. I think on most products that's
the part that's most likely to fail, so I'm not meaning to knock Trango.

Both of those happened on links that were 3+ years old, so the best we
could do was buy replacements.

I would still rate the product as having worked flawlessly. One problem
was statistically likely to happen at some point, the other looks
circumstantially like operator error of some sort.

I am equally curious about other people's issues.

We have had failures on two different Dragonwave radios.

One ODU (AirPair) developed a problem where it would stop passing
traffic when the temperature dropped below 32°.

A second set of radios (Horizon Compact +) with an obscure problem that
was apparently triggered by some kind of data-stream sensitivity.
Dragonwave was able to supply a patch in about a week, but the trigger
was intermittent, and worse, when the link went down, both units would
report the link as "up". We had to put a trigger that monitored the
traffic volume on the backup link; if the backup was passing more than X
amount of traffic, the Dragonwave link had stopped, and we would have to
reboot both the master and slave.
