Re: [WISPA] 5.8 GHz PtP - weaker RSLs

2005-08-03 Thread John Scrivner
Is there anyone who is using anything other than Trango who sees this 
same issue?

I saw no changes in my 5 ghz stuff.   Solar activity would have an impact
here too, right?   how long does the influence last?

Looking at this page shows some data http://www.n3kl.org/sun/noaa.html



Thank You,

We had some Trango weirdness overnight also. We had 3 different links go
down at different times overnight but I do not have any specifics of why
at this time. Where were you seeing this trouble?

 Good Morning, WISPA.

 We have witnessed a decrease in five (5) TrangoLink10 5.8 GHz PtPs
 Received Signal Levels overnight. These links are deployed in various
 geographic locations with an average 12 miles of separation between
 tower sites. These links have been active for at least a year (some
 longer). A decrease anywhere from 3 to 8 dB has been recorded in the
 RSLs with the exception of one (1) link which has had a 7 dB boost in
 signal.

 Weather this morning is about the same as yesterday’s weather. Clear
 and 72 degrees.

 Did anyone else see lower signals this morning? This is a weird issue
 to wake up to.

 Thank you for your support.

Solar activity is often blamed for trouble.  And it sure could be.  I've 
heard of radios that looked right into the sun at a certain time of day and 
year.  They'd run great till things were lined up just right (or is it just 
wrong?  hehehe) and then, poof, crappy service.


Usually it turns out to be something else though.  We don't see much 
multipath but it does show up from time to time.  Especially on longer 
links.  Sometimes people work great till the farmer cuts the fields half way 
between us.  Or it'll be fine till it rains on the cut field.  Or it'll work 
great till evening when the heat inversions kick in and make that ripply 
effect you see on the highway.


Or it's just gear that's got a bad solder joint and the heat hits things 
just right to move a connection.


I've even heard of the center conductor in a coax cable expanding at a 
different rate from the outer jacket and getting pulled out of the female 
end on a connector.


If it's a multipath issue the thing to do is to move the radio up (or often 
down) by a foot or two at a time till you find a location with higher 
signal.  I've seen several DB gain from moving systems down by 3 feet or up 
by 2.  I even had one across from a lake that had to be 2 feet of the ground 
to get a good steady signal.  Go figure.

I think too many of you are keeping track of too 
many things! We build in a fade margin so that when this happens (as it 
naturally will) we can deal with it automatically.
