[AFMUG] Radio Failure, which is more common

I have an AF24 Link which was humming along nicely, but just dropped 30db on one chain on one end. Since it's only 1 chain, and only on one end, I'm thinking it's not an alignment or infringement problem. Which is more likely to be the failure, that the Transmitter burned out, or that the Rec

Re: [AFMUG] Radio Failure, which is more common

So oddly enough try reversing the frequencies on the two radios and see if the issue goes away, you may have lost some kind of a preamp or other device that’s only in one direction or one frequency. I have seen that before. > On Aug 23, 2019, at 8:18 AM, Nate Burke wrote: > > I have an AF24 L

Sadly we have seen this several times before. Weather radar is extremely sensitive. They use 60 dB antennas and scan in all directions. If you are within 100 miles of them and using their 5.4 channels it is almost ceartain you will be caught. Sent from my iPhone > On Aug 23, 2019, at 6:49 A

Re: [AFMUG] Radio Failure, which is more common

Not AF24 specific, but absent any other information, I always change the xmt side first. Losing 20-30 dB sounds like a blown xmt power amp. Totally deaf could be either side. But maybe someone can add info about typical AF24 failure modes that would supersede this. -Original Message- F

What is the vert/horiz degree on those antennas or is it just one big rotating parabolic dish ? I imagine they would have hundreds of slim sectors of about 1deg each inside a giant ball or dome. On 8/23/19 8:39 AM, Chuck McCown wrote: Sadly we have seen this several times before. Weather rad

Re: [AFMUG] FCC Proposes Fines Against WISPs and Issues Warning to Industry

I personally am skeptical that DFS actually works worth a damn, I think the operable advice is DON'T USE THE SAME FREQUENCY AS YOUR LOCAL TDWR!!! Even with DFS enabled. It's not had to look up the frequencies they use, stay away. -Original Message- From: AF On Behalf Of dave via AF

Re: [AFMUG] Radio Failure, which is more common

When an airFiber radio has signal issues and modulates all the way down to 1x, it stops using chain 1 (hence the signal level drops). It may be that there is some issue causing that direction to modulate down to 1x? On Fri, Aug 23, 2019 at 8:40 AM Ken Hohhof wrote: > Not AF24 specific, but absen

The site I have been to was a rotating parabolic that could tilt. I think it was 50' in diameter. -Original Message- From: dave via AF Sent: Friday, August 23, 2019 7:50 AM To: af@af.afmug.com Cc: dave Subject: Re: [AFMUG] FCC Proposes Fines Against WISPs and Issues Warning to Indust

Re: [AFMUG] FCC Proposes Fines Against WISPs and Issues Warning to Industry

I too am skeptical. The majority of our DFS detection's happen between 7am and 10am and only on northern facing AP's. The closest TDWR to us is 90 miles to our south. I'm convinced our DFS events are false positives due to Cambiums extreme sensitivity that showed up after firmware 15.0.3. Before th

Re: [AFMUG] FCC Proposes Fines Against WISPs and Issues Warning to Industry

WE had on case some years ago that a Cambium 430 with DFS actually chose 5610 as its channel. Gino Villarini Founder/President @gvillarini t: 787.273.4143 Ext. 204 m: [https://image.ibb.co/ctQ7jU/aeronet-logo.png] [https://image.ibb.co/noQeyp/inc500.png]

I read an article once which claimed that to satisfy worldwide electric demand via wind alone would require extracting 100% of the energy from the wind.  That is to say, it would require stopping the wind. -Adam On 8/22/2019 5:25 PM, Bill Prince wrote: I am unschooled in this, but since wind

Their must have been some other assumptions. Total usage is something like 10tw and average wind energy available under 100m is somewhere around 250tw. Obviously you could never capture all that energy. On Fri, Aug 23, 2019 at 11:53 AM Adam Moffett wrote: > I read an article once which claimed

I am sure there will be continual advancements in solar panel efficiencies and lowering of cost per watt. Solar is practical for powering most things. We will always need to fire up the coal, oil, natural gas, nuclear, or hydro for smelting aluminum etc. From: Carl Peterson Sent: Friday,

Re: [AFMUG] FCC Proposes Fines Against WISPs and Issues Warning to Industry

They really should open up a database system where you, or the radio itself, registers to GPS location it’s operating at and enables/disables the use DFS frequencies entirely. But that would mean someone in the government would have to do some work, or contract it out for one gagillion dollars…

Re: [AFMUG] FCC Proposes Fines Against WISPs and Issues Warning to Industry

WISPA actually proposed the database during the discussions a few years ago with the FCC where we nearly lost access to all of the lower portion of 5.7 due to the OOB emissions into the 5.4 space. The FCC rejected the proposal due to complexity (and it was complex - a design for a mouse that e
