Steve - sorry I missed this thread, am on vacation this week - but if you have any questions on the license, etc. hit me off-list.
I would add that it is certainly odd that any radio would allow the user to drive the power past the distortion level at any modulation - one would have to wonder how they could possibly meet the FCC mask in these situations. We are constantly seeing suggestions on various forums for the user to "reduce power to stay in highest modulation". Why isn't the radio setup to do this automatically? Everything else till now has a max power per modulation. ________________________________ From: Af <[email protected]> on behalf of [email protected] <[email protected]> Sent: Friday, August 18, 2017 10:31:51 AM To: [email protected] Subject: Re: [AFMUG] Figuring out what our FCC application says Probably due to linearity issues in the power amp section. Higher order modulations are harder to amplify without distortion. There are methods like pre-distortion to help but that gets pricy.

I’ve got one link on a tower with multiple 5GHz Ubiquiti and I think Cambium sectors on it. This link is 50 miles and I haven’t seen an issue. As for the power issue, once you get above 23dBm I think (have to check the specs), it starts lowering the modulation rate the same as any other radio. I can go back and check some of my links I have up but since all of them are under 23dBm anyway, it hasn’t been an issue.

If 5ghz was interfering, I would assume it would show up on the spectrum analyzer, and it doesn't (although the first radios that we got replaced did show abnormally high noise floors... so it wouldn't surprise me if that was 5ghz leaking in)... but being upconverted chips, I can't help but wonder. I don't think it's too hot, because our other link is at somewhere around -41,and it's running at higher modulation. I think I do have the tx power set a little lower on the other link though, so I guess that could be making a difference. I wouldn't call these radios junk, but they're no SAF.

If this is a garbage chip like that i dont want this gear. I wasnt behind the purchase, i want saf, i like saf, saf support is awesome, everyone in the saf sales channel has been awesome, even the saf guy who doesnt work for them. I got into junk gear im going to regret, didnt i?

Prior to "experiencing" a B11, I'd never used a license radio that could not modulate at the full modulation. bp <part15sbs{at}gmail{dot}com> On 8/17/2017 9:08 AM, Rory Conaway wrote: Steve, the interface is far more functional and simpler than most of the other licensed links. I can’t even get real-time bandwidth numbers out of them in the GUI’s which is kind of pathetic. The B11 and the Cloud are far more useful.

Trying to configure this, Im not sure what channel settings to put in. I went to the application, I see the centers, but no size. Is there a code on here that tells me what channel size we are applying for? And I notice the Application says the radio does not have ATPC, I thought these did, maybe im wrong
