Trying to find out which connector is the main on the new SR9 cards or does it not make any difference at all like the other SR cards?
I’ve found all the SR cards make a difference - if you use the MMCX connection on SR2/5 you must set antenna B.
On the SR9, I found however that j6 is B and j8 is A. I am not 100% but when both cards on J6 are set to B I get -56 signal, on A, I get -90 signal (in the same room). Of course that’s leaving the antenna on J6 - so I assume J8 must be A. How confusing? 6 < 8, the 8 looks like a B but it’s all backwards! Just like the channel list I guess.
Have you put any out doors at long range to see how they handle interference?
I’ve been setting up a couple of test units that have rb532s with sr2 and sr9 and they are connected to 19dbi 2.4Ghz panels and 12dbi 900mhz yagis.
I’m doing it this way so I can switch between the 2.4Ghz and the 900mhz to see how much better the sr9 is compared to the sr2.
The first tests will be shooting through houses in my subdivision. Then I’m going to a heavy wooded area with lots of pine trees.
I have to wonder how these cards are going to hold up against interference from moto and trango.
We just ordered five SR9s.. can’t wait to test them out!
From my testing J6 is a and J8 is b.. Can anyone else confirm?

I have a great interference test I’m going to run. I have a Trango 900 AP on a rooftop colocated with a Verizon paging system, which provides a cozy -20db low 900 band chunk of interference constantly. The Trango 900 is barely able to keep up at 2.5 miles. It doesn’t work unless it’s -81 or better signal strength. If this can equal or outperform it, it would be a great example.
Now I have to find the time… 
The main connector is J6
