Iam sure by now some of you should have gotten the new R52H mPCI card. Any possibility of a performance review before I start with another round obsessive-compulsive buying spree ? 
I installed my first ones today.. I haven’t tested 5ghz yet, but they seemed to work fairly well in 2.4ghz.. Signals are 1-2dBm lower than a SR2 which is correct according to the spec sheet..
My only complaint so far is that I wish they had mmcx connectors..
I won’t know if I really like them until I have a few dozen in the field..

Hi Gerard,
Thanks for replying. Do you set the tx power to default or manual ? I guess Iam trying to find out if there is any a bug in the manual tx power setting like the one we have in xr2.
Anyone else ?
I always turn down the power to stay within legal limits and keep the signals in the 60’s if possible.
I’m not sure if I know what bug you are talking about with the XR2’s.. If you are talking about the 10db offset then no, these cards do not have an offset. If you set the R52H’s txpower to 18dbm it is 18dbm output. With an XR2 to get 18dbm output you would have to set txpower to 8dbm.

I just tried it indoor. So far this card work as it should be. Several db below SR, in 2.x and also 5.x GHz. I tried to load the card for 2 days… and still work fine.
R52H doesn’t need any power adjustments, the output power is that what you have specified.
I’ve got a couple of the R52H cards in RB133’s to do a point to point connection over about 3kM or so, I expect we’ll back off from full power but I wanted to have plenty as we need this link to be rock solid. I’d rather spend a bit extra on higher power cards, than have the link ever go down 
Anyways, in the lab, throughput was excellent! I was able to transmit 25Mbps or so through with the RB’s configured to WDS bridging. Signal strength was in the mid -30’s with TX power turned to 5dBm (using 19dBi 5.8Ghz antennas), at a distance of about 10 meters.
