I seem to remember reading somewhere that installing an XR2 in an RB433 effectively makes one of the two remaining slots unusable because of the thickness of the card… although I can't find this information anywhere now (a pointer would be appreciated).

Is there enough space on an RB433 for two XR2 cards? (I don't need three radios on it anyway.)

u can have 2 xr2 if the casing ia slightly big. n u place 1 on the top slot and 1 on the last slot.

how ever 2 xr2 together in the same box would mean lot of noise. u can rather have 2 R52h if u really do not need so much power like the xr2's.
