Unfortunately, the RS Pro-18 officially changed status from active to discontinued 2/7/2013.
So that means it would have automatically been deleted from being listed on the RS website.
These Pro-18's are out there in VERY slim numbers. If there is a will then thou will get one
There seems to be some on here thinking that the Pro-18 can be upgraded to do P25 x2.
Unfortunately, there is no update to date for this and the Pro-18 may lack the hardware to do it.
Now it's GRECOM cousin the Pro-800 as most on here know can do P25 x2 with the updates.
