[Discuss-gnuradio] Switching of UHD/Raw-Ethernet Driver

I have two small questions...

1. I successfully installed UHD (gr-uhd) following the guide "http://www.ettus.com/uhd_docs/manual/html/usrp2.html"
     But now, I want to be able to switch back and forth between the UHD and Raw-Ethernet Driver. Do I need to uninstall the UHD, or just using (burning the SD card) the respective firmwares would do the trick? I just wanted to make sure that when i am thinking that i am using the raw-ethernet driver, I am not in anyway getting hampered by UHD's presence. Thank you for your response.

2. I am using XCVR2450 with USRP2. I initially just wanted to find out which antenna (J1 or J2 -- connected to RF2 and RF1 in my USRP2 respectively), was defined to be RX and which one to be TX? I found out from a file "db_xcvr2450.cc" that J1 was defined to be RX and J1-TX, however with my spectrum analyzer I found the contrary to be true. Is there an easy way to check, and be able to set J1 or J2 to Rx or Tx in Python? I did search the threads and couldn't find satisfying answer.

Looking forward to your help.
