This is a list of radios for the OnePlus One (bacon). With the new OTA release, some people may have better signals with the old radio or want to tinker with the new one so here is a list that will be updated to allow users to switch to their preferred radio/modem.
Radios are independent of Android version, use the radio that provides you the best signal. It varies from user to user, there is no best radio/modem Why? Different carriers, different locations, and more. There are so many factors that play into cellular signal so just because a particular radio is the best for someone doesn't mean its the best for you. We can obtain a consensus on which radio performs the "best" for the largest % of users though.
However, see @Vonnegut 's experiences here on modems.
How to Flash?
Simply flash the .zip below in your preferred recovery. If you prefer flashing via fastboot, extract the .bin file out of the .zip file and flash it by typing,
fastboot flash modem <name-of-modem>.bin

To get a feel of what modems are identical and what are not (thanks to @funCrash93 for having the time to display this -- http://forum.xda-developers.com/show...&postcount=163 )
It should also be noted that in Settings -> About Phone, all the versions are listed as MPSS.DI.2.0.1.c7-00020-M8974AAAAANPZM-1.
Confirmed by armitage, they are indeed different with the same baseband version. See here.
