Well, I don't write firmware for a living, but I do know electronics and |
| 11 |
I do know the stated reason for having these firmware blobs at all - to |
| 12 |
comply with legislation in the respective countries where the device is |
| 13 |
sold. |

The RF front end consists of amplifier and filter stages and possibly |
| 16 |
other stuff. The gain of the amplifier stages can easily be made |
| 17 |
adjustable under CPU control, so if a designer plans to do that, it |
| 18 |
would be trivial. Whether they currently actually DO that as opposed to |
| 19 |
it merely being easily possible is a question for someone else to |
| 20 |
answer. |

If that person is you and you know for a fact it is not done that way, |
| 23 |
then I shall stand corrected. |
