Dell,
I am not sure if there is any issue. Either you have harsh Power control settings or or faulty Radio… for testing a faulty TRX you can disable Power control and check calls on both TRXs should be getting same levels.
If the issue is of Harsh Power control settings and your Quality / Voice quality is not being degraded then you need not worry and and if your quality is being degraded then you should see what your quality window is as even in degraded quality its not increaseing power…
