Problem with equal power on TX1 and TX2 for ax9

[h0rac]

Hi

I found that my bladerf ax9 TX1 and TX2 ports are different. On TX2 I can transmit signal without extending antenna or increasing RF gain but on TX1 same signal.. requires either antenna to be extended or RF gain to be set higher in order to reach receiver.

I am using GNU radio companion for tests and gr-osmosdr.
