All things pertaining to wireless and RF links

I just got a m6e nano board.
URA can't connect.
The problem is that is outputing a 34.5 MHz signal on the TXO pin.
The signal is originated on pin 20 of the module and is propagated through the level adaptor to the TXO pin of the board.
Power supply is 4.2V. The issue is constant over the entire range of supply voltages (3.7...5V)
Anyone encountered this issue ?
Any advice ? (except for buying a new board or a new module :) )

Turns out that the level adaptor on the PCB (TXB0104) was defective and self oscillating. Got some replacements from Farnell and now is working...
