No signal after update from original rom

[rault]

I have a XDA Orbit 2 (Polaris) and I have upgraded to udK_Diamond-R8_Polaris_WWE.
Since I've done this I cannot get signal on orange. When I set up to manual network it finds Vodafone and O2. I have inserted an O2 card in and it works, however signal is very weak. In other words, the signal has decreased dramatically.
Does anyone how can I solve this problem?

What radio are you using and did you update the radio ass well? I tried UDK's rom and didnt see any difference. Technically (correct me if I'm wrong anyone) updating the rom should not affect the radio or its signal unless you flash a rom that includes a different radio.

Before flashing to the Murata it would help if you could supply this info, it might just be a settings issue.
