>The program is now crashing when i tune or enable tx. Is there a way to look at the crashlog?
Normal answer to that indication is RFI. Solution is effective grounding or connection of all equipment grounds together with low impedance connections. And all that grounded to real ground as usually done in radio stations. In addition common mode ferrites on connecting wires, especially on the USB line, may mitigate RFI.
There has been a lot of discussion in this mail list, perhaps searching RFI helps.
