No. I have not been able to detect a signal from 12.050 TP either for a long time. I did probably over a year ago as I still have the Challenger TV 4 USA station listed in my channels, but I cannot pull that in anymore.
I can find two other TPs (11.995 V and 11.998 V). These are coming in with high 93-97% signal quality for me and are ITC channels (in Spanish).
As for 12.050 TP, nada!
