[linux-dvb] RE : Tuning Regression on Hauppauge Nova-T Stick forjust one channel (driver dvb_usb_dib0700)

Your failing channel is VHF channel 6 while your working channels are UHF.
Is the Hauppauge Nova-T Stick supposed to work with VHF?
Maybe an antenna or other reception-related problem with VHF?
