My netid has recently change the frequency to 378250 which presents me with a new challenge.
I am running Black Hole 3 on a DM800. This image only allows for three digits in the Frequency field in the Manual Scan menu and you cannot set the Frequency scan size (khz) to 00250 in Tuner setup menu.
Which gets around the problem on other images.

Q1 Does manual scan pick up its parameters from a file which could be edited?

Fortunately cable scan still works but it takes ages to chug through all the frequencies before it finds any channels.

Q2 Does cable scan get its frequencies from a file, which could be edited to mine at the beginning of the list or does it generate them via code.
