Channel scan or build channel list by hand?

I have been a Sage user for almost 2 years now and use it for OTA. I never had a lot of luck with channel scan (the rotor needs to be adjusted for some channels) so I always just built my channel list by hand out of the channels I know I can receive. My question is this - since I do not have any frq files for my channel list, perhaps I have not setup Sage optimally. Do the frq files allow the tuner to operate more quickly? More reliably? Anything better? Anything worse?

Thanks.

Anyone? Does the frq file have any value at all?

The frq files ( one for each tuner ) are very important, they hold several values for channels picked up by the tuner ( such as frequency, polarity, etc ... ).

The files are created when you do a scan , if they are empty then that means you did not pick anything up ( mis-aligned sat dish, faulty tuner card , etc .. ).

Once the freq file has been populated by the scan, you can add/remove channels manually from it .

Here is a sample of what a frq file should look like :

Thanks for response.

I understand what is contained in the frq file and how to create one. In my case, I would have to run a scan a couple of times and then merge them by hand in order to get a complete one.

Does having a frq file make anything better? Faster tuning? More reliable tuning?

Note that I have been running SageTV with OTA for two years without a frq file - I have just entered the correct physical channel into my channel list. However, if spending the time to create a good frq file has benefits, I will definitely do it.

Thanks.

This frq file sounds interesting. I currently have a massive spreadsheet that I use to keep track of my qam channels so I can manually add them if I have to rebuild.
