How to check signal strength and quality (DVB-T only)

1. Run the program by double-clicking on it. It will automatically create a log file called ScanChannelsBDA.log in the same directory as ScanChannelsBDA_UK.exe. 
   If ScanChannelsBDA closes itself almost immediately without an error message - you don't have any TV card drivers installed correctly.
2. If you have multiple DVB-T tuners in your PC, or a dual-tuner DVB-T card, you will be asked to choose which tuner to scan:
   
3. Next, the main menu will be presented:
   
4. Choose a scanning type. The main options to use from the menu are as follows:
   • 1. UK and Europe (All Frequencies) - Performs a scan of all UK frequencies (UHF/8MHz). USE THIS REGARDLESS OF COUNTRY
   • 6. Graphical (Single Frequency) - Checks single frequency scan (as specified) and produces minimum, maximum and averaged signal strength/quality statistics indefinately until stopped
   • 10. Exit - Closes ScanChannelsBDA
   Choose from these by typing the desired number followed by the ENTER key.

1. From the main menu, type 1 followed by the ENTER key.
2. The program will then begin to scan through all frequencies. When a signal is locked, you will see a list of channels on that frequency.
   

1. Start by typing 6 followed by the ENTER key.
2. You will be prompted for the Frequency to check - enter this is kHz without any commas or decimal points (i.e. for 762MHz you would enter 762000).
3. You will be asked for Bandwidth - for the UK, enter 8.
4. If you specified a frequency on which there is no signal, ScanChannelsBDA may retry whilst displaying "Please wait" for some time.
5. If a signal is found, then you will see the signal statistics screen:
   
6. Press any key to end the signal statistics and return to the main menu.

• Quality High - Signal is good
• Quality Low - Signal is bad
