The collection and processing of Wideband HF Channel Availability data is a multi-step process Basic Steps:  Step 1 – Run WBHF_Channel_Availability_Measurement_ exe  Step 2 – Process collected files with process c  Step 3 – import results into spreadsheet Additional optional processing  Use python program to examine individual data files  Use matlab to generate a video (AVI) file of the spectrum

Step 1 – Run WBHF_Channel_Availability_Measurement_ exe Perseus does not always initialize, Just try again Hint: After setup, and before collection starts, Raise process priority in windows task manager

Step 1 – Run WBHF_Channel_Availability_Measurement_ exe View while running Make sure there is a noticeable pause between and if not reduce number of FFTs to 244

Step 2 – Process collected files with process exe For a 24 hour collection there should be 1441 files Edit R bat and file in the first and last filename to process Run the batch file Run bat – This will generate results for all bandwidths from 3-24 KHz, May take 20 minutes or so. OutBW.txt contains the BW results for each hour, OutBWA.txt contains the results averaged over multiple days for each hour 0- 23

Step 3 – Import Results into Spreadsheet template

Additional Optional Processing – Python Spectrum plot of a single file

Additional Optional Processing – Matlab Video Creation Convert c/exe and video m need to be in the same directory as the collected data files. Resulting file is animation.avi
