The collection and processing of Wideband HF Channel Availability data is a multi-step process

Basic Steps: Step 1 – Run WBHF_Channel_Availability_Measurement_09042014.exe Step 2 – Process collected files with process09042014.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_09042014.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_09042014.exe

• View while running• Make sure there is a noticeable pause between 29500 and 2500. if not reduce number of FFTs to

244

Step 2 – Process collected files with process09042014.exe

For a 24 hour collection there should be 1441 files

Edit R09042014.bat and file in the first and last filename to process

Run the batch file Run09042014.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

Convert09042014.c/exe and video09042014.m need to be in the same directory as the collected data files. Resulting file is animation.avi
