 ====== Band Plan With SWR ====== ====== Band Plan With SWR ======
-{{  :blog:2021-01-16:bandplanwithswr.png?300|}} +{{  bandplanwithswr.png?400|}} 
-A few weeks ago my external tuner kicked the bucket and the portion of the HF spectrum that I can now use shrank to what my internal tuner can handle under a 3:1 SWR.  I got my RigExpert antenna analyzer out and started hand writing the SWR on my printed copy of the [[https://wp.rac.ca/rac-0-30-mhz-band-plan/ |RAC HF Band Plan]] when I thought of my next Python project: Recreate the Band using ''matplotlib'' and overlay the SWR from the RigExpert ''asd'' files.+This python script does two things: 
 +  - It reads all .asd output files from the Rig Expert that are placed in the same folder as this script and calculates the VSWR as a function of the frequency. 
 +  - It recreates the band plan for all bands from 2200m to 70cm and adds VSWR graphs on top of it.
  
-After a few days of reading about ''matplotlib'' and playing with a few examples, I managed to put all the pieces of the puzzle together and created my first (incomplete) graph.  It's got all the essential elements, but I just need to finish re-creating the band plans, annotate them properly, tweak a few things here and there, and clean up the code.  Here's the {{canbandplan.pdf |output of my G5RV and GP9}}.+The HF band plan information was taken from https://www.rac.ca/operating/bandplans/
  
-I'll post an update and publish the code when it's done.+The VHF and UHF band plan information is for British-Columbia and was taken from https://bcarcc.org/ 
 + 
 +Here's the {{canbandplan.pdf |output of my G5RV and GP9}} so far: 
 +  * The top of the band plan graph corresponds to SWR = 1:1, where the first dotted horizontal line is. 
 +  * For HF, I also added a horizontal line at SWR = 3:1, which is where my internal tuner can reach. 
 +  * And the top of the graph is at SWR = 10:1, which is where most external tuners can reach. 
 +  * The red graph is the SWR curve.  If it's not showing, it's because it's above 10:1 
 + 
 +<fc #ff0000>Update (Jan 30)</fc>: I don't think I'll do much more work to clean up the code so here it is:
