+====== Band Plan With SWR ======
+{{  bandplanwithswr.png?400|}}
+This [[https://github.com/va7fi/Canadian-Band-Plan |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.
+The HF band plan information was taken from \\
+https://www.rac.ca/operating/bandplans/
+The VHF and UHF band plan information is for British-Columbia and was taken from https://bcarcc.org/
+Here's the {{canadianbandplan.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
