Band Plan With SWR
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.
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 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
Update (Jan 30): I don't think I'll do much more work to clean up the code so here it is:
