VSWR foldback protection only when min power available #1855

Closed innattar closed 4 years ago

innattar commented 4 years ago

While testing SSB transmit on the MCHF I kept having VSWR protection kick in (blinking TX). This would not happen during tune or if I used a 100% duty cycle mode like FM. After troubleshooting I realized this only happened when the transmit power level dropped. The UI code set precedent for not computing SWR (for display purposes) if a minimum forward power was not met. I took this concept and applied it to the VSWR foldback protection code. I tested this on an MCHF under the same conditions as before and had no issue with VSWR protection kicking in.

Sorry this is my first time collaborating on Github. This PR is meant to be stacked on top of https://github.com/df8oe/UHSDR/pull/1854. Also I should note that I chose to split this up since the two changes were not related and I thought it would be best to have two PRs.

Since that isn't in the main repo yet both commits are showing up in the commit list for this PR. I apologize for any confusion.

Thanks for merging #1854. I have rebase and pushed up this branch so it only includes the one change.
