I didn't make my own choke. .

I decided to go with an MFJ 915, and if it did anything at all it definitely stopped that annoying SWR warning light from flickering while I modulated even though my SWR was 1.1:1.

I assume it was stray RF getting into my shack from the coax (feed line).

It most likely was causing other problems. I couldn't tell you exactly wha all those problems were, but I did notice a lower SWR.

I'm assuming it actually did not lower my SWR just stop straight RF from giving me false readings.

It definitely was worth the $30 + that I paid for it.

If for any reason someone cannot make their own choke (air wound) don't hesitate to purchase an MFJ 9:15.

It absolutely did, and does work (for me).
