I think I figured it out. It does probably work. But only the 5.7L versions. None of the other versions. I think it was a fluke, just happened to add some useful gain, but was not designed for it.

My recollection was that due to the odd patch inside the 430, I was never able to make one work. But my website says the 57L stinger will work on OFDM 430 SMs. I am not sure I even have a 430 SM to test with. I think this was an odd error that has crept into the text of my specs over the year, but the line reads “OFDM” and not just 430, so it was not a 430 vs 450 typo. I am almost the only person to write the specs so it was almost certainly myself that wrote it. So, I don’t know. Will the 57L stinger work on a 430? I would bet not.
