I recommend Antenna Analyzer, it will show Smith chart. The radio only shows SWR ratio. As long as SWR ratio and Smith chart says 50ohm, then you're good to go.
Thanks for the video. I bought one for $50 at a Ham Fest (s Silent Key gear) I haven't opened it up yet. It has a tag on it that reads Repaired,and Tested 6/13. We'll see what it looks like inside.
I've had good luck with my 989C. I enjoy using it for fine-tuning my IC-7300 (100W) and I needed an external tuner, because I began using an antenna analyzer and wow -- I learned that my fan dipole antenna is impossible to tune very well and needs this type of assistant.....

I have 2 of them. One has been alot better. The other a fellow caught on fire 🔥 😳 tuning a g5rv laying on his h.o.a. roof to be stealthy lol 😆 its never been right since. Then the meters flashed over and detection diodes appeared to have been replace a few times. So i fixed it and it was ok for a while then the meters and diodes had problems. The inductor is iffy. I use a heathkit sa2060a tuner and a older 989c
I have my trusty palstar at1km they dont make that model no more i bought it in the early 2000s great tuner never had problems with it built like a tank like the big heathkit and the dentrons
