A 24" dish just won't work for FTA. It's too small by 1/2.
I respectfully disagree. I can get FTA on an 18" Dish 500. Is it good? No it's not. But it does work to some degree.
A 24" dish will work, it just won't work well, and won't get everything and will not do well with thick clouds and rain. But it should have no problem pulling it the NHK mux on 103W, most of 97W or Cubavision on 30W, as long t as it's with a reasonably clear sky
Would I recommend using a 24" dish for FTA? Absolutely not. But since Byron has the dish and is trying to lock on something, it should work. That's how I came back to the hobby, with an abandonned DN dish and a cheap linear LNBF. It should be seen as just a stepping stone to something better.
Byron, if you have the dish locked on VAKN, move it slightly towards the east, just enough to lose VAKN, and do a blind scan. You should be able to lock 12144 V 20000. You probably won't be able to get 12080 (DW TV) or 12120 (NBC) though
101 and 99 - maybe, but the NHK on 101 is - I think - a bit weaker than on 103. 99 would be difficult, at best
97 should come in, but againt it wont be reliable
This said, the advice of getting a larger dish is definitely good. I would not get anything smaller than 36"/90cm.
123W (KBS), 30W (Cuba and others), 34.5W (a few French channels) might be also receivable on a 24" dish in FL
