Hello,
I have FT450-D connected to a trapped dipole for 20, 15 and 10m
Using voice on 15 and 10 m SWR ok and at 20 m roughly 2.
Since yesterday no more possible TX on 15m, antenna symbol is blincking
if I try TUNE, also not possible
Yesterday I was using making QSO in FT8 via SCU-17 with 50W
what can be happened?
Can be rig damaged?

The blinking antenna symbol means that no match can be found. Did you try transmitting (at lower power) with the antenna tuner off and see if it works?

I Set 5 W and push PTT.
It is possible but SWR become at max when I speak. Stay 0 if I am not speaking

0 SWR not speaking = normal because no power goes out
high SWR when speaking = check your antenna. physically get out and look at it, especially connections and traps

Bottom line, if your radio works on10 and 20m, its probably your antenna not the radio
