I have had 2,sold one still have the other.
Set you key at 40 to 50 watts on high and let it go,anything much lower then that will cause your quality of audio to suffer. This radio is not going to be an audio monster like the Galaxy Saturn Turbo was nor was it meant to be.
You should see around 150 to 200 watts AM ( mine talks around 150 to 175 as do most of em ) and around 125 to 150 ( mine is around 150 ) SSB from one that's setup to be clean. You see anymore than that then most likely the radio has been clipped/tuned the wrong way and will sound like poo on SSB. Most techs only tune these things ( or any other export radio for that matter ) up on AM just to get those big...oh wow dosy watts and dont touch the SSB so you will know the first time to try and talk SSB if it was done well or quickly!
You will not hurt the power supply running a high (50 watts but no more ) key on these radio and they will not get hot,that's what the little fan built inside the radio is for. The one i got 3 years ago is owned by a friend who has ran the radio at a 50 watt key ever since he got it from me and the radio still works just as it did when new. And believe me. This guy is long winded so if it were going to blow up then it would have by now! I also run mine at a 50 watt key and so do 2 other guys that i know and none of us has had a single problem but........these radios are all well tuned by a professional......you get one tuned by Joe blow and i would not be surprised to see it start blowing smoke for real!
Remember:regardless of what you have been told. Big swinging like a windshield wiper radios are not the way to have a good sounding radio but rather a good way to have a shatty sounding one, you try that stuff on a 2995 and i guarantee you it will sound like crap!
