I have two ts 440's, a ts-850 and a ts-50 and all of them talked on 11 meters when I bought them. My ts-50 would not talk AM on 11 meters. Reports said it sounded really bad. I went into the menu and turned the audio down to "low" and turned the power to 10 watts and that worked great.
I would suggest running lower power and audio with any of the HF rigs. I talk mostly SSB on 11 meters.
