Heck yeah, I use my amplifier if needed. No reason not to. There is kind of a cult of JT65 and other digital users that somehow think that using anything other than low power is a great offense. They regularly demean other hams for doing this - I cant hear signals when your power is so high - well as someone commented on the quality of someone else's antenna - maybe your inability to hear stations would be improved with a better receiver or operating technique. I was talking to another guy in the 20w club - he belittled the high power guys and cursed them for interfering with his contacts - well I asked - do you have narrow filters on your rig and are you using them? No . Have you tuned up and down from 14.076 to eliminate strong signals ? No, can you do that? Does your rig have a good Notch filter? Duh, I dont know... And the like. Like any other mode you need to know how to operate to your advantage not just lock your VFO and other controls down and stare at your PC.
