I never understood all the fuss about the 7300's relay clacking and fan coming on whenever PTT is activated. To the extent that people are replacing the fan and putting insulating material on the relay.
I have two 7300's, and use them extensively in contests, semi break-in on CW, and VOX on SSB. I imagine QSK might be bothersome, but that's not my preference. I do wear over-the-ear headphones, and the relay/fan noise doesn't bother me at all. Even without headphones, not enough of a hinderence that I'd perform modifications/replacements on the radio.
But I guess it's all in one's perception of tolerance...to each his own. And in all honesty, I'm 74, and my hearing is certainly not what it used to be. Eh, what'd you say
