Yes, you are correct, David.  That heat sink is so massive, that for =
SSB, it is probably a little overkill.  I do hope it is pulling air out, =
not blowing it back in though.  If someone has reversed it, thinking it =
would be better, you might turn it around so it pulls air out of the =
cabinet before you start transmitting with it again.

  I use my TR7-A mostly for short-wave listening, so I've unplugged the =

Am I correct in assuming that this fan is only required if I'm =
transmitting?  Any advice would be appreciated.......73,  David
