[TenTec] Centaur Problem - Any Ideas?

Sun, 23 Nov 2003 12:41:39 -0500

Thanks David!

I had planned to check in with the TT folk on Monday, somehow these problems
only happen on weekends! Wondered if this might be a common problem with these.

I checked it out this morning and it sounds fine and works normally in both QSK
and PTT mode, only usual level of clatter. I do not generally believe in "self
healing" equipment, so will still follow up.

I agree a fuse shouldn't blow, especially while not in transmit mode.
