I'm having some problems trying to transfer some old dats. I'm transferring them going coax in on my 744T. For a few recordings, I'm getting what looks like dropouts on the 744. Just a few seconds with no signal. There aren't any dropouts on the master recording, and they don't repeat themselves in the same places in the file when I redo the transfer. I switched my coax cables twice and the BNC>Coax adapter as well. No luck resolving it. It seems completely random. It's like the 744 just loses the lock on the signal. Has anyone come across something similar?
