I have an issue with the QRX100 running t/c.
From camera into QRX is solid; From QRX to TRX900 is solid; TRX900 into 788 is solid, but then the 788 starts running slower within a few minutes. I've tried feeding the 788 from an ERXtcd and get the same problem. In the jam menu on the 788 I can see the RX and TX t/c, and the TX always ends up a second or two behind. I have tried with a second 788, same problem. I've also tried with a lockit box and that's absolutely fine. What's confusing is that timecode is correct all the way through the chain but something is forcing the 788's TX timecode to slow.
This only happens if the 788 is hardwired to either the TRX900 or the ERXtcd, not if the QRX and 788 are jammed and left to run. Any ideas?
