Your data confirms with that device that you're now getting a lock 100% of the time in a consistent time period. I actually got my hands on my own HVR-1600 tonight, and with the mxl5005s datasheet I got from Maxlinear last week, I will be looking at lock performance in general for that tuner. Thanks again for doing this testing. Mkrufky has indicated he wants to do some testing this weekend, and assuming that happens I will submit a PULL request first thing next week. Devin -- Devin J.
