OK, I've tried everything I can think of. I took one of the boxes (dealing with 3), took it back to original Fortec, out of the box configuration, then converted it to 2700 again, then lmza, then put on V215. Same thing. 119W, which is straight through (22khz off) works fine. 110W (22khz on) shows no signal. I've taken both the viewsat and the sonicview receivers to the locations the FLUs are at, and they receive both 119W and 110W. I'm stumped. Any ideas anyone? Is anybody else successfully using a 22khz switch with this file? What do you think Stevega? Any input would be greatly appreciated. Thanks guys.
