I know this was discussed among other things in an older thread, but I wondered if it was ever resolved. I recently started putting up the 119/129 single dish in SE Ak., and have had no problems with a bunch of 622's and 612's. I did two 722's today however and the 129 column is blank. The details say there is a good connection, the LNB is recognized, but it says no signal. This is with a DP34 switch. Thanks for any info.
