Gee, that is funny that you mention this. There is no real drift problem though, this is a software problem with the brand new version p453 software on a 301-13, also a nice way for dish jockeys to drum up repair jobs/bills on naive grannys, real convient! The day p453 hit the machine it reported drift, took lnbf and swapped it with another that was on 129 dish that doesn't report drift, when installed on 61.5 reports drift, replaced all cables to 61.5 still drift reported, then installed orignal 61.5 lnbf on 110 and no drift reported, must be "drifty" E3 TP problem on dishes side/or a new software bug. Even swapped DP34-21 setup for spare DPP44 and still drift on 61.5, not concerned and not having any dropouts or signal problems with 61.5 so I don't accept what the DDDCs what me to think. But, thanks for your concern. Only use 61.5 when rain fade is on 118. Also noticed with new 2 week old p453 that every transponder on every satellite is now labeled as a spotbeam while some are and some are really transponders for conus, they must have had some real winner break the code in p453.
