Elder, keep in mind that HDVR1100 is Mpeg2. 125W duplicates all MPEG4 HD signals in MPEG2 SD. You will be able to watch all except Montana PBS. MPBS is in MPEG4 only. MicroHD or HDVR1200 will work perfect.
A scan with the Traxis 3500 yields nothing on Ku-band. All the PBS signals, according to my MicroHD, are DVB-S2, even if they are marked "Standard Definition."
