I think I know of an other amp in the same city that might have QADU unit

as me and Warlock56 are in the same city. Down the street TWC recently replaced a BLE87/100 with an MB100 and I have a feeling it has a QAM ADU in it if TWC is now starting to replace the units with digital ones. I think this amp is about 2-3 months old being in place. I think it feeds either my local 7-eleven store or the car care place next door to it.
a while back about 6 months ago I was watching channel 70 analog and all of a sudden the channel changed to an dead signal with snow for a few seconds during a storm likely just a quick cutover to the power supply for a second.
Oh Cypherstream I think TWC did a similar project replacing AGC modules in San Antonio Texas about year or two ago in the CCOR amps there and now channel 70 is a digital QAM on that system so I am thinking TWC used digital QAM AGCs in San Antonio to be able to use channel 70 as a part of the last upgrade moving more channels to digital only. I have a feeling if TWC is doing this in my area it could take at least a year to get the project done if not longer. I think the same thing happened in Wichita Falls as they are CCOR as well and they have a QAM carrier on 70 now.
