Well, the HR34 installation came off mostly without a hitch, even though I immediately realized I was going to have a bit of a challenge with the initial technician who arrived when I mentioned terms like “OTA,” “diplex,” and “AM21,” and his eyes just sort of glazed over. In any event, I explained to him that I did not want to lose any existing functionality, specifically my diplexed OTA capability, so I suggested that he call his supervisor for advisement when he became resistant to my suggestion that we add a SWM8 to the existing system in order to gain the additional tuner capacity we needed, rather than pulling the existing SWM8 out and replacing it with a SWM16. To the supervisors’ (plural---as two of them actually arrived at the house) credit, although they were extremely skeptical that the nine tuners could be served properly by two green-label splitter-connected SWM8s, they were both very willing to listen and learn as I told them that if it didn’t work as I had described, they could simply leave me a SWM16, which I would install, I would sign off on the work order, and they could be on their way. A quick call to DIRECTV technical support, who agreed that my proposition was acceptable, and we proceeded with the installation, which I led after describing the parts and accessories I needed from the trucks. As a very important side note, I am absolutely certain I would never, ever have received this type of buy-in from Comcast, Dish, or any other MVPD with which I familiar, and it is one of the many reasons I have remained a DIRECTV customer (and shareholder) for so many years. Long story short (I suppose it’s too late for that), to the near-amazement of the two supervisors, everything worked as expected, with one lone exception, and they actually took pictures of the final product, so they could hold a training session at their shop. The one issue I have is that when attempting to view local OTA channels 2-x (which are virtual 2-x, but RF 12-x) over the AM21-equipped HR34, the picture pixelates and freezes every 3-4 seconds, behavior that can also be viewed and verified on the HR34’s antenna signal strength meter, which fluctuates from the 95% level to 0% at that same 3-4 second interval. Although RF locals 11-x and 13-x are also active in my area, this issue occurs only on this one channel and is not exhibited if I use the TV to direct tune the channel using the same OTA input that is connected to the AM21, nor does it occur on my HR2x boxes, both of which are configured similarly with AM21s. Additionally, as the whole purpose of this exercise was to maintain my diplexed OTA capability, I use Ethernet alone (no DECA) for both MRV and Internet connectivity on the HR34 and both of the HR2x boxes. So, is what I am seeing here a product of the HR34’s internal DECA “broadcast” that never gets turned off? If so, does a band-stop filter at the HR34’s SWM input remedy it (anybody have an extra band-stop filter lying around they can send me to try?)? If that’s not likely the cause, any other ideas?
