Do you both have Roadrunner as well as your TWC cable? I think the Roadrunner connection may have something to do with that as well, because last year I dropped my cable but kept my Roadrunner. Turns out I could still get about 5 channels on my TV (just talking analog channels here). I don't have a QAM tuner that I could have checked on, but I am curious if maybe I could have picked up some of the locals that way. I know the cable company must have many different kinds of filters they can use to block certain frequencies on the line. In my case they couldn't completely cap the line because they had to let the Roadrunner signal though. I'm fairly sure either the upload channel or the download channel overlaps with the analog channel 4 signal, because anytime I'm on the computer, I can see whenever I request a new webpage to load because I get interference on the TV (just channel 4 though). I seems to me the other analog channels I was picking up when I wasn't subscribed to cable were in the 60-70 range...so that must be the other area where Roadrunner uses to upload/download info. Does anyone have any idea what frequencies are used for Roadrunner.
The reason I bring this up is because I need to cut back on my monthly budget, so I'll be dropping my cable in a few months (when a roommate moves out). I have a few OTA boxes I can use, but I only have indoor antennas...therefore I get some signal breakups when watching shows. I hope to keep my Roadrunner, and will be in the market for a 37" LCD HDTV soon, so I'm trying to determine if I need to make sure I have a QAM tuner in the TV to possibly pick up the QAM HD channels off TWC. It would be very cool if some of the HD channels are in the frequencies that will still be coming to my house via the Roadrunner connection!
I don't believe my issue was with TW, I believe it was with one of my TV's. I had a lengthy e-mail exchange with a TW tech who finally admitted the channels are there via clear QAM, but TW provides no support for them, because they don't "broadcast" them. And apparently when they say "broadcast", they mean officially advertise the fact they are there. Anyway, since I had one TV that picked them up, and one that didn't, after a lengthy conversation with the manufacturer, they did acknowledge that I had a very old version of the set (even though I had just bought it 3 weeks earlier) and agreed to exchange it for a newer version. I'm still waiting for them to ship it back to me to test it out.
Also, roadrunner uses a very low frequency for upstream (my modem reports 33008000 Hz for upstream) and a higher one for downstream (my modem is reporting 711000000 Hz Locked). For those of you that don't know, you can point your browser to http://192.168.100.1
and most modems will give you some status/diagnostic screens. The Motorola surfboards give you some nice readings on signal to noise and down/upstream powerlevels. I basically used mine to test my signal strength coming in from the cable company, and at several jacks around the house to make sure my cabling was all good.
