Your situation seems problematic. The Guide emblem is displaying but we can probably assume you're not actually receiving the programming data. Since PSIP time in DC is pretty accurate, we don't know if you're actually getting the Baltimore clock. Maybe if you detail the sequence you used attempting to acquire the Baltimore Guide, including approximate time of day, someone can deduce what's going wrong. Until you can display the 7 days of Baltimore TV Guide info, you're probably not actually locked onto it.
For years, I owned an Antennacraft self-contained amplified rotating antenna. It was the only one that could pull in a reasonably ghost free signal on most analog stations because it was fairly directional. The first 2 generations of ATSC tuners were mediocre at rejecting secondary signals so I continued using it. Once I started using the TV Guide centric LG dvr, I discovered rotating the antenna could disrupt the Guide acquisition so I replaced it with a silver sensor and optimized its direction for the highest priority stations and left it there.
Is your beam antenna that long unidirectional design? In really problematic locations, that might still be necessary, but the Pal's tuners seem amazing at rejecting static secondary signals. I'm using two Antennacraft HDX1000s spaced 4 feet apart and combining the signals to get Baltimore and DC. That never worked with earlier tuners.
It may be that you will be able to return to The DC Guide with a 7PM zip code reset. But, you might want to wait until one of the others confirms it works at another location.
To repeat what I said in my previous post: reseting back to DC at 7PM has worked on both Pals but a power interruption or any other reboot at the wrong time of day could restore the time skew. In which case, I'll try the same fix
I agree, "problematic" is the right word.
Your comment about rotating your antenna causing TVG info disruption is very interesting. Over the life of ownership of this CM-7000PAL, I had rotated the antenna many, many times, and AFAIK suffered no ill effects (certainly the clock never became inaccurate). But as of last month when all this mayhem started, it may well be that rotating the antenna here may have been more of a factor than I realized. At one point I thought that moving the beam to raise the signal strength of the Baltimore CBS station was critical in getting a zip code change to Baltimore to take effect. I'm no longer sure of this, nor for that matter, what other odd effects signal strength variations may have caused here.
Even though the clock setting screen always says TV Guide, I'm pretty sure that I'm getting only PSIP data since we no longer ever see advance TV show info. Sometimes 2 days of advance data is displayed, sometimes it's only today's info, but some of this variation probably depends on the exact time of day I check. Regardless, we have not seen 7-8 days of TVG info in a long while (again, if we ever did).
My antenna is an intermediate gain beam. It's probably more gain than needed for watching the Wash DC stations, but I wanted it for watching Baltimore (and to some extent Annapolis). It was installed during the NTSC days and those remote cities, especially Baltimore, were marginal and needed help.
A few days ago I swung the beam back to Wash DC and saw no changes with the CM-7000PAL. Still using the Baltimore zip code, the time remained accurate and the TV Guide listings did NOT improve to include future data. Since I had thought that signal strength might be a factor, I wondered if I'd see any changes, but no.
So though it may have been the wrong time of day, this morning I decided to change the zip code back to Wash DC. This is where I started, this is where things have been since the DVR was purchased -- antenna pointing at Wash DC and using a Wash DC zip code. Almost instantly the clock reverted to being inaccurate, almost 4 minutes fast. Since my clock went from perfect to bad so quickly after the zip code change, it sure looks to me like the local CBS stations (WUSA ch 9) is still faulty.
I intend to keep things stable for a day or two and see if anything changes (especially after this evening). Then maybe I'll try a soft-reset (if that's the proper name for the reset which occurs after pushing the power switch for 4 seconds). Next I suspect I'll need to put the zip code back to Baltimore. Even if I still don't get advance TVG data, I hope I can get the accurate clock back.
If anyone has a better test sequence to suggest at this point, please let me know. For instance, I have never elected the function which returns the box to factory defaults. Is that known to perform magic, and if so, for what circumstances?
