HR20-700. My local ABC [KXXV] went digital on the 17th, although I'm not sure that has anything to do with my problem. It has 3 subchannels, 25.1, 25.2 and 25.3.
Last night I was able to watch 25.3, which is their weather only channel. The other subchannels were also working fine. This is all through the HR20. This is *after* the digital switch.
Today I can get the DTV uplinked channel 25. However, when I tune to the subchannels I get "searching for signal".
Here comes the head scratching:
When I check the signal meter it shows 100% on all three subchannels (I can see the tower lights from my back yard at night).
When I use the tv tuner, without an antenna, I can get all three subchannels. It's only when it goes through the HR20 that I lose the signal.
All other subchannels (other networks) are working fine on the HR20. I did a re-scan of the channel guide after the digital switchover, so that's not a factor. [I'm not sure what to call it but I did the antenna setup again]
When I do "Antenna Setup", "Edit Off-Air Channels" it shows the channels in the following order:
10.2
34.1
34.4
25.1
25.2
25.3
34.2
34.3
However, in the Guide the subchannels are in the proper order.
I live in tornado country, so that 25.3 weather subchannel is very important to me. I don't want the hassle of having to switch to the tv tuner for it. Also, DTV isn't yet uplinking the 25.1 in HD, only 480i, so if I want to record HD programs I need access to the 25.1 subchannel.
Any suggestions to solve my mystery?
