In my opinion, a large part of the DTV problem is the fact that so many TV
stations are changing the RF channel for their broadcast. Many are changing
tower locations and antenna elevations as well. These stations decided to
keep this information essentially to themselves. Their feeling was

It would be nice to have an updated TV chan freq list so I could see what kind

The RF channel frequency allocations themselves are not changing - just
which channels/frequencies the stations are utilizing for their DTV
broadcast. MOST stations are moving to UHF channels, but some will remain
in the VHF band. You need to check the market area where you are receiving

There's no change in how the channels are divided up. The frequencies are all
remaining the same, just where the digital vs. analog signal has changed.
Generally, the announced channel number is for the analog signal, with the
digital signal in another channel slot, until the official

Not quite right. The majority of stations are staying on their assigned
digital channels. It is EXTREMELY expensive to change channels, so unless
there is a compelling reason to move back to a station's analog channel, most
are staying put. Out of eleven stations in the network I'm CE for,
I do not believe that any of these cable assemblies utilize double shielded
coax. If someone knows differently, please let the group know.
Personally, I'd use some RG-400 silver Teflon coax. You can get crimp
chassis jacks for it, or use a hood. Short center pin Teflon phono plugs are

Brian,
How did you detect the carrier? If you used a handheld radio in the
vicinity of the repeater, then yes, the exciter's oscillator is running all
the time. Most likely, your VXR-5000 is an earlier model that has
single-shield coax jumpers inside the cabinet. I have a VXR-5000 repeater

Same here in Portland, Oregon; the TV stations on hi VHF will stay there with
