622 OTA Tuner (VHF)

[MACSEV]

My OTA tuner has failed in the VHF bandwith with a known strong signal.
The UHF bandwith is fine. Station signal checked OK on a neighbors set. Have done all the usual deleting and rescanning and am convinced that the VHF portion
of tuner has failed. Unfortunately, I can't convince DISH that my problem is for real.
They refuse to RA receiver. (I'll try again tomorrow.)
Has anyone out there experienced the same failure?

What's your Zip code. Is the station transmitting digital in the VHF band?

VIP 622 OTA Tuner Failure ( VHF Bandwith)

ZIP 29063. Station is transmitting in digital (Channel's 10.1, 10.2, 10.3). I was watching it when tuner failed. Station is on the air ( checked my neighbors off-air digital signal)and my signal strenth is the 90's. There is no doubt that I have a VHF tuner failure. This is second day trying to fix and resolve the problem.
If anyone has had a similar experience, how did you resolve it with DISH?

According to antennaweb.org WIS-DT (NBC) is broadcasting on RF41 (UHF)...the channels are merely being remapped to their primary channel identifier (10.1, 10.2, 10.3) to make it easier for the viewer to find during the analog-to-digital transition.

Anyway, it sounds like something may have changed with your local broadcasters (WIS-DT) PSIP datastream that is causing the receiver to fail. Try this, delete the channel (Setup-->HD Locals) and then manually add the channel (RF41), which should refresh the mapping table. Likewise, you can just rescan your locals.

I hope I'm on target with this...hopefully I'll provide a few links before I'm off to cut the grass.

Althought not directly related, I believe these posts will get you in the ballpark (gotta tend to my duties):

He still has WOLO 25.1 on RF 8

My OTA tuner has failed in the VHF bandwith with a known strong signal. ...

The Digital spectrum being assigned to digital TV is in the UHF range and not the VHF range, as I understand it. A biproduct of this action will be to make the portion of the VHF band containing analog TV available for other uses when the analog stations go dark.

I suspect the channels that you are seeing are UHF digital signals that are remapped for display purposes as decimals associated with your old analog station number.

In other words, old Ch 9 in your area might be transmitting its digital content on CH 25 - it would appear in your listings as 9.1

Most of the RF spectrum being assigned to DTV is UHF, but there are still a number of VHF digitals as well. I believe the end goal is to free up lowband VHF (2-6?) and upperband UHF (55-69?) after the analog-digital transition is complete.

MACSEV, were you able to resolve your tuner/mapping problem? When in doubt, a hard boot is your best friend. Also, it's always a good plan to rescan your digitals every few months.

In a nutshell, your local station has both an existing analog channel (old TV channel) and corresponding digital channel (new digital TV channel) - the RF is nothing more than a Radio Frequency assignment by the FCC. In my case, my local ABC has been assigned the following:

Analog TV: 7
Digital TV: 39
Remapped: 7-1

Channel 7-1 is nothing more than your digital tuner remapping channel (RF) 39 to what you know it as. In you case, your local channel (RF41) is being remapped to 10-1 for your convenience and 10-2, 10-3 (subchannels). Remember, the 622 receiver only has a digital tuner...it will not receive analog TV channels.

Also, check out the following sites and you will see a clear picture of DTV in your area:
