Lost 2 Denver stations this week, help please?
Here's my report:
http://www.tvfool.com/?option=com_wr...9038abdefeb1b4 We have a Clearstream 4 Ultra Long Range, installed I think in 2017. 6.1 (PBS) has been hit or miss for the last month, but we know they are upgrading their transmitter (http://www.rmpbs.org/rescan/) and have been able to get it back by rescanning, at least every couple of days. Now it won't come in at all. Two days ago we lost 7.1 (ABC) which we've never had a problem with, since 2016. Rescanned several times since then and it's not coming in. I just found this: https://www.thedenverchannel.com/new...tv-on-april-13 But we've had it with no interruption for years. Now it's gone and won't come back. We just ran a scan, usually we have about 60 channels but right now it's down to 40. |

https://www.rabbitears.info/market.p...&callsign=KMGH https://www.rabbitears.info/repackch...=&lss=&status= This is an image of your report: https://forum.tvfool.com/attachment....0&d=1556922332 Here is a report from rabbitears.info that shows two ABC transmitters that will display 7.1 for ABC on your TV, KMGH and possibly KZFC-LP: https://forum.tvfool.com/attachment....1&d=1556922372 KMGH is on VHF-High real channel 7. Your antenna only has a simple dipole for VHF-High that doesn't have much gain. KZFC has been an analog channel on 26: https://www.rabbitears.info/market.p...llsign=KZFC-LP but they they have a construction permit for a digital transmitter on 26: https://www.rabbitears.info/tvq.php?...ms&facid=67530 Maybe forum member Tower Guy can figure it out, he is a retired TV station engineer. |
Have you contacted KMGH, Denver's 7 to see if there are
issues on their end???? Ditto for your Denver PBS station. Since you are considered "fringe" for most Denver stations, any issues on your end or their end could be causing the changes in reception. My experience tells me that since both stations are telling you to rescan, it probably is on THEIR end........ One or both stations may now be sending out a weaker signal in your direction. That could be temporary or it could be permanent. |
I suspect a problem at KMGH’s LPTV station in Fort Collins. Both KMGH and the LPTV station would appear as 7-1. I doubt that your existing antenna is capable of picking up KMGH on VHF from Denver.

Do you have the C4 (UHF-only) or the C4V (which includes the VHF dipole that clips onto a reflector)?

The "V" of the 4V would seem to indicate that you do have the VHF dipole for real channel 7, but we want to be certain. |
If your antenna has the clip-on box with the black horizontal "rods", it's the "V" version.
I suspect that the problem with KMGH will easily be resolved with a simple channel scan once Scripps completes the channel 26 digital transmitter facility, KZFC-LP. It would be a good idea to ask the station the specific question as to when that facility will be on the air. That makes the requirement to receive VHF from Denver moot as the other two VHF stations have UHF channels that are carrying their programming. Quote:

It is interesting, make that strange, that the three Denver VHF stations
do not reach Ft. Collins as well as some of the UHF stations. All broadcast, except KBDI, from the same general area. |
It's not that the VHF signals don't reach Ft Collins, it's more that it usually takes a physically larger VHF antenna to focus reception of those signals.
Many customers are adverse to the larger physical size of the VHF antennas so there is a strong bias towards UHF-sized antennas. When it comes to the buyers at the large retail chains (except home centers), they pretty much won't even consider a conventional stick antenna to put into their stores due to the space required. |

retailers biased towards smaller packaging. My observation that the report listed KMGH, KUSA and especially KBDI towards the bottom. THAT is what I found to be strange. The TV Fool and Rabbit Ears reports are guides and not gospel, not cast in stone as to their accuracy. |

C4? That's only a uhf antenna you should have looked into a Winegrud we7550A,range of 70miles or a channel master cm-3011 range of 50miles combinations antenna set-up like the Fcc suggests in their Website. And both of these antennas are small like the C4 junk!! |

That is where it depends upon the higth of your antenna set-up and your location of course.:eek::eek::cool: |

So, if I'm reading your chart correctly rabbit73, obviously you can have a higher noise floor on VHF low particularly, and still receive a watchable signal than either VHF high or UHF? And almost the opposite for UHF?
Forgive my learning curve rabbit73. When I became a shortwave enthusiast years ago, the first thing I learned was as long as I get above the noise floor with my receiver, antenna setup etc., I could "catch" the signal I was looking for. And the quieter my noise floor the better for weak signal reception. I presume similar for TV viewing? Thanks! |
