WBPX-DT
- Thread starter alg2468
- Start date
Well.... in fact, WBPX-DT (Channel 32) is on the air. More than likely, they are running at reduced power in preparation for their full-power operation. That's expected. Most of the DT's are on reduced power until their permanant operations are in place. I've had no problem getting WBPX-DT at home, in Whitman, MA.
They do not yet have a permit. They have an application for increased power which has not yet been approved. As such, I doubt they're getting ready for anything.
If they're at reduced power, there might have been an equipment failure or they could be doing tower work of some kind.

Leaf attenuation (was Re: WBPX-DT)
In addition to what I wrote about earlier, regarding the signal from WBPX-DT, it may be also an issue of blooming of foliage in the trees. Once the leaves come out, VHF/UHF signals have a tendency to be attenuated down somewhat, by several db's as the signals can be absorbed by the leaves in the trees. I've noticed that my signal from WJAR-DT (especially 10.2, RTN) is beginning to drop somewhat as soon as the leaves begin to bloom. I may have to add another 5 to 10 feet of mast to keep RTN available for me. I hope that when WJAR-DT moves to the top of the tower, it could improve my reception in spite of the signal attenuation from the trees.
This might be the reason you're not getting WBPX-DT as well as you as you should. Double check your antenna as well.
Good luck,
-Pete

I'm using an amplified indoor antenna for my DTV-to-analog box on a tabletop TV in Methuen, MA, and lately, New Hampshire has been giving me fits. Channel 9's DTV, channel 59 was previously ok, now it's shaky. For a while I was getting all four of the channels riding on channel 33, now thay're all no signal. And WENH-DT 11 came in pretty well when WENH-TV analog channel 11 went away; now most of the time, I get no signal for them too. Nothing like this is happening to the Boston-area powerhouses: WGBH, WBZ, WCVB, WHDH 1&2, WFXT and WGBX (yes, WGBX is a powerhouse strangely enough, but WSBK-DT, not so much. I can't watch "Jeopardy" some nights). And the Spanish-language twins between route 128 in Worcester are blasting away. The trees are blossoming right now SOUTH of where I live, not north so that can't be it. It's a puzzlement.

according to your post, (dated 04/29/09) you mention its been gone for almost a week.
What change might have happened a week ago that would possibly affect your reception of WBPX 32?
Wait, I know a possible answer! A new high powered 31 signing on! WFXT-DT fired up the new high powered 31 UHF
on 4/20/09. I would wonder if your receiver is being horribly "de-sensed" by the new high power signal. I've seen this rather frequently with adjacent higher power signals causing issues to 1st adjacent lower power signals. If youre in a spot where you are getting bad multipath from 32, the low power 31 wouldve never affected you before, but the new 31 would nail your receiver. I checked on a spectrum analyzer last week and 31's signal is well shouldered and looks good. It's not causing issues in 32 that I could see in Warren, RI. So look into your antenna (change orientation, increase height, decrease amplification) and I bet you'll find your answer.

Necrat, you are a genius! That's probably why I'm having trouble receiving WBPX-DT. I am receiving WFXT-DT with around 90% signal strength now since the power increase. I tried moving the DB4 antenna outdoors (it was in an attic next to a large window) in the center of my backyard for testing and I did receive WBPX-DT (but at less than 50% signal strength),and started to get WYDN-DT 47 (but at only 25% signal strength), with a Venturer converter box (other boxes I also tested - the Zenith and Digital Stream boxes - received the signals but with a slightly lower signal). No signal at all from WWDP-DT 10 - even though it's only 25 miles east. So I may have to increase height of my antenna to get the stations. And I also believe the increase in foliage that occurs every spring is part of the reason for the decrease in reception, too.
