KHPK-LD AND LOW POWER VHF

As I noted over in the AVS Forum, I was trying out a portable television set with ATSC (and NTSC tuning) last night. My trip took, naturally, me to Cedar Hill.

I was amazed, astonished and blindsided by just how poorly KHPK-LD 3 was received in spite of being close enough to the towers to get a sunburn from the beacon lights. :) At the lumber yard/hardware store in downtown Cedar Hill, channel 3 barely locked with frequent dropouts. Over by the Dairy Queen on US-67, it was even worse. By the time I got to Cockrell Hill Road on US-67, no amount of contortions of the antenna would capture KHPK.

The caveat, of course, is that this was using the attached unipole on the Radio Shack Accurian, even when fully-extended, is not ideal for low-band VHF. Still, it was surprising that within shouting distance of the tower that KHPK-LD barely came in.

With the dustup at WPVI/Philadelphia (low band VHF on channel 6). the FCC *MAY* be looking at reviewing the power levels. Perhaps the low power VHF facilities could be offered some relief.

By the way, both K31GL-D/31 and KJJM-LD/34 pinned the meter at all points in Cedar Hill as expected.
 
Would some of the problem with digital channel 3 in Cedar Hill have to do with slopover from the adjacent KDFW nightlight? Might be worth checking again once Channel 4 is gone.

Yup. And anyone who's read my posts through the years knows that I'm enough of geek to drive out to Cedar Hill in late July to see if turning off the nightlight gives KHPK-LD an edge. Watch for a report in about a month. :)

Apparently it did (although KPHK-LD is still a pain in the ass). See our posts over at the 'KPRC nightlight off' thread (which kinda drifted a bit OT toward the end).
 
Well, it looks like everyone's favorite epic fail station wants to give up on LP VHF.

KPHK just applied to flash-cut their old channel 28 transmitter (which has been off the air for almost a year) to digital. I'm pretty sure they have to give up their "digital companion" station on channel 3 to do that.

Can't say I blame them.

The FCC approved KHPK's digital flash-cut application today, so channel 3 will probably be a thing of the past before long. Look for all your favorite infomercials to be moving to channel 28 ::)

Seriously, I'm looking forward to channel 3 going away. I'll be able to put an in-home analog channel there without "snow" from KHPK's digital signal.

Wow...that was a fast turnaround for an app filed in mid-August 2010.

In contrast, the KTVT/KTXA applications of late-May 2010 for a move out to the Richland Tower site on Tar Road have seen no action.

Yes; I've been wondering what the holdup is on that one myself. Another long one is K31GL's application to move to channel 33. It was filed in June '09 and there's still no decision!

It seems like things either get accepted or rejected quickly, or they get "lost" and take months and months.

The musical chairs game continues. KPFW was back on last night but KHPK/3 and KVFW/38 were off....

KHPK/3 is still off. I'm starting to wonder if they pulled the plug in preparation for the move back to RF-28.
 
It's been off the air now for about 3 days. I keep checking 3 and 28 just to see if something lights up.

On a side note, I'm not sure the K31GL move to 33 will ever happen. I think they believed they had too much interference from KDAF when they filed that application. I suspect the positive reception they've gotten from the public to channel 31 has eased their fears.

I hope you're right, because while the proposed move to 33 does include a power increase, it also involves a much lower antenna height, which would be a net negative for coverage.

This application has been stuck in "ACCEPTED FOR FILING" limbo at the FCC for over a year. But if K31GL really wanted it, I'm sure they'd have pushed the FCC harder and/or requested STA for the change, and we would've seen something by now.

KHPK may be on hiatus, but it appears their infomercials are now running on KATA channel 50.4. Videospammers will not be denied!

Looks like the deed is done. The FCC's TV query no longer lists the channel 3 license for KHPK or for De Soto, TX, where KHPK is licensed.

The channel 28 records are still there, even though KHPK hasn't turned 28 on yet, as far as I've been able to tell.

Things have been rather boring in the D/FW market for the past few months. Yet a lot is poised to happen with the KHPK flashcut you cited as well as the eventual KTVT/KTXA changes (and its impact on KPFW). Plus K25FW has the go to light up on 25 and there's the always enticing KSEX... :)
 
Just for kicks I popped over to channel 3 just now and lo-and-behold: KHPK is back!
3.1 has infomercials. 3.2, 3.3, and 3.4 are all three color bars.

Addionally, K31GL has added a blank subchannel on on 31.5. Very odd.

Yep. Why punch in 5-0-4 when you can just punch 3 and get the same infomercials with 1/3rd the effort ::)

KHPK: Now with more color bars than ever before!
 
Seriously, I'm surprised KHPK is back on 3. The FCC already erased the channel 3 facility from the TV query.

Could it be they're just testing the new 4-subchannel setup before they hook it to the channel 28 transmitter and antenna?

Unfortunately, I no longer have any television engineering contacts in the market or with MAKO. It surprised me that they lit up on RF-3 at all given that the CP for channel 28 was granted.

Maybe Trip in VA has an idea about possible legal issues behind this. Is there a rule requiring X number of hours to be on the air? If so, that *might* be why they bothered with the few, the faithful, the handful of geeks even aware of this 300 watter! :)
 
They can be off for 30 days without notifying the FCC. With a notice, they can be off for six months followed by another six month extension.

I don't think they have authority to operate on channel 3 anymore, as that license was canceled when the channel 28 flash-cut was granted.
