HMM the rcvr is gonna have a hard time hearing the HD with a STRONG analog signal on the same channel....(didnt think of that huh?) Fill ins can be fed by any method but they cannot exceed the main signal contour..so that doesnt work....a xlator trying to extend a main signal on the commercial band can only be fed by over the air reception....where as a fill in (not outside the main's contour) can be fed by other means...so the idea of 105.3 getting more range by a third party xlator wont work..physics and FCC law doesnt allow it

I think you would have a pretty good shot at OTA capture of the HD1 if the main station was running elevated HD power. -10 dBc is surprisingly robust.
Of course, overmodulating the translator would make things difficult too, so you'd want to keep the deviation legal.
How is the rcvr gonna see the HD carriers with a DFQ signal on channel?? You canna change the laws of physics.. nope ��
The HD carriers reside outside the analog signal.
The receiver would see it the exact same way it does when the analog carrier is turned off completely.
Give it a whirl. Turn your analog carrier off sometime, leave the HD on and turn on an HD Radio.
Come back and tell everyone what you experienced.
I work in radio......I have a 100KW FM with HDs....now if I put a rcvr there to hear a distant station on the same freq, you think its gonna work? YOU try that and report back.....
Unless an HD3 is on the way. The other two iHeart FM's in Houston have one.

Whaddya know! I work in radio too, and have several 100kW FMs with HDs.
We're not talking about a 100kW FM. We're talking about a maximum 250W translator, receiving a signal from a co-channel station running HD Radio, picking the HD1 signal up over the air and rebroadcasting it onto analog FM.
Operating in MP1 mode (standard HD Radio mode) the HD Radio sidebands start 129.361kHz from the center of the analog carrier. This has been the gripe of the DX crowd since day one.
Assuming the translator isn't grossly over-modulating and you're running sufficient HD power on the station you want to rebroadcast on the translator, it should be completely doable, because you're not picking up a co-channel station, you're pretty much picking up data on an adjacent channel.
Inovonics makes a rebroadcast receiver designed to do just this.
Then do it and prove me wrong.. it's not going to work due to laws of physics...the rcvr will be soo overloaded it will not decode the adj HD carriers..nope no rcvr is that selective with a STRONG carrier on channel.. don't know what you're drinking but it ain't happening
Just tuned in again a while ago, still coming in very well at my QTH, Highway 99 and I-45, drowning out KTWL. Heard about 5 minutes of ads, along with several liners only mentioning the 105.3 frequency. AFAIK K287BQ is a NCE translator, are they supposed to be running advertisements?
Also, looks like their license to carry request was granted on Thursday... the license still shows KODA as the primary station, I haven't heard any Dabang programming on KODA or any of its HD subcarriers. They're still IDing as KTBZ-HD3, KTBZ still has no HD3.

A translator may be commercial or non-commercial depending on the station it carries and whether it is in the reserved non-commercial band (88.1-91.9). A translator is always a repeater of another station including HD channels. In respect to commercial versus non-commercial, KHCB is a non-commercial station on a commercial frequency. If KHCB had local translators they could repeat their non-commercial signal or lease the translator to a commercial FM station to repeat the signal of that commercial FM station.
It even gets more complicated. For example, in TV broadcasting, CBN, the Christian network, a non-profit, began with an UHF channel in Dallas/Fort Worth decades ago operating as a commercial TV station. We tend to think a non-profit must have a non-commercial designation with the FCC for their stations, but that only applies in the 'reserved band' of FM radio. So, let's say KSBJ has a translator in the commercial band and they lease it to, say, Sunny 99 to broadcast an HD channel of Sunny 99's. They can even though the station that is heard on the translator is commercial. And if KSBJ purchased Sunny 99, they could operate it as a commercial station just as it is now.

That would be simplified but why would it matter? We have to remember radio is there for the consumer and commercial or non-commercial, it's just another listening option. The FCC knows the classification of each station and they're the only ones that enforce their rules. All of the non-commercial stations sometimes don't fit onto the 88.1-91.9 band. Then what do you do with stations like KHCB that is on a commercial frequency and chooses to be non-commercial?
Interestingly, at least some radio listeners don't know the difference. The owner of an auto repair shop wanted to buy commercials on a non-commercial FM and called to see about that. The person at the station they spoke with said the station did not sell commercials. A few minutes later this person heard a break on the station that featured an Underwriting announcement for a competing auto repair shop. In the auto shop owner's mind, the competitor got to buy commercials but they were denied. I have come across this rather frequently with the comment: they say they don't play commercials but they do, just not as many as other stations. In my mind that tells me the typical radio listener believes Underwriting is commercials. I'm sure that same listener would agree the station airing Underwriting has 'better commercials' when compared to a spot break on a typical commercial station and this is also a factor.
By the way, the Daily Digest shows 'License To Cover Granted' for 105.3. They likely got that Friday or possibly Monday. The Daily Digest usually runs a day or two behind on listing the actions the FCC has taken.

What about 105-3 in Hempstead, is it having any effect on the NW side of Houston?
88.1-91.9 is called the Reserved band...You can have a non commercial on any freq, even AM.....but the lower FM range is RESERVED for non comms......thus the name...
True, and the FM band wouldn't be ruined if the EMFs of the world were restricted to this band for all their stations AND translators.
Checked this last week... was able to pick up K287BQ, with stereo pilot, sitting at the Buc-ee's in Waller, TX... Couldn't pick up KTWL reliably until I got to Hwy 6 and 290.
