why would Q's operation affect reception of XETV/Fox? They're on 23 for good
-- they were my first transport stream capture last week. I'd say that the
terrain would have more of an effect than an operation 30 channels away.
Since the XHUPN build is internationally notified, changing channels would be
an extreme hassle, due to the notification and publication requirements. It's
not unheard of for such things to take three years; the parties usually only
meet once each year, in August.
I beg to differ about the public notice situation. The Department of State
(Bureau of International Communications BICI) and the FCC publish public
notices about international coordination. They may not have posted them on a
telephone in your neighborhood. ISTR notices when the filings are sent to the
opposite country, and after the approval/rejection.
Just a few minutes ago, on another matter, I quickly found a dismissed
application on the FCC web site that was denied due to mexican objections.
Approvals get the same treatment as to notice.
Why do you use the callsign suffixes of -DT for Mexican stations? What we call
DTT (digital terrestrial television) is called TTD (television terrestre
digital), so it'd be more likely that the suffix would be -TD. But, the
Mexican practice is to give different callsigns to co-owned am and fms (if
there are co-owned tv/radios, they're not in this zone. The SCT (Secretariat
de Communicaciones y Transporte) www.sct.gob.mx.
And, let us not impute that short_name in PSIP needs to be callsign.
Did I ever mention here that XETV had to get specific permission to transmit
PSIP on their then-experimental operation?

CGC #654 has the link to the Experimental license (with thanks to Howard Fine):
http://www.bext.com/_CGC/2004/cgc654.htm
https://svartifoss2.fcc.gov/prod/oet/cf/els/reports/442_Print.cfm?mode=current&application_seq=27881&license_seq=28096
Armed with the Callsign, I searched FCC's OET Experimental Licensing System
database:
https://gullfoss2.fcc.gov/prod/oet/cf/els/
and located recent request to increase power from 30 KW to 50 KW for both Mt.
San Miguel and Black Mountain locations:
https://gullfoss2.fcc.gov/prod/oet/cf/els/reports/442_Print.cfm?mode=current&application_seq=31014&license_seq=31332
WD2XLG is currently listed with 50 KW (peak) CH53 transmitters on both Mt San
Miguel (most San Diego TV stations are here) and Black Mountain (a few miles
from me).
It also shows 60 Watt transceivers using CH59 from Mt Soledad (the other TV
location) and CH 53/56 from two Qualcomm facilities (East end of Mira Mesa
Blvd).
Clearly they are in demo and test mode:

/////////////////////////////////
So now I'm worried about Preamp overload from nearby Black Mtn.
It would certainly complicate receiving XETV-DT (FOX) OTA from Tijuana for most
of North SD County.
Thanks a heap Qualcomm for messing up reception in SOCAL, with apparently no
public notice.
//////////////////////////////
The www.upn13sandiego.com FAQ still says XHUPN-DT plans to fire up on
CH53....coming soon.
I'm thinking that they might want to look for a channel below CH52....and might
have to wait until they convert their existing CH49 analog station.
Or they'll "co-exist" with Qualcomm on shared CH53, after all, most viewers
(esp in S.D.) are on cable and Sat systems.

Here's the latest from Bob Gonsett's CGC Newsletter #711 on MediaFlo. It
confirms Richard's points. Spectrum management along the border is always fun.
It also tends to confirm my assessment (I am not at liberty to disclose where I
heard this) that MediaFlo is just in demo mode.

MORE ON MEDIAFLO'S OPERATIONS IN SAN DIEGO
An individual familiar with MediaFLO's operations in San
Diego (CGC #710) reports that Black Mountain and San Miguel
Mountain are both on the air for the purpose of broadcasting to
cellphones (or the experimental phase thereof). San Miguel has
reportedly been on the air since November a year ago, while Black
Mountain was added a few weeks later according to the letter.
Mount Harvard, Denver and some Boston sites are said to be
completed already. We are also told that MediaFLO is being
looked at seriously in Europe.
While MediaFLO is authorized to use a number of different TV
channels in San Diego under an experimental grant, the company's
continued use of Channel 53 is in jeopardy. XHUPN-DT on Cerro
Bola is expected to light up on CH-53 soon, at which time MediaFLO
will presumably be required to extinguish its operations on that
channel. XHUPN is said to be internationally coordinated on
CH-53.
