Hi,

There were some changes in October 2008 in dvb-t multiplexes in Czech
republic, so here is the new one.

Can you please try to find out the actual values instead of "AUTO" there?

Thanks,

Christoph

Or, a quick search (with no background) shows this frequency
is in use at Usti n.Labem (north-ish; would have to search my
maps to quote actual antenna distance and view terrain and
predict if 100kW ERP would cover those 50+km), but I see
nothing using this frequency in the area of Praha -- at least,
not in the two results I looked closely at.

Can you tell me what stations can be received on this frequency,
so I can say which multiplex it is, and then, I could possibly 
provide actual modulation parameters as published?

Oooh, replying to myself.  What an egoist.  UNFIT TO DRIVE
ON THEE INTERNET.  Shameful.  May as well write a novel
of nothing but talking to himself.  GET A ROOM!

Relying on g00gle cache with results for `dvb-t praha', it
seems that ``dxradio.cz - přehled DVB-T vysílačů v Česku''
lists frequencies in use at present, and ``DigitálníTelevize.cz > 
Pozemní digitální vysílání v České republice'' lists planned
frequencies -- possibly modulation parameters are linked from
the latter, I haven't yet checked, but Real Soon Now I should
map out a cz-all file comparable to my Baden-Wuerttemberg file
to get a better overview...

According to my dead-tree map in ``Poznavame Ceskoslovensko 1.'' 
the tower for Usti n.L. is directly east, or pretty much directly 
north of Praha, a distance about 75km measured by fingers.  Bukova
hora is shown as 683m and shows a tower; dxradio.cz lists the 
height as 662m.

To the south of Bukova hora is Sedlo at 726m, slightly to the
east; I use `lynx' on console as browser and thus rely on my
maps from 1983.  But to the south of that is pretty much clear
sailing to Praha over 200 or 300m terrain, so that in some
parts of Praha I would expect to see a strong signal (I haven't
seen any indication if Usti nad Labem / Bukova hora sends a
directional signal or not) -- particularly at that lower
frequency.

On this frequency one should see the CT and hear the Cesky
Rozhlas channels, as otherwise seen on E53 (730MHz) from
two locations much closer to the centre of Praha.


All this is based on a very quick look at giggle's cache
results.  I may need to correct things, which I'll try to
do by posting a scanfile instead.  But unless I hear that
different stations are received on this frequency, I'll
posit that E33 does not originate near Praha...

Maybe.

Here is the actual map: http://www.digizone.cz/texty/mapy-pokryti/

So for Prague:

mux 1 Ceska televize
http://www.digizone.cz/texty/multiplex-1-mapy-pokryti-ceska-televize/
channel 53, 8 MHz, 8k, guard 1/4, fec 2/3, qam 64, hier none

mux 2 Ceske radiokomunikace http://www.digizone.cz/texty/pokryti-sit-a/
channel 41, 8 MHz, 8k, guard 1/4, fec 2/3, qam 64, hier none

mux 3 Czech Digital Group http://www.digizone.cz/texty/pokryti-sit-b/
channel 46, ??? (probably the same, it's the same in Brno, where I live
nearby)

mux 4 Telefonica O2 http://www.digizone.cz/texty/pokryti-sit-c/
channel 64, 8 MHz, 8k, guard 1/8, fec 2/3, qam 64, hier none
(only here the guard interval is different as in Brno)

According to the
http://www.digizone.cz/texty/multiplex-1-mapy-pokryti-ceska-televize/  the
channel 570 Mhz (channel 33) is just a weak copy of mux 1 from Usti n.L.

I hope I will calculate correctly, please check.
mux 1: channel 53 -> 730 MHz
mux 2: channel 41 -> 634 MHz
mux 3: channel 46 -> 674 MHz
mux 4: channel 64 -> 818 MHz

You can use the cz-Brno file I posted here a month ago which should be now
commited in the tree. Just replace the frequencies in that file.

Regards,
Tomas

...to generate cz-Praha of course. cz-Brno is OK. :-)

Hi guys,

I'm updating that file according to the digizone.cz information you
mention here; just that I already use the 15.12.08 settings for mux3
(I don't want to update the file tomorrow again ;)

Hopefully it works as expected and thanks,

Christoph
