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

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!

On Tue, 2 Dec 2008, BOUWSMA Barry slobbered and dribbled:

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...
