Yesterday 15-12010 is the D-day (digital day switch over )though in pilot stage for nationwide TV channels relaying in Thessaloniki. Most of the western part of the city including parts of the north areas including us in Filiro and Retziki are now able to watch the 7 TV channels via 2 transmitters using MPEG 4 compression technology and COFDM mode.
The 7 TV channels are Ant1 Mega SKAI STAR MACEDONIA Alter and Alpha which last year started a consortium called Digea TV to promote the digital switch-over in Greece for the commercial TV channels (separate from the national TV network). Thessaloniki is the second point with Athens to follow in several months but in the first semester of 2010. First press release was on 16-12-09 and all members of the consortium started banners from the 1rst of this year to inform for the digital switch-over that just made from the point of Filipion central part s of the city but on the mountain) but leaving the older main point of Hortiatis (E of the city) still using analogue mode
More for this including two coverage maps in this page
http://www.digea.gr/news/details/3/8.html
As for now 15-1-2010 and 0700 LT the switch-over has been completed using two 'transponders' on 25 and 29 for the digital format, previously used by Macedonia TV , another (?? No info ) as spare while all other freqs use the following notification for this
- In case yor tv set includes a MP4 decoder please re-tune it on TV channels 25 and 29
- IN case you TV set does not have any MP4 decoder , you will need an external decoder
Tested my father in law's TV monitor with built in decoder yesterday 15.1 morning 0700 LT . channel 25 was with 3+1 TV channels in the clear (Antenna , Alpha Alter and spare ), while ch 29 due to some in band-QRM showed halted or low-framed video (channels available MAk TV , Mega Sky Star) , though today signal was 100% . This is possibly caused due to a 2 antenna mixed system used so far to pick signals from the two main transmission systems.
As for the picture , with the TV set is better than using a sat system
And here is a listing as found from unknown site
And here is a listing of he freqs used by the DIgea members
The full digital coverage is expected to be carried out by 2012 or 2015
As per Digea
site , this is the second digital
network system . The first transmission
system has installed in Xylokastro (near Corinth on Peloponisos )3 months ago and the next system will be installed in Athens Larisa and Patra
It should be noted however that the Greek national TV
network ERT is already
transmitting in Mpeg 2 digital format in
Thessaloniki since mid 2007 using
the transmission facilities from Hortiatis in the TV channel 56 using a
special digital package with 3+1 channels (Prisma ,
,and RIK the Greek cypriot national TV
channel)
Update on 10-10-10 !!
Now the digital scene has changed a bit . Now the channels that can be received (in Litohoron )are as follows:

* :
signals coming from Philipion , inside Thessaloniki MP4 format (Digea
network )
Other signals are coming from Hortiatis antenna farm .
IN our area the signals from 778 706 514 are NOT receivable
The transmitter on 706 shows only a DVB-T card for the moment It is there for at least 6 moths
New update on 14-1-11
As on 14.1.11 the transmitter from the Greek national TV on channel 26 has been changed transmission site and frequency:
The transmission point changed to Phillipion (from Hortiatis)
The frequency has changed to 23 ,
replacing the analogue TV channels of ET-3 (on ch 23) NET (of 49)and ET1 (of 39).
But some problems occurred to the transmitter of the other digital package from the national carrier that consists of Prisma /Cine plus /RIK Cyprus/ and Sport PLus with 2-3 signal dropouts per day .
As per 15-8 the channel bundle on 706 MHz has started programs with the channel 4E ie a religious program from private sector. All 4 slots with the sane TV program
IN the western Thessaloniki i found a not new TV channel transmitted from the TEI (tech Institutes in Sindos ) using 1080 HD definition .Signal in Retziki is only 16%
Also :
674 MHZ new with 64% signal with new Nova encoded channels including TV5 and Euronews
754 RIK /Vouli/ DW /BBC News
554 DION (Caterini ) / Euro 1 / Egnatia /Nickelodeon
570 BNTV 1 /test card - from Bulgaria with 86% signal
This is the start day for Digital TV in the whole Thessaloniki
The map is now this way :
ONly two channels still transmit in analogue , the national ERT channel 1 which is transmitted in 05 and 36 and TV100 in channel 44 which is also received OK on mountainous areas
The other digital channels are as follows:
490 |
Et 1 NET ET3 ET HD + 5 radios |
498 |

^ ALTER has
been suspended several months ago ,
--- is just a spare vacant channel
-------------------------------
NEW UPDATE NOVEMBER 2014 & 16
On
November 2014 all frequencies have been redesigned by the state and
the transmission point for Thessaloniki has been fixed to mountain
Hortiatis and the program we could receive in the mountainous points
have been disappeared leaving especially us in the top of the
mountain under very difficult conditions to watch TV .
The
list below is from Litohoron on late November 2014 The list for he
moment does not include the special transmissions of NERIT.

Notices : 24 and 36 have signals with no program . 31 is set with these 4 programs without streams
The terrestrial receiver has shown several strong (90+%) signals on 22 /23 /32/34/49 without any content which i suppose are self hets so i ignore them from the listing. A second receiver in another point shown strong carriers on different frequencies making me to think that they are really self hets . IN that point MRT on 21 could not been found.

* I really wonder why ERT1 has not been added in the list with the hope that they add their most interesting channel ASAP
Channels 36 and 43 were received later after turning the antenna by 90 degs for the best quality making Ch 24 adn30 with less signal. For better results we changed the 3polar Yagi with a "new technology film antenna" for supposedly DTV signals (sic) that introduces a wider reception and higher gain without requiring any amplification I m not sure on the technical background of it but really in added around 3-6 db of natural gain adding up to 6% higher signal level
IN my QTH the signal was always with multiple ghosts prior to DTV.
(add 2-9)
Litohoron same yer for a long residence : there are a few more channels with digital signals but my new android TV cant get them as it does not shown transmitter frequncies:
Zeppelin radio is added in a Greek channel
MRT
-Skopje network with MRT1,2 Sabraniski and a lot of encrypted programs
(Baby TV, Balkan trip, CInestarDM sat HBO1,2 Nasha TV , Top Channel
TV1000 TV shenja and a few radio stations )
BTV -Bulgaria (BNT 1 2 3 bTV Bulgatria on air
Moreover while spectrum analysis yelded the following signal
494-501 -85dbm
518-525 -100dbm
590-597 -95dbm
662-669 -100
678-685 -96dbm
|
Tthere were more than 10 more digital carriers with less than -115dbm filling nearly the whole band but are quite poor to be decoded by the TV leveled between -120 to -105 as made with the SDR's main program.In addition to it most of them are susceptible to fading These measurements are made in morning times

After chickling this android TV to the extreme with its
thousand operations from its veru complex menu, the process of identifying the
signal info is very complex.In the above tablet i added the signal strength and quality as xx/xx radio with signals very variable . All scrambled programs from MRT are shown with middlescore. Radio stations are shown in italics.
on 24 ERT1. is added as backup just in case the signal is not visible in the other freq
MRT netwrk is quite poor to be received , while Bulgarian TV seems nerly lost. sad for that!
