New VHF ATV Frequencies in Ireland

Post by g6jyb » Mon Apr 30, 2018 5:53 pm

Hi all

Comreg the Irish regulator has been very generous and granted a pile of lowband VHF spectrum to amateur radio

ATV is specifcally permitted in the band 54.0-69.9 MHz on a secondary basis at upto 50W / 17dBW
(yes that is a lot of MHz !!)

My thanks to Noel for some helpful background that we passed over to our colleagues in EI
Hopefully it may let you collaborate, or have a DATV holiday over there:)

IRTS News is below and for detail - the Updated Irish Licence:-

best regards

PS Meanwhile RSGB is working to ease the UK access for 70.5-71.5...

Additional Frequencies
In December 2015 ComReg published a Draft Radio spectrum Management Strategy 2016-2018. The Society responded with a comprehensive submission to this draft and a summary of this was published in the March 2016 edition of Echo Ireland.

In June 2016 ComReg published its final Radio Spectrum Management Strategy 2016-2018 and indicated its intention to grant some additional spectrum to the amateur service. This has now been done and is in line with some of the requests made in the Society’s submission.

The 70 MHz band has been extended to 69.9 MHz to 70.5 MHz. This is an increase of 275kHz over the existing band of 70.125 to 70.450 MHz and is the full band that may be allocated to the amateur service under the European Common Allocations table.

Further spectrum covering all modes including digimodes has been granted on a secondary basis at 30 to 49 MHz and 54 to 69.9 MHz. The latter band also includes digital television in addition to all other modes. These new frequency bands are listed among the bands available generally to radio amateurs in Annex 1 of a recently revised version of the Amateur Station Licence Guidelines document ComReg 09/45 R4 which is available on the ComReg website.

The new bands in the 40 MHz and 60 MHz regions will, among other things, facilitate modern type beacons in the region of these frequencies as well as moving the existing 70MHz beacon on 70.130 MHz to the section of the band designated for beacons.

IRTS will be producing a local band plans for these two bands in consultation with countries that have allocations at these frequencies and IARU.

The Society would like to express its appreciation to ComReg for the release of this extensive spectrum to the amateur service on a secondary basis.

Interesting news Murray!

Wow - they could run a couple of 8MHz OFDM channels (or a big DVB-S multiplex) - OFDM makes more sense to experiment with sporadic E and other propagation modes - still leaves run for some RB-TV.

Just a pity the antennaes are so huge!

IRTS have followed this up with a remarkably detailed band plan that identifies some ATV slots you may wish to try out if you are travelling that way!

Download: http://www.irts.ie/dnloads/New_Band_Pla ... rum_v1.pdf

For example this one is fairly close to the UK 71MHz experimental band:
60.100-69.900 - Experimental Broadband and wideband video

I think that one of the above links was not pasted in correctly and the other seems to no longer be valid (may apply to both).

Does anyone know the correct source for these documents please?

"Someone" should be experimenting with DVB-T on these frequencies...lots of opportunities for Intercontinental DATV DX records to be broken - at least for one way transmissions.
