70cms DATV under threat
Posted: Tue Jul 22, 2014 8:53 am
The Austrian Radio Society has put forward a proposal to be discussed at the IARU region 1 conference in September which states:
"In order to provide necessary protection of weak signal users, a footnote to existing 70cm band plan should discourage the use of 436,0 – 438,0 MHz for DATV in national band plans within Europe."
The complete proposal, IARU proposal VA14_C5_35, can be found at various places on the internet including http://www.r-e-f.org//images/Documents/ ... _C5_35.pdf
Clearly the ATV community would not want to see this happen and the BATC has been working with RSGB to ensure they oppose this and we have agreed the following position:
Repeater Inputs and peer to peer is ok
Repeater outputs banned in 435-438 for amsat protection
No specific IARU ATV centre freqs , due to varying national regs/band plans
And to add 70cms/2MHz max into the tech recommendation we had, but lost, at Vienna
The RSGB has a website dedicated to the IARU conference where comment / feedback is welcome http://rsgb.org/main/rsgb-consultations ... sultation/
BATC has also been working with the ATV community in Germany, Switzerland, France and Holland to ensure they lobby their national organisations to oppose the motion.
We have pointed out to AGAF that the German DATV repeater in Munich which has just turned on a 436 MHz OFDM could be a big problem as the Austrians will use that as an example of what will happen and recommend they look at using 10 GHz instead.
A lot of this conference / regulatory work can seem very boring to most of us but it is vital we protect our interests and is just one area where BATC is working in the background to support the ATV community.
