About "technical standards": I did not think about AX.25 or other ham radio stuff. I talk about official industry standards, especially the EMC aspects of these.

For example Powerline (or how on your side of the pond the standard to transmit Ethernet signals over the power cabling of a house is called): Here in Germany the shortwave amateur bands must be notched, slightly reducing the capacity of these systems. DARC has a few very engaged people that often have spent much of their professional life with creating such standards. For example Powerline units sold in OE need not be notched.

There is a "round table amateur radio" where all bodies involved with administrative topics around our hobby meet. That starts with several ham radio societies, coordinated by DARC, and includes among others Bundesnetzagentur (our "FCC"), federal government and even German military. The military for example is extremely important for any advances on the 6m band as we are secondary users in the military band 47-68 MHz.

There are also examples what happens when the radio amateurs have no voice that is heard, especially in Scandinavia: In OZ, LA, SM and OH the 70cm amateur radio band is only 6 MHz wide, 432-438 MHz, which created a terrible mess: Relays must use a 1.6 MHz offset, sometimes up and sometimes down. They cannot help but operate relay uplinks in the ISM band!

In OH, two years ago the complete 23cm band disappeared, officially because of the Galileo navigation system. This could have been solved better: SW of Munich, in Oberpfaffenhofen, is one of the command stations for the Galileo system. We had to shut off a few 23cm relays in the Munich area, but otherwise still can use 1,2 GHz.

Do you understand why this is important to me?
