Radio on airwaves didnt come untill the late 90-ies

Thats not true. Happy Radio RTL and others came on terrestrial frequencies in 1993 with temporary experimental licences. Radio 10 had a 'temporary residual frequency in Noord Holland; others too were allowed, in a small way.

In January 1994, FM and AM licences were finally awarded:
1. Classic FM
2. RNN - Radio Noordzee
both had networks (packets) of FM licences giving almost national coverage.
Three high power AM licence were also awarded -
3. 675 kHz, which went to Radio 10 Gold,
4. 1395 - awarded to Elle, who bottled launching.
5. 1224 and 828, which went to Veronica (but they were still part public so had to hide behind the image of Holland FM, using the MV Communicator on AM for a while. A long story!).

Radio 10 Gold on 675 launched four days after the offer of their licence (that is, in January 1994) using an old Nozema transmitter that was previously Hilv' III, which had moved to FM by then.

I was involved in some of these, especially Classic FM, which I wrote the application for and represented it to the Ministry.
I also reconditioned and commissioned the 675 transmitter.

I remember well the meetings with the two lady ministers - Mai Weggen was one and how we (as Classic FM) schmoozed them by offering a few hours a day of jazz music, which they were fans of. Many of the dates are on contracts which I still have copies of, so I know the dates are correct; mostly 1994.

Ruud also says: when the European rule was applied that ALL channels not used by a public broadcaster MUST be put available for commercial radio. Many countries neglect this rule.
That's true, but we used that rule in 1995, when we made a legal action in the courts to "liberate" the 100FM frequency from Radio U in Utrecht for use by Sky Radio, using 100kW ERP. (Sky got nothing in the first round of frequency awards ion 1994).

Many countries ignore this because no one tried to force them to allow the frequencies to be used. It needs some financing for the right kind of legal case. Such actions are very expensive. The problem in the UK is, the only people with the big funds are too scared to jeopardise their other licences.
It is a big putty.

But the fact is, land-based, privately-owned commercial radio came to the Netherlands in the first half of the 1990s. Ruud, I think you were a part of the Radio Nederland Wereldomroep at that time still? Maybe you have some old 'actuality' of a news report?
