Since the Perseus is a well known "buddy" meanwhile, only a short information about the

went flawlessly.

Monitoring SW The next step of processing the data required somewhat more patience but

thanks to Bill's tireless help even this rock could be mastered successfully. Bill, a big, warm Thank You for your support!

Monitoring SWA little joke

Forgetting to connect the antenna to the receiver renders even thelongest monitoring session useless!

Refering to my last presentation ...

NationalWhat do we do?

The Goal: Extension of the permissible bandwidth of the currently allocated testfrequenciesInformal contacts to BNetzAFirst results / statements:

Our basic request is understood by BNetzA. A quick response targets to the frequency range 25,7 MHz bis 26 MHz. The unusability of this proposal for tests inside Germany and Europe is understood by BNetzA as 

well. The further treatment of HF licensing implies the inclusion of "all HF stakeholders"

This process can't be awaited! An "at any time revocable license" on a nib (non interference base) on some frequencies was not 

excluded in a recent conversation. This (inofficial) statement makes me feeling hopeful. No doubt: The official, international process has to be started asap and has to run in parallel to 

our (i.e. WG) needs.

... we continued our step by step "broadcast-band" policy andcould score a stage-win:

... and again returning to my last presentation:

My plea:Carry on applying for WBHF licensesLet's mutually exchange the frequency informations"Internationalize" the WBHF frequency licensing process

A Farewell to a large HF Broadcast Site in my Neighbourhood

A short survey of rise and fall of the Wertachtal broadcast transmitter siteLocation:

172SP-T - wir09.09.2014

The Begin

The HF broadcast site has been planned and erected on the occasion of the Olympic Games 1972 in Munich. In the first extension it comprised 7 self tuning 500 kW plate modulated transmitters and a very large curtain antenna field with gains up to 20 dbd

182SP-T - wir09.09.2014

The Prime Time

192SP-T - wir

• 17 transmitters (even DRM) were operating• Many international broadcasters (even VoA)

used the site• In 2009 still more transmitters would have

been required to satisfy all broadcasting time enquiries

09.09.2014

The End

202SP-T - wir

• Due to the decline of HF broadcasting the use of the station decreased continuously

• By 2013 no longer any transmissions took place from there

• The complete station including all antennas will be torn down by end of this month

• The HF broadcast listeners community is sad - we are happy with the prospect of getting WBHF frequencies

That's life

Thank you for (HF) listening!
