4 Status Monitoring Activities The Setup SP-T - wir

5 Setup 4 2SP-T - wir

6 Setup... works... and has been the least challenge! Since the Perseus is a well known "buddy" meanwhile, only a short information about the "Non-HFIA-Standard-Antenna" ROHDE&SCHWARZ HE 011 will be given subsequently: 5 2SP-T - wir

7 Setup 6 2SP-T - wir

8 Monitoring SW  Implementation and putting to work of WBHF_Channel_Availability_Measurement.exe went flawlessly. 7 2SP-T - wir

9 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! 8 2SP-T - wir

10 Monitoring SW A little joke Forgetting to connect the antenna to the receiver renders even the longest monitoring session useless! 9 2SP-T - wir

11 Next Steps Returning to our today's Agenda ı General Discussion / Issues to address ı · Review of process014.c ı · Storage of results / Presentation of results ı · Other? 10 2SP-T - wir

13 Licensing Issues Refering to my last presentation SP-T - wir

14 National What do we do? The Goal: Extension of the permissible bandwidth of the currently allocated testfrequencies  Informal contacts to BNetzA  First 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. 13 2SP-T - wir

15 Licensing Issues... we continued our step by step "broadcast-band" policy and could score a stage-win: 14 2SP-T - wir This frequency formerly has been used by Bayerischer Rundfunk our regional broadcaster!

16 Licensing Issues... and again returning to my last presentation: My plea:  Carry on applying for WBHF licenses  Let's mutually exchange the frequency informations  "Internationalize" the WBHF frequency licensing process 15 2SP-T - wir

18 A Farewell to a large HF Broadcast Site in my Neighbourhood A short survey of rise and fall of the Wertachtal broadcast transmitter site Location: 17 2SP-T - wir

19 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 db d 18 2SP-T - wir

20 The Prime Time 19 2SP-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

21 The End 20 2SP-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!

22 Questions? Thanks! 2SP-T - wir
