Hi All,

The following stations are allocated to this range of frequencies:

171     Russian transmitter at Kaliningrad 1.2MW well received here
171     Lvov, Ukraine. 1MW (not heard)  
171     Osipovicy, Bielo Russia. 1MW (not heard)        
171     Moscow, Russia. 500kW (not heard)       
171     Nador, Morocco. 1.2kW (not heard)       
171.875 TV Line Oscillator harmonic (heard)
177     "Deutschlandradio Berlin" Zehlendorf/Oranienburg (100kW 13E24/52N48) 
strong station here
180     Ankara, Turkey. 1.2MW   heard
183     Europe 1 (Saarlouis 2MW 06E41/49N17) very strong here
186 Iceland (not heard) 187.5 TV Line Oscillator harmonic (heard) 188.5 "RAI Due" Caltanisetta/sicily 10kW 14E04/37N30 heard
189     Iceland Broadcast (reported active)
189     Belogorsk, Russia. 1.2MW heard

In addition
162     TDF, Allouis (Radio France Inter) 2MW
is a strong station in Europe.

The one to avoid is Europe 1, Saarlouis, which uses an enhanced mode of 
amplitude modulation with wide sidebands.

Jim M0BMU,>
Thanks for the preliminary information on quieter parts of the 165 - 190 kHz
band.

Mike's request for info reminds me - A while ago, I tried listening
around 184.4 kHz, where the recent "transpac" tests occured, but
this frequency is full of very strong LF broadcast station
sidebands, as is most of 165kHz - 190kHz. But there was a gap in
the general din around 169 - 173kHz that might be worth trying for
VK/ZL to Europe LF tests one day - do others have a quiet spot
here too? Would it be any good for the VK/ZL stations?

ZL stations are permitted to transmit anywhere within 165 - 190 kHz, and
what counts most is using frequencies that have minimum QRM at DX receiving
stations.  Several slots are needed to cope with a number of ZL and VK
participating stations, some of them having good frequency control and
others that drift a few Hz.

The next scheduled "transpac" testing is 22 September.  If EU stations can
agree on what the quietest slots are in the 169 - 173 kHz region are, then
they can be checked for reception in the greater Pacific area as well, and
appropriate new frequencies selected.  I have been co-ordinating the test
schedule and will use feedback from EU receiving checks to discuss with ZL
and VK participants for picking optimum test frequencies for next time.

73, Bob
