Re: Long-wave stations (historic)
Just on the GPO wire-broadcast system for the United Kingdom Warning and Monitoring Organisation (ROC; Civil Defence) on 72kHz over certain subs' lines. WB1400 / WB1401 receivers for 'Attack Warning Red' messages, tests, etc... Not for use with a domestic radio though.

Today's Polish Radio broadcast on 225kHz, which still matches up with the 'Warsaw' markings on many radio dials, comes from Solec Kujawski which is about 150 miles north west of Warsaw. That station replaced the ill-fated 'Warsaw Radio Mast' at Konstantynów, once the world's tallest structure. There's an excellent website about that transmitter, in Polish but readable via Google Translate, at: http://www.rcnkonstantynow.pl/boveri/ I particularly like the Solartron CD1400 scope visible in the pictures. How on earth did that end up there? It's interesting to see what's behind the markings on the radio dial. Chris

When I used to listen to the external service it was always "Polish Radio Warsaw", which sounded a bit odd in English. It's as if they do language syntax like they do mathematical notation.

Re: Long-wave stations (historic)
Dave,
Radio teleswitched control of Economy 7 is still in use, but I don't know how many installations remain in service; I have one. The system has the provision for other channels, though whether any others were ever used I don't know |

Re: Long-wave stations (historic)
Hi, I have just been looking in my 1955 copy of the Radio Servicing Pocket book (E.Malloy & J.P.Hawker) which shows the long and medium and FM allocations granted under the Atlantic City Conference of 1947.
I hope this is of interest. Regards Trevor. |

Re: Long-wave stations (historic)
The Third part of that must surely date from 1955, since the BBC FM(VHF) Network is listed, which, AFAIK, didn't begin operating until 1955.

Re: Long-wave stations (historic)
Livewire, you are probably correct as the book was published on 1955. However I don't know how far in advance of 1955 the UK FM frequencies were agreed.

Re: Long-wave stations (historic)
Just to add to Paul’s post. A couple of years ago when camping I had to buy a portable radio having left mine at home. The radio was badged Siemens and not much bigger than the palm of my hand.This radio had FM and LW only and reception on LW was and is astounding. In fact beyond belief. Tuned Radio 4 from South of France to Italian Riviera perfectly at all time of day.

Re: Long-wave stations (historic)
Two-band radios in France often used to be LW ("GO") and FM, as opposed to the more usual MW/FM pairing seen in the UK. I actually bought myself a cheap "boom box" like that while working in France in 1993, but ended up giving it away.

Re: Long-wave stations (historic)
I dug out my 1938 copy of "The Wireless Constructor's Encyclopaedia" by F.J.Camm. It reproduces the "World Radio List" of European Longwave Broadcast Stations:
Kc/s Metres kW Station 152 173.5 5 Ankara (Turkey) 153 1961 7 Kaunas (Lithuania) 160 1875 150 Hilversum 1 (Holland) 160 1875 150 Radio Romania (Romania) 166 1807 150 Lahti (Finland) 172 1744 500 Moscow 1 (USSR) 182 1648 80 Radio-Paris (France) 185 1622 5 Istanbul (Turkey) 187.5 1600 20 Irkoutsk (USSR) 191 1571 60 Deutschlandsender (Germany) 200 1500 150 Droitwich (England) 208 1442 35 Minsk (USSR) 208 1442 16 Reykjavik (Iceland) 216 1389 150 Motala (Sweden) 217.5 1379 100 Novosibirsk (USSR) 224 1339 120 Warsaw 1 (Poland) 232 1293 150 Luxembourg 232 1293 100 Leningrad 1 (USSR) 240 1250 60 Kalundborg (Denmark) 240 1250 0.5 Vienna Experimental (Austria) 248 1209.6 100 Kiev 1 (USSR) 253 1186 10 Vigra (Aalesund) (Norway) 256.4 1170 25 Tashkent (USSR) 260 1153.8 60 Oslo (Norway) 271 1107 100 Moscow 2 (USSR) 282 1064 10 Tromso (Norway) 283 1060 35 Tiflis (USSR) 340 882.3 20 Saratov (USSR) 347 864 10 Finmark (Norway) 350 857.1 10 Archangel (USSR) 355 845.1 20 Rostov-on-don (USSR) 359.5 834.5 18 Budapest 2 (Hungary) 375 800 40 Sverdiovosk (USSR) 390 769 10 Voronezh (USSR) 392 765 0.6 Boden (Sweden) 392 765 30 Banska-Bystrica (Czechoslovakia) 401 748 1.3 Geneva (Switzerland) 413.5 726 100 Moscow 3 (USSR) 413.5 726 0.6 Ostersund (Sweden) 431 696 10 Oulu (Uleaborg) (Finland) It's noticeable that many of the Transmitter powers are comparatively low. The ones above 375 Kc/s (below 800 m) are outside the usual tuning range, but I guess receivers were different in the countries using them. When I was growing up in the 1960's, colourful radio dials with their strange names were a source of endless fascination for me - leading to a lifelong interest. |
