laser 558 communicatorAs a child, the medium wave band was a mysterious place replete with strong international broadcasters such as Radio Sweden International, Radio Moscow and the BBC, and who could forget the thrill of tuning into the medium wave pirates of the past, whether it was Radio Caroline in the 1960s, the land based pirates such as Radio Jackie in the 1970s, or Laser 558 in the 1980s. Being something of a radio back-water these days, the medium wave band is not something that Wireless Waffle has paid much attention to. So on a recent night-time road-trip where there was little else to do, the journey was shortened by the unforgiving task of working the way along the medium wave dial to see what was there these days.

flevo mw transmitterIt is evident that the UK still has a prestigious number of medium wave stations, though many are geared towards older listeners (whose hearing is no doubt so frequency constrained that the limited bandwidth of AM sounds just as clear as FM) and whose service area is relatively limited due to the lower powers used (most UK local AM stations have transmitter powers around 500 Watts). At night, however, is when the band comes alive and stations from all over Europe (and even further afield) become audible. Tuning around at night reveals one key fact: Spain appears to be the king of the medium wave band. On almost any clear frequency, it is the Spanish radio stations that seem to dominate. Germany has now ceased medium wave broadcasting, and there are a diminishing number of stations in France and the Netherlands (even stalwart Radio 538 on 891 kHz recently closed down just a couple of weeks ago on 26 October).

Of course, when driving it's difficult to simultaneously look up what stations are on a particular frequency (unless you have a willing passenger) so any interesting stations and frequencies have to be committed to memory for later research. One such station and frequency that sprang up was I Am Radio on 1350 kHz. At the time of listening, it was playing almost non-stop obscure disco tracks with occasional announcements and news (from NPR) in English and the odd announcement in Italian. It is the Italian language announcements that give a clue as to the station's provenance, and a bit of web-searching later revealed that the station is 'semi-pirate'. Exactly what this means is not clear but it seems to suggest that it is not a totally legitimate organisation.

i am radio 1350 amThe signal on 1350 kHz is surprisingly strong, given the stated night-time transmitter power of just 1 kW (though there are rumours of an increase to 50 kW being due). And as the frequency is almost completely clear of interference from any high power transmitters in Europe (if you exclude the 850 kW mammoth or TWR Asia in Armenia), reception is surprisingly good. If obscure disco and news from the USA is your thing, why not give it a try. They claim a contact address of 'info@iamradio.am' though the associated web-address only yields a parking page.

But coming back to the question of which European country rules the medium wave band, Wireless Waffle has conducted an analysis of the stations currently on air to find out which country uses the most frequencies and which country emits the most power into the ether, based on data from MW List.

The answers are maybe not that surprising. The top 10 European medium wave countries in terms of the numbers of frequencies used (out of the 120 possible channels from 531 to 1602 kHz inclusive) are as follows:

PositionCountryFrequencies Used
2United Kingdom68
5The Netherlands10
7=Czech Republic8

So Spain really are medium wave royalty, if the number of frequencies in use is the measure. But what about if the total amount of power radiated into the ether is taken into account. The results look as follows:

PositionCountryPower Emitted (kW)
2United Kingdom4130
6Czech Republic1150

spain retains crownSpain retains its crown as the top medium wave transmitting country in Europe with over 5 MegaWatts of radiated power, but some surprising new countries appear lower down the top 10. Hungary jumps from joint 10th to 4th. France has only 3 medium wave frequencies in use but as one of these is the behemoth 1000 kW transmitter of TWR Europe on 1467 kHz this dwarfs many of the other countries who have a greater number of transmitters but of much lower power. Belgium has only 2 active medium wave frequencies but at 300 kW, RTBF International on 621 kHz tips the scales in their favour to bring them in at (this week's) number 10.

dab technologyWhat does this tell us? Nothing in particular, and definitely nothing of any use or value, it's just a somewhat pointless academic exercise. But it does suggest that if you are a manufacturer of AM transmitters, you should undoubtedly aim to site your offices in London, Madrid and Bucharest. Or that if you are learning Spanish, you might do well to buy a medium wave radio and tune around the band at night!
