Wireless Waffle - A whole spectrum of radio related rubbish
All Time FM DX Logbooksignal strength

FM DX LogbookThere are those occasions when you happen across a radio stations that's clearly not local. And if there is a Sporadic-E opening, it soon becomes apparent as the local station is wiped-out by stations from much further afield. On these occasions, it's fun to tune around the FM band and see what DX stations can be heard which can be done at home, or when on the move. It seems FM radios in cars are paricularly adept at receiving stations from amidst the background noise and mush.

Here's a list of the DX stations that have been recorded by the Wireless Waffle team over the years. The 'Location' column shows where reception took place (often on a motorway or at a service station or similar!) It just goes to show that in the right conditions you don't need fancy equipment or enormous antennas in order to enjoy the age old art of radio DXing. The 'RDS' column only shows the station's RDS name where it was successfully decoded - in other cases identifying the station was done using a different method (see below).

NOTE: The logbook has been filtered to remove records which are everyday occurances. For example, from the south coast of the UK, it is not unusual to receive stations from France which is, after all, only 30 or so km away in some places. Only examples where reception is out of the ordinary are now shown. In addition, where the same station has been received from multiple locations, only the one which is furthest away from the transmitter site has been included.

Propagation Loss

In a previous article on Wireless Waffle the idea that the path loss for tropospheric and sporadic-E propagation might yield a pattern was discussed. In order to see whether this holds true, the image below shows, across the x-axis, the distance of each station from the receiver and the y-axis shows what the signal strength (in dBm) would be if that station had been received in free space would be. This takes account of the transmitter power, the distance to the transmitter and the frequency.

signal versus distance chart

The hypothesis made in the article is that the path loss for signals received through tropospheric ducting were clustered around -40 dBm, whereas those received via Sporadic-E are clustered around -65 dBm. As the same level of signal is needed to receive a signal, this suggests that the path loss via Sporadic-E is actually 25 dB lower than that through tropospheric ducting. Take a look at the graph and see what you make of the results.

Monthly Considerations

It is often cited that Sporadic-E propagation occurs primarily in the summer months, with occasional occurrances in the winter (in the Northern Hemisphere anyhow). To try and see whether this pattern occurs from the loggings here at Wireless Waffle, the chart below shows the number of times that each type of propagation has occurred in which month of the year. It does seem to support the summer/winter Sporadic-E seasons, and the fact that tropospheric propagation occurs fairly evenly accross the whole year (as no pattern can be seen).

months of reception

How do you know what station you're hearing?

Identifying 'DX' radio stations (especially ones in a foreign language and extraspecially whilst driving a car) is not necessarily that easy. However, the wonders of RDS have made life much more straightforward. If the station is strong enough for the RDS to appear (which assumes it is sending an RDS signal in the first place) then noting the frequency and the RDS station name is often sufficient to make a reasonable identification - the only problem that then arises is if there are multiple transmitters of that station on the same frequency (i.e. for a national network) in which case it's much more difficult. The best bet in this instance is to trawl the internet and see what stations other people with more sophisiticated equipment were hearing and see if you can match up your log with theirs.

If there's no RDS, but you hear a station ident or jingle and can catch the name, this is almost as good as the RDS. But in some cases (i.e. if it's in a language that you are completely unfamiliar with like Arabic or Turkish) you might not be able to tell the difference between a jingle and an advert or even make out the station name.

Another method, if several stations are audible, is to look and see if there those stations could potentially come from the same transmitter site. FMScan can help with this. If, say, you can hear Fun Radio on 88.9, SkyRock on 92.7 and France Bleu Nord on 95.5, with a bit of digging you will discover that all three frequency and station combinations come from transmitters in and around the Boulogne area of France, and therefore it is highly likely that this is where the transmissions are coming from.

If all else fails, try and note the language and the frequency. Together with the list of other stations you heard, this might just be enough to make an identification. For example, RTA Chaîne 1 on 87.8 in the log above, was identified from listening to the programme and hearing the word 'Al Jaza'ir' (Algeria in Arabic) and a few smatterings of French (remember that the French colonised Algeria for 130 years and thus it's a language that's still spoken there) in amongst the otherwise incomprehensible (to a non speaker) Arabic clatter. From this information and the fact other stations from mid and western Spain were being heard, there's a fairly safe bet that it was from Algeria. A check on the web shows only one station in Algeria on 87.8 and so the identification is complete. Of course it could have been Morocco, but thankfully there were no stations on 87.8 in Morocco at the time (according to the web) and given the direction of other stations being received at the same time (i.e. the fact no Italian stations could be heard), it was very unlikely to be Tunisia. Another Arabic station on 88.4 was heard at the same time but there are two transmitters in Algeria on 88.4 and there is no way of knowing which it was that was being heard - so this logging can't be confirmed and doesn't appear above!
