Back in the day you could receive BBC4 on MW at typical GA FL all the way to Lausanne. There was probably also an MW station broadcasting the test matches. Ex Kipper fleet crew (Coastal Command) seem to have a high proportion of cricket fans :)
Replacement with a younger model can turn out to be very expensive.
I replaced my ADF with a much younger model due to a fading display, and BBC Radio 4 is now perfectly listenable to. Problem solved 
ANT as suggested by Tumbleweed is noticeably better. I’ll have a play around and find what’s interesting in the 200-1799kHz range.
The Pooleys radio navigation book says it’s very unprofessional
It forms one of the validation steps. If an order to launch is decoded, they check Radio 4, and if broadcasting, they do additional checks.

BBC Radio 4 still puts out half a megawatt on 198kHz long wave from Droitwich. There’s an anecdote floating around that Royal Navy subs surface and check 198 periodically as a check that the UK hasn’t been destroyed. Whether that’s true or not I don’t know.
That’s amazing.
The old radios (which lots of people had in Czechoslovakia, but had to be careful with who saw them) had these old station names printed on the dials.
Of course no radio would have Voice of America or BBC on it – straight to jail 
One needed more power because the communists were jamming these.
I would expect an ADF to receive any station which uses AM. That is how the ident is encoded.
US AM stations put out up to 50 kW power, AM radio is not big business any more in the age of the Radio Garden etc app. Stations in Mexico and Bonaire, intended for US and Caribbean audiences do put out more power.

Sound quality on our older adf’s are very dependent on good antennae. If you have the external wire ant, try cleaning the connection points on the feed thru as well as the wire itself. I know some units had a combined sense/loop unit, in witch case you may have to live with whatever sounds you get. The King was a common and good unit. See what you can do. Of course, in the states we have stations that put out 500000 watts, those come thru no matter what. lol carl
Last years we listened RTL (234) during my IRME renewal with my fellow instructor., a very nice flight :).
Used to listen to the BBC on 198 KHz probably 200Khz in those days up to a 1000 miles from the UK. Beter than Radio Luxembourg or Caroline
