I am very familiar with the shape of my QLN graph and can recognise it easily from amongst a whole section of such graphs.

Earlier I took a look at it from the MDWS site and due to the scaling of the vertical axis of the graph, the prominent noise signals were quite sharp. Upon hovering the cursor at the tip of each noise signal I could read off the respective tone number and noted down the value.

Although I have performed the analysis of such a graph for others, I have never done so for myself. The prominent lower frequency signal emanating from BBC Radio 4, Droitwich, was recognisable "without even looking". As for the others, I decided that the time was ripe to attempt "to name that signal".

Tone Number        Frequency / Hz        Frequency / Hz (Used)        Broadcast Signal and Origin        Power Output / kW

    46                 198.3750                   198                   BBC Radio 4, Droitwich                    500
   161                 694.3125                   693                   BBC Radio 5, Postwick                      10
   198                 853.8750                   855                   BBC Radio Norfolk, Postwick               1.5
   211                 909.9375                   909                   BBC Radio 5, Brookmans Park               150
   238                1026.3750                  1026                   BBC Radio Cambridgeshire, Chesterton Fen  0.5
   244                1052.2500                  1053                   Talk Sport, Postwick                       18
   253                1091.0625                  1089                   Talk Sport, Brookmans Park                400

Making use of the interactive site Medium Wave Radio allowed me to produce the map, below. By factoring in the power output of each signal allows a tentative location for The Cattery to be assigned.

Yes, I think you are correct! 

The two signals from Droitwich indicate England, Wales or N. Ireland but not Scotland.

The signals from Barnstable, Clevedon and Washford tend to indicate SW England (N Devon) or S Wales.

Considering the sizes of the peaks in your QLN graph along with the power output for each broadcast signal tends to point more towards the southern end of The Principality rather than N Devon.
