Hi Laurence,
 
I have looked at my freq lists & there are 2 Datatrak frequencies show= n nearby at 133.20KHz in UK & 133.24KHz in Argentina, having listened t= o the UK one it seems to have a sort of pulsing warble.<= /DIV>
 
Pleased you managed to get the mini-whip parts, I think it is so good I am= mainly using it instead og the G3LNP loop beacauce its not as restricted o= n frequency coverage & so small.
