I took a listen down on 136kHz last night Chris, using my 500kHz 
resonant vertical and my Datong UC/1. I heard you calling CQ on CW, and 
presumably you also on QRSS something or other a bit later. The antenna 
of course was WAY off resonance so you were pretty weak - DCF39 was 
only s8.

This morning I tried resonating the vertical on 136 using the old 
'bucket' inductors I used when I was last on the band, which are still 
in the dustbin by the vertical. The resulting 9.8mH should according to 
my calculations have brought it to resonance on around 136, but my 
AA200 shows no resonance only a very slight dip at 400kHz and it now 
seems even worse with DCF39 only s7...

I shall be racking my brains over the next few days over why the theory 
doesn't seem to work! This will be receive only, I have no plans to get 
transmitting again as my old transverter is very much in bits nowadays.
