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.
