Re: LF: Re: 136 kHz Tonight

Chris,

Your CQ call on 136.5kHz at 7pm was copied at 559 here on the earth electrode antenna and straight into the FT817, which is deaf on 136kHz. I'll send you the recording.

No TX gear on the band  ....yet.

GMT               MODE    QRG

18.00 - 18.20  CW     136.5 kHz

18.20 - 18.40  RTTY  137.5 kHz

18.40 - 19.00  QRSS  137.7 kHz

19.00 - 19.20  CW      136.5 kHz

19.20 - 19.40  RTTY  137.5 kHz

19.40 - 20.00  QRSS  137.7 kHz

 

Calls / reports welcome as always.

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.
