The migration has never been evident. Where has the 31 countries gone that
were active on 137 khz some years ago, certainly not on 500 khz.
The utility stations, although not desireable are not a problem with good RX
selectivity and an antenna suitable for the job.
If the Japanese make some rice boxes for these bands and the appliance
operators get their hands on them then LF/MF will be congested with RASPING
NOISE MODES. At present these boxes are home built and too difficult for
most to construct.

Subject: Re: LF: 136 kHz - Nostalgia
There are two main reasons for the decline in activity on 136kHz.
Firstly, most of those interested in experimenting at low frequencies
have migrated to 500kHz. This is exactly what happened to 73kHz when
the 136kHz band was opened up.
Secondly, the increased sideband noise from utility stations either
side of the band (see DF6MN's grabber to see what I mean)
has dramatically reduced activity from central Europe, particularly
Germany, which was responsible for encouraging other Europeans onto
the band.
There is still activity on 136kHz from far off parts, such as the USA
and Russia and it is to be hoped that some of those who have gained
experience on 500kHz will eventually rise to the challenge of DX on
136kHz.
In the meantime, I am active most weekends on CW and QRSS, and am
available for skeds most days.

==========
I called my head off today on 137 kHz, both on CW and DFCW.
Apart from a QSO with good old Jeff, F6BWO there was nothing heard.
Looking back in my LF log book for around Easter 2006 there were the
following stations active:-
DF6NM, DK4U, DK7SU, DL2HRE, EW6GB, F6BWO, F6CWA, G3AQC, G3KEV, G3WCB,
G3XDV, G3YKB, GM3YXM, IK5ZPV, M0BMU, M0FMT, OH1TN, PA3CPM, PA3FNY,
OK2BVG, RU6LA, S57A . . .
Happy days !
I'm beaconing on 136.915 kHz at present should anyone wish to dust off
and check their LF receivers.
