LF: 73 kHz tests

["peter cleall" <peter.cleall@virgin.net>]

Listened  and viewed all morning.

Nothing heard,  A few very weak traces seen, between the 60kHz related
lines.

Rtty midband off for long periods and 60kHz on at all times, in spite of the
pundits predictions.

So it's back to 136kHz and try and improve the reception on that band, at
least it will continue to be in long term use.
