Transatlantic on 136 KHz

>From Peter Dodd, G3LDO
You may have received the following e-mail regarding amateur test
transmissions in the 136kHz band.
"Our experiments on 136kHz in Europe show that distances of
over 1000miles can be achieved fairly regularly (on aural CW). I have
worked OH1TN several times cross band on 137kHz/80m several times and
2-way on 137kHz once. The distance is 1860km. The openings are
usually, but not always, fairly short.
It would seem that a trans Atlantic path is possible on 136kHz.
To test this out I will be sending test transmissions on 137.5kHz
from 2300UTC until 0600UTC every evening that the weather permits
from tonight onwards. These transmissions will be very slow morse
with a dot period of about 3 seconds and will just be my call G3LDO
repeated. This transmission would be visible on a computer waterfall display.
Our experience indicates that 137kHz band conditions are good when
160m conditions are good..
If you are interested perhaps you could let me know if the frequency
I have chosen is reasonably clear. The band is from 135.7kHz to 137.8kHz."
I have been transmitting on 137.4kHz in slow morse when the situation
allows but so far no reprorts or even an e-mail as to if anyone is
interested. I think it might be better if I can find someone who is
interested and arrange the transmissions to their conveniance. For
example is the frequency band usable at the USA end. If so what is
the best frequency between 135.7kHz to 137.8kHz? What is the best
time? A good propagation marker is probably the BBC long wave station
Is anyone interested? It could eventually result in a cross-band QSO.
