The strongest signal that I have ever heard on 136 khz. 7S6SAJ was S9
plus plus with his 210 metre high antenna. The only other signal on the
band nearly as strong is MM0ALM. Who says large antennas are not
necessary and have little advantage over loops or low slung long wires
!!!! When EI0CF was using his work QTH antennas he was also an extremely
strong signal. These stations are only using modest output rf power.
Chris might be using higher power but the antenna launching the signals
is the prime factor.
I heard numerous UK and other EU stations calling but did not succeed in
making a qso. With an antenna like that also on receive one wonders why
they were not heard. In the light of this experience the chances of a
transatlantic qso are nil except those interested make an effort to
improve the antenna height. Increasing the rf power, although helpful is
not the ANSWER.
