Back in the beginning when 137 started in the UK
and EU many years ago here were about 37 countries active on CW and
later QRSS and I worked them all.
The USA was not permitted to operate 137 in
those days and I used to QSO with them xband, they would reply to me on
7030 Khz CW. The norm for me was to TX QRSS speed between 3 -
60
depending on propagation at the
time.
My normal CW SIGNAL was heard at 579 at best
by NC1K, VE1WW and others including a /MM report off the east coast USA. To the
east I worked RN6BN several times on normal CW plus others around
Moscow.
One other stn heard frequently in the
USA/CANADA at that time was MM0ALM.
My TX was home built using 4 FETS in the
PA class D about 1W erp output.
The antenna was 3 x inv L in parallel each one
was 100 feet vertical and 450 feet horizontal.
loading coil was less around 500uH.
I still have the same system today but seldom
work 137 anymore since it has gone all digital and virtually no CW anymore also
the number of countries has diminished to just a few.
Since the introduction of digital modes on this
band some time back most CW operators have left and gone
elswhere.
I work 472 Khz at present and have worked the
USA in the past on 500 Khz CW plus others around EU.
On this band I use 5W erp and the antenna is a
1/4 wave inv L up at 100 ft vertical and the rest horizontal
I have kept some logs/records of past
acty. Another stn that used to be active was VE1JG on both 137
and 500.
I hope this info might be useful to you and others.
This is what I remember without delving back through logs and other
records.
I have now replaced the hd/brew LF
tx with a modified DECCA 5501 plus a spare both seldom used
!!!!

Hi Bob,
>I wonder
if you or anyone has worked T/A with CW by ear on 137?
I don't think anyone has ever made a cw contact by ear across the
Atlantic, but I've gotten sporadic reports over the years that my signal
is occasionally audible on a signal peak, but the peaks are not really
predictable. Also, I don't have a quiet enough QTH to hear 137 kHz signals
over that distance. Best bet would be if Joe VO1NA ran some power - he
has an easier and shorter path to Europe.
